NGI is a key contributor to the offshore industry. Our strategy is to be in the forefront of the technological development, and our services are used worldwide.
NGI is an important contributor to the development of offshore oil and gas fields and wind energy. Internationally recognized expertise within geotechnics, geology, geophysics and monitoring places NGI in a unique position to enhance recovery, reduce cost and mitigate risk.
NGI offers a wide variety of services to the offshore industry, and about 40% of NGI's total turnover is for the offshore oil and gas market. Our clients are the major international oil companies, their contractors and suppliers. NGI provides state-of-the-art expertise within offshore site investigations, foundation design, numerical modelling, petroleum geomechanics, subsea technology and instrumentation and monitoring.
NGI offers services to the oil and gas industry within exploration, development, operation and decommissioning of offshore fields. Our experience in offshore geotechnics is now key to the current large wind power development projects in Northern Europe.

Detailed list of oil and gas services offered by NGI
NGI is internationally recognised for its offshore geotechnical expertise. New methods and equipment for investigating the characteristics of the underground has always been one of NGI's focus areas.
Our experts can predict the behaviour of soil when exposed to cyclic loading from waves and wind on platforms and other offshore structures.
NGI gained international recognition with the development of marine EM (electromagnetic) and shear wave technology, which is used for instance for hydrocarbon exploration and surveillance of the subgrade sediments.
NGI has been a central actor in foundation engineering of the large gravity base platforms at the Statfjord, Gullfaks and Troll fields in the North Sea and the Hibernia field offshore eastern Canada, to name a few examples. Development of the suction anchor technology also required NGI's committed involvement. Today, this type of foundation is widely used for anchoring and for the foundation of offshore installations.
NGI was one of the pioneers in the evaluation of the risk associated with offshore geohazards, such as earthquakes, submarine slides and seepage of gas in the seabed sediments. Our expertise is the understanding of the mechanisms which may lead to an unstable seabed, the modelling of large mass movements and slides, and the quantification of uncertainties, hazard and risk.
Advancing the geosciences
NGI has co-ordinated a number of research programs for the oil industry, and cooperates with research organisations around the world. Today, NGI is actively working to develop new technology for the future. For example we participate in several R&D projects to find suitable areas and safe techniques for the storage of CO2 gas, and methods to monitor future repositories.
The deposition of CO2 in the underground in abandoned reservoirs should provide a solution to prevent spreading of CO2 in the atmosphere and thereby contribute to solve the challenges related to climate change.
