The tankers each have a length of 140 m, a 4.2 m draft, and a deadweight of 6,979 tons. When launched, all 25 owill operate on Russia's inland waterways during the summer and on the Black and Mediterranean Seas in winter. They can carry crude oil and petroleum products, including gasoline, without restrictions for flash-point, and are allowed to transport two types of cargo simultaneously.
Two 6-cylinder Wärtsilä 20 main engines will be supplied for each vessel. Delivery of the machinery will commence in the autumn 2011, and should be completed by mid 2013. The first vessel is scheduled to be fully operational by the end of 2012.
"We have previously supplied Volga Shipping with Wärtsilä engines, and have established a constructive relationship with the company over the years. When these tankers were being planned, and the need arose for reliable and economical shipsets, Wärtsilä engines were the obvious choice. We are very pleased and proud to announce that this is the single largest order for Wärtsilä 20 marine engines that Wärtsilä has been awarded in Russia," says Johan Hansten, Director Business Sales, Wärtsilä Ship Power.
The 6-cylinder in-line 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.
This engine has proven its robustness and reliability over the years, with more than 4000 Wärtsilä 20 engines having been delivered since being introduced to the market in the early 1990s. The Wärtsilä 20 covers the lower power range in the Wärtsilä diesel engine family.
