A barge proprietor’s lack of inspection and upkeep led to the capsizing and sinking of a crane barge final 12 months within the Gulf of Mexico, the National Transportation Safety Board (NTSB) mentioned.
The crane barge Ambition was being towed when it capsized and sank on June 15, 2022, releasing an estimated 1,980 gallons of oil. No accidents had been reported. The Ambition, owned by Rigid Constructors, and its crane had been a complete loss estimated at $6.3 million.
Due to the peak of the crane, the Ambition was being towed offshore within the Gulf of Mexico to achieve its vacation spot.

At some level, a short lived restore, consisting of metal plates, had been made to the world across the separation to include water ingress. Based on the hull plating separation and wastage on the inside bulkheads, the NTSB decided the poor hull situation was the reason for the preliminary flooding. According to investigators, Rigid Constructors did not conduct everlasting repairs in an space important to hull power, and the separation between the underside plating and the bilge knuckle plating progressed past the momentary restore.
The NTSB decided the possible reason for the capsizing and sinking of the Ambition was the barge proprietor’s lack of hull inspection and upkeep, and never conducting everlasting repairs, which resulted within the failure of the hull and subsequent flooding.
“To protect vessels and the environment, it is good marine practice for vessel owners to conduct regular oversight and maintenance of hulls, including between drydock periods,” the report mentioned. “An effective maintenance and hull inspection program should proactively address potential steel wastage, identify hull and watertight integrity deficiencies, and ensure corrosion issues are repaired in a timely manner by permanent means.”
