Wärtsilä Corporation (Wärtsilä) Monday announced that it will provide solutions packages to four newbuild "environmentally friendly tankers," which are set run mainly on liquefied natural gas (LNG).

For each vessel, the solutions package will include a 9-cylinder Wärtsilä 34DF dual-fuel main engine, two Wärtsilä Auxpac 20 auxiliary engines, a gas valve unit, a controllable pitch propeller (CPP) compliant with Ice Class 1A, a high performance nozzle, a Wärtsilä Energopac rudder system, a Wärtsilä selective catalytic reduction (SCR) system for the auxiliary engines, 12 Wärtsilä deepwell cargo pumps, two Wärtsilä deepwell ballast pumps, and a gearbox and shaft alternator.

Wärtsilä says that, to optimise propulsion efficiency of the tankers, the company used its OPTI Design methodology, which utilises computational fluid dynamics (CFD) analysis to show propeller, nozzle, and rudder performance, including their interaction with the vessel's hull.

"Being a total solutions provider brings significant added value to our customers since delivery and scheduling risks are reduced, and the various systems can be integrated to achieve optimal performance and lower operating costs," said Aaron Bresnahan, Vice President of Sales at Wärtsilä Marine Solutions.

The ships, which will be IMO Tier III complaint, are said to be slated to be built at China's AVIC Dingheng Shipbuilding Co., Ltd. (Avic Dingheng) for three Swedish owners, including Furetank Rederi AB (Furetank), Rederi AB Älvtank (Älvtank), and Thun Tankers.

Upon delivery, the vessels will be commercially managed by Furetank Chartering Sweden AB (Furetank Chartering), and operate within the Gothia Tanker Alliance, notes Wärtsilä.

Delivery of the Wärtsilä solutions package is said to be scheduled to begin in the spring of 2017.

In April, Wärtsilä announced that it would provide propulsion packages for the conversion of two RoPax vessels of Canadian ferry operator British Columbia Ferry Services Inc. (BC Ferries) to dual-fuel conventional and LNG bunker propulsion.
