Abstract
The author describes the outline of the berth at Negishi Refinery, Nippon Petroleum Refining Company.This berth is a pier type and enables two 150, 000-ton-sized tankers to bring alongside at one time.
It was constructed on the basis of following conditions, i.e., arri ng speed: 12.5cm/sec., effective width: 6.6m, bearing capacity: 14 ton load of a car, earth shock: 0.2, wave height: 3.0, distance to the opposite shore: 37km, velocity of the wind: 37.4m/sec., and length of wave: 53.3m.
Furthermore the arriving energy of a ship is absorbed both by bending of steel-pipe stakes and rubber fenders.
