WASHINGTON (Aug. 28, 2025) – A steering control system component failure on a multi-purpose carrier caused a collision with a bulk carrier in the Houston Ship Channel, according to a report released Thursday by the National Transportation Safety Board (NTSB).
The incident occurred on Aug. 25, 2023, when the multi-purpose carrier BBC Africa lost steering as it was departing the channel and struck the moored bulk carrier Common Faith. No injuries or pollution were reported, but vessel damages were estimated at $1.1 million.
Investigators found that the BBC Africa’s steering was operating properly during pre-departure tests and while under port bridge wing control. Problems occurred when control was transferred to the bridge’s center helm, causing the rudder to swing hard to port against orders. The crew attempted multiple times to regain control before the master used the emergency override function, but the maneuver came too late to prevent the collision.
The NTSB determined that the collision was caused by a failed micro switch in the bridge wing tiller, compounded by a delayed emergency steering response from the crew. Following the incident, the operator replaced several steering system components, and the steering gear manufacturer issued a safety bulletin warning of micro switch failures that could lead to unintended rudder movements.
Marine Investigation Report 25-33 is available on the NTSB website.
