“…The heart of the LNG facility, the liquefaction plant, is borne and operated on a gas liquefaction barge, which was constructed at the Spanish shipyard group Izar Construcciones Naval (Dragados yard) in Cadiz. The barge construction contract was worth an estimated NOK170 million.
The process barge measures 9m H × 154m L × 54m W. This process barge approach was chosen as it greatly reduces the need for steelwork on Melkøya Island, necessitates a compact efficient design, allows prefabrication of modular components off-site in a convenient dry-dock situation and, most importantly, gives cost savings as well as higher productivity compared with constructing the plant on-site.
Following completion of the barge in May 2005 it was towed to an outfitting yard where 24,000t of process equipment for the gas liquefaction plant was installed on the deck. The barge was then transported to Melkøya Island in July 2005 on a heavy-lift vessel [Dockwise BV] and installed in a custom built dock. The completion work for the barge on the island was completed by the end of August 2006….”
