Hyundai Samho Heavy Industries (HSHI), a shipbuilding affiliate of Hyundai Heavy Industries, the world’s biggest shipbuilder, successfully launched a 162,000 m3 LNG carrier built using the on-ground shipbuilding method. This marked the first use of this Hyundai-developed method to a that type of ship.

The LNG vessel was ordered by Golar of Norway in February, 2012. Measuring 289.0 m in length, 45.6 m in width, and 26.0 m in depth, the ship is scheduled to be handed over to the owner by late July 2014 after outfitting and painting work.
After the ship, with about 270 large blocks, LNG containment system, and propulsion system, is assembled in the on-land shipbuilding area equipped with a 1,200-tonne 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.
Balancing the LNG carrier, which is about 30% heavier than other types of ships, on the hydraulic skidding facility and on the floating dock is the critical point of launching.
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.
HSHI says that the on-ground shipbuilding method allows higher productivity and cost effectiveness, facilitates efficient utilization of yard facilities and resources, and improves the safety of working conditions. Hyundai Samho Heavy Industries plans to build 10 of 12 LNG carriers in its order book using this method.
