Wärtsilä Cargo Handling System for Fully Refrigerated Gas Carriers

Wärtsilä Gas Solutions has long been the preferred cargo handling system supplier for many of the leading owners of fully refrigerated gas carriers. When transported in these ships, the LPG is normally kept at its coldest temperature (atmospheric pressure) and the required equipment needs to be extremely reliable.

Our innovative and energy efficient solutions, together with the broadest portfolio of reliquefaction configurations, has given Wärtsilä a leading position in this market. This extensive offering is supported by Wärtsilä’s unmatched global service network.

    Technical info

    An improved process for high Ethane

    • The new Wärtsilä reliquefaction process with an increased pressure design enables the handling of lighter cargoes, such as propane with a high ethane content of up to 8-9%, which is common with shale gas processing plants
    • The new design features two intercoolers with a ​flash-in-series ​arrangement to provide ultimate plant performance
    • With full condensing against seawater for even lighter cargoes, there is no need for complicated vent gas cooling systems
    • No vent gas cooling means high performance throughout the entire cargo range
