FSO AILSA: FIRST FSO WITH 40-YEAR LIFESPAN HULL

FSO Ailsa, the world’s first Floating Storage and Offloading (FSO) vessel with a 40-year hull lifespan, will set sail next month for the Culzean gas field in the UK North Sea.
Newly completed at the Sembcorp Marine Tuas Boulevard Yard for MODEC, a leading specialist of offshore oil and gas floating production systems, and with French oil supermajor TOTAL as the field operator and TOTAL, BP and JX Nippon as Joint Venture owners, FSO Ailsa will enter service with a hull designed to have twice the average hull fatigue lifespan of other newbuild FSOs, as verified by marine assurance company DNV GL.
A longer hull fatigue life enables ships to withstand harsher and more extreme environmental conditions, such as rogue waves, corrosion, large ambient temperature variation and thunderstorms.
Sembcorp Marine President & CEO Mr Wong Weng Sun said the Group had strengthened its capabilities and production capacity over the past few years, aiming to pack more value into its solutions. He said, “Providing more competitive customer value is what drives Sembcorp Marine to invest strategically in capability and capacity expansion. The successful completion of FSO Ailsa demonstrates that we are now supporting the energy, offshore and marine value chain with a broader and deeper suite of innovative solutions. We are grateful for the opportunities to contribute to the Culzean field development, not only through the FSO project, but also our construction of three major fixed platform topsides comprising central processing, wellhead as well as utility and living quarters facilities which we will deliver in the weeks ahead.”
Equipped with a 430,000-barrel condensate storage capacity, FSO Ailsa also boasts a 25-year continuous operability without drydocking and full compliance with strict UK safety regulations for harsh-environment operations in the Culzean field.
FSO Ailsa is Sembcorp Marine’s first floating storage and offloading newbuild project, constructed over 22 months with a zero Lost Time Incidents record. The Group designed this vessel in-house, particularly leveraging a proprietary hull design from its subsidiary LMG Marin, a leading ship design house in Europe. (Source: Sembcorp Marine)
