The topside and jacket for the Oseberg Vestflanken 2 unmanned wellhead platform set sail on 25 and 26 June respectively from Heerema Fabrication Group’s (HFG) Heerema Zwijndrecht yard in the Netherlands.
The platform and jacket will be installed at Statoil’s Oseberg field in the Norwegian North Sea, approximately 130km northwest of Bergen, Norway.
Statoil in February 2016 awarded HFG the contract for the engineering, procurement, construction, transportion 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.
In June 2016, HFG started fabrication of the 900 tonnes topside, which is 25m long, 23m wide and 20m high, and the 138m high, 4,400 tonnes jacket, which has a footprint of 36m by 36m.
Heerema Marine Contractors (HMC) is transporting the platform and jacket to the offshore location, and will install both using HMC’s SSCV Hermod approximately eight km northwest of the Oseberg field center.
The installation marks the first 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’s center, HFG said. The field development will provide 110mmboe. Production start is scheduled for Q2 2018.
“We are proud of what we have accomplished for Statoil,” said Koos-Jan van Brouwershaven, CEO of HFG, in a 26 June press statement. “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.”
