Wärtsilä Power for Heavy-lift Conversions
Wärtsilä diesel-electric propulsion plants have been ordered for two heavy-lift transport vessels to be converted for Fairmount Heavy Transport NV, an associated company of the Rotterdam-based towage contractor Fairmount Marine BV. The vessels, the Fairmount Fjord and Fairmount Fjell were originally semi-submersible barges and are being converted to self-propelled heavy-lift transport vessels. The propulsion plants were contracted in August 2005 from a consortium formed by Wärtsilä and the Dutch company Imtech NV, a specialist in electrical installations and integrated bridge systems.
For each vessel, Wärtsilä Corporation will deliver three Wärtsilä diesel generating sets, two Lips steerable thrusters and a Lips bow thruster. The three 8-cyliner in-line Wärtsilä 32 diesel generating sets each have a maximum continuous power output of 3840 kW at 720 r/min. The sets will supply electrical power to two 4500 kW steerable thrusters having a fixed-pitch propeller of 3400 mm diameter in a high-performance HR nozzle. The 1500 kW bow thruster will have a 2250 m diameter controllable-pitch propeller. The diesel-electric propulsion plants will give the vessels a service speed of 12 knots.
The Fairmount Fjord has dimensions of 164.3 m length between perpendiculars, 45.5 m breadth and 9 m depth. The Fairmount Fjell has dimensions of 146.3 m length bp, 36.0 m breadth and 9 m depth. When the conversions are completed in the second half of 2006, the vessels will be primarily employed in the transport of offshore equipment such as jack-up and semi-submersible drilling rigs, and floating production units for the offshore oil and gas industry.
