The vid shows the stern swinging around to the left and pointing the bow directly pointing at the stanchion it hit. Why did the pilot go to hard right rudder and appears to aim the bow for collision?
I give up, why?
To my embarrassment and astonishment, I learned that the Dali, built by Hyundai Heavy Industries in South Korea, meeting the designs of the owner Oceanbulk Maritime SA and ocean transport service Maersk:
https://en.m.wikipedia.org/wiki/MV_Dali
was “a single screw.” I incorrectly assumed at least “twin screws” - 1 port side plus 1 starboard side.
A single screw boat / ship / vessel is prone to the propellor “walking” (known as paddlewheel effect or asymmetric blade thrust) - partcularly when the vessel is set to run in Reverse motion.
From the rear view: A right hand prop rotates clockwise when the vessel is set to run in Forward motion . . . and counter-clockwise when the vessel is set to run in Reverse motion.
In Reverse, the stern of the vessel “walks” to port - to the left.
(In my previous considerations (twin screws), I imagined that, in Reverse, only the starboard prop was functioning during the emergency reverse. And thus, ONLY the right rear of the ship was pulling toward the rear.)
So, in the crosswind of 8 knots from the east “working” on the very high and large “sail” of the vessel+containers ship heading southeast, and now including the prop “walking” the stern to port . . . the FSK Bridge support was in the way.
The ship has 1 stern rudder, plus 1 bow thruster.
When in forward motion (”under way”) and very heavy, but single screw in reverse, the rudder is initially not a significant contributor. The bow thruster also not much help - if it was working.
