California-based ACD, a Cryogenic Industries Company, has successfully passed its First Article Test (FAT) for their LNG fuel gas pump system — the MSP-3SLH, Dual — which will be installed in and fuel TOTE’s Marlin Class containerships. These liquefied natural gas-powered containerships, claimed to be the first in the world, will operate between Jacksonville, FL and San Juan P.R. The containerships will be ABS classified.
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 (4,640 psi) at flow rates from 1.4 m3/h to 11 m3/h (6 gpm to 48 gpm). ABS, USCG, TOTE, Shinhan Machinery (DSME subsidiary) and NASSCO (General Dynamics – shipyard) were in attendance and witnessed the testing. ABS approved the LNG fuel gas pump system.
First article testing (FAT) includes the necessary inspections, tests and documentation to ensure all product characteristics conform to drawings and/or specifications. (See Editor note below.)
The high pressure LNG fuel supply system includes two ACD model MSP-3SLH high pressure pumps with hydraulic motors and HPU. Also included is an external oil lubrication system all integrated on a common skid with piping, high & low pressure control valves and all monitoring equipment.
“This is a significant milestone for ACD and the LNG powered marine market. 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,” said James Estes, Managing Director of ACD.
ACD is an Original Equipment Manufacturer of cryogenic pump systems and turboexpanders.
