LNG Industry,

Hyundai Heavy Industries Engine & Machinery Division (HHI-EMD) has awarded Cryostar a contract to supply high pressure fuel gas pumps for two LNG carriers to be built for Knutsen OAS at HHI in Ulsan, South Korea.

The pumps will be fitted in the Hyundai-designed fuel gas supply system (Hi-GAS) to feed the MAN ME-GI main engines. The marine-ready pumps will operate at cryogenic temperatures and will raise the fuel feed pressure to 300 bar.

The gear-driven triplex units feature three identical vacuum insulated pumping chambers (cold ends) to reduce cool-down time and heat in-leak both while in operation or in standby mode. The pumps are based on Cryostar's proven technology and are selected from a range of models with flows that will meet various engine fuel gas requirements. Low speed operation ensures a long equipment life with lower maintenance costs.

The pumps are skid-mounted and equipped with engineered inlet manifolds and pulsation dampers. This helps to ensure a consistent flow with minimum pressure fluctuations. The gearbox design features an integrated lubrication system, meets stringent on-board specifications and is designed for long maintenance intervals. Drive motors are rated for installation in Zone 1 hazardous areas and instrumentation is fitted to ensure smooth safe operation.
