NTSB report in grounding published

A software flaw combined with the captain’s failure to use back-up controls led to the grounding of the 'Commodore' in New York City ib June 5, 2021, the National Transportation Safety Board said Oct 25, 2022. The vessel was transiting northbound on the East River when it lost primary steering and speed control to both of its port hull water jets and then grounded. One minor injury was reported among the seven crewmembers and 107 passengers on board. The grounding resulted in $2.5 million in damages to the vessel. The ferry, providing commuter service between Manhattan and New Jersey, was operating its second trip of the day to a New York City Ferry Terminal from Sandy Hook, New Jersey. After passing under the Brooklyn Bridge, an alarm alerted indicating a control failure for the port water jets. The captain unsuccessfully attempted to reconnect the port jets several times via the primary control system. The captain first attempted to slow the vessel, then he attempted to go full astern, but only the engines and water jets in the starboard hull responded. This resulted in the ferry turning to starboard and slowing. It crossed to the east side of the river and entered the relatively narrow opening to Bushwick Inlet. Less than two minutes after the alarm, the vessel grounded. The port hull was breached after contact with submerged pilings on the north shoreline of the Bushwick Inlet and seawater quickly entered the port engine room. NTSB investigators found that the captain never tried to engage the back-up control, which could have been used to operate the vessel following the loss of primary control and more effective company training procedures for loss of propulsion or steering control would have included recognizing a control failure and then responding by using the back-up control or other alternatives. Following the grounding, a service engineer determined the primary control system software was generating an unprecedented number of error messages, which caused the SD card for the display screen controlling the port water jets and engines to fail. This failure resulted in the loss of the display monitor and the loss of primary propulsion and steering control for the water jets and main engines in the port hull. A month after the grounding, the manufacturer issued a service letter to its customers mandating a software update that would correct the issue that caused the problem on the Commodore. The NTSB said the probable cause of the grounding was the loss of the primary control system for the catamaran’s port water jets and propulsion engines due to a flaw in the system manufacturer’s software causing a memory card failure. Contributing to the casualty was the company’s lack of clear safety management system procedures for control system failure and ineffective oversight of crew training on loss of propulsion and steering control, resulting in the captain not identifying the nature of the loss of control and either engaging back-up control or using emergency engine shutdowns to stop the vessel.

Ferry grounded in Bushwick Inlet

The US Coast Guard, New York City Fire Department (FDNY), and New York City Police Department (NYPD) crews responded to the grounding of the 'Commodore', which operates between New Jersey and New York City, with 118 passengers and seven crew members aboard in Bushwick Inlet, New York, on June 5, 2021, Watchstanders at Coast Guard Sector New York command center received a report that the ferry had grounded enroute from Highlands, N.J., to the East 35th Street in Manhattan when it began to drift due to a mecanical failure and landed on the shoreand was taking on water in Bushwick Inlet in Brooklyn, New York, at approximately 4:17 p.m. Three boat crews from Coast Guard Station New York were launched and began rescue efforts with FDNY and NYPD crews. NYPD and FDNY safely evacuated all passengers and crew members from the ferry, one of whom was slightly injured, and Coast Guard Station New York members went aboard with FDNY members to conduct dewatering operations. Coast Guard investigators started investigating the cause of the grounding. At approximately 3 a.m., the ferry was refloated and towed back to the dry dock of shipyard. Seastreak worked with its regulatory agency, the USCG, to determine the root cause of the failure.
