Low Pressure Weather Systems News

The NTSB recently investigated an accident that required the crew to abandon a weather-damaged liftboat in near-hurricane-force conditions. The company hurricane plan did not account for rapidly and locally developing low pressure weather systems. This reduced the crewmembers’ ability to properly plan for the developing storm and to make an early decision to leave the vessel through routine means before the onset of the storm. The vessel had recently been equipped with two new inflatable throw-over-type liferafts. However, the liferafts were inflated on deck instead of in the water when the crew prepared to abandon the vessel. This led to the liferafts blowing away from the vessel and vanishing in the high winds and seas.
