Segregation of cargoes refers to
Separating cargoes so that the inherent characteristics of one cannot damage the other
Keeping certain cargoes separated because of their inherent characteristics I known as
Segregation
Damage to cargoes causes by fumes or vapors from liquids, gases, or solids is known as
Tainting
Certain cargoes must be separated because of their
Inherent characteristics
Which is an example of cargo damage caused by inherent vice?
Heating of grain
A spreader bar is used to
Protect the upper part of a load
The best way to lift many small articles aboard your vessel is with a
Pallet
A sling is a device used in
Hoisting cargo aboard a vessel
When a two- leg sling is used to lift a load, a sling of 40 feet long is better than of 30 feet because the
Tension in the sling legs is less
Manila lines should not be used to load
Steel

5 years
In relation to cargo gear, what dues SWL mean?
Safe working load
A periodic thorough examination of the cargo gear proves satisfactory. What percentage of the total gear must be dismantled to determine actual internal condition?
None
All wire rope used in shipboard cargo gear must be identified and described in a certificate. The certificate shall certify all of the following…
And will NOT show…
Date of the test
Load at which a test sample broke
Number of strands and of wires in each strand
WILL NOT SHOW name of vessel
The wire rope uses for cargo handling on board your vessel has a safe working load of 8 tons. It shall be able to withstand a breaking test load of (46 CFR 91.37-35(a))
40 tons
The safe working load for the assembled cargo gear and the minimum angle to the horizontal for which the gear is designed shall be marked on the
Heel of the boom
What is required to be stenciled at the heel of a cargo boom ?
Safe working load
The term “standing rigging” refers to
Stays and shrouds
Backstays are
Standing rigging leading AFT from the masts
A shroud is
A heavy wire extending from the mast, athwartships to the deck, to support the mast
The head block is located
At the head of the boom
The heel block is located
At the base of the boom
The band or collar on the top end of a boom to which the topping lift, midships guy, and outboard guys are secured, is called the
Spider band
Which part of the cargo boom has the greatest diameter?
Middle
The fitting that allows the boom to move freely, both vertically and laterally is called the
Gooseneck
What is meant by “spotting the boom”?
Placing it in the desired position
The process of lowering a boom to a horizontal position and onto it’s deck support is called
Cradling a boom
In a Burton rig, the dock boomcan also be called the
Yard boom
With a given load on the cargo hook, the thrust on a cargo boom
Increases as the angle of the horizontal increases
The greatest horizontal stress between The heads of the booms in a yard and stay rig occurs when the load is in such a position that the
Falls are at an equal angle to the horizontal
You are lifting a one-tone weight with a swinging boom. When comparing the stress on the rig with the boom at 20 degrees to the horizontal to the stresses when the boom is at 60 degrees to the horizontal, which statement is TRUE?
The thrust on the boom is greater at 60 degrees
For a given weight of cargo, the stress on the heel block of a cargo boom
Decreases as the boom is topped to a greater angle
You are lifting a one-tone weight with a swinging boom. When comparing the stress on the rig with the boom at 20 degrees to the horizontal to the stresses when the boom is at 60 degrees to the horizontal, which statement is TRUE?
The stress on the head block is greater at 60 degrees
You are lifting a one-tone weight with a swinging boom. When comparing the stress on the rig with the boom at 20 degrees to the horizontal to the stresses when the boom is at 60 degrees to the horizontal, which statement is TRUE?
The stress on the HEEL BLOCK is LESS at 60 degrees
You are lifting a one-tone weight with a swinging boom. When comparing the stress on the rig with the boom at 20 degrees to the horizontal to the stresses when the boom is at 60 degrees to the horizontal, which statement is TRUE?
The stress on the MASTHEAD FAIRLEAD for the topping lift GREATER at 20 DEGREES.
Which provides for transverse control and positioning of a boom in a conventional yard and stay system?
Guy
When cargo is being worked using a Burton or married fall system, which part of the cargo gear is most likely to fail?
Guy tackle
When handling cargo, the majority of the cargo gear breakdowns is due to
Guy failures
When viewed from above, the best position for the guy in relation to the boom is
At right angle
The maximum theoretical stress that can be developed on a guy in a yard and stay rig is limited by the
Lifting capacity of the winch
In a married falls rig at the after end of a hatch, a boom is rigged in a fore and aft line through it’s heel. Stresses on the outboard guy will be LEAST if the guy is made fast at a point
At right angles to the boom when viewed from above
Illustration D004DG You are rigging up a married fall system and are spotting the hatch boom. You decide to spot the boom over mid-hatch, approximately 4 feet inside the hatch coaming. Where should the outboard guy be positioned?
B
On cargo booms, preventers are
Auxiliary guys
A preventer guy
Is a safety measure in case one of the outboard guys parts
The purpose of a preventer as it is used on a conventional yard and stay cargo rig is to
Assist the outboard guy in supporting stresses during cargo handling
The safest procedure used to rig a guy and preventer is to have a guy
Under slightly more tension than the preventer
When rigging a guy and preventer properly, the guy should be
Slightly more taught than the preventer
If the cargo gear on your vessel is equipped with a regular guy and a preventer guy, you should
Secure them as close together as possible on deck
The preventer guy, as used on a conventional yard and stay rig, should
Take the strain if the regular guy parts
A tackle by which the outer end of the boom is raised and lowered is the topping
Lift
What would you use to adjust the height of a cargo boom ?
Topping lift
You would find a topping lift
On a yard and stay rig
Which part of a conventional cargo gear rig provides for vertical control and positioning of a boom?
Topping lift
A single heavy wire made up for the topping lift is called a
Bale
A flounder plate, on a topping lift, is
A triangular steel plate with a hole at each corner
Stress on the topping lift of a swinging boom can be reduced by
Raisin the boom
With a given load on the cargo hook, tension in a single span topping lift
Increases as the booms angle to the horizon decreases
What is meant by “topping the boom”?
Raising the boom
The cargo fall over the dock is called the
Burton fall
When snaking cargo into the wing of a hold with the cargo winch, the runner should lead from the
Heel block to a snatch block
What is the minimum standard for making an eye splice in a wire to be used as cargo gear
Make three tucks with full strands, remove half the wires from each strand, and make two more tucks
It is permissible to place an eye splice in wire rope used as cargo gear provided the splice is made using
Three tucks with whole strands and two tucks with 1/2 the wire cut from the tucking strand
Which end is NOT acceptable in a wire rope that is free to rotate Wheb hoisting?
Liverpool eye splice
Which ending IS acceptable in a wire rope that is free to rotate when hoisting ?
Poured socket
Eye formed with pressure clamped sleeve
Eye formed by clips
A force acting on a single cargo runner which is vertically lofting or lowering a load I greatest when
Decelerating when lowering the load
Of an electric cargo winch is used to lift a draft of cargo and the engine room loses all power, which will occur?
An electromagnetic brake will hold the load where it is suspended
Which device is designed to automatically hold the load if power should fail to an electric winch?
Electromagnetic brake
Electric cargo winches have an overload safety device which normally cuts the current to the winch motor
After torque causes line pull to exceed the rated capacity of the winch
If an attempt is made to hoist a load that exceeds the capacity of an electric winch, and overload safety device causes a circuit breaker to cut off the current to the winch motor
After the line pull exceeds the rated winch capacity
If a hydraulic pump on a winch accidentally stops while hoisting, the load will stay suspended because
A check valve will close and prevent reverse circulation
When a winch breaks down, or some similar occurrence makes only one winch available at a hatch, which alternate rig would provide a temporary solution while the repairs are made?
Yard and stay Jury Rig
