Initial National Transportation Safety Board report says the SEACOR Power crew hit rough weather shortly before capsizing in the Gulf of Mexico in mid-April.
Salvage crews have pumped more than 20,000 gallons of diesel fuel from the still-submerged lift boat.
Salvage crews are using a special method to remove fuel from the capsized commercial lift boat SEACOR Power.
The process is underway to clear wreckage of the capsized SEACOR Power and minimize environmental impacts.
Eight missing crew members of a Seacor Marine lift boat are presumed dead.
A total of 19 crew members were on board the Seacor Power when it overturned during rough weather 8 miles off of Port Fourchon, Louisiana.
