Gas-Ares

A pilot’s order to reduce the speed of the 'Gas Ares' during strong crosswinds led to a collision with a moored tug near Port Neches, Texas, the National Transportation Safety Board (NTSB) said on Nov 10, 2022. The vessel was transiting upbound on the Neches River on Nov. 25, 2021, when it collided with a harbour tug, which was moored alongside another tug at a loading dock at the Motiva Port Neches Terminal. None of the eight people on board the moored tugs or the 24 people on board the Gas Ares were injured. The contact resulted in $1.1 million in damages to the tugs and dock. A state licensed pilot from the Sabine Pilots took navigational control of the 'Gas Ares' as it was heading to a loading dock on the Neches River. Due to wind conditions, he planned to have an escort tug for the transit through the Sabine Neches Canal and Neches River. After the pilot arranged a passing with a tow,he ordered the 'Gas Ares' to dead slow ahead to avoid making a wake as the carrier passed a pipeline removal project to starboard near the shoreline outside of the navigation channel. Winds were strong on the tanker’s starboard side, slowly setting the vessel, which was already on the left side of the 400-foot-wide channel, for the passing arrangement with the tow—further toward the left side of the channel toward vessels moored at docks on that side of the channel. With the reduction of the ship’s speed, the rudder became less effective, and was not able to move the vessel to starboard and away from the moored vessels on the left side of the channel by rudder and engine alone or by using the escort tug to pull on the vessel’s starboard quarter. Without enough headway, the pilot was unable to steer the vessel back to the center of the channel and avoid striking the outboard moored tug. The NTSB determined the probable cause of the collision was the pilot’s decision to reduce the vessel’s speed in order to create less wake when passing a pipeline removal project, causing a loss of rudder effectiveness in strong crosswinds that set the carrier toward moored vessels.
