ABSTRACT: Natural gas is one of the most important energy resources and the worldwide consumption is rapidly increasing. Recently, its consumption is being accelerated because of a growing environmental concern. To satisfy such a demand for natural gas, several gas fields are under development in hostile conditions such as deep seas and Arctic areas. However, due to the status of current technologies and economic situations, many gas fields in offshore are stranded. Stranded gas reserves are those which cannot be economically transported to the consumer due to the distance from the gas field to market or the extreme water depth for laying pipelines. The estimated stranded gas reserves are above 4,500 TCF in offshore areas. The proven technology options available to the offshore sector for natural gas exploitation and transportation are extremely limited. Currently, the most popular methods of conveying natural gas to market from distant locations are through LNG (Liquefied Natural Gas) and PNG (Pipelined Natural Gas) technologies. However, these technologies require considerable capital expenditure for infrastructure construction and huge proved gas reserves. Therefore, in many situations, they are not available for stranded gas transportation

ABSTRACT: 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.
