Displacement: 20000 t
Client: Moss Arctic Production
The multi-purpose bare - deck platform Moss - 50 represents the 5th generation of deep water semi-submersible platforms designed by the Norwegian engineering company Moss Maritime.
The project provides for maximum functional flexibility in alternative arrangement of upper decks with a view to the end use of the platform:
- exploration drilling platform;
- production platform;
- crane platform etc.
The bare deck is strong enough to accommodate a topside structure weight up to
20 000 t.

In columns there installed tanks for baryte, bentonite and cement with corresponding pneumo - transporting system. There is a possibility to install an anchorage system for operation at sea depth to 1500 m or dynamic positioning system for operation at sea depth to 3000 m.
Length over all……..………118,6 m
Width overall………………..72,5 m
Height to main deck………..40,65 m
Hull weight on delivery……15 000 t
The multi-purpose bare-deck platform was built in the shortest time:
November 2000 – start of steel cutting;
October 2001 – launching of the pontoons;
May 7, 2002 – delivery of the ready platform to the Customer and towage to the destination place.
