Which ONE of the options best completes the following statement? ‘A synthetic fibre tail attached to a mooring wire …

… introduces a weak link, because the fibre is not as strong as wire’.

… makes the wire easy to handle and helps absorb sudden loads’.

… can be far too elastic, allowing the vessel to surge on the berth’.

… is bad practice and not used on large vessels’.

Which ONE of the options best completes the following statement? ‘A wire mooring rope that has been heaved around a tight corner under load …

… will not suffer any damage’.

… will be safe to use in the future’.

… will not endanger the safety of the crew.

… will get a permanent kink in it’.

Which ONE of the options best completes the following statement? ‘Slipping a synthetic fibre mooring rope on a drum end …

… should be avoided, because it damages the rope’.

… should be done if excessive strain comes on the rope’.

… should be done by experienced seamen only’.

… should be done with only three turns on the drum end’.

Which ONE of the options best completes the following statement? ‘Synthetic fibre mooring ropes …

… should be hung in the boiler room to dry when not in use’.

… should be stored in direct contact with the deck’.

… should be stowed in a safe area when not in use’.

… should never be washed with fresh water’.

Which ONE of the options best completes the following statement? ‘When spooling a new mooring wire on a fixed drum …

… start with the end of the wire found inside the coil’.

… place the coil on deck, just in front of the drum’.

… clamp one end, then drop the coil overboard to unravel it’.

… suspend the coil on a turntable or roller to stop kinks’.

Which ONE of these options best completes the following statement? Inspection records for mooring ropes should be maintained on-board because …

… the flag State require this to be done on all vessels.

… everyone on-board, and any inspectors, can see that the ropes have been inspected and are fit for purpose.

… there is an OCIMF regulation stating this practice is to be followed on board all tankers.

… the ISM code requires it to be followed on all vessels.

Which ONE of these options correctly completes the following statement? ‘Six strand, ‘wire laid’ synthetic fibremooring ropes …

… are never used for mooring ropes’.

… are particularly suited to use on self-tensioning winches’.

… are not suited to use on fixed mooring drums and winches’.

Which of the options correctly describe the easiest way to identify a mooring rope? Select the ONE correct answer.

By its colour.

From the tag, if fitted.

From the stored certificate.

By its position on the vessel.

Which of the options correctly describes ’actinic action’ seen on a mooring rope? Select the ONE correct answer.

It occurs when acid has attacked the fibres of a mooring rope.

It is when UV radiation changes the chemical nature of the rope fibre.

It is a technical description for a mooring rope stretching.

It is the action of the rope when it parts with excessive strain.

Which of the options correctly describes the typical construction of a wire mooring rope? Select the ONE best answer.

6 × 36 or 6 × 41.

Only ever 6 × 41 and a fibre core.

6 × 24 or 6 × 36.

Only ever 6 × 36 and a wire core.

The wire should be strong, but stretch easily.

The wire should have a small diameter to make for easy handling.

The wire should be strong, easy to handle and with low stretch.

The wire should be strong, with absolutely no stretch at all.

Which one of these options best describes why mooring ropes have chafing mats and sleeves fitted to them? Select the ONE best answer.

It is mandatory to do so.

To increase the strength of the rope.

To protect the rope from being chafed.

To protect the fairlead through which the ropes pass.

Which one of these options correctly describes the characteristics of polyester rope? Select the ONE correct answer.
