ChirpMaritime has just released their annual analysis of maritime reports (2022-2023).

Port operations, whether these are being performed on water or on land, are often not without risk. Pilots boarding a ship while sailing, navigating through narrow passages, collision avoidance with other smaller or larger vessels, discharging and moving cargo on land, walking between container handling equipment and trucks…

​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.

Shortly after 5 a.m. local time the vessel “Else” had a collision in the Kiel-Holtenau lock to the Kiel Canal.
The "Else" subject to pilotage passed the pilot's boarding position without taking a sea pilot on board and collided from the outside into the closed gate of the new north lock. The bow bored into the metal construction and the ship was stuck for about six hours.
