ACD passes FAT for LNG fuel gas pump system

ACD, a cryogenic industries company, based in California, US, successfully passed the (first article test) FAT for its LNG fuel gas pump system. The company’s LNG fuel gas pump system, MSP-3SLH, Dual, will be installed on and fuel TOTE’s Marlin Class containerships. The containerships will be the first in the world to be powered by LNG and will operate between Jacksonville, Florida and San Juan Puerto Rico. They will be classified by ABS.

The FAT included full performance at the ship’s rated LNG fuel flow requirements from maneuvering to full-speed conditions. The system achieved 320 bar (4640 psi) at flow rates from 1.4 m³/h to 11 m³/h (6 gpm to 48 gpm). ABS, USCG, TOTE, Shinhan Machinery (a DSME subsidiary) and NASSCO (General Dynamics – shipyard) were in attendance and witnessed the testing. ABS approved the LNG fuel gas pump system. USCG had already approved ACD’s MSP-3SLH design using hydraulic motors for the high pressure pumps and the oil lube system. Included in ACD’s scope was powering the MSP-SLH dual system with an external HPU, which was also used and approved during the FAT.

The high pressure LNG fuel supply system includes two ACD model MSP-3SLH high pressure pumps with hydraulic motors and HPU. An external oil lubrication system all integrated on a common skid with piping, high and low pressure control valves and all monitoring equipment is also included.

“This is a significant milestone for ACD and the LNG-powered marine market,” said James Estes, Managing Director of ACD. “We appreciate the strong support we’ve received from DSME and their subsidiaries, NASSCO and MAN to understand requirements and meet their specifications. Being a part of TOTE’s Marlin Class of LNG-powered containerships is a special accomplishment everyone involved should be proud of.”
