Wärtsilä wins two more regasification module contracts for LNG vessels

South Korean shipyard Hyundai Heavy Industries (HHI) has placed two contracts with Wärtsilä for seawater/propane based regasification modules.

The systems are to be installed on FSRU (Floating Storage and Regasification Unit) vessels owned by Höegh LNG, the Norway-based owner and operator of floating energy solutions, and by Russian energy company Gazprom.

The contracts were signed in July. There is also an option for a further contract from HHI for another Höegh vessel that is valid until December of this year.

Both regasification systems are modularized for easy installation. They will also be supplied with seawater filter and steam/seawater heating modules. The system to be supplied for Gazprom will be winterized so as to be capable of operating in ambient temperatures as low as minus 30°C.

The use of Printed Circuit Heat Exchangers and Plate Heat Exchangers enables the systems to be far more compact and lighter than alternative solutions. By utilizing seawater for heating, CO2 emissions are far less than solutions using steam heating.

Wärtsilä has delivered and commissioned numerous floating LNG regasification plants based on either closed loop regasification technology, using steam with water/glycol as the intermediate heating medium, or open loop regasification technology using seawater with propane as the intermediate heating medium.

The company has also delivered modularized regasification plants for jetty installations. These facilitate a much shorter construction time compared to conventional land-based LNG regasification terminal projects.
