EUROPEAN WORKBOAT MARKET

Dutch influence evident in U.K. newbuilds

Richard Dunston (Hessle) Ltd., one of the U.K.'s leading steel workboat builders, has recently completed a 487-grt tug/workboat in an interesting joint venture with parent company Damen Shipbuild- ers. A standard Damen hull was constructed in Holland, towed across the North Sea to the U.K. where it was lengthened by 26 ft. (8 m) to a length overall of 132 ft. (40.3 m) with a beam of 31 ft. (9.5 m). De- signed for versatile offshore opera- tions, Annelies, as the vessel has been named, is currently helping

Annelies achieved a bollard pull o 44 tons and a free running speed o 12 knots during trials off the En glish north east coast.

Her wheelhouse is fitted out wit electronics and engine controls ar provided at four positions — fore, aft, port and starboard. The wheel- house roof has two manually con- trolled Ajax de Boer foam/water monitors fed by a 600-cu.-m/hr. firefighting pump. The vessel has capacity for 189 tons of fresh water, 10 tons of dispersant and 28 tons o foam.

Holyhead Marine Services Ltd. in

North Wales for its associated com- pany, Holyhead Towing. The com- pany admits that Llanddwyn Is- land, named after a local landmark, follows closely the format of the

Dutch company's Multi Cat design.

Measuring 70.5 ft. x 25.5 ft. (21.5 m x 7.8 m), most of the rectangular vessel is available as working deck due to a raised offset wheelhouse, which also doubles as crew messroom and galley, supported on one side by a small four-person ac- commodation unit and two vertical struts on the other. The covered space so formed at main deck level houses a 30-ton North Sea anchor handling winch and the support struts act as ducts for electrical, steering and engine control cabling.

On the forward deck, just aft of the substantial push bows, is a 44- ton/mEfferknuckleboom crane. The forward working deck is protected by hardwood and centrally located on the large aft deck is a 15-ton

Britannia quick release towing hook.

The hull space below the main deck is divided into five main areas connected by watertight doors. A forepeak with chain locker, store with hatch access to the main deck,
