Wartsila power for Russian icebreaker
Wartsila Corporation has received an order for four engines for installation on the first Sakhalin ice breaker to be built by the Kvaerner Masa-Yards shipyard in Finland. 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 harbor/emergency generating set.
Kvaerner Masa-Yards has been commissioned to design and build the icebreaker by the Russian Far-Eastern Shipping Company PLC (FESCO). Scheduled for delivery in 2005, the vessel will have a maximum length of 100 m, a deadweight of 4,000 tons and a shaft output of 13 MW. The Wartsila 38 engines will each have an output of 5,800 kW at 600 rpm and the Wartsila 20 engine will have an output of 1,080 kW at 1,000 rpm. The engines are scheduled for delivery to Kvaerner Masa-Yards this fall.
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 to below minus 40 degrees C, ice banks can be as high as 20 metres, and solid ice more than 1.5 meters thick.
For this reason the design of the new icebreaker is based on the DAS (double-acting ship) concept developed by the Masa-Yards Arctic Research Centre (MARC) and now a standard in arctic operation. This means that the ship breaks thick ice by going astern. It reduces power consumption while also allowing the vessel's bow to be optimized for sailing in open waters.
