This paper describes the operator’s culture of circular decommissioning, with the main goal to improve environmental performance by implementing circular-economy principles during the engineering and execution of decommissioning projects.
-
This paper presents how one operator has developed a culture of circular decommissioning with the main goal of setting up a structured process to improve environmental performance by implementing the principles of a circular economy during decommissioning.
