The vessel which will be used for the massive North Sea Culzean gas field has been officially named.
A ceremony was held near Singapore on Wednesday for the Ailsa FSO.
Construction was completed for the vessel last week, which is designed with a 40-year hull lifespan.
It can operate continually without drydocking for 25 years and can store up to 430,000 barrels of condensate at a time.
Culzean is operated by French energy giant Total, which gained a 49.99% stake in the project when it took over Maersk Oil earlier this year.
The project, due to come online next year, is expected to pump out enough gas to meet 5% of total UK demand when it hits peak production in 2020/2021.
In a social media post, Lars Banke, the FSO site and engineering manager for Culzean development with Total said: “Finally, we have named our FSO Ailsa.
“A great naming ceremony at Tuas in company of the executive management and projects teams from MODEC, SCM and Total as well as our Culzean partners.
“As much as we will miss the shipyard and our colleagues out here, now we all just want finish the very last scope and get the FSO en route to UK. Which shall happen very soon.”
