The contract involves a combined weight of 33,000 tonnes, as well as options for another 5,000 tonnes.

The assignment will at peak provide work for around 100 persons. Kvaerner said on Tuesday.

The Aker BP-operated Valhall and Hod fields have since production started in 1982 produced more than one billion barrels of oil equivalents. After the new production and accommodation platform came in 2013, some of the oil installations will be removed.

Kvaerner has already started the decommissioning of the old Valhall accommodation platform but has now been awarded additional removal work on the field.

Aker BP has given Allseas, with Kvaerner as a subcontractor, the assignment to remove and decommission the drilling platform and the production platform from the Valhall field, in addition to the unmanned Hod platform that is connected to Valhall.

The project also includes three jackets and four bridges.

The structures will be removed from the field by Allseas, and delivered to Kvaerner’s decommissioning facilities at Stord where they will be dismantled and recycled.

The first structures are expected to arrive Stord in 2022. The drilling platform, the process platform and one jacket from the Valhall field will be delivered first, while Hod and the remaining structures are planned to arrive in 2025.

The method work will begin later this year, while detail offshore mapping and engineering work will start in 2021.

Magnus Kise, SVP decommissioning projects in Kvaerner, said: “In this project, we will also utilise a newly developed automatic cutting machine for pipes and beams, which will reduce the need for manual work significantly and thus reduce risk.

Combined, these measures enable us to handle these types of projects in a safe manner”.

In related news, Kvaerner has recently been awarded a contract for delivering the topside and steel substructure for the new, unmanned wellhead platform at the Hod field.

Aker BP has also recently submitted its plans for development and operation for the Hod project to the country’s Ministry of Petroleum and Energy.

The original Hod platform was the first unmanned platform on the Norwegian continental shelf when it started production in 1990.

First oil from the new Hod platform – which will be named Hod B – is planned for the first quarter of 2022.
