LMC is a leading designer of turret mooring systems. One internal, and eleven external turrets have been designed by LMC to date, with two more systems currently under development.
Suksan Salamander FSO, Bualuang Field
The Bualuang oilfield, situated offshore Thailand, is operated by Salamander Energy and has been producing since 2008. Early in 2013, LMC was awarded an EPC contract by Teekay Offshore for supply of the Turret and Mooring System for the Suksan Salamander FSO. LMC scope also comprised geotechnical survey investigation, site metocean data assessment, and vessel integration design. In addition, LMC designed and supplied the complete process swivel assembly, with an electrical slip ring provided to LMC specification.
The Suksan Salamander FSO is permanently moored by an LMC external cantilever turret, allowing the vessel to weathervane 360 degrees in 60m water depth. The riser system comprises one export water (6”), one import production (6”) and a spare production (6”) riser. The FSO storage capacity is 480,000 barrels with peak production at the rate of 20,000 barrels per day.
The turret is designed ABS class, and to withstand a maximum environmental condition of 7.5m significant wave height. The unit is initially designed for 15 years’ service life without dry-docking.
The turret was fabricated in the EMAS-owned SOFEL shipyard in Vietnam, and delivered to the vessel conversion yard in China at the end of 2013 for integration on to the FSO early in 2014.
The Suksan Salamander FSO was installed at the Bualuang field in mid-2014, and has been producing successfully since then.
