"ONE - MSQ Accident News No. 31": ONE operated 13,900 TEU vessel “M/V Milano Bridge” has collided with gantry cranes and another vessel while approaching berth at PNC #8. This was the first berthing for phasing-in after Dry Dock.

The NTSB determined that the probable cause of the contact of the Miss Mollye D tow with the Route 182 bridge was a loss of control of the tow by the pilot at the helm of the towing vessel, likely due to impairment by factors such as fatigue or drug use.

Manoeuvring large ships at close quarters and on shallow water is one of the most difficult aspects of shiphandling because of the complex hydraulic interactions depending on the ships' speeds, on the water depth and on lateral restrictions like in canals. Training is conducted both on meeting and on overtaking ships in shallow waters. This video shows how overtaking in a canal can easily fail.
