Wärtsilä to Deliver Engines for Swedish LNG-Fuelled Tankers

Wärtsilä, the provider of LNG fuel solutions to the marine industry, has received a contract to provide engines and propellers for four new Swedish liquefied natural gas-fuelled (LNG) tankers, which will be constructed at China’s Avic Dingheng shipyard.

Two of the ships will be built on behalf of the Swedish owner Furetank, one will be built for Älvtank, and one for Thun Tankers, a fully owned subsidiary of Thunbolagen.

Upon delivery, the vessels, which will fulfil the IMO’s Tier III requirements and be primarily fuelled by LNG, will be commercially managed by Furetank Chartering in the Gothia Tanker Alliance.

Under the contracts, signed in the second quarter of 2016, the scope of Wärtsilä’s supply to this project comprises a 9-cylinder Wärtsilä 34DF dual-fuel main engine, two Wärtsilä Auxpac 20 auxiliary engines, the 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, and two Wärtsilä deepwell ballast pumps with a frequency control system.

Wärtsilä will also supply the vessels with a gearbox and shaft alternator having ‘take-me-home’ functionality. This provides propulsion power to the auxiliary engine should the main engine be out of operation for any reason, thus allowing the vessel to return safely to port, according to the company.

Delivery of the Wärtsilä equipment is scheduled to commence in spring 2017.

The vessels will be built to a design developed by Swedish ship designer FKAB together with Furetank, which focuses on minimising the impact on the environment, with a close to 50% reduction in CO2 emissions over similar class vessels built between 2002 and 2012, according to Wärtsilä.
