Abstract: At 12:30 p.m. on April 29, 2022, an employee and a coworker were working at a construction site located beneath a pier conducting piling repair work. Part of the work included installing piling jackets equipped with sacrificial anodes. The employee and coworker were free diving in an attempt to recover a fallen piling jacket. The jacket had fallen off the structure and sunk to the bottom of the ocean beneath the pier. On a third attempt to recover the jacket, the coworker surfaced but the employee did not. The employee had drowned and his body was recovered by the coworker. Emergency response efforts were made by coworkers and emergency medical staff, but the employee was pronounced dead after arriving at the hospital.
