First UT722LX enters serviceVessel & ROV News // February 28, 2003
This 'super-long' version of the UT722 anchor handler has extra space for very large capacity winch for synthetic fibre rope, as well as wire rope and chain, without compromising cargo deck capacity or area. Compared with a standard UT722, Havila Borgstein also has significantly more underdeck supply storage space.
Havila Borgstein was built by Langsten AS, part of the Aker Yards group, and is owned by Island Offshore II. On delivery from the shipyard in west Norway in January 2003, the vessel went straight out to West African waters where its first task is a platform move in 1,600m of water off Angola.
The UT722LX is a deep water anchor handling tug supply and service vessel with FiFi I, Oil Rec, Ice C, DYNPOS AUTR and Clean Comf C(3) V(3) class notation.
With a length overall of 87.7m, the ship's deadweight is about 3,170 tonnes on a maximum draft of 6.6m. The cargo deck measures 36.5m by 15.3m and approximately 1,100 tonnes of deck cargo can be carried. The heart of the vessel is the Rauma Brattvaag hydraulic winch outfit.
Rolls-Royce says the generic UT722LX has a nominal bollard pull of 220 tonnes, although on sea trials Havila Borgstein achieved a bollard pull of 237 tonnes.
The ship's owners also specified a very large chain stowage - 851m3 distributed among six chain lockers.
