Apr 25, 2019Matthew Pilgrim Senior Consultant Engineer (FM Global). Carl, in general transformer bunding is a good idea, but can be a costly exercise for existing installations. Factors to consider are the cost and lead time of the transformer, its impact on production, whether an oil fire would expose adjacent transformers or buildings and the type of oil used (mineral oil, natural or synthetic esters).Bunding and Spill Management Guidelines5.4.1 Tank storages The designed net capacity of a bunded compound in a tank storage facility should be whichever is the largest of the following At least 110% of the volume of the largest storage vessel; or At least 110% of the combined volume of any inter-connected vessels within that bunded area; or
