Avenir LNG awards reliquefaction plant contract to Houlde

Avenir LNG has awarded a reliquefaction plant contract to Houlder for its 20,000-cbm LNG bunkering and supply vessel, Avenir Achievement.

Houlder bagged the detailed design and engineering for the retrofit of an Air Liquide boil-off Gas (BOG) reliquefaction plant.

This work follows the successful completion of basic design and engineering by Houlder in the first quarter.

Starting in the first quarter of 2023, the vessel will serve LNG giant Shell for a period of three years with an option to extend up to five years.

Avenir took delivery of this vessel from China’s Nantong CIMC SOE in May. Avenir Achievement and its sister vessel, Hai Gang Wei Lai, which Avenir sold to a Chinese JV, are the world’s largest LNG bunkering ships.

According to Houlder, the installation of the new subcooler plant would take place at the end of 2022, ahead of the vessel’s charter with Shell.

The system prevents losses during idle periods, permitting reliquefication of received cargo vapor after bunkering operations, further reducing wasted cargo and greenhouse gas emissions, it said.
