Wärtsilä has received a contract to supply the main engines for a series of 25 tankers being built for Volga Shipping Co., a Russian shipping company. Fifteen of the ships are to be constructed at the Okskaya yard in Navashino for ship owner Volga Flot Tanker, and the other 10 at the Krasnoe Sormovo yard in Nizhny Novgorod, with five for Bash Volga Tanker and five for Volgotrans. All three ship owners are part of Volga Shipping Co.
The scope of the supply includes two, 6-cylinder Wärtsilä 20 main engines to be supplied for each vessel. Delivery of the machinery will start in fall, and finish by mid-2013. The first vessel is scheduled to be fully operational by the end of 2012, Wärtsilä said.
The 6-cylinder inline Wärtsilä 20 is part of the Wärtsilä 20 series, and is a four-stroke diesel engine that can be run on either marine diesel oil (MDO) or heavy fuel oil (HFO). It can be switched from MDO to HFO and vice versa without power interruption at any engine operation load, the company said. The Wärtsilä 20 covers the lower power range in the Wärtsilä diesel engine family.
The tanker type has a length of 140 m, a 4.2 m draught and a deadweight of 6979 tons. It can carry crude oil and petroleum products, including gasoline, without restrictions for flashpoint, and is allowed to transport two types of cargo simultaneously. When launched, all 25 of these tankers will operate on Russia’s inland waterways during the summer months, and on the Black and Mediterranean Seas in winter, according to Wärtsilä.
