The Oseberg Vestflanken 2 platform left Heerema Zwijndrecht
At Heerema Zwijndrecht, one of the production locations of Heerema Fabrication Group (HFG), the topside for the Oseberg Vestflanken 2 Unmanned Wellhead Platform sailed out on Sunday 25 June. The jacket followed on Monday 26 June.
In February 2016, Statoil awarded Heerema the contract for the Engineering, Procurement & Construction as well as the transport and installation of the platform. HFG carried out the engineering, based on a lean and innovative concept which was developed by HFG Engineering and Statoil in close cooperation. Fabrication started in June 2016. At the Zwijndrecht yard, HFG constructed within a year the 900 tonnes topside with a length of 25 meters, a width of 23 meters and a height of 20 meters and a 4,400 tonnes jacket with a height of 138 meters and a foot print of 36 x 36 meters. Heerema Marine Contractors (HMC) executes the transportation to the offshore location and will also perform the installation with HMC’s SSCV Hermod in the Oseberg area in the Norwegian part of the North Sea, about 130 kilometers north-west of Bergen.
“We are proud of what we have accomplished for Statoil,” says Koos-Jan van Brouwershaven, CEO of HFG. “Our design of an unmanned wellhead platform with no facilities, helicopter deck or lifeboats represents a new solution with great possibilities. It meets the challenges of lower investment costs and higher efficiency requirements. The success of this project is due to the excellent cooperation with the client and the combined strength of HFG and HMC from engineering up to and including the installation. Together with Statoil, we come to the best result in all aspects by joining forces.”
Final destination of the Oseberg Vestflanken 2 Unmanned Wellhead Platform is the Norwegian part of the North Sea, approximately 8 kilometers northwest of the Oseberg Field Centre. It is the first of three planned phases for developing the remaining reserves in the Oseberg area. The Oseberg Vestflanken Development consists of an unmanned wellhead platform with 10 well slots. Two existing subsea wells will also be reused. The well stream will be routed to the Oseberg Field Centre via a new pipeline, and the wells will be remote-controlled from the Field Centre. The field development will provide 110 million barrels of oil equivalent. Production start is scheduled for the second quarter of 2018.
Rosetti Marino S.p.A. and Heerema Fabrication Group (HFG) entered into a letter of intent on the 16th of November with the aim to sell to Rosetti Marino the HFG activities at the yard in Zwijndrecht, The Netherlands. Rosetti Marino and HFG have worked closely together and in good mutual cooperation to investigate the viability of this proposed sale.

Following a strategic review Heerema Fabrication Group (HFG) intends to divest a significant part of its activities in the field of design and fabrication of complex steel constructions for the offshore market. HFG has been struggling for some time with insufficient project volume and marginal profitability. In addition, the risks associated with building topsides are high and clients are not prepared to pay for this risk.

With the sail away on the 2nd November 2018 the jacket of the Offshore Switch Yard (OSY) platform for the Modular Offshore Grid (MOG) project is ready for installation. The jacket was built by Heerema Vlissingen, one of the production locations of Heerema Fabrication Group, for Belgium's transmission system operator Elia.
