Edit: Jiangsu Ahn Jin Rubber Co., Ltd.Date: 2018-04-08

U-shaped rubber fenders are one of the important equipments for ship navigation. They can be seen in docks, cargo distribution centers, etc. However, U-shaped rubber fenders are easily damaged during use, causing damage to rubber fenders. What are the reasons?

It is a common phenomenon that U-shaped rubber fenders are damaged during the use of the ship, especially some old rubber fenders, which often crack in the weak parts of the structure. The crack is generally in the length direction of the rubber fender. Type d and U-shaped rubber fenders are more common. The main cause of the cracking of the U-shaped rubber fender is that the kinetic energy of the ship striking the fender is too large to exceed the load that the U-shaped rubber fender can withstand. The reason for the excessive kinetic energy of the ship is that the speed of the ship and the angle of the ship are too large. In particular, when the angle of the ship is large, the ship contacts the pier and the U-shaped rubber fender before the middle of the hull, causing strong impact kinetic energy to concentrate on one or several fenders, causing damage to the rubber fender. The ship's impact function is too large. In addition to the above reasons, there are also ships with docks that are larger than the designed ship type and tonnage, and the impact of wind and waves on the ship.
