Norway’s first LNG bunker vessel, Bergen LNG, has successfully completed sea trials and has begun operations, according to Høglund.
As Bunkerspot recently reported, Bergen Tankers, in collaboration with Westcon Yards, completed the retrofit of the vessel – the former conventional bunker vessel Oslo Tank - earlier this month.
Høglund was responsible for the supply of the LNG gas handling system and the vessel’s integrated automation system (IAS), which includes the gas control and safety system. Høglund’s participation in the project involved the supply of an LNG cargo system incorporating a single shell Type-C tank with a capacity of 850 cubic metres (cbm) and a bunkering rate of 500 cbm/h.
Other hardware and automation solutions provided by Høglund include cargo pumps, bunker manifolds, custody transfer system, a ship-to-ship transfer system, a cargo control and emergency shutdown (ESD) system, and ship-to-shore/ship-to-ship link systems to create the automation system.
As part of the project, Høglund worked closely with partners HB Hunte Engineering - which provided a 3D detail design of the gas piping system - and LNG cargo tank manufacturer Gas & Heat Spa.
Westcon Shipyards, which was contracted by Bergen Tankers, carried out the conversion of the vessel, including the installation of the LNG cargo system supplied by Høglund.
Closer to the completion of the project, Høglund’s team of field service engineering professionals carried out a series of sea and gas trials of the installed equipment, collaborating with project partners Gasnor and classification society Bureau Veritas.
According to Høglund, the trials lasted for four consecutive days with hardly any downtime. After having been given the green light on both its mechanical and control equipment system, as well as its flow meters, the vessel is now already in operation.
‘The Bergen LNG conversion was both a demanding but fascinating project that was progressed and finalised in extraordinarily adverse conditions,’ said Philipp Ulrich, Høglund’s Senior Project Manager and project lead.
