G.M. McAllister / Ijssel Confidence, Chesapeake, VA, USA (NTSB DCA19FM053)Report published Nov 16, 2020
The probable cause of the contact of the G.M McAllister with the NGL Energy Partners berth was the docking pilot backing down the river toward the turning basin at a speed at which the assist tugboats could not be effectively used. Contributing to the accident was insufficient communication, before and during the maneuver, between the docking pilot and the G.M. McAllister captain.
