Removing a piece of equipment from action (such as removing all the infrastructure after its has passed its life span for instance removing wells from the sea-floor after a field has been depleted). It is the preferred term (rather than Abandonment) for the re-use, recycling and disposal of redundant oil and gas facilities. In nuclear power it is also the removal of a facility (e.g. reactor) from service, also the subsequent actions of safe storage, dismantling and making the site available for unrestricted use
