UK-based upstream oil and gas player Serica Energy is engaged in talks with Dana Petroleum to come up with a way to improve the performance of a floating production, storage, and offloading (FPSO) vessel, which is being prepared to resume limited production from Serica’s North Sea asset on the UK Continental Shelf (UKCS).

Following a notification from Dana Petroleum, as the operator of the FPSO Triton , about a temporary reduction in production while further maintenance was underway, the subsea intervention work on the Bittern field was moved to November 2025.
