Gangway Ladders or otherwise known as Wharf ladders are made of Aluminium Alloy for Sea water induced corrosion resistance. They are used to access the ship from the Jetty while it is docked alongside. The ship end is kept in place using a gunwale hook at one end of the gangway and other end with rollers is kept on the jetty. The gangway is also used for ship-to-ship and ship-to-platform transfers.
