April 2006 33 Golar LNG Ltd. signed a $55.6 mil- lion contract with Keppel Shipyard for what is being billed as the first ever con- version of an existing LNG carrier into a LNG Floating Storage and Regasification Unit (FSRU). Moss Maritime of Norway has prepared the conceptual specification for the FSRU and will carry out the design and engi- neering. When the conversion is com- pleted in the second quarter of 2007, it will be the first of its type in the world. Golar LNG will work with Keppel Shipyard in the engineering, procure- ment and construction for the project. The scope of work includes installation of new forward turret, side-by-side mooring system, LNG loading arms, aft thruster with compartment, a regasifica- tion plant and replacement of cargo pumps. There is also upgrading of the existing steam power electrical and marine systems. "Golar LNG has been developing this Floating Energy Solution as part of our strategy to diversify into other parts of the LNG value chain," said Graeme McDonald, group technical director of Golar LNG. "It is our belief that no other system can compete with this concept in terms of timing or pricing when satisfy- ing early or extra demand for gas. Our market survey has discovered several specific opportunities for the FSRU, however no fixed employment contract has been signed. The relative pricing differential between LNG and oil and the increased overall energy demand in SHIP SECURITY ALERT: GET READY FOR THE SECOND WAVE!
