Wärtsilä Powers Twin-Screw Product Tankers

Posted on April 14, 2005

Wärtsilä Corporation will supply propulsion plants for two 19,000 tdw ice-class product/checmical tankers contracted at the Turkish shipyard RMK Marine for Petromarine of Bordeaux, France.

The ships are twin-screw shallow-draught tankers able to carry 19,000 m3 of refined petroleum products and IMO Class II chemicals. They are 143 m long by 23 m beam, with a design draught of 7.85 m. They will be built to Bureau Veritas class, and ice-strengthened to ice class 1A. Their trial speed is to be about 16 knots. The vessels are due for delivery in August and December 2006.

The vessels will each have a fully-redundant propulsion plant with two Wärtsilä 8L32 diesel engines, each driving Lips 4CF13 feathering controllable-pitch propellers through a Wärtsilä SCV95-P58 reduction gearbox. The use of twin feathering CP propellers allows propulsion by either main engine or both engines for economic operation. Using two feathering propellers also minimizes drag and saves fuel when operating on one engine and one shaftline is stopped.

Petromarine has a fleet of nine product/chemical carriers in service with a further five newbuildings contracted. They specialise in coastal and short-sea trades predominantly in Europe and West Africa.
