Fred. Olsen Windcarrier said on Tuesday that the work for Perenco UK was done at the Tyne and Guinevere installations in the Southern North Sea using the jack-up vessel Blue Tern.

The work started in December 2019 and was completed during the second week of January 2020. It consisted of lifting of the two topside and jacket structures onto Blue Tern deck and the associated cutting, rigging, and seafastening works.

The Blue Tern arrived at the Hoondert disposal facility in Vlissingen, Holland on January 13, where the platform structures were offloaded, and the actual disposal and recycling would take place.

The company added that the work was done in close cooperation with Ardent, which was responsible for planning and engineering of the cutting, lifting, seafastening, and offloading works, while Fred. Olsen Windcarrier was responsible for vessel operation and overall management of the project.

Henrik Mork, head of project execution at Fred. Olsen Windcarrier, said: “This is the first oil and gas decommissioning work done by Fred. Olsen Windcarrier, and represents a new market segment for us.”

According to Fred. Olsen, the work was done under challenging weather conditions during wintertime, but still within the overall time schedule for the project.

The Tyne field – located approximately 188 kilometers off the coast of Norfolk – was discovered in 1992 and production started in 1996. Production ceased in November 2015.

The Guinevere field – located some 60 kilometers north of the Bacton terminal and 56 kilometers east of the Theddlethorpe gas terminal – was discovered in 1988 and started production in 1993. Production ceased in May 2017.

It is worth reminding that Perenco submitted its draft decommissioning program for Tyne and Guinevere installations to the UK authorities back in July 2018. Perenco received approval for the decommissioning programs in January 2019.
