BW Athena to demobilize, seeks work

The BW Athena floating production, storage and offloading (FPSO) vessel is to be demobilized from the Athena field in the UK North Sea next month.

The move, which had been expected, will the see BW Athena leave the field Athena and Anglia fields, production from which had ceased in Q4 last year and earlier this month.

First oil was achieved at the Athena oil field, in block 14/18b in the Outer Moray Firth in the North Sea in May 2012 using the FPSO. The original contract was to have the FPSO on the field from 2012-2015, but this was first extended to 2020, under an option in the contract, but then this was revised to a deal where operator Ithana Energy would pay a demobilization fee upfront and BW Offshore would have a share in cash flow from the field. Both sides then had a 60-day termination notice right.

While production ceased at Anglia, work continued to make Athena productive, with a view to ending production by the end of 2015. The net daily production capacity of the two fields was about 1000 b/d. According to BW Offshore, the BW Athena, on which the firm is duty holder, has had an uptime of 98% since first oil. 

The turret-moored unit has 28,000 bbl/d production capacity, 25,000 bbl/d water injection capacity, 50,000 bbl storage capacity. The BW Athena, formerly BW Carmen, was built in 1994 and was converted into an FPSO in 1999. The FPSO is now being marketed for new opportunities.

Meanwhile, BW Offshore has received a one year contract extension for the lease and operation of the FPSO Umuroa. The FPSO is operating on the Umuroa field offshore New Zealand for AWE. The firm period has been extended to Q4 2017 (from Q4 2016).
