When a ship is taken into any place to load /unload the cargo, the operation involving tying of ship to any fixed point using mooring ropes and cables so that it can be hold firmly at a place is called as ‘Mooring Operation’.
Ships can be moored in different ways :-
- Mooring at jetty (eg. any terminals on land in ports bulk terminals, passengers terminals, tankers terminals)
- SBM (Single Buoy Mooring ) ,which is also is called as onshore terminal, in which ships like tankers can be Moored.
What is purpose of mooring?
- For efficient and reliable transportation of cargo and for prevention of accidents of ships like grounding, collision with vessels in vicinity and oil spillage, etc.
- When a ship is at port or loading terminal it is necessary to properly secure ship to any fixed remedy ,so that it will prevent the ship from drifting because of currents, tides ,winds and turbulence created by movements of ships in vicinity.
- A vessel can be hold at one place with help heavy ropes and hawsers of different material and characteristics, which prevents the forward-after, athwartships movements of ships, when she is at berth.
- These hawsers or ropes are also called as ‘Mooring Lines’ and its types are ;-
- Natural fibre Ropes
- Synthetic fibre Ropes
- Steel wire Ropes.
What is Mooring Buoy ?
Mooring Buoy is floating offshore terminal which connects underwater pipeline onto refineries on the land. A Tanker vessel can be moored to this mooring buoy for loading/unloading of cargo . In this operation ,there are 3 teams involved:-
- Ships personnel involved in tanker operation
- Loading Master at SBM(single buoy mooring)
- Shoreside crew (eg. at refineries)
SBM moors a tanker at single point and weathervane about that point. It is anchored to seabed and connected with subsea pipelines through subsea hoses.
How to tie up to a mooring buoy?
Pre-tanker berthing checks:-
- Inspections of mooring hawser for any visible damage and ensure sound health
- Inspection of floating hoses for any damage,loose flanges/boltened,leakage /breakage and ensure it is streaming freely.
- Inspection of underwater buoy hoses, integrity and configuration.
- Ensure that all hatches on spm deck are secured tightly
- Check for mooring hawser and hose pickments arrangement amd ensure that there is no entanglement or fouling of mooring gears
Boarding the tanker:-
- Confirm that the tanker pilot ladder/gangway is properly secured before boarding
- Before the tanker. it must be ensured that ship personal is standby at boarding point
- Lifejacket must always be put on when boarding/disembarking from the tanker or transfer of personnel from one vessel to another
