The beginning

Ross Offshore AS was established in 1997 by Vidar Stener Ingebretsen and Tor Aanderud Larsen, to provide consultancy services within drilling, completion and subsea.

In less than 10 years the company has grown to more than 100 consultants delivering a wide range of services to the O&G. Ross Offshore now have several working frame agreements with major operators within D&W, Subsea and associated O&G upstream services.

Project based business areas

In 2007 a new business area was established within Drilling & Well Management, followed by Field Development in 2008. These new business areas where created to offer project based services to the O&G business utilizing the strength of the established senior consultancy network. In 2008 Ross Offshore was awarded the Subsurface scope of work on the Gassnova CCS project.

Change in ownership

In 2008, Ross Offshore AS joined the Subsea Technology Group, part of Hitech Vision fund IV. The group was a substantial supplier of subsea, drilling, well intervention, field life cycle services and products to the upstream oil and gas industry. In 2011 the majority owner decided to sell Poseidon and Bennex, and later Altra. To increase the effort towards the D&W market an acquisition/merger with Odfjell Well Management was concluded in summer 2011. The combined company is now a significant player within D&W, resource management, CO₂ storage and early phase field development on the NCS.
