The PSA said on Thursday that Equinor had previously received consent to use Island Wellserver and Island Frontier vessels for well intervention activities on fields in the North, Norwegian, and Barents Sea.

According to the safety body, the consent is now extended to also cover the Trestakk and Utgard fields. The consent applies from June 27, 2019, to March 31, 2020.

Both of the Island Offshore-owned intervention vessels were built in Norway. Island Frontier was built in 2004 at the Søviknes yard and was issued an Acknowledgement of Compliance (AoC) by the PSA in October 2006.

The Island Wellserver was built in 2008 at the Aker Langsten yard and was issued an AoC in April 2009.

The vessels will be working on the Trestakk and Utgard fields in the Norwegian Sea and the North Sea, respectively.

Trestakk is located in the central part of the Norwegian Sea, 20 kilometers south of the Åsgard field. The plan for development and operation (PDO) was approved in 2017 with the development consisting 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. The field is currently under development and production is scheduled to start in 2019.

It is worth noting that the Norwegian Petroleum Directorate granted Equinor consent for start-up of the Trestakk field in May 2019.

Utgard is located in the central North Sea west of the Sleipner field center, straddling the sector boundary between Norway and the UK.

Utgard, like Trestakk, is currently under development and is scheduled to start producing at the end of 2019. It is being developed through a four-slot subsea template with two wells tied-back to the Sleipner T platform for processing and reduction of the CO2 level in the gas.
