Wärtsilä, the marine industry’s leading solutions provider, has strengthened its position as the global leader in supplying design and propulsion solutions for Liquefied Natural Gas (LNG) Platform Supply Vessels (PSVs) with yet another important order.


The new Platform Supply Vessels (PSVs) for Eidesvik Offshore will include an integrated Wärtsilä gas power solution featuring the recently launched Wärtsilä 20DF engine. Norwegian operator Eidesvik Offshore has placed an order for its fifth gas PSV. This latest order further demonstrates Eidesvik’s position as the world leader in environmental friendly gas powered PSVs.

All Eidesvik’s gas PSVs, including this latest order, are designed by Wärtsilä and utilize Wärtsilä’s unique dual-fuel technology. In addition to the complete design of the vessel, Wärtsilä’s scope of supply for the new PSV includes the dual-fuel main engines and generating sets, the electrical power and propulsion system, integrated automation, and the power management system. The vessel will be fitted for use in arctic waters with ‘winterization’ and de-icing solutions, and is to be built at Kleven Verft in Norway.

Wärtsilä at the forefront in environmental vessel solutions

The new Wärtsilä VS 489 Gas PSV design represents a state-of-the-art vessel. It features outstanding energy efficiency, a unique hull form, fuel flexibility, and outstanding vessel performance in areas such as fuel economy and cargo capacity. The Eidesvik orders include a unique configuration of the gas electric propulsion system. This is based on a combination comprising the Low Loss Concept for Electric Propulsion, the Wärtsilä 34DF main engines, and the recently introduced Wärtsilä 20DF engine. The dual-fuel units enable, in addition to heavy fuel oil (HFO) and marine diesel oil (MDO), the use of gas as a main fuel for marine applications. Wärtsilä’s ability to offer total concept solutions that include the design of the vessel, the propulsion plant, electrics and automation, and a host of fuel saving and environmentally sustainable options, has given the company a notable competitive edge – particularly in the area of specialty vessels such as Gas PSVs.

The Wärtsilä 20DF engine is the latest addition to the company’s complete portfolio of dual-fuel engines. This industry leading technology offers the marine sector numerous benefits, including the primary advantage of having the flexibility to utilize different fuels. At a time of uncertainty in the cost of liquid fuels, and as environmental legislation becomes increasingly stringent, this flexibility enables the use of cost-efficient and environmentally friendly LNG as the main fuel. In case of interruption to the gas supply, Wärtsilä DF engines automatically switch to diesel mode operation without any loss in speed or power output. Single fuel installations obviously lack this additional level of operational safety.

“The combination of our unique design capabilities, and the introduction of the Wärtsilä 20DF dual-fuel engine, means that the customer will have a highly efficient vessel to operate in all conditions. The energy efficiency, cargo capacity and overall performance are all outstanding,” commented Tor Henning Vestbøstad, Sales Manager, Wärtsilä Ship Design. Vestböstad also emphasises the company’s excellent collaboration with both Eidesvik and Kleven, which has been an important factor in the success of this project.
