Oseberg Vestflanken 2 Platform Leaves 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 EPC 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 900t topside with a length of 25m, a width of 23m and a height of 20m and a 4,400t jacket with a height of 138m and a footprint of 36m x 36m.
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.”
Final destination of the Oseberg Vestflanken 2 Unmanned Wellhead Platform is the Norwegian part of the North Sea, approximately 8km 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 ten 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 Q2-2018.
