The PSA said on Tuesday that ConocoPhillips would use the Island Constructor vessel on production licenses PL 018, PL 006, and block 2/4.

ConocoPhillips can now use the well intervention vessel on the Greater Ekofisk area until December 2024.

As for the vessel, the Island Offshore Management-operated Island Constructor, which received an Acknowledgement of Compliance (AoC) in September 2010, was built in 2008 and designed for well intervention.

The area it will be working on, named Greater Ekofisk, is located in the southern part of the North Sea, 300 kilometers southwest of Stavanger. In addition to the Ekofisk field, the area consists of the producing fields Eldfisk and Embla.

All three fields are operated by ConocoPhillips on behalf of the license partners. Ekofisk production license is located in block 2/4 on the Norwegian Continental Shelf in a water depth between 70 and 80 meters.

The total number of manned and unmanned installations that have been in operation in the Greater Ekofisk Area is close to 30.

The oldest one is from 1973 while the newest one started operation in 2015. Several of the installations are no longer in use, and many have been removed and disposed of. At the same time, the owners have invested in re-development – and the fields are prepared to be in operation for the next 40 years.

ConocoPhillips has a 35.11 percent ownership interest in the Greater Ekofisk Area, while its partners Total, Vår Energi, Equinor, and Petoro hold 39.9, 12.39, 7.6, and 5 percent, respectively.

It is worth reminding that Wintershall Dea also received consent from the PSA to use the Island Constructor vessel for well intervention activities on the Vega and Maria fields earlier this month.
