Two onboard LNG regasification plant installations of Hamworthy plc, Poole, are to undergo gas trials this summer, one on a floating storage and regasification unit (FSRU) for Brazil, the other on a shuttle regasification vessel (SRV) destined for the US.
In July 2007 Hamworthy signed a contract with Golar LNG for a system comprising three LNG regasification skids to be retrofitted on the 2004-built LNG carrier "Golar Winter", being converted into an LNG floating storage and regasification unit (FSRU) by Keppel Shipyard in Singapore. Chartered by Petrobras, the vessel will shortly be heading for Brazil to play its part in an LNG import project located in Guanabara Bay, where gas will be sent from Golar Winter to an onshore gas grid.
Hamworthy delivered the three propane re-gasification skids at the end of 2008. Capacity per skid is 7 million cum/day; outlet pressure is 103 bar and outlet temperature up to 6°C. Two skids will be used during nominal send-out while the third is on stand-by.Each skid contains the required pumps, motors, heat exchangers, instrumentation and control systems to provide the required capacity. The equipment is designed for marine installations and cryogenic working conditions and can handle large variations in send-out capacity. Only proven equipment with extensive references is included in the delivery.
"Golar Winter’s" plant was the second system. Hamworthy delivered the first plant to site last summer. This onboard vaporiser system was for installation on the LNG shuttle regasification vessel (SRV) "Suez Neptune". SRVs are designed to transport and store LNG, and then vaporise it into natural gas that can be sent ashore by subsea pipeline. "Suez Neptune" is the first of two SRVs ordered from Samsung in South Korea for Höegh LNG to serve the Neptune terminal in Boston, Massachusetts. Gas trials are scheduled for August 2009. Hamworthy is supplying three regasification skids per ship. Each ship set will have a regasification capacity of 210 tonnes/hr of LNG with a send-out pressure of 115 bar. Gas trials will be taking place on the second Neptune SRV, Suez Cape Ann, in June 2010.
Hamworthy’s third regasification project is for the FSRU "Golar Freeze" for Dubai Supply Authority (DUSUP) and Shell in Dubai; Hamworthy is delivering the regasification skids for this vessel in September 2009. The system will be installed on the 1977-built LNG carrier that is being converted into an FSRU before being time chartered by Dubai Supply Authority (DUSUP) for 10 years, with options to extend for up to another five years.
After its delivery to DUSUP in the second quarter of 2010, "Golar Freeze" will be permanently moored alongside a purpose-built jetty within the existing Jebel Ali port. The FSRU will be capable of storing 125,000 cum of LNG and delivering up to 14 million m3/day (about 3 MTA) of regasified LNG to DUSUP for further delivery into the Dubai gas network. As DUSUP's adviser, Shell has worked closely with Golar LNG in the development of this project.
