Statoil has received consent from the Petroleum Safety Authority (PSA) Norway to use Island Frontier for preparatory well-plugging work at Statfjord Øst and Sleipner Øst in the North Sea.
Statoil has received consent to use Island Frontier, which is a well-intervention vessel, for work preparatory to subsequent permanent plugging of four wells, two at Statfjord Øst and two at Sleipner Øst. These wells are 33/9-M-1 AH, 33/9-K-2 H, 15/9-D-1 H and 15/9-D-3 H.
Statfjord Øst is an oilfield located around seven kilometers north-east of the Statfjord field in the northern part of the North Sea. The field has been developed using three subsea templates tied back to the Statfjord C platform.
Sleipner Øst is a gas-condensate field in the central North Sea. The field has been developed using an integrated processing, drilling and accommodation platform with a gravity base structure and associated subsea templates.
Island Frontier is a riserless well intervention vessel that provides access to the subsea well through a Well Control Package.
Island Frontier was built at Søviknes Verft AS in 2004. It is 106 metres long, with a beam of 21 metres. The vessel is registered in Norway and is classified by DNV GL. It was issued with an Acknowledgement of Compliance (AoC) by the PSA in October 2006.
