PHOTO: Heerema loads out Oseberg Vestflanken jacket

Heerema Fabrication Group (HFG), the Netherlands-based manufacturer of large structures for the oil and gas industry, posted a photo on social media on Tuesday showing the load out of the jacket for Statoil’s Oseberg Vestflanken 2 project.

In a caption accompanying the photo, the company said that the jacket was loaded out in its Zwijndrecht yard and that the topside load out would follow soon.

When completed and shipped out, an unmanned wellhead platform (UWP) will be mounted onto the jacket.

To remind, Heerema signed the contract with Statoil for the engineering, procurement & construction (EPC) as well as the transport and installation of the UWP platform for the Oseberg Vestflanken 2 project in February of last year.

It was agreed for Heerema Fabrication Group to carry out the EPC part of the work and Heerema Marine Contractors (HMC) to be responsible for the transport and installation of the platform.

Norway’s Ministry of Petroleum and Energy approved Statoil’s Plan of Development and Operation (PDO) of Oseberg Vestflanken 2 in June 2016 and the steel cutting ceremony for the UWP was held only days later.

Although HFG did not state the dimensions of the loaded jacket, initial specs claimed that it would be 138 meters high with a footprint of 36 x 36 meters and a weight of approximately 4,400 tonnes. The topside will measure 25 x 23 meters, have a height of 20 meters, and will weigh 900 tonnes.

The Oseberg Vestflanken 2 jacket and platform will be installed in the Norwegian part of the North Sea at a water depth up to 110 meters and approximately 8 kilometers northwest of the Oseberg Field Centre.

Oseberg Vestflanken 2 is the first of three planned phases for developing the remaining reserves in the Oseberg area, about 130 kilometers northwest of Bergen. Production start is scheduled for the second quarter of 2018.
