Once a well has been plugged and abandoned and associated assets connected have no alternative use, infrastructure must also be abandoned and depending on developments in legislation either completely removed or otherwise made safe.

There are many similarities between the installation of an asset and its removal. It requires the same activities to be performed, however, with the additional challenge that parameters have changed compared to the moment of installation. Furthermore, the associated costs are considerable which in today’s climate does pose an additional strain on the operator’s financial position.

With a pragmatic hands-on approach and experience, handling the potential risks resulting from the many uncertainties associated with abandonment and decommissioning can be controlled.

Decommissioning for an Offshore Pipeline System

Northern North Sea, United Kingdom

The Ninian oil field was brought on-stream in 1978, and is one of the oldest oil fields in the North Sea. It was operated using three fixed platforms: Ninian North, Ninian South, and Ninian Central – a hub which also supports the operation of nearby fields. In 2016 CNR looked to decommission the Ninian North platform, and the pipeline system connecting it to Ninian Central. IRM Systems project managed the operation from the FEED stage, engagement with third-party service providers, to cleaning and decommissioning of the pipeline. Read more.
