Classification society IRClass has recently completed the survey and certification of 'Greatship Ramya' during its conversion from an offshore supply vessel to a well stimulation vessel for Schlumberger under its single class.
Well stimulation vessels are one of the most critical ship types in the offshore segment as they handle hazardous chemicals under very high pressures (close to 20,000psi) and supply and receive these fluids to and from offshore oil wells. Therefore, the classification for such vessels requires stringent norms and compliance with multiple codes like IBC code, IGC Code, IMDG code, and Offshore Standards in addition to the SOLAS and MARPOL conventions.
Due to the tight delivery timelines, Schlumberger chose to get the conversion done under the single class of IRClass. The classification process involved plan approval and surveys during manufacturing, installation on board the vessel, test and trial of acid and various types of process tanks, pressure vessels, high pressure piping systems, engines, generators, electrical installations, safety systems, process handling equipment including the handling of return fluid from the well, their separation, processing and burning through a specially constructed burner boom at the forward end of the vessel.
IRClass worked in close coordination with various parties to accomplish plan approval of 270 drawings and physical surveys of all the equipment, installations and systems within a span of around seven months.
