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.

Video Refusing to board due to a pilot ladder not rigged correctly
published on 20 June 2025
This lady came into port in an excellent day, however when I inspected the pilot ladder prior to board I saw that it was rigged using D-Shackles fastened between the side ropes, transferring all the weight and load of the ladder to the clamps and chokes. Truly an unsuitable method of securing the ladder. Retrieval line was also not above the first spreader
After pulling out the pilot boat, the ship was contacted by VHF and the captain was asked to instruct the crew in the usage of ropes and...
Video How the Sabine Pilots are Redefining Maritime Pilot Transfer with Helicopters
published on 17 February 2026
In one of the busiest and most critical waterways in the United States, timing and safety are everything. Along the Sabine-Neches Waterway in Port Arthur, Texas, the Sabine Pilots are redefining maritime pilot transfer by taking to the air. This video follows the Sabine Pilots and HeliService USA as they use Leonardo AW169 helicopters to move pilots safely and efficiently between ships—reducing risk, improving responsiveness, and keeping America’s energy gateway moving. From offshore hoists...
