Olav Olsen calculated and calculated, Tor Ole put the drawings in my letterbox during the night and I took the first flight to Stavanger the next day to present the drawings to Shell with some verbal cost and planning estimates. I talked with Tor Ole Olsen at the Dr Techn Olav Olsen consultancy, and we agreed to create a monotower platform. We, in other words NC, could not give up that easily, so I told Shell there and then that we had a better solution and agreed to meet the company in Stavanger at 08.00 the following day. Then Shell called me – I think it was Serge Leijten – to say that they had now decided that a semi was the best option.

NC construction manager Dag N Jensen recalls the process: While Shell considered various solutions – floater, steel jacket (support structure), gravity base structure (GBS) and so forth – Norwegian Contractors (NC) promoted its concrete option.Īfter all, this construction company could point to great success during the 1970s and 1980s with its Condeep design, not least on the Statfjord and Gullfaks fields. All the options had to satisfy the same operational assumptions in terms of production capacity, wells and transport capability. This quartet was then subjected to a year of further detailing and comparison with the implementation plan, the economics of the project, general operations optimisation and key uncertainties with the proposed technology. a weather-adapted monohull production floater with possible oil storage and offloading (FPSO).a semi-submersible platform with attached storage ship.a fixed concrete platform with integrated topsides.Four options remained for further consideration in May 1986.
