Canada-based Robert Allan Ltd. was selected by Teekay Shipping (Canada) Ltd. to provide the contract engineering package for the conversion of the M/V Navion Clipper from a shuttle tanker into a Floating Storage and Offloading (FSO) unit.
Teekay Offshore Partners LLP, a subsidiary of Teekay Corporation, was awarded a contract in 2013 to supply an FSO unit to the Bualuang Field in the Gulf of Thailand. The contract is for a 10-year charter, with extension options. The oilfield is operated by Salamander Energy and has been in production at this site since 2008.
The scope of work from Robert Allan Ltd. includes the design of the crude oil export and import systems (turret design and supply by London Marine Consultants), a new helideck capable of landing a Sikorsky S61N helicopter, accommodation and systems modifications to suit an increased crew complement, produced water-handling and delivery systems, materials handling systems, offshore crane support structures, upgrades to the fire and foam system and safety systems, and on-going construction support services.
The FSO System is designed to stay continuously moored on site for an initial period of up to fifteen (15) years without dry-docking, and to withstand the 100-year storm environmental criteria.
With a storage capacity of 480,000 barrels, the FSO will be capable of accommodating peak production throughput of 20,000 barrels per day of Bualuang crude oil, while discharging at the rate of 20,000 barrels per hour simultaneously to a tanker from a stern-mounted offloading hose. It will have dedicated settling tanks and storage tanks.
The FSO will be moored by an external turret Single Point Mooring (SPM) with weathervane capability through 360°. Crude oil will be delivered to the FSO through a riser at rates up to 20,000 barrels per day.
The 228.9 m long M/V Navion Clipper is currently undergoing conversion work at Yui Lian Dockyards Limited in Shekou, China. The FSO is expected to be in operation in the Gulf of Thailand in 2014.
