  1. Question 1

    A prime cause of early failure of hatch seals is over-compression caused by corrosion or breakdown of the steel-to-steel contact. Cleats are then frequently over-tightened in an attempt to compensate. But what types of failure does this action commonly result in? Select all applicable answers:
    • Accelerated wear on the seal.
    • Fracture of the cleat assembly.
    • Misalignment of the hatch cover.
    • Possible structural collapse at the hatch corners.
    • Distortion of the roller wheels.

  2. Question 2

    You have just replaced the seal on number 2 hatch. What should you do now?
    • Measure the seal compression and record it.
    • Secure the lid as tightly as possible and leave it closed until arrival; in the next port.
    • Measure the groove in the seal in the forward corners of the hatch.
    • Compare the appearance of the new seal to that of the old seal.

  3. Question 3

    After defective seals, what is one of the largest causes of serious cargo damage resulting from ingress of water, as highlighted in this module?
    • Blockage of the drain channels, non-return valves or socks by cargo residues.
    • Distorted cargo hatches.
    • Heavy weather.
    • Blocked bilges.

  4. Question 4

    Article III, rule 1 of the Hague-Visby Rules requires the carrier to fulfil which of the following conditions? Select all applicable answers:
    • Make the ship seaworthy.
    • Properly man, equip and supply the ship.
    • Make the holds, refrigerating and cool chambers, and all other parts of the ship in which goods are carried, fit and safe for their reception, carriage and preservation.
    • Man, equip and supply the ship to minimum cost.
    • Make the holds, tanks, refrigerating compartments and other spaces generally clean and fit for the carriage of goods that are not designated for human consumption.

  5. Question 5

    As quoted in this chapter, which of the features listed below, render all hatch covers potentially dangerous? Select all applicable answers:
    • They move quite quickly, very often with no audible or visible alarms to give warning of their movement.
    • They are manoeuvred by heavily-loaded wire arrangements, hydraulic cylinders or chains and often make use of gravity, particularly when closing.
    • They are generally slow moving, which makes their movement difficult to detect.
    • They are controlled by wires and chains, which could part at any time if the weight of the hatch comes on them unexpectedly.
