As explained, a large number of reports related to the use of pilot ladders which are too long relative to the vessel’s draughts. As a result, the excessively long ladders require shortening up before being deployed for boarding pilots. In these cases, ship crew shortens the pilot ladders, using D-shackles to choke the side ropes at the required height along the ladder’s length. In this method, the D-shackle is first secured to a hard point on the deck, such as a pad eye, and the ladder rope threaded through the shackle. Shortening ladders using the D-shackle method causes the weight of the ladder to be taken up by the D-shackle impacting directly against the mechanical securing clamps (widgets) which secure the ladders treads in place, Tokyo MoU explains.

Article Origins of the IMPA pilot mark

There are many things in both our everyday and professional lives which we take for granted and never question the origins of, an example of this might be the IMPA recommended ‘pilot mark or pilot line’, which is sometimes seen on the side of vessels indicating where a vessels freeboard exceeds 9 metres.
Article Results online survey into the securing methods of pilot ladders
by Herman Broers - published on 5 March 2021
It has been shown that a majority (51%) of pilot ladders is secured by means of D-shackles, when secured at intermediate length. Previous research (Evans, 2020) has proven that this method has only about 50% of the strength of the pilot ladder when secured at full length (“double ended ladder”), or by means of the “endless-sling” method.
Opinion Pilot transfer arrangements - Sharing knowledge matters – but problems go beyond non-compliance to SOLAS itself
by Kevin Vallance deep sea pilot and author - published on 23 September 2020
Like many seafarers I have long been a keen follower of The Nautical Institute’s MARS programme, and along with many other members I listened to the recent webinar on that topic. One theme which was repeated more than once was that it is better to learn from someone else’s misfortune rather than have it happen to you. Having personally been involved in two near misses resulting from unsafe pilot transfer arrangements in a relatively short space of time, I asked how experiences and knowledge specifically about pilot ladder safety could best be promulgated to avoid repeating common accidents or near misses.

by Capt.Alpertunga Anıker - published on 24 November 2022
The Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.
