Minimum facility platforms
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 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.
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.
BHP Billiton were extending their activities in the Gulf of Mexico, West Cameron area, a with an unmanned wellhead platform. Ramboll was awarded the design of this minimum-facility platform.
In 2010, Hess decided to expand their activities on the South Arne field with two additional wellhead platforms as part of the Phase III Development. Hess, Semco Maritime and Ramboll formed an EPC alliance to carry out brownfield work related to the project.
The Alba Field is one of the largest producers in the Gulf of Guinea. As engineering consultant, Ramboll paid a significant contribution to the development of the oil and gas field from 1997-2003.
