Apr. 2013 - First oil has been achieved at the Huntington field in the UK North Sea. After an initial ramp-up period, the field is expected to produce at a rate of 30,000 bopd. Huntington has been developed with six subsea wells and the Sevan Marine-designed Voyageur Spirit floating production, storage and offloading (FPSO) vessel. The field was discovered in 2007 and the UK Department of Energy and Climate Change approved the plan of development at the end of 2010. E.ON (25%) operates the field on behalf of its partners Premier (40%), Iona Energy (15%) and Noreco (20%).

Jan. 2013 - Production startup at the Huntington field is on track to commence in the first quarter of 2013.

All that remains is to hook up and test the subsea production equipment and finish commissioning of the FPSO.

Nov. 2012 - The Voyageur Spirit FPSO has been on location at the Huntington field in block 22/14b in the UK North Sea since early October undergoing hook-up of risers and completion of commissioning.

Prior to being towed to location, the Voyageur Spirit underwent upgrades at the Nymo shipyard in Norway to prepare for Huntington.

May. 2012 - E.ON reported that progress has been made offshore on the Huntington field in the UK sector of the North Sea.

Previously announced delays to the upgrade of the FPSO have been addressed by increasing the manpower in the yard. The operator continues to forecast fourth quarter for first oil with an expected plateau production rate of 25,000 bopd.

Feb. 2012 - Noreco, a partner in the Huntington field, reported that drilling of the development wells continued on the field through 4Q 2011 with the jackup ENSCO 100 (350'ILC) according to plan.
