MUMBAI, India – IRClass has completed the survey and certification of Greatship Ramya during its conversion from an offshore supply to a well stimulation vessel for Schlumberger.
The ship is currently working for an Indian oil company in the offshore sector.
Well stimulation vessels handle hazardous chemicals under very high pressures (close to 20,000 psi/1,379 bar) and supply/receive these fluids to and from offshore wells.
Classification requirements include compliance with IBC, IGC, and IMDG codes and various offshore standards, in addition to the SOLAS and MARPOL conventions.
Due to the tight delivery timeline, Schlumberger opted to have conversion performed under single class status using 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, fluids separation, processing and burning through a specially constructed burner boom at the forward end of the vessel.
IRClass worked with various parties to accomplish plan approval with 270 drawings and physical surveys of all the equipment, installations and systems, the process took around seven months.
