Finnish technology company Wärtsilä has received an order from Norway-based Knutsen OAS Shipping for the delivery of a further three Compact Reliq reliquefaction plants.

With the latest contract, Wärtsilä’s orders from this customer have reached eight in total, with two received in 2020 and three received last year.

The reliquefaction plants will be installed on eight new liquefied natural gas (LNG) carrier vessels, which are currently being constructed for Knutsen OAS.

The vessels are being built at the Hyundai Heavy Industries (HHI) yard in South Korea.

Based on reversed nitrogen Brayton cycle refrigeration technology, the Compact Reliq solution reliquefies the boil-off gas (BOG) from gas carriers and LNG bunker vessels.

The solution also helps to keep cargo cool in all operating conditions.

The Compact Reliq plant allows a portion of the BOG to be used as fuel for the ship’s engines, while the excess amount can be marketed as part of the LNG cargo, stated Wärtsilä.

Wärtsilä Gas Solutions sales manager Lasse Bergerud-Wichstrøm said: “These orders strengthen even more our relationship with both Knutsen OAS and HHI. The Compact Reliq is a system that perfectly meets the needs of the market, and these orders are a clear endorsement of that fact.”

Last week, Wärtsilä secured a contract for the supply of its hybrid propulsion system for three new RoPax ferries being built for Swedish company Stena RoRo.

These new vessels will be chartered to Brittany Ferries as part of a long-term agreement.

They will operate between Portsmouth, UK, and the French ports of St Malo and Caen.
