Evergas’ new LNG carrier series features an integrated Wärtsilä equipment package

Wärtsilä has received an order to supply a package of equipment for a series of LNG carriers being built at Sinopacific in China, for Danish operator Evergas.

Wärtsilä's scope of supply includes dual-fuel engines and propulsion equipment. Additionally, the ships are designed to carry and reliquefy ethane and LPG as well as LNG, using a cargo handling package supplied by Wärtsilä.

Efficiency and fuel savings will be gained through the use of the Energopac rudder, which lowers resistance and increases propulsion power. The ships will operate primarily on LNG, enabling compliance with current and anticipated environmental legislation, including IMO Tier III limits. The dual-fuel technology provides operational flexibility and redundancy, by allowing the use of conventional fuels as an alternative, while at the same time the integrated LNG fuel system enables operation on natural gas fuel independently of the cargo carried.

"The customer's essential requirements for these vessels are to achieve the operational and fuel efficiencies needed to optimize their operating costs, while at the same time complying with the upcoming Tier III environmental regulations," said Aaron Bresnahan, vice president sales, Wärtsilä Ship Power. "The advanced technology solution to be provided by Wärtsilä, whereby the cargo handling system, the gas supply system, and the propulsion machinery are fully integrated with each other, will make the vessels the most modern and environmentally sustainable LNG carriers ever built."

Martin Ackermann, CEO of Evergas said: "We have enjoyed a lengthy and trusted relationship with Wärtsilä. This, together with Wärtsilä's relentless efforts in understanding and adapting to our demands, has enabled us to successfully achieve a total integrated solution. I am convinced that our Dragon 27500 series will be a benchmark in the LNG carrier markets."

The integrated systems solution combines individual Wärtsilä solutions in an optimised package. For example, the LNG supply system is integrated with the cargo handling system so that it can be used to cool the cargo, providing further energy savings.
