P58/P62 FPSOs - Petrobras, Brazil





• Mooring clusters





• Movable chain jack with combined chain handling and chain jack handling system.

• Typical speed is 1-1½ m/min.

• The chain rests on separate chain stoppers when passively moored.

• Load measurement takes place in the chain stopper.

• Chain jack is based on Roller RamWinch design.





• Tugger winch

• Powered turndown sheave for handling chain to and from chain locker.

• Gantry with lifting gear and skidding system. Chain jack to be lifted and secured under gantry during skidding operation.

• Chain jack with main hydraulic cylinder and secondary chain stopper.

• Chain stopper with loadcells for tension measurement.





Full scale testing at Aker Pusnes in Arendal, Norway





• Full scale testing.




Goliat FPSO - Eni Norge AS, Norway

• The Goliat Field, Norway

• Sevan 1000 FPSO

• 14 x Pusnes Fairlead Chain Stoppers™

• 3 x Pusnes Movable Windlasses™

• Chain size 84mm/165mm R5

• Water depth 400 m

• Figure depicts the movable windlass with A-frame for chain handling.

• The windlass can be equipped with hydraulic or electric drive – in this case electric.

• Speeds are project specific. Typical speed = 2 - 4 m/min.

• The chain rests on separate fairlead chain stoppers when passively moored.

• Passive load measurement takes place in the fairlead chain stoppers.

• Approximate tension can be read via motor torque readings during pay in/out.



1. The chain is lifted clear of gypsy wheel after tensioning is finished.

2. Winch unit is skidded away from actual mooring line.

3. Mooring chain is lowered below winch foundation level.

4. Winch unit is then skidded back and lifts the A-frame before skidding together to the next mooring line.



• Entrance for cabling and hoses.

• A-frame to be skidded together with winch unit.

• Electric or hydraulic drive through planetary gears.

• Skidding system (relocation system).





• 3D image showing sector of FPSO.
