- The tubes in the middle of the S.A.M. appear to be the accumulators no? - The accumulator is designed to provide high pressure hydraulic fluid / gas (nitrogen) to prevent blowouts? - The ability to position the S.A.M. so closely to the system ensures a faster response to the blowout as opposed to longer umbilicals connected to larger accumulators? - Easy retrieval (topshore) for maintenance and convenient positioning enabling more wellheads to operate and therefore reduce costs? - The added benefit of the attached anodes prevents corrosion of electrical equipment?
Great read for those who are more concerned with the technical specs of what Deep Down appears to understand beforehand:
