Modifications & maintenance

To keep mature fields pumping in times of dwindling reservoirs and to keep infrastructure in shape, modifications and brownfield engineering are necessary, everyday aspects of the petroleum industry. Brownfield engineering ranges from system upgrades and debottlenecking to integrity management and lifetime extension.

Experts on modifications and lifetime extension

Ramboll carries out a variety of brownfield modification projects on-shore as well as offshore, ranging from minor modifications to complete revamps. Our system upgrades and debottlenecking projects optimise production, while our reassessments ensure structural integrity and enable lifetime extension.

We have a strong focus on keeping shutdown time to a minimum and all refurbishment work on schedule, which is why we offer precision 3D laser scanning & survey as a basis for all our modification projects.

Rectification of GRE piping systems at Al Shaheen

Maersk Oil Qatar operates the Al Shaheen field located 180 kilometres off the North East coast of Qatar in the Arabian Gulf. First oil was produced in 1994, and since then the field has undergone tremendous development with modification works and new designs still taking place on a continuous basis.

South Arne platform

South Arne Phase III - Tie-in of two additional wellhead platforms

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.

Tyra East Rationalisation Project

The Tyra Field is the largest gas field in the Danish North Sea sector – it is operated by Maersk Oil, and has been producing since 1984. Ramboll has been part of the Tyra East Rationalisation Project; just one phase in a series of Optimisation Projects in the field.

We have recently completed one of our most extensive projects to date for Maersk Oil Qatar on the offshore field development project called Al Shaheen.

Amazing Al Shaheen

Al Shaheen is a production oil and gas field off the North East coast of Qatar in the Arabian Gulf. The oil field lies over the North Gas Field; the largest gas field in the world. Al Shaheen has been developed by Maersk Oil in what constitutes one of the largest and most complex offshore oil and gas projects undertaken in the world today.

LNG vessel

Upgrade of LNG berth at Ras Laffan in Qatar

Ras Laffan is the centre of LNG and GTL activities in Qatar and the port is considered one of the largest LNG export facilities in the world.

Ramboll Oil & Gas undertook the detailed engineering for an upgrade of the LNG berth at Ras Laffan during 2009 and 2010.

Cutting carbon footprints - flare gas recovery on South Arne

Hydrocarbon emissions from platforms and refineries are a source of atmospheric pollution, and there is a strong drive in the industry to find environment-friendly solutions. Ramboll Oil & Gas has considerable experience in this field, and recently we completed the design of a flare gas recovery system for the North Sea platform, South Arne operated by Hess Denmark.
