The Mumbai High North oil platform fire was caused when a support vessel collided with the platform during a medical evacuation, severing a gas riser and causing an explosion and fire. 22 people died and the platform was destroyed. Key issues identified were deficiencies in risk assessment processes, poor safety culture, vulnerabilities of the risers and vessel, and inadequate rescue efforts. The incident highlighted the need for thorough risk assessment and management of riser damage risks as well as adoption of good collision avoidance practices.

13. IntroductionMUMBAI HIGH North Discovered in 1974

14. 160km west of the Mumbai coast.MHW is a relatively recent additional process platform. MHN is a processing platform (1981)MHF is residential (1978)NA is a small wellhead platform, circa 1976 (first offshore well in India).

15. IntroductionThe complex imported fluids from 11 other satellite wellhead platforms and exported oil to shore via undersea pipelines, as well as processing gas for gas lift operations. The seven-storey high Mumbai High North (MHN) platform had five gas export risers and ten fluid import risers situated outside the platform jacket. In July 2005, a multi-purpose support vessel (MSV) collided with the MHN platform, severing at least one gas riser and causing a massive fire which destroyed the MHN platform within two hours.Weather=Monsoon

17. Mumbai High North Platform Fire, IndiaOverview

18. The AccidentThe fire occurred on 27 July 2005 - a multi- purpose support vessel (MSV), Samundra Suraksha,100m long, hit one of the MHN platform risers.Vessel owned by ONGC but operated and maintained by another nationalised company, the Shipping Company of India (SCI).Vessel working elsewhere in the field, supporting saturation diving operations. Cook cut off the tips of two fingers, and transfer sought to MHN complex for medical treatment.Monsoon meant that no helicopters were available, so the vessel came alongside MHN to affect a man-riding basket transfer. MSV: SamundraSuraksha

19. The AccidentLeeward crane on MHN was not working, so vessel came onto the windward side (wind 35 knots, swell 5 metres, sea current 3 knots). Problems with azimuth thrusters – came alongside under manual (joy stick) control in emergency mode, stern first. The casualty was transferred off the deck by craneThe vessel experienced a strong heave, and the helideck struck the risers (export gas lift).The resulting leak ignited very quickly afterwards. The resulting fire engulfed virtually all of MHN and MHF, with NA and the Noble rig severely affected by heat radiation.
