Hurricane Dennis passed through the area where the platform was located, causing it to partially sink. A seawater valve in a ballast tank had been wrongly installed, resulting in excess water in the tanks. The platform had already been evacuated and there was no leakage of oil, fuel, or other hazardous substances. The loss resulted in the project commencing production three years behind schedule. The company retrieved and rebuilt all the seabed production equipment after a series of tests revealed metallurgical failure in components of the field subsea systems.

[ Property Damage $250 Million. Estimated Current Value $350 Million ]
