SHIPS, SHIP ROUTINES AND SHIP CONSTRUCTION (FINALS) Flashcards
are used to close off the hatch opening and make it watertight.
Hatch covers
consisting of beams and boards over the opening and covered with tarpaulins, were once used but are no longer fitted
Wooden hatch covers,
comprising a number of linked steel covers, are now fitted universally.
Steel hatch covers,
Hatch covers are used to close off the hatch opening and make it
watertight.
The means of securing the hatches and maintaining their watertightness is tested initially and at
periodic surveys.
The means of securing the hatches and maintaining their _ is tested initially and at periodic surveys.
watertightness
These patent covers vary in type the principal ones being _
fore and aft single pull, folding, piggy back, pontoon and side rolling.
provide at the exposed deck access to the tank spaces.
hatchways
The openings for these are kept as small as possible, and the corners are well rounded, circular openings being not uncommon.
hatchways
are used to secure the mooring lines
Bollards
should penetrate the baseplate rather than just be welded to the top of the baseplate, and strengthening rib plates should be fitted in the base
bitts
a non-roller type fairlead mounted at the ship’s side and enclosed so that mooring lines may be led to shore with equal facility either above or below the horizontal
Panama fairleads
Usually operating in a horizontal plane. Its function is to change the direction of lead of a mooring or of other line on a deck
pedestal
Vertical tubular steel posts; two of them are fastened to the rectangular base of a bollard
multi angle
A rectangular base welded to the deck of the ship, upon which two vertical bitts are welded.
roller
– Winches designed to heave-in automatically whenever the line tension falls below a certain pre-set value
tension mooring winch, self-tension winch
The use of the self-tension winches is not recommended except for mooring deployed at _ to the ship axis
90°
incorporates an arrangement to facilitate drainage, with the chain cable stowed on a grating.
Chain locker
is secured to the side or top structure of the chain locker by an arrangement that incorporates means for emergency release.
The chain end (bitter end)
step-by-step method recommended for securing the anchors after they are hove up tight
a) Ensure that the windlass brake is tightly secured. The bow stopper is placed in position and the windlass.b) Reave the anchor lashing steel wire rope through one of the chain links or alternatively place the devil’s claw on the cable.c) If the wire is used connect bottle screw and screw the bottle screw up tightly.d) Put the hawse pipe and spurting pipe steel plate covers in position.e) Cover these plates with a canvas cloth.f) The spurting pipe must be additionally coated with a good protective coat.
usually consists of parallel vertical plates mounted on a base with a pivoting bar or pawl which drops down to bear on a chain link
CABLE STOPPER
is arranged to ensure that water can be drawn from any tank or the sea and discharged to any other tank or the sea as required to trim the vessel.
ballast system
consisting of sea inlet(s), suction piping, fire pumps and a distributed piping system supplying fire hydrants, hoses and nozzles located throughout the vessel.
fire main is a system
Its purpose is to provide a readily available source of water to any point throughout the vessel which can be used to combat a fire and is considered the backbone of the fire-fighting systems onboard a vessel
fire main is a system
is provided with a reliable and versatile system capable of providing a number of different methods with which to engage a fire
firefighter
can be supplied as a straight stream for combating deep seated fires, as a spray for combating combustible liquid fires where cooling and minimum agitation is desired or as a means to protect personnel where cooling is the primary effect desired
Water
The _ value of the tank is the total quantity of fluid (oil, bilge, sludge, or water) inside a ship’s tank
final sounding
is considered as part of sounding process on ship
Checking the level of the fluid in a tank
are put down cell guides and landed one on top of the other
containers
An approved _ will be available on board, which must be followed to ensure correct lashing and securing of the cargo
Cargo Securing Manual (CSM)
must be referred to keep a proper check on the height check of the stack to avoid any damages to the containers while pontoon securing.
Cargo Securing Manual
It is quite often missed out when the stowage plan is issued by the planner
Cargo Securing Manual
It is a machine that is used on cargo of the ship “a tower built which is used to raise and lower the drill”.
Derrick
In order to minimize the risk of corrosion, internal surfaces are provided with
- protective coating
In COSWP hand signals for crane operation, placing one hand in front of the body with thumb pointing upward and others closed, flex finger in and out as long as movement desired?
- raise the boom and lower the load
It prevents the single boom from swinging side to side while loading or discharging
side line/side guy
A form of hatch cover which the panel is moved one by one and placed on top of one another
piggy back hatch cover
Special form of winch used to hoist the anchors, house them safely and warp the ship in harbor
- windlass
What method is used to test the water tightness?
hydro test
A portable ladder hinged to a platform attached to the side of the ship and can be positioned to provide access between ship and shore
- accommodation ladder
At the booming section, through the side ends which keeps the hatches water tight
- gasket
Anchors are prevented running out and secured by
all of the above (pawl, devil’s brake, brake)
