REFITTING PLATFORMS DUE FOR DECOMMISSIONING IN SUSTAINABLE PROJECTS

The reuse of oil platforms remains a problem that does not yet have a solution, except for either removing or completely restoring them. This is especially true for offshore rigs in the Mediterranean and generally for the Gulf of Mexico and the North Sea, where only a few initiatives have been undertaken to reuse parts for the exploitation of new fields. New industrial technology and new environmental policies increase the possibility of developing other ways of decommissioning, with intrinsic social and environmental benefits. An industrial reuse of offshore equipment could involve the injection and storage of CO2, one of the main greenhouse gases, as a tool in negotiating the future trading in greenhouse gas credits. An important role in reuse could be furthered by Gas To Liquids (GTL) technology, which allows the extraction of marginal gas reserves. The continuous technological developments and improved equipment have led to ever smaller plants, which can therefore be mounted on offshore platforms. Based on this premise we have analysed two case studies, brought together in conclusion which could further future research for these kind of reuse. Last, but not least, the possibility of mounting GPS stations will be discussed, potentially on monotubular platforms, without neglecting the need for maintenance, which in this case is relevant.
