Summary
Following surface-casing cementing on a Gulf of Mexico jack-up MODU, the well was shut in with the diverter in test mode. Rising pressure led to gas leakage through flow-line seals. Personnel evacuated, but the control configuration prevented remote diversion. No injuries or environmental impacts were reported.
Classifications: Hydrocarbon release; hydrocarbon leak; oil and gas release.
