Statoil has awarded Heerema the contract for the Engineering, Procurement & Construction (EPC) of the unmanned wellhead platform at Oseberg Vestflanken 2, as well as the transport and installation of the platform.
Heerema Fabrication Group (HFG) will carry out the engineering, procurement and construction of the unmanned wellhead platform and Heerema Marine Contractors (HMC) will be responsible for the transport and installation of the platform.
Unmanned Wellhead
Fabrication of the platform will start in June this year and the sail away is scheduled for summer 2017, followed by installation with HMC’s Semi Submersible Crane Vessel. The unmanned wellhead platform will have no facilities, helicopter deck or lifeboats thereby reducing investment costs. The platform will be built at Heerema's Zwijndrecht yard.
Oseberg Vestflanken 2
The Oseberg Vestflanken 2 platform will be installed in the Norwegian part of the North Sea at a water depth up to 110 metres and approximately 8 kilometres northwest of the Oseberg Field Centre. The topside will measure 25 x 23 metres, has a height of 20 metres and will weigh 900 tonnes. The jacket will have a height of 138 metres with a footprint of 36 x 36 metres and a weight of approximately 4400 tonnes. Special to the jacket are suction buckets instead of piles.
Oseberg Vestflanken 2 is the first of three planned phases for developing the remaining reserves in the Oseberg area, about 130 kilometres northwest of Bergen. The Oseberg Vestflanken Development will consist of an unmanned wellhead platform with ten well slots. Two existing subsea wells will also be reused. All wells will be drilled by a jack up Cat-J drilling rig. 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.
