Serica Energy has developed its field development plan for the Columbus Development which provides for the supply of up to 40 million cubic feet of gas per day (gross) at peak to the UK gas market and 1,150 barrels per day (gross) of condensate and natural gas liquids.

Located in the central North Sea, the Columbus Development will be drained by a single subsea well, which will be connected to the proposed Arran-Shearwater pipeline, through which Columbus production will be exported along with Arran Field production.

When the production reaches the Shearwater platform facilities, it will be separated into gas and liquids and exported via the SEGAL line to St Fergus and Forties Pipeline System to Cruden Bay respectively.

The Oil and Gas Authority has indicated its approval of the field development plan and Columbus is targeted for start-up in Spring 2021.

Meanwhile, Sembmarine has successfully completed the fabrication of a power generation module and two bridges for the Culzean gas field located approximately 145 miles east of Aberdeen.

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

The combined weight is approximately 30,000-tonne for the integrated topsides which will 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, 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.
