Overhaul and relocation of FPSO and FSO platforms as an alternative to decommissioning
摘要
Within the best environmental management, reuse precedes recycling, in this sense, the present work seeks to analyze cases of possible overhaul and relocation of FPSO and FSO type platforms belonging to Petróleo Brasileiro S.A.—Petrobras. A field survey was carried out, classifying equipment and systems according to the possibility/need for revamp, retrofit or disposal, as well as compliance with current legislation. The structural integrity of the hull and general support elements was analyzed for the need to replace plates and install reinforcements. The destination fields of the platforms after renovation, with the consequent need for new modules, were determined by the Company. Such information was used as a basis for estimating the cost of the intended reform. These values in terms of ranges were compared with the prices paid for platforms acquired by the Enterprise between 2012 and 2024. Data analysis showed that the business would be advisable because it represents low absolute cost, quick payback and postpones decommissioning costs, although the relative price per unit of weight may eventually be more expensive.
