Describe the process of securing a vessel to a berth using mooring lines.
The process involves approaching the berth, deploying mooring lines to bollards or cleats, and ensuring proper tension and secure fastening.
What documentation is required for mooring equipment maintenance and inspections?
Maintenance logs, inspection reports, and records of any repairs or replacements.
How often should mooring equipment be inspected, and what should be checked during an inspection?
Mooring equipment should be inspected regularly, at least once a month. Inspections should check for wear, corrosion, and proper functioning of winches and bollards.
How should synthetic mooring ropes be maintained compared to wire ropes?
Synthetic ropes require regular cleaning, inspection for UV damage, and proper storage. Wire ropes need lubrication and checks for corrosion and wear.

Non weighted
Made from polypropylene rope (or similar)
If weighted, not more than 0.5kg of pea
Inform receiver prior to throw

What is the role of a winch in mooring operations, and how should it be operated safely?
A winch is used to apply tension to mooring lines. It should be operated by trained personnel, with regular checks on brake linings and tension control systems.
What are the common practices when rigging a gangway / accommodation ladder?
Away from cargo / lifting operations
No obstructions on quayside -> bollards, manifolds
Rigged properly subject to risk assessment
Gangway net

- With shelter and communication
Must be certified
What are the latest SOLAS amendments related to mooring equipment?
The latest amendments require ships to have management plans for the inspection and maintenance of mooring equipment and to ensure equipment is designed to withstand undue strains.
Explain how safe access can be maintained on vessels?
Designated safe walk ways
Illumination
Handrails
Hazards (slips / trips) marked clearly
Pipes marked clearly
Cable tidies for hoses
Remove trip hazards -> place cables etc above heads
Slip resistant grit applied
Scuppers and drains clear
Good housekeeping
Remove cargo debris
Remove snow and ice accumulations
Avoid cargo / crane operations over walkways
Find alternatives
Cargo hatches and openings barrier off with rails 1metre high
What are the main types of mooring lines used on ships, and what are their characteristics?
The main types are nylon, polyester, and wire ropes. Nylon is elastic and absorbs shock, polyester is stronger and less elastic, and wire ropes are very strong but less elastic.
What are the duties of the OOW when mooring?
Supervise operation
Aware of mooring plan from Master
Review risk assessment
Check area is suitable -> illumination, obstacles
Check equipment works and in good condition -> winches, windlass, capstans, fairleads and ropes
Monitor for correct handling of ropes
Snap back zones
Provide communication to Bridge
Provide information regarding obstructions to accommodation ladder / gangway

What are the potential hazards associated with mooring operations, and how can they be mitigated?
Hazards include rope snapback, slipping, and equipment failure. Mitigation involves proper training, use of PPE, and adherence to safety procedures.
What is good practice when using stoppers?
Stoppers must be same material as rope
Use double cross over type -> west country style
Ensure stoppers long enough for long tail hold
Never go to fast
How should mooring lines be stored to ensure their longevity?
Store them in a dry, well-ventilated area, away from direct sunlight, and cover them with tarpaulins if kept on deck.
What is the purpose of gangway nets / safety nets?
Mounted where persons can fall
Or objects
Explain the importance of proper maintenance of mooring winches.
Proper maintenance ensures the winches operate smoothly, prevents accidents, and extends the equipment's lifespan.

Cold dry air moves over warm sea surface
Evaporates from surface of water
Air is unable to contain water vapour so immediately condenses.

Position when anchor let go
By observing the anchor cable if she comes to long stay then short stay and then long stay repeatedly means she is dragging anchor.
