Реферат: Method and structures perform decommissioning of offshore oil and gas platforms with associated wells. By installing on a platform (1) a movable decommissioning rig tower (2) but stripping away most of the other structures and equipment on the platform (1), and specifically not providing supporting resources such as drilling mud and power, accommodation, etc. on the platform, it is possible for both the rig tower (2) and a further rig tower (28) installed on a jack up rig (20) located alongside the platform (1) to access the well bay (5) of the platform. Thereby, two wells may be accessed simultaneously through the same well bay (5) and respective decommissioning operations carried out simultaneously and independently.
