  1. Question 1

    A seal is found to be damaged on a panel, allowing water into the mechanism of a crane fitted on the bow. What should NOT be done?
    • Remove the water and dry the chamber.
    • Leave the panel loose, so that it may be checked more frequently.
    • Replace the seal and refit the panel.
    • Treat and re-coat any area of rusty steel.

  2. Question 2

    A ship is taking stores, using a provisions gantry crane and cargo net, lifting approximately ten loads, some palletised, from a barge alongside into the stores flat behind the accommodation. How should the loads be controlled and why?
    • The loads should be brought on board as quickly as possible, in order to save paying overtime for the delivery barge. It is up to the cooks and stewards to clear the loads as quickly as they can.
    • The loads should be reduced in size and number of boxes and packages to that which can be handled by the cook and stewards without any overlap or delay. The rate of loading should be such that they just have enough time to clear one load before the next arrives.
    • Due time should be allowed to unload one net and clear the handling area before the next lift is brought on board. This is to avoid anyone working under a suspended load.

  3. Question 3

    Can a crane be used to “drag” a heavy load closer and make the lift easier?
    • No.
    • Yes.

  4. Question 4

    Crew are lifting hoses and reducers using the deck manifold cranes. What must happen if a pilot is to soon board by helicopter? Select the THREE correct answers.
    • All associated loose gear must be secured.
    • The crane must be housed.
    • The Responsible Officer must verify these facts and indicate he has done so by ticking the relevant box on the pre-helicopter operations checklist.
    • Crew must continue lowering hoses into position, so that the ship is ready for work when it gets alongside.

  5. Question 5

    How might low temperature and ice beginning to form, affect the operation of the manifold crane? Select the TWO correct answers.
    • The control station, access ladder and work area can become slippery and dangerous.
    • The hydraulic oil temperature might initially be below the minimum operating temperature.
    • They will not affect the operation at all.
