Two barges left Lowestoft quayside over the weekend containing a power generation module and two bridges, built by the town’s Sembmarine SLP Ltd. The barges were headed for the Culzean Gas Field, 145 miles east of Aberdeen in the UK sector of the Central North Sea.

The Culzean development comprises of a well head platform, a utilities and living quarters and a central processing facility.

The weight of the integrated topsides is approximately 30,000-tonnes, and is built to handle up to 500 million standard cubic feet per day (MMSCFD) of gas and 25,000 barrels per day (bpd) of condensate.

Operated by Total E&P UK, the field is the largest gas field sanctioned by the UK since East Brae in 1990 and has the potential to meet around 5% of UK gas demand by 2020/21.
