SHIP REPAIR & CONVERSION

Werften GmbH (owners of B+V) became a 20 percent shareholder in Lisnave. Therefore, B+V advised Falcon of the advantages of having the project carried out at

Lisnave's Mitrena yard.

Work involves removal of the existing stern-driven power sta- tion and replacing it with a new diesel-driven unit; installation of a drilling package (including steel structure for moon-pool and inter- mediate decks); installation of a dynamic positioning system; accommodation work (construction of additional cabins and heli-deck); tank modifications; and installa- tion of four 80-ton deck cranes.

The contract also includes an option for the conversion of anoth- er two ships, which will be named

Peregrine VIII and Peregrine IX.

Birkenhead's Cammell Laird has also won a conversion contract from Falcon Drilling, involving the $23 million conversion of 7,746- dwt Deepsea Worker (to be renamed Peregrine VII) from a sal- vage vessel to a dynamically-posi- tioned drillship. This contract is the largest to be undertaken at the yard and provides a timely fillip for the company's stock market ambitions.

The vessel arrived this May.

When completed, it will have been upgraded and lengthened, with a 104-ft. (31.7-m) mid-body section installed, as well as a moonpool and a new drilling substructure.

Other work will include: the fit- ting of full length sponsons 8.2 ft. (2.5 m) on each side); installation of a new drilling derrick; and com- plete design and installation of a new drilling system.

Meanwhile, Singapore's Keppel shipyard has won a conversion project from Falcon Drilling, con- verting a 12,000-dwt hull, to be named Peregrine, to a drillship.

The contract, which is valued at $43 million, is scheduled to be completed by mid-1998.

Poland's Gdansk Shiprepair Yard (Rementowa) has drydocked the 67,436-dwt NIS-registered tanker

Petrotroll for conversion to a shut- tle tanker.

Owned and managed by Golar-

Nor Offshore AS (Trondheim), the vessel will feature two new com- partments, a new forward bowthruster room, a powerplant

STB side stern, a C02 system and new exhaust ducts, pipes, cabling, etc.

Anew 1,000-kW bowthruster will be delivered by Ulstein. In the new powerplant, a 1,000 kW

Caterpillar generating set will be installed. The dynamic positioning system, which was delivered by

Autronica, will also be installed in order to improve navigation.

Some repair will be carried out as well, including extensive over- haul of machinery, fitting and elec- tronics.

In addition, a new tank measure- ment will be installed.

All work will be supervised by

Det Norske Veritas surveyors.

The U.K.'s A&P Group has won what could be the largest conver- sion contract to be placed this year from the conventional marine industry. A&P Tyne has been tapped to convert 11,403-grt RoRo ferry Ambassador 11 to a cruise casino ship for Stirling Shipping

One, in a deal worth $23 million.

The 1970-built vessel arrived on

Tyneside in August.

Work will involve the removal of 300 tons of steel, to be replaced by 400 tons, helping to create four

The PICKUPCAT concept

The PICKUPCAT concept is based on dividing a vessel in two separate parts: a self contained catamaran containing power, propulsion and steering functions, and an interchangeable cargo carrying unit.

The assembled units retain the same strength and structural properties as that of a traditional hull construction. The time spent in port to engage/disengage tjie two separate units take less than 2 hours. The cargo unit may serve as a floating storage facility, independently of the propulsion unit which is free to operate elsewhere.

While at sea, the two units operate as one ship.

Digital Gyro Repeaters

Scandinavian micro systems1 • Large super-bright Digital Heading Display. • Analog Turning Indicator - allows instant estimation of the ship's turning rate. • Will work from most types of gyro compasses. • Repeaters can be "daisy chained" and synch- ronized to first repeater (Master Repeater). • Digital Data output. NMEA and various other protocols are available for integration with survey and navigation computers.
