Finland-based Wärtsilä has won a contract to provide a host of solutions to four newbuild tanker vessels, which will be built at Avic Dingheng shipyard in China.
As part of the contract, Wärtsilä will supply a 9-cylinder Wärtsilä 34DF dual-fuel main engine, two Wärtsilä Auxpac 20 auxiliary engines and gas valve units, and a controllable pitch propeller (CPP) compliant with Ice Class 1A for each of the vessels.

It will also supply 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 begin the delivery of the equipment from next year.
Three Swedish companies including Furetank (two vessels); Älvtank; and Thun Tankers, a fully owned subsidiary of Thunbolagen will own the newbuilds.

By GlobalDataTo be mainly powered by liquefied natural gas (LNG), the vessels will also fulfil the International Maritime Organization’s (IMO) Tier III requirements.
Wärtsilä marine solutions sales vice-president Aaron Bresnahan said: “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.”
The deal will see the company also provide a gearbox and shaft alternator equipped with ‘take-me-home’ functionality.
Wärtsilä said that it had used its OPTI Design methodology in a bid to realise optimal propulsion efficiency for the four new vessels.
The methodology uses accurate information through computational fluid dynamics (CFD) analysis to calculate the performance of the propeller, nozzle and rudder of a vessel.
Compared to similar class vessels built between 2002 and 2012, the four newbuilds will be able to reduce around 50% of CO2 emissions.
