Analysis

The plt had landed on the offshore heliport in the gulf of Mexico. The S76 helicopter rolled backward on the platform with the helicopter tilting to its right. The coplt exited the acft and found the right main gear wheel off the platform and into the deck safety net. The plt attempted to lift up off the platform but the acft went off the platform and fell inverted in the water about 100 feet below. The coplt had exited the acft (prior to the accident) after initial touchdown. The helicopter was intentionally landed on the FAR right (east) side of the platform because of a bell 206 which was parked on the left (west) side of the platform.
