ABSTRACT:
A gangway for transferring personnel between a ship and a fixed structure is formed by first and second mating extensible members which are arranged to form a platform. Springs are mounted inside the platform which permit the first and second members to elongate or shorten about a neutral point in order to accommodate a movement of the ship during heavy seas. Attaching devices are provided in each end of the gangway to secure it to the ship and to the fixed structure, respectively. An elastic tread can be placed on the gangway so that, when the gangway elongates or shortens, personnel walking on the gangway will not be injured or lose footing. A plurality of hoops can be attached along the gangway with elastic material stretched between the hoops and covering same so that, should personnel momentarily lose their footing, they will not be thrown overboard.
