ACN has become a market leader in the decommissioning market with experience of being involved decommissioning multiple platforms in the North Sea. The company recognises the real need for a structured and well-coordinated approach to the whole decommissioning process, not least because the operator requires a cost effective and cost reliable solution which complies with his legislative commitments. In order to do this, an engineered, managed and consistent approach needs to take place from the earliest point of survey to project completion.
ACN can work with the client to develop their decommissioning program starting with a FEED study onto developing the scopes right through to the offshore execution phase.
With ACN being based in Great Yarmouth on the East Coast of England this puts ACN in a prime location to support North Sea decommissioning work. ACN can also offer laydown facilities for post removal work.
