Rolls Royce Designs and Equipment for Coastguard ETVs
01 Dec 2003
Two important orders have been placed very recently for Government funded Emergency Towing Vessels (ETVs). Both France and Norway are to have sophisticated vessels built and operated under commercial contracts. The designs selected for the new contracts, one new ship for Norway and two for France, are from the design team at Rolls Royce in Ulsteinvik, Norway.
A new design, the UT512, is to be built for the Norwegian coastguard and will carry out a wide variety of duties, including patrolling, fisheries protection, emergency standby, pollution control and towing. Rapidly increasing tanker traffic along the coast of Norway, especially in the far north, has raised fears of extensive pollution in the event of a tanker grounding.
An important role the vessel will therefore be towing and pollution prevention. Operating along the full length of Norway's coastline and throughout the country's exclusive economic zone will involve considerable time in the Barents Sea. With that in mind, Ice class 1B has been specified, along with anti-icing measures such as heated shelters for the two MOB/boarding boats. The 83m-long ship will be owned and operated by Remoy Shipping, on long-term charter to Kystvakten. With patrolling as one of its tasks, the ship will have fast boarding/rescue boats, a gun on the foredeck and a comprehensive civil and military communications system.
The hull and major steelwork will be completed by Aker Tulcea in Romania and Soviknes Verft will fit out the vessel.
Rolls-Royce will also provide a complete package of equipment.
The main propulsion engines will be two 8-cylinder Bergen B32:40 units turning CP propellers in fixed nozzles. Tenfjord steering gear will operate the rudders, and there will be a Kamewa Ulstein tunnel thruster and a retractable Ulstein Aquamaster azimuth thruster in the bulbous bow. A high-speed performance of about 20 knots is expected and bollard pull of more than 100 tonnes.
A Rauma Brattvaag deck machinery package has been specified, comprising a main towing winch with a 150-tonne brake load, anchor windlass, capstan and tugger winch.
This will be the first coastguard vessel to be fitted with the new Rolls-Royce dynamic-positioning system, and it is to have a full UMAS automation system.
A specially developed UT515 design has been chosen for the two new French ETVs.
Myklebust Verft of Sunnmore, Norway, a Kleven Maritime company, has signed a contract valued at NOK 400 million to build the vessels for Les Abeilles International, a member of the Bourbon Group. Les Abeilles International in Le Havre, has signed a long term contract with the French Navy to provide ETV services on the French coast. The vessels are designed to carry out towage, salvage and standby services and help reduce the possibility of disasters such as the Erika and Prestige incidents in the future.
The French ETVs will be 80m in length with a breadth of 16.5m, powered by 16,000kW main engines for a bollard pull of 200 tonnes and free running speed of 19.5 knots. Delivery is scheduled for February and June 2005.
