Offshore Concrete Structures

Multiconsult is one of the major companies in Norway performing design and engineering of offshore concrete structures for the oil and gas industry. Multiconsult has been involved in most of the gravity based and floating concrete structures for the last 40 years.

Concrete structures have proven well suited for development of offshore oil and gas fields. Despite operating in the most hostile offshore environments with extreme waves, earthquakes, ice loads  and water pressures, these structures are almost maintenance free. A large portion of the offshore concrete structures has been developed, planned and built by Kvaerner. A Norwegian offshore concrete industry was developed with key competence covering all aspects of such projects. As part of this industry, Multiconsult has been heavily involved in the design of offshore concrete structures for more than 40 years, particularly as a close ally to Kvaerner.

Multiconsult can offer services within all actual phases and disciplines required for engineering of offshore concrete structures.
