Recently accidents involving lifeboats and launching appliances have increased
in number as many as 125 accidents took place between 1989 and 2003 salting in
12 persons losing their lives many of these accidents which took place during
regular on board drills can be attributed to lack of knowledge lack of
experience and poor maintenance of the device by the crew typical causes of
accidents include improper resetting of the lifeboat release device inadvertent
operation of the release handle and cable rod malfunction following a spate
of incidents the soleus Convention was revised and as of July 2006 annual
inspections servicing and repair are to be conducted by the manufacturers
representative or a person trained and certified by the manufacturer in this
DVD program you will be shown operation and maintenance fundamentals for various
types of life-saving appliances with a focus on accident prevention the
guidelines introduced are general in nature for a specific model or product
users are strongly advised to refer to the instruction manual provided by each
manufacturer
standards specifications and functions applying zat lifeboats are strictly
regulated by the sonís Convention lifeboats covered by the 83 amendments
include partially enclosed lifeboats totally enclosed lifeboats and totally
enclosed fire protected lifeboats that are equipped with water spray systems
and air supply devices
most lifeboats used on modern general merchant ships are of a totally enclosed
design ie they are covered with a canopy and have a propulsion engine as for
passenger ships partially enclosed lifeboats are the most common ships with
highly flammable cargo for handling toxic materials carry fire protected
life wounds all lifeboats have both off load and unload release functions
simultaneous release of both ends is possible following enforcement of the
1996 amendment to the LSA code all lifeboats are provided with an interlock
mechanism to prevent accidental release before the lifeboat is waterborne
totally enclosed lifeboats are usually launched using gravity type Dartmouth's
however all bulk Carians built after July 2006 are required to have free fall
launching devices
to provide you with a better understanding of the structure and
operations of various kinds of life-saving equipment on this DVD we
will deal with lifeboats
life rafts rescue boats lifejackets
immersion suits distress signals and other accessories
gravity type davits swing a lifeboat outward and lure it into the water
they consist mainly of a pair of frames davit arms are lashing device boat Falls
suspension blocks and both winches the
lifeboat is lowered at a constant speed using its own weight by operating either
the remote-control wire inside the lifeboat pull the remote control lever
on the ship's deck let us take the closer look at lowering and launching
operations for totally enclosed lifeboats with gravity tight planets
prepare a set of transceivers and confirm that communication is possible
also confirm that the cable for the storage battery charge has been detached
confirm attachment of the painter to the lifeboats painter release device the
painter should be connected to the bit of the parent ship as far forward as
practicable
move the over lashing wire ropes if fitted some vessels are not equipped
with over lashing wire ropes over lashing wire ropes once removed
should be kept together but far enough away to prevent entanglement with the
lifeboat tangling of the rope with the lifeboat could lead to a serious
accident the auto trigger wire rope comes off automatically when the
lifeboat is swung out pull out the safety pin to release the boat winch
break pull out the it arm stop safety pins both fore and
aft and release the stop by pulling down the handle in one continuous motion
confirm that the remote control wire has been drawn into the lifeboat then open
the access hatch and get on board once inside the lifeboat immediately fit the
bottom plug
open the fuel valve and the cooling sea water valve
and close the drain valve on the exhaust pipe then confirm that all crew on board
have fastened their seat belts the operator starts the engine and pulls
down on the remote control wire to swing out the lifeboat
once swing-out is complete fully pull down the remote-control wire the
lifeboat will descend at a fixed speed using its own weight as the lifeboat
approaches the water's surface the operator should alert the crew about
impending splashdown
avoid rapid swing outs or abrupt halts during the swing out operation as this
can have a dangerous impact on the boat inching operation is also dangerous
since it shakes the lifeboat life boat swinger and lowering operation can also
be conducted using the operation lever on the deck of the parent ship there are
two types of release for launching a lifeboat
one is the offload release the standard method of launch and release and the
other is the unload release which is to be conducted in emergency situations
only when the lifeboat is fully water borne and there is no load on the
release hook carry out offload release
when the lifeboat is not fully water borne and there is a load on the hook
unload release shall be performed
the release care system comprises a pair of release hooks located fore and aft of
the boat a release handle on the side of the steering seat a pair of control
cables a hydrostatic unit to prevent the lifeboat from plunging due to
mishandling and an interlocked cable there are two types of hydrostatic unit
a direct system that controls detected water pressure directly through an
interlocked cable and an electric type that electrically controls the interlock
lever with pressure signals to operate the relay and the solenoid the interlock
mechanism which prevents a mishandled lifeboat from falling before it is fully
water borne became mandatory for all lifeboats under the so last 96 amendment
the offload release is an operation conducted when the lifeboat is fully
water borne and there is no load on the release hook prior to conducting this
operation the following should be confirmed no ropes or lines are
entangled on the fore and aft release hooks the lifeboat is fully water board
the engine has been started
and finally all crew are in their seats with their seatbelts fastened after all
this has been confirmed the operator releases the safety lock device pulls
out the release handle safety pin and pulls the release handle to the fully
open position in one continuous fraction
some release gear systems do not have a safety lock device in normal situations
the interlock unit detects the water pressure and releases the interlock when
the boat is afloat so it is possible to carry out an offload release using the
release handle however in the event that the hooks have not released it is
necessary to conduct an unload release
the unload release should be reserved for emergency use only when the hooks
are not released due to malfunction of the hydrostatic unit all when seas are
rough and normal offload release is not advisable to conduct an unload release
first open the cover of the interlock device fully raise the hydrostatic
interlock lever and while holding it insert the securing pin to release the
interlock then release the safety lock device next remove the release handle
safety pin and pull the release handle to the fully open position in one
continuous action
some release gear systems do not have a safety lock device release the painter
and immediately get clear of the ship
now let's look at the recovery operation at least three persons are required for
this operation accidents involving lifeboats often take place during
recovery of these accidents seventy percent are due to improper resetting of
the release gear and such mastering the proper way to reset the release gear is
extremely important properly resetting the release hook is
an essential part of every recovery operation improper resetting may lead to
the lifeboat being held by only one hook or even falling resulting in a fatal
accident
there are various types of release hooks regardless of type improper resetting is
indicated when the safety pin cannot be smoothly inserted or when extra force is
required to return the release handle to the set position if you have any doubts
about the resetting operation start over and redo each step in the process to
reset the release hooks begin by pulling the release handle upward for about 30
degrees next simultaneously lift the fore and aft hooks after ensuring that
the hooks have been reset properly insert the safety pin
finally reset the safety lock device and to make sure that it is in the locked
position the safety pin cannot be inserted unless the release handle is in
its locked position the reset procedure is the same no matter which type of
release hook you are dealing with lift up both the full and aft hooks and swing
down the release hook reset levers the release handle is automatically reset
confirm that the release handle is fully reset and insert the safety pin next
insert the winch handbrake safety pin
the lifeboat until it is under the boat falls using the winch adjusts the
suspension links to the proper height
simultaneously connect the suspension links to both the fore and aft hooks
operate the winch using a remote controller and begin hoisting stop
hoisting the lifeboat when it is just clear of the water and confirm that the
fore and aft hooks are properly connected also confirm that the
hydrostatic interlock lever has been moved back to the locked position
resumed hoisting when the davit arm approaches the stowed position the davit
arm strikes the limit switch and the boat winch stops automatically only
after it has been confirmed that the winch has stopped completely may the
crew disembark the lifeboat place two persons on the davit platform to oversee
proper stowage when the winch stops automatically manually hoist the davit
arm confirm that the davit arm is in contact with the platform stop and cease
winding the aware of over winding do not forget to detach the manual hoisting
handle once winding has been completed
immediately reset the davit arm stop and insert the safety pin in the davit arm
stop handle
after removing the handbrake safety pin lower the suspension blocks on the davit
horn by releasing the handbrake if the suspension blocks are not on the Taffet
horn the boat Falls will remain under tension and may be damaged
insert the handbrake safety pin be sure to turn the end of the safety pin
install the auto trigger wire rope and use turnbuckles to tighten it
install and tighten the over lashing wire rope
the painter should be kept attached to the painter release hook at all times
you
find protected lifeboats are totally enclosed lifeboats with water spray and
n supply systems and are carried on ships such as tankers
the water spray system on fire protected like books effectively cools the surface
of the boat in Berlin in order to protect the hull surface from fire
damage and the cabin from high temperatures thereby enabling the
lifeboat and the crew to evacuate to a safe sea air if fire breaks out near the
parent ship following an accident the system protects the microbes and fruit
for at least eight minutes the spray system pumps seawater with a spray pump
ejecting it from nozzles on the external surface of the boat cooling the hull
before starting the operation be sure to close the hatches and other openings and
confirm that the main engine is idling when preparations are completed increase
the RPM of the main engine and begin spraying the air supply system protects
the crew when they encounter a fire on the seat or are in an environment filled
with toxic gas in escaping from hazardous area all lifeboat openings are
closed the system provides clean air sufficient to operate the main engine
and sustain the crew for not less than 10 minutes
you
containers of highly compressed air found inside the lifeboat supply air to
the lifeboat via a pressure regulator
during use the valves on every compressed air container and the
pressure check stop valve have to be opened
confirm that pressure for air containers is maintained at the primary pressure
gauge level indicated on the high pressure side of the air regulator while
observing the secondary pressure gage level on the low pressure side of the
air regulator adjust the pressure using the regulators handle so that the in
boat differential pressure indicator shows a pressure slightly higher than
the external air pressure check that the air is being discharged
now let's look at the freefall lifeboat system all bulk carriers of 500 gross
tonnage and upwards built on or after July the 1st 2006 are required to have a
freefall lifeboat free for lifeboats are placed at the ship's turn
in the event of an emergency the crew board the lifeboat in its stowed
position and then conduct a freefall launch the launching operation can be
performed from inside the light
the davits unit of a freefall lifeboat consists mainly of a slight rack add
avid arm a pair of suspensions a hydraulic cylinder and a lashing device
the winch is composed of a wire drum a hydraulic motor speed reduction gear and
hydraulic brake gear
prior to launch make sure that the water surface is free of obstacles
release the lashing line and confirm that the lashing plate has been released
the lashing plate will be released automatically once the lashing line is
released
if the lashing plate is not released release it manually
using the attached nylon rope next check that the battery charge cable has been
detached
remove the release hook safety pin and open the rear hatch
ferm that all necessary launch preparations have been completed the
crew should then board the lifeboat from the rear hatch
finally the Coxon boards the lifeboat and closes the hatch tightly from inside
after everyone is on board confirmed that the boats drain valve has been
closed all crew members should be seated should fasten their seat belts and
should grasp the handrail on the seat in front of them do not forget to use the
headrest belt if it is available the operator should conduct a final check to
confirm that all crew members have fastened their seat belts and that they
have not put on life jackets then the operator may be seated and fasten his or
her seat belt when doing so please avoid touching the release lever the operator
starts the engine removes the release lever securing pin and closes the bypass
valve pumping the release lever several times releases the main lashing allowing
the lifeboat to achieve freefall launch
once the launch has been completed immediately leaves the parent ship for a
safer area never use a painter during a free fall launch in the event the
hydraulic system does not function properly and emergency release is
required confirm that the bypass valve is open break the acrylic cover insert
the emergency release handle and turn the emergency release bolt clockwise
until it comes to a stop the stopper of the main lashing will open and the
lifeboat will be launched when a freefall is not possible due to
insufficient water depth or when the ship is in an inappropriate area from
freefall it is possible to lower and launch the lifeboat using David Holmes
when launch preparations have been completed and confirmed switch on the
hydraulic power bank operate the control lever to lower the Traverse and
subsequently remove the hook lashing lines attach the wire ropes to
the suspension
using the lever position the data turns just above the boat lifting position and
adjusts the fore and aft balance of the lifeboat the crew members embark the
lifeboat from the rear hatch take their seats and fasten their seat belts each
member should grasp the handrail on the seat in front of them the operator then
boards the lifeboat and closes the hatch the operator confirms that all crew
members have fastened their seat belts and then removes the pin securing the
release lever and closes the bypass valve pumping the lever several times
releases the release hook and removes the main lashing after visually
confirming that the main lashing has been released the operator on the main
ship shall use the control lever to swing the davit arms to the proper
lowering position and then lower the lifeboat
when the boat is waterborne and has become well-balanced the operator
onboard the lifeboat shall indicate to the operator on the parent ship to stop
loading the boat the operator on board shall remove the wire ropes used to
suspend the vent and attach them to the plate providing the boat engine can now
be started immediately leave the area of the main ship switch on the hydraulic
power pack on the parent ship
the operator on deck uses the control lever to swing out the data tones next
lower the suspensions to a height allowing the wire ropes for hanging the
boat to be attached these steps should be carried out under instruction from an
operator onboard the lifeboat the operator onboard the lifeboat attaches
the wire ropes to the suspensions after signaling to the operator on deck the
operator on board the lifeboat should be seated with seatbelt fastened and should
stop the engine the operator on deck confirms that the engine has been
stopped and starts hoisting the boat the movement of the Traverse should be
halted prior to coming into contact with the hinge block and the wire rope
support by operating the control lever stow the davit arm to the boat set
position station and operator on the platform stop the operation before the
davit rear span and the boat come into contact using the control lever lower
the lifeboat until it is positioned on the roller raise and lower the lifeboat
several times with the control lever thus adjusting the stowed position until
it is possible to attach the main lashing each operation should be
implemented slowly and in concert with the signals provided by the operator
stationed on the platform securely attached the main lashing to the release
hook after confirming that the main lashing is secured the crew may
disembark the lifeboat via the rear hatch the operator on deck lowers the
suspensions detaches the wire ropes for hanging the boat and attaches them to
the plate provided using the control lever move the davit arms to the stowing
position although the davit arm stops moving when it comes into contact with
the arm support keep an eye on the davit arm during this operation attach the
hook lashing lines to the suspensions
set the lashing line the lashing plate is set automatically once the lashing
lines are attached turn off the power pack
the sonís convention requires that full vessels equipped with freefall lifeboats
also carry rescue boats
you
let's take a look at rescue boat davits launching operations using the davit can
be performed both inside the rescue boat and on deck
it is mainly composed of a post stand davit arm a release hook hydraulic power
pack and a winch
carrying a freefall lifeboat rescue boat davits can also be used as life raft
davits the winch unit is composed of a wire drum electric motor speed reduction
device handbrake device and a governor brake device lowering and launching of
the lifeboat is possible by operating the slowing remote control wire the
inboard remote control wire deck remote control wire and the hand brake device
which allows the lifeboat to descend at a fixed speed under its own weight
boats automatic release work is composed mainly of a hook a hook reset lever a
release lever an automatic release wire and an on load release wire
when lowering and launching a rescue boat begin by switching on the power
pack open the accumulator valve and confirm that the davits looing area is
free of obstacles confirm that the slowing remote control wire and the
inboard remote control wire have been drawn into the boat confirm
the boat hanging wire is attached to the release hook and that the painter is set
to the painter releasing device which is located at the bow of the rescue boat
remove the lashing wire rope remove the safety pin from the handbrake device on
the winch board the crew the operator on deck uses the hoisting switch to raise
the boat free of its stand
during hoisting swing-out launching and release of the rescue boat the operator
on deck shall stabilize the boat using the painter the crew on board the rescue
boat pull the slowing remote control wire and slew the dammit to the lowering
position slowing stops when the operators hand is removed from the
slowing remote control wire prior to slowing and lowering of the rescue boat
ensure that the tracing line has not become entangled with the boat if the
power supply is cut off pressure stored in the accumulator can be used to
complete the operation however if the amount of stored pressure is
insufficient slew the davit manually with the hand pump when the crew pulls
the inboard remote-control wire the winch break is released and the boat
begins to descend
tact with the surface of the sea the automatic release wire should be pulled
to release the rescue boat after starting the engine release the painter
releasing device and proceed with the rescue
the operator can also lower the boat by pulling the deck remote-control wire or
lifting the brake lever on deck
in the case of automatic release pull the automatic release wire to bring it
into the set position for automatic release mode prior to making contact
with the surface of the sea as long as the hook is bearing a load it will not
open once the boat is waterborne the hook will release automatically for the
sake of safety pull the release wire after the boat is water borne if the
automatic release hook does not function after making contact with the sea pull
the unload release wire and release the hook as in the case of automatic release
operations unload release is carried out by pulling the automatic release wire
into the set position for automatic release mode pulling the unload release
wire and releasing the hook insert the safety pin and lock the winch handbrake
device attach the shackle of the boat hanging wire to the hook in the released
position pull down the hook reset lever to reset the release lever will be reset
automatically in the locked position
hoisting switch to raise the boat
visually observe the operation until hoisting is stopped automatically by the
limit switch
the operator should confirm that the boat slowing area is free of obstacles
and then slew the davit to the stowed position set the boat on the stand and
set the boats gnashing line check the powerpack pressure gauge and if
necessary recharge it to the specified pressure
level when the operation has been completed close the accumulator valve
for recovery of a rescue boat in bad weather use the recovery strap when
launching a rescue pose in bad weather mount the recovery strap to the joint
plate in advance also prepare the hanging off pendant
launched the rescue boat by following the standard rescue boat launching
procedures remember do not use the recovery strap for launching operations
when oystering the rescue boat attached the recovery strap to the boat link
heist the boat to a position where the hanging off pendant can be set and then
set the hanging off pendant slew the davit into a position where the boat can
be pulled toward the ship and have the crew embarked on the ship lower the boat
until its full weight is borne by the hanging off pendant and remove the
recovery strap set the release hook to the boat link voice the boat until its
full weight is borne by the release hook and remove the hanging off pendant slew
the Davitt and store the boat
you
they are normally folded and are kept stored in an FRP contain life rafts
carried on tankers are oil proof that flame grip that some have a structure
that prevents the accumulation of static electricity
life raft accessories include canopy light room lamp seawater battery lithium
battery safety valve for chamber
inflation gear c-anca retroreflecting tape and boarding ramp these items have
specific applications for specific contingencies some are to be used at an
early stage during launching and initial drifting some are employed to maintain
the crews physical strength while adrift
while others are used to maintain the life rafts performance still others are
for transmitting distress signals all life
conforming with so last 96 have instructions stickers on the surfaces of
their containers one of the most commonly used life rafts it's the
dropping type which is stowed on deck
the life raft container is placed on a cradle and is secured by a lashing wire
with an automatic release device life rafts conforming to Solace 96 are of the
weak link type and the painter is attached to the painter connecting ring
an automatic wire and an operating wire are located at the painters midpoint the
operating wire is connected to the painter inside the container some older
types of life raft have a separate automatic wire or wires and painters and
do not have a weak link manual dropping of a life raft is possible by pulling
the release handle built into the cradle
the automatic release device has an automatic operating mechanism that is
triggered by water pressure it cannot be operated manually some older types of
life raft feature an automatic release device with a manual dropping handle a
cradle with a weak link has one end of the weak link connected to the cradle
and the other end either to the painter connecting ring or directly to the
painter
when a ship sinks tension is applied to the weak link and the link disconnects
separating the life raft from the ship
in an emergency situation it is possible to manually initiate a gravity fall of
the container along the inclined cradle in this case the operating wire is
pulled and the inflation of the life raft is triggered opening the container
and allowing the life raft to inflate automatically some units allow inflation
and discharge of the life raft by pulling the painter manually after
dropping the life raft container when the life raft is dropped manually the
ship and the life raft are moored to the painter and no tension is applied to the
weak link as such it is necessary to cut the painter after embarkation should the
ship sink before the life raft can be dropped manually hydraulic release
equipment will be activated at a water depth of between two and four meters the
containers buoyancy causes the automatic wire to be pulled inflating and
discharging the life raft at the time of inflation the painter is disconnected
from the ship upon activation of the hydraulic release equipment the weak
link is broken after the life raft is inflated
the painter and one end of the week link are directly connected to the painter
connecting ring on the hydraulic release equipment while the other end of the
weak link is secured to the ship
the operating wire is connected to the painter inside the container the painter
is directly connected to the painter connecting ring on the hydraulic release
equipment and the weak link connected and the midpoint on the painter is
secured to the cradle the operating wire is connected to the automatic wire
inside the container the painter is directly connected to the painter
connecting ring of the hydronic release equipment the automatic wire is also
directly but independently connected to the cradle all of the following must be
checked prior to drop launch of the lighthouse confirm that the liferaft
container is not lashed with a rope or other bond
check that there is no feet obstructing the cradles auxiliary rail rotating pin
ensure that the pacer is connected to the hydraulic release equipment
check and confirm the connection of the weekly make sure that the safety pin is
attached to the cradles release her when boarding the life raft from the ship use
a ladder or boarding ramp when climbing the board from the water use the
boarding ramp or a letter attached to the raft it is also possible to jump
from a height of not more than 4.5 meters onto the canopy pay attention to
crew already in the raft do not board with tools cutlery or other objects that
could damage the life raft if the life raft should inflate in an inverted
position climb on the co2 gans cylinder while taking hold of the writing rein on
the bottom and apply your weight to turn it over to its normal position one
person can write the life raft this operation is much easier if natural
forces wind and waves are used after boarding the raft is completed remove
the knife kept outside the canopy and cut the painter in such a way as to
leave about five meters of it attached to the life raft after separating the
painter recover the sea anchor that is tied near the external co2 cylinder to
avoid being caught in the whirlpool caused by sinking of the parent ship
remove the pedals from the accessory bag stick them out of the two openings in
the boarding ramps and row the raft according to instructions provided
maintain sufficient distance from the ship to avoid being caught in the
whirlpool only now should the sea anchor be redeployed as an auxiliary pitcher it
is possible to move the life raft by dropping the sea anchor into the water
and then pulling the life raft towards it
the initial procedures after boarding the life raft are described in the
manual instructions for immediate action and it is strongly advised that these
directions are followed
if the container is connected to the life raft and is floating use a knife to
sever the connection
retroreflecting tape which makes a search for both sea and air easier is
attached to the surface of the lifer
in addition to this Griffin signals
radar reflector dye marker to be used during daytime etc all of which can be
found in the accessories panic now let's see how to watch a life of using the
davits launching living under the dabit launching method the container of the
life raft is lifted by the David and the davits is turned to the life raft
lowering position by pulling the automatic wire the life raft inflates
and the crew embarked while the life raft is suspended above the deck using
the dabit the life raft is then lowered splashes down and is released the
biggest advantage of the davit launching method is that it makes it possible for
the crew to evacuate the parent ship without getting wet
in normal situations the life raft container is stored on the deck cradle
the davit assisted launch procedure for a life raft is the same as that for a
rescue boat lowering and launching a possible with the operation of a winch
remote control
ships are often equipped with supplementary carry and drop type life
rafts when standard lifeboats on life rafts are installed at distances from
the bow or the stern of more than 100 meters automatic release devices are not
required for carrying drops like life rounds some carry and drop type life
rafts are equipped with an automatic release device but they are used in the
same manner as life rafts without an automatic release device the life raft
is carried to the dropping position where the painter is secured to the ship
and the life raft is dropped when the life raft is installed on a cradle with
an automatic release device set the painter and the automatic wire so that
they do not hinder automatic flotation it is essential that they are set
according to the manual provided by the manufacturers
now let's look at accessories my folks and my friends the accessories Archer
you
see dye marker special accessories for life bonus pockets
you
extinguishing special accessories for life rounds paddles safety scissors
sponges optional accessory desalinator
the satellite epub is activated when it is removed from the installed position
in the parent ship and transmission starts automatically the name and
position of the vessel in distress etc are sent to the earth stations via
satellite should the ship sink the ePub floats by itself and automatically
begins transmission the Sat radio transponder is used for search and
rescue of survivors via GM DSS global maritime distress and safety system it
receives transmissions from radar units installed on search and rescue boats
aircraft etc and transmits response signals visual signals are used as
distress signals for verses the flash and a large amount of orange colored
smoke help identify the position the vessel
you
self-activating smoke signals are used either as distress signals with the
parent ship or in order to indicate the position of a lifebuoy to a person
overboard they are tied to the lifebuoy when used once thrown into the sea they
self activate and continuously produce smoke for 15 minutes or more buoyant
smoke signals are designed for daylight signaling purposes on lifeboats and life
rafts and they continuously produce smoke for 3 minutes or more the ignition
is manual and the performance is almost identical to self activating smoke
signals self-igniting lights are signals that automatically ignite when thrown
into water they continuously produce white light or flashes of two containers
for at least two hours like self activating smoke signals they are tied
to a lifebuoy when used rocket parachute signals are launched by rockets to a
height of over 300 meters they descend with a parachute while producing a red
flare of about 30,000 candelas for 40 seconds or more rocket star signals are
launched by rockets to a height not less than 150 meters producing red stars of
about 250 candelas for 3 seconds or more
remove the caps on the top and bottom
remove the safety pin then lift the ignition lever to launch while holding
the body of the signal vertically press the ignition lever in the rocket body
with your palm hand flares indicate the position of lifeboats and life rafts a
red colored flare of about 15,000 candelas is continuously produced for at
least one minute to ignite a hand flare lift the grip and pull out the ignition
cap after ignition starts hold it as far away from your body as possible keeping
it on the leeward side the floating body of a lifebuoy is made mainly of cork
those used for rapid release gear wait for kilograms or more and those for
other devices weigh approximately two point five kilograms lines
appliances are capable of launching a line and reaching a distance of over 230
meters toward the distressed vessel a set comprises one rocket type launcher
four or more projectiles and aligned longer than 320 meters
remove the front covers on the top and bottom remove the wire cord attached to
each projectile connect the end of the rope at the back of the case to the ship
structure handrail etc
remove the safety pin and pull the trigger
following the amendment to the SOLAS convention in July 2006 all cargo
vessels at 500 gross tonnage and war shall be equipped with immersion suits
in numbers sufficient for all persons on Jordan emotion suits come in two types
those with inherent insulation and those with non inherent insulation inherent
insulation type suits which exhibit high insulating performance allow the wearer
to survive for six hours in water as cold as two degrees Celsius normal
inherent insulation suits are now the wearer to survive for one hour in water
no colder than five degrees Celsius
immersion suits are dry suits that cover the whole body with the exception of the
face both inherent and non inherent insulation suits are worn over clothing
and it is required that they can be unpacked and donned without assistance
within two minutes
when donning an immersion suit put your legs into the suit and then pull the
suit up to cover the whole body including the fingers finally cover your
head
there are both buoyant and non buoyant immersion suits use a lifejacket in
conjunction with non buoyant immersion suits for the anti exposure suit
priority is given to improved user movability
and operability as a trade-off the materials used are less waterproof and
less capable of retaining body heat it is possible to survive for one hour in
water of five degrees Celsius it is required that life jackets can be done
without assistance within one minute and they must also meet requirements for
buoyancy and strength they are designed to resist damage and it is required that
they will not be torn from the users body even if the user jumps from height
of 4.5 meters they will not injure the user either two types of lifejacket are
available rigid type and inflatable type
rigid type lifejackets have a buoyant structure after donning a rigid type
lifejacket the user secures it to the body with a cord or a buckle
inflatable type lifejackets have two independent compartments that are
inflated either manually or automatically
should inflation be insufficient use the auxiliary air supply device which can be
inflated by mouth lifejacket lights come with the lifejacket and can be turned on
manually they remain lit for eight hours or longer
according to revised soleus from 2010 all lifejackets used on newly built
vessels should be equipped with a buddy line to allow survivors to link
themselves together and a lifting loop
bandage type lifejackets will no longer be approved
this section deals with inspection and maintenance life-saving appliances to be
carried out by the crew onboard the ship
as from July 2006 annual inspections servicing and repair of lifeboats shall
be conducted by the manufacturers representative for a person
appropriately trained and certified by the manufacturer
however it is the responsibility of the crew on board to perform maintenance and
inspection of life-saving appliances on the ship in order to ensure reliability
equipment and to maintain effective operation the crew shall carry out
weekly and monthly inspections in accordance with the instructions for
maintenance and inspection provided by manufacturers visual and operational
inspections are required for the maintenance and inspection of lifeboats
external visual checks should look for obvious damage scratches cracks
deformations and other abnormalities and confirm that devices such as the release
gear are properly reset operational inspections shall be carried out for the
release gear paint a releasing device steering system and rudder propeller and
so on it is also necessary to check that there is no water leakage from the
steering gear and the stern tube
you
and the all wines have been wound corrected and supplied prices for fire
protected life bonus should be checked for corrosion off or leakage from
