Play video to 24:00 minutes past the hour. Ship has barely entered frame, external lights on, no visible exhaust, however has already started turning according to track at 24:54.
External lights off (not all lights off though) at video 24:33 past the hour. On the track at 25:27, ship continues to noticeably turn. Does not seem to slow down, does not seem to strafe.
Lights back on at video 25:31, 10 seconds after lights come back on there is now visible exhaust, this exhaust will remain. Lights off again at video 26:37. Following track 26:25 to 27:31, the ship does not slow down, and does not begin to strafe, but seems to continue turning, in the video and the track.
Lights go back off at video 26:37 and back on at video 27:10. During this time track 27:31 to 28:04 continues to show no noticeable decrease in speed, and seems to barely turn at all.
At approximately track 28:50 ship appears to begin to slow down. That would be video 27:56. Despite the decrease in speed from video 27:56, ship does not appear to actually begin turning away until approximately video 28:35.
Is there any way an engine on one side goes out and engines on the other side makes it turn. I'm having a discussion with my cousin and he's thinking this could happen like outboard motors which i disagree with.
Yes. Big ships have multiple propellers. Steering is commonly done be reversing the thrust direction some of the propellers on one side of the ship, while the other propellers thrust in the opposite direction. Losing power to half of the props could likely turn the ship.
edit: It seems pretty clear that a manual override should have been able to stop that ship from turning into the column. Really interesting videos. Thank you again.
Fine I will be that guy.

According to https://tidesandcurrents.noaa.gov/stationhome.html?id=8574680 at approximately 01:24 local, tide was lowest at 1.79ft. Wind was 0.19kn gusting to 0.78kn from NW.

According to https://www.shipspotting.com/photos/2909694 the DALI has a DWT of approximately 116,000 tons. According to http://1worldenergy.com/ship-sizes-speeds-voyage-times-maritime-regulations/ that would make it most likely a panamax, reinforced by recent port call according to https://www.vesselfinder.com/vessels/details/9697428

I pictured you watching this on a different screen and typing out what you were seeing.
Accurate.

I’m pretty sure this is a single engine and propeller ship, maybe someone can clarify

Thank you for this data! This guy is not the guy we deserve, but the guy we need.
