The unmanned wellhead platform is a development concept under consideration for several licenses on the Norwegian continental shelf. Ramboll carried out a study for The Norwegian Petroleum Directorate pointing out pros and cons of the concept.
Ramboll has assisted DONG Energy with a development project for modification of the Siri field in the North Sea, where we designed two lightweight and robust minimum-facility platforms, Nini and Cecilie.The two unmanned wellhead platforms operate as satellites tied back to the mother platform, Siri, via three inter-field pipelines. The water depth is approximately 60 metres.
The lifetime extension of the oldest oil field in the Danish North Sea marked one of the most challenging and complex offshore campaigns initiated by Maersk Oil. The goal of the project as a whole was to extend the lifetime of Dan Bravo until 2042.
In 2012 the Danish National Advanced Technology Foundation announced its financial contribution to a research project conducted by Aalborg University and endorsed by Maersk Oil and Ramboll Oil & Gas. The project tackles the problem of oil recovery by looking into ways of ensuring a higher productivity and less oil in the produced water.
ConocoPhillips awarded Ramboll a conceptual design study update for an unmanned stand-alone minimum-facility wellhead platform in the Greater Ekofisk Area.
As part of the development of the Valhall field, BP commissioned Ramboll and alliance partners Heerema Tønsberg and IV Oil & Gas to engineer, construct and install two unmanned wellhead platforms at Valhall Flank.
In 2010 DONG Energy made an interesting oil find in the Danish North Sea, in the Solsort Prospect. An extensive data collection programme was carried out, and subsequently Ramboll assisted on a number of studies to assess the feasibility in developing the asset.
