BMT Nigel Gee, UK has designed a Windfarm Service Vessel incorporating technologies to enhance the operational efficiency of the craft. It has an aluminum hull of LOA 64 ft (19.4 m), beam 23 ft (7 m) and draft of 3.2 ft (1 m). Propulsion is by twin MTU 8V2000M72 each rated at 720 kW (965 hp) and powering a Hamilton type 571 waterjet. Considerable thought has gone into the practical aspects of the vessel’s duties. Passenger and crew comfort is improved by the use of a resiliently mounted superstructure. Going bow-on to the wind turbine column is simplified using a patented Active Fender System so that a (wind) Turbine Access System (TAS) can be deployed. [More]

Last month the keel laying ceremony for the Alaska Region Research Vessel (ARRV) R/V Sikuliaq, took place at the Marinette Marine Corporation (MMC) shipyard in Marinette, Wisconsin. The LOA is 261.5ft, maximum beam 52.0ft, draft is 19.5ft and loaded displacement is 4,065 long tons. She has a maximum speed of 14 kn in calm water. Several challenges had to be overcome in the design of the propulsion system for this research ship. Two Siemens main propulsion motors drive each pod. Electric power on board is supplied by two MTU 16V4000 plus two MTU 12V4000 gensets. Completion date for the vessel is April 2013. [More]

Construction of the fourth FREMM European multimission frigate has begun at Fincantieri's shipyard in Riva Trigoso, Sestri Levante, Italy. The Italian Navy plan ten ships built by Fincantieri: the French Navy plan to take a total of eleven ships, to be built by DCNS at Brest and at Toulon. The Moroccan Navy has ordered one frigate from DCNS for delivery in 2013 and the Greek Navy has expressed interest for four FREMMs with an option for two more. The ship length is 113 m, beam 19 m and displacement 5,600 tonnes and uses a CODLAG propulsion arrangement. Under diesel electric power the maximum speed is 15 kn and when combined with the gas turbine 28 kn. [More]

Capsize-proof MTU Engine for UK RNLI 'Severn-class' Lifeboat

If a British RNLI (Royal National Lifeboat Institution) ‘Severn-class’ lifeboat bent on a lifesaving mission in foul weather were to capsize, it is designed to upright within seconds (the righting lever must be a long one) but how can the engine keep running after the boat has ‘looped the loop’? Inverting a running diesel engine would likely cause engine oil to enter the cylinders through the crankcase ventilation system, causing uncontrolled combustion as surely as pressing the self-destruct button. A few years ago, the RNLI was looking to re-engine its ‘all weather’ boats and asked MTU if they could tackle the problem.The Revolving Cradle Test-bedMTU design engineers took their Series 2000 M94 engine and fitted it to a special-purpose cradle that would rotate it through 360 degrees about its own longitudinal axis in order to study closely and practically the effectiveness of modifications they made to the design of the crankcase ventilation and oil...
