MAN Supplying LNG System For Cargo Ship
By Jack Burke10 September 2019
MAN Energy Solutions’ marine liquefied natural gas (LNG) fuel-gas-system manufacturer will supply an LNG fuel-gas supply system for a multipurpose palletized cargo and refrigerated vessel newbuild, also known as a LoLo (Lift-on/Lift-off).
The vessel for Norwegian shipowner Egil Ulvan Rederi is designed by Førde, Norway designer Multi Maritime. The designer already counts a number of LNG-powered vessels in its portfolio. The MM85CC design will be built at Tersan Shipyard in Turkey. Tersan has, over the years, also built quite a number of LNG-powered vessels and this will be the sixth such vessel since 2016 that it will outfit with a marine fuel-gas system delivered by MAN Cryo. The newbuild is scheduled for delivery in late 2020.
“MAN Cryo has been chosen as supplier for the LNG fuel-gas system based on the company’s track record of complex LNG solutions,” said Arild Hoff, CEO at Egil Ulvan Rederi. “There was no doubt early in the process that MAN Cryo was the preferred supplier because they showed the right level of understanding and knowhow to meet our requirements.”
Louise Andersson, Head of MAN Cryo, said the specialized vessel makes unique demands for reliability and redundancy and the company offered an innovative solution that includes a vertical fuel tank.
“Ulvan’s interest in clean technology goes hand in glove with our ambition to become a leading supplier of LNG-fuelled solutions,” Andersson said. “We are also very happy to work once more with such a valued customer as Tersan, and look forward to developing our relationship even further in the future.”
MAN Cryo’s scope of supply for the vessel covers:
· a vertical, vacuum-insulated 364 m3 LNG tank
· a complex tank-connection space with two redundant LNG supply trains, based on both a pump and a pressure-build-up unit
· an LNG cold-recovery evaporator
· an integrated bunker station (BS100-GR).
Upon construction, the 3,500 dwt-vessel will have a length of 86 m and breadth of 19.5 m and will service the round trip between Tromsø in northern Norway to Østfold in the southeast. The vessel is a multipurpose design with reefer capacity, a refrigerated hold and elevators for palletized goods, as well as the capability to discharge fish food at fish farms along its route.
Worldwide, just a few vertical LNG tanks are in operation that are classed for marine applications. MAN Cryo has produced vertical LNG tanks for marine fuel-gas systems since 2011 and can cite reference projects ranging from 89 to 400 m3 gross volume.
Vertical tanks offer an alternative to horizontal tanks and bring many advantages, including less impact on stability due to smaller liquid surface; less likely to create sloshing; increased hydrostatic pressure, facilitating fuel flow.
MAN Energy Solutions took over fuel-gas specialist Cryo AB in 2015 and fully integrated it into its business. Under the brand MAN Cryo, the company offers systems for the storage, distribution and handling of liquefied gases.
