In a world first, Hyundai Samho Heavy Industries (HSHI), a shipbuilding affiliate of Hyundai Heavy Industries (HHI), has announced the successful launch of a 162 000 m3 LNG carrier built using the on-ground shipbuilding method.
The LNG carrier was ordered by Golar in February 2012. The LNG carrier is scheduled to be handed over to the owner by late July 2014 after outfitting and painting work.
Approximately 270 large blocks, an LNG containment system, an engine and a propeller were manufactured and assembled in the on-land shipbuilding area, which is equipped with a 1200 t gantry crane, four jib cranes and a floating dock. The assembled LNG carrier is loaded out onto a floating dock by hydraulic skidding. The LNG ship is then launched out by submerging the floating dock.
The LNG carrier is about 30% heavier than other types of ships, so it is essential that there is a balance on the hydraulic skidding facility and on the floating dock.
Though this is the first LNG carrier Hyundai Samho has built using the on-ground method, the company has already built 50 other ships using this method since May 2008.
The on-ground shipbuilding method allows higher productivity and cost effectiveness. It also facilitates efficient utilisation of yard facilities and resources, and improves the safety of working conditions. Hyundai Samho Heavy Industries plans to build 10 of 12 LNG carriers currently in its order book using this on-ground method.
