Verft. The new UT742 design will be capable of carrying out a wide range of underwater tasks and will also have the power and winch equipment to be a formidable deep- water anchor-handler. "This contract underlines

Ulstein's role as a pioneer com- pany in the development and supply of advanced specialist vessels," said Brynjulv

Mugaas, group director. The

UT742 has been developed with close cooperation between

Solstad, charterers and the design division of Ulstein

International. Delivery is scheduled for the first quarter of 1999, and Solstad has already been awarded a five- year commission for the vessel.

The new vessel will feature a 312-ft. (95-m) long hull, a 79-ft. (24-m) beam, 1,000 sq. m. of working deck space and full dynamic positioning and will be used for subsea installa- tions, light drilling, work on satellite wells, laying pipes between wellheads and platform, ploughing-in pipeline and ROV services. The ship will be fitted with a 150-ton A-frame featuring two moonpools, one for ROV opera- tions and one for general work.

Propulsion power totals approxi- mately 27,500 hp and is provided by four medium-speed main engines geared to twin CP pro- pellers assisted by a 2,000-hp swing-up azimuth bowthruster resulting in a bollard pull of approximately 2,700 tons.

Electrical power is produced by twin 3,500 kW shaft generators and four diesel generator sets totaling 4,800 kW.

With a passenger capacity of 70, the new vessel is the 16th to be ordered by Solstad from Ulstein, and marks the eighth contract

Solstad has entered into with

Ulstein.

Ulstein Propeller Division

Ulstein Propeller Division has received a large order for thruster equipment for a series of 190 ft. (58 m) long offshore supply vessels to be built for Edison Chouest

Offshore at Ingalls Shipbuilding's

Pascagoula yard. The project is part of a contract under which

Ingalls will build a series of seven vessels for Edison Chouest, with an option for seven more, all to be used for operation in the Gulf of

Mexico. The contract value for the

Ulstein-supplied equipment is approximately $6.6 million, which would double if the option is exer- cised. Propeller equipment on each vessel comprises two Ulstein 900H Z-drives for propulsion and also features the first application of Ulstein's innovative Combi (Continued on page 32)
