Swedish coupling manufacturer and supplier MannTek has launched a liquefied natural gas (LNG) small-scale transfer system that is up to 50% lighter than other transfer systems available on the market today. This weight saving is designed to make it safer and easier for operators to manually lift and manoeuvre the connection.
The transfer system consists of MannTek’s dry cryogenic couplings (DCCs), cryogenic break-away couplings, LNG hoses, emergency shut down, and high pressure nitrogen system. It has successfully passed a factory acceptance test and is now being used on Sirius Shipping and the Anthony Veder Group’s LNG bunker vessel, the Coralius.
“The company’s DCCs have connected and transferred LNG 20,000 times. We believe we have the most experience in cryogenic transfer in the industry,” says MannTek’s CEO Markus Bäckström. “This includes the first ferry powered by LNG, Viking Grance, and TOTE Maritime's LNG-powered container ship.”
To protect the system’s operators, the MannTek team has ensured the system achieves a number of international standards and meets the requirements of a range of regulatory bodies including SIGTTO, SGMF, ISO, and EN, as well as class approval with DNV, BV, and Lloyd's. The transfer system can also be provided with an SIL 2 certification.
The Coralius started operations in the Baltic Sea and the North Sea in September.
