Winds were reportedly 130-145km/h and seas 2.1-2.7m when the Seacor Power vessel overturned. The US Coast Guard are searching for 12 people missing off the coast of Louisiana on Wednesday (local time) after finding one person dead and pulling six survivors from rough seas when their commercial vessel capsized in hurricane-force winds. Coast Guard Captain Will Watson said winds were 130 to 145 km/h and seas were 2.1 to 2.7 metres when the Seacor Power lift vessel overturned. “That’s challenging under any circumstance,” Watson said. “We don’t know the degree to which that contributed to what happened, but we do know those are challenging conditions to be out in the maritime environment.”
