A heavy-lift vessel recently delivered four 1,350-m3 IMO Type C LNG tanks for the LNG bunker barge under construction at Fincantieri Bay Shipbuilding in Sturgeon Bay, Wisconsin
Built in Qidong, China at CIMC Sinopacific Offshore & Engineering, the four LNG tanks were transported by BBC Chartering’s heavy-lift vessel BBC Louise and are being supplied by Wärtsilä Gas Solutions for installation in a new 5,400-m3 LNG bunker barge being built for Polaris New Energy. To be named Clean Canaveral, the LNG barge will be paired with an existing ocean tug in an articulated tug barge unit.
The four cargo tanks have internal piping, instruments, equipment and access structures. The tanks, fitted with 300-mm insulation, were installed by the shipyard below deck on the bunkering barge; only the domes will be visible once completed.
The full Wärtsilä scope for this project includes, in addition to the tanks, the system design and integration, the LNG pumps, a ship-to-ship transfer system, ship-to-shore communication link, all necessary safety and control equipment, valves, instrumentation, and a gas combustion unit.
When delivered in late 2021, Clean Canaveral will be the largest capacity LNG bunker vessel operating in North America, initially serving vessels in ports along the US east coast.
The vessel will source LNG from JAX LNG, a small-scale LNG production facility in Jacksonville, Florida, created through a partnership between NorthStar and Pivotal LNG. It will be operated by Polaris New Energy, NorthStar Midstream’s marine transportation company.
NorthStar Midstream holds options to build two additional sister LNG bunker barges with Fincantieri Bay Shipbuilding.
