Equinor has previously received consent to use Island Wellserver and Island Frontier for well intervention activities on fields in the North Sea, Norwegian Sea and Barents Sea. The consent has now been extended to also cover the Trestakk and Utgard fields.
The consent applies from 27 June 2019 to 31 March 2020.
The two facilities are owned by Island Offshore, whose head offices are in Ulsteinvik.
Island Frontier was built in 2004 at the Søviknes yard. It is registered in Norway and classified by DNV-GL. Island Frontier was issued with an Acknowledgement of Compliance (AoC) by the PSA in October 2006.
Island Wellserver was built in 2008 at the Aker Langsten yard. It is registered in Norway and classified by DNV-GL. Island Wellserver was issued with an Acknowledgement of Compliance (AoC) by the PSA in April 2009.
Trestakk is a field in the central part of the Norwegian Sea, 20 kilometres south of the Åsgard field. The water depth is 300 metres. Trestakk was proven in 1986 and the plan for development and operation (PDO) was approved in 2017. The development concept consists of one subsea template with four well slots and an additional satellite well. The subsea installation will be tied-back to the Åsgard A facility for processing and gas injection.
Production started in 2019.
The Utgard field is in the central North Sea, straddling the sector boundary between Norway and the UK. It is located 20 kilometres west of the Sleipner field centre. The water depth is 110-120 metres. Utgard was discovered in 1982 and the plan for development and operation (PDO) was approved in 2017. The development concept is a 4-slot subsea template with two wells tied-back to the Sleipner T facility for processing and reduction of the CO2 level in the gas.
The field is under development, and production is scheduled to start in 2019.
