The unit, formerly the 138,830-cbm LNG carrier Golar Frost, has been under conversion since June 2009 at Drydocks world Dubai yard for contractor Saipem and owner OLT. The LNG Carrier, built by Hyundai Heavy Industries was converted into a floating LNG receiving terminal of the FSRU type, and will be permanently moored off Livorno, Italy and connected to shore through a gas export pipeline. There are only a few such units in operation around the world.
The unit has a net storage capacity of 137,100 m3 and it is classed as a marine unit designed to remain at the site for 20 years. The FSRU has a steel mono-hull with four Moss-type LNG tanks, the Re-gasification Plant is located at the forward end and the accommodation with central control room and utility machinery is at the aft end.
The project consisted of constructing, installing and commissioning various components such as the Turret mooring system, side by side berthing mooring system for LNG carrier, LNG storage tanks and loading system, LNG transfer system to re-gasification plant, process plant for re-gasification, boil-off gas handling and gas send-out to Export System, metering systems, utilities including power generation and sea water systems, control, automation and communications systems, gas flexible risers and riser base and control umbilical from FSRU.
“Floating Storage Re-gasification Units have been a key contributor towards developing new markets for LNG and provide vital links for a new market,” said HE Khamis Juma Buamin, Chairman of Drydocks World and Maritime World.
“They offer flexibility, are accepted technically and are attractive from an economic point of view – all of which are significant factors for the development of the market. Such conversions involve a high level of sophistication and a wide-range of technical and commercial skills. We are delighted that our shipyard was able to offer these and was able to conclude complex tasks safely, efficiently and to the satisfaction of our client.”
