Wartsila Power for an Extremely Cold Climate
01 Jun 2004
Wartsila Corporation has received and order for four engines for installation on the first Sakhalin icebreaker to be built by the Kvaerner Masa-Yards Shipyard inFinland. The vessel will be equipped with three 8 cylinder Wartsila 38 main engines in diesel electric drive and an additional 6 cylinder Wartsila 20 engine to power a harbour/ emergency genset.
Scheduled for delivery to Russia's Far Eastern Shipping Company (FESCO) in 2005, the vessel will have a maximum length of 100m and a shaft output of 13MW. The Wartsila 38 engines will each have an output of 5,800kW at 600rpm and the Wartsila 20 engine will have an output of 1,080kW at 1,000rpm. The engines are scheduled for delivery to Kvaerner Masa-Yards during autumn of this year.
FESCO will operate the icebreaker as a stand-by and supply vessel in Russian waters in the Sea of Okhotsk in the region of Sakhalin Island north of Japan. Conditions in the region are extremely demanding.
Air temperatures can drop below -40ºC, ice banks can be as high as 20m, and solid ice can be more than 1.5m thick.
For these reasons, the new icebreaker's design is based on the double acting ship (DAS) concept developed by the Masa-Yards Arctic Research Centre (MARC) and now a standard in Arctic operation.
The ship breaks thick ice by going astern, reducing power consumption while also allowing the vessel's bow to be optimised for sailing in open waters.
