Wartsila has won a contract to design a new LNG powered Platform Supply Vessel (PSV) for the Norwegian operator Rem Offshore.  The vessel will be built at the Kleven Verft yard in Norway.

The new LNG powered PSV, the first such vessel for Rem Offshore, will be a Wartsila Ship Design VS499 LNG PSV, a state-of-the-art vessel based originally on the successful VS489 LNG PSV design. The ship features outstanding energy efficiency, a unique hull form, fuel flexibility, and exceptional performance in areas such as fuel economy and cargo capacity.

Wartsila’s scope of supply will also include the dual-fuel main engines and generating sets, the electrical power and propulsion systems, integrated automation, and the power management system. The selection of Wartsila’s dual-fuel (DF) technology, which enables the use of clean gas as the main fuel, will help Rem Offshore’s grow its fleet of environmentally sustainable PSVs. The DF engines can also operate on marine diesel oil if required.

Wartsila at the forefront in environmental vessel solutions

This order represents the third new contract for LNG powered PSV within a short period of time that Wartsila will design and equip.  The new-build order is further evidence of the growing global demand for Wartsila’s unique gas electric propulsion system configuration. This is based on a combination comprising the Low Loss Concept for Electric Propulsion, the Wartsila 34DF main engines, and the recently introduced Wartsila 20DF engine.

“The unique combination of our design capabilities and technology strengths enables us to provide a “big picture’ perspective that has real value, particularly in special vessels such as this one,” commented Tor Henning Vestbøstad, Sales Manager, Wartsila Ship Design.

“The integrated solution, utilizing Wartsila’s dual-fuel engines and Low Loss Concept, means that the customer will have the highest possible redundancy and reliability – and a highly efficient vessel, for operation in all conditions. The energy efficiency, cargo capacity and overall performance are all outstanding,” he adds. Vestbøstad also emphasises the company’s excellent collaboration with both Rem Offshore and Kleven, which has been an important factor in the success of this project.

A unique combination of design, technology and integrated solutions

The Wartsila 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, Wartsila 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.
