Offshore structure, fender device for offshore structure, and method for moving toward structural body constituting offshore structure

A fender device for an offshore structure, comprising:

• fender portions vertically extending and arranged side by side at a predetermined interval;
• and
• rung portions for a person to move up and down the rung portions while placing his/her hands and feet thereon,
• wherein the rung portions horizontally extend from the fender portions toward a base of the offshore structure, which is a target on which the fender device is installed, and are installed at predetermined intervals in the vertical direction of the fender portions,
• wherein the fender portions are constructed to allow part of a ship's hull to make contact with them.

A method for moving toward a structural body of an offshore structure, comprising the steps of:

• part of a ship's hull making contact with fender portions that vertically extend at positions spaced apart from a base of the offshore structure by predetermined distances;
• a worker on board the ship transferring to rung portions located closer to a sea water level among rung portions that extend horizontally from the fender portions toward the base and are installed at predetermined intervals in the vertical direction of the fender portions to allow the worker to move up and down the rung portions;
• and
• the worker moving vertically upward toward an upper surface of the base while placing his/her hands and feet on the rung portions.
