Hardest part of getting on board of a ship is climbing up on a maximum height of pilot ladder as 9m. Vessel on that video is a 27kdwt bulk carrier in ballast condition bound for İstanbul strait northbound passage.
This video has already been published for the first time in 2020. Please also note the second, more recent video in the appendix. This physical ladder simulator was designed for crew training in the ladder arrangement and for all the users especially for pilots.
The US Coast Guard "Safety Alert 04-22" has been released. The alert addresses the importance of verifying the correct arrangement of handholds in embarkation gate arrangements aboard merchant vessels.
