Foam Filled Fenders have most advantages of heavy duty and free maintenance. It is advanced for the “soft bounce” and becoming the best choice as bumpers for platform and docks. They can also be equipped for salvage tugs and oil platforms especially in heavy and fierce environments.   The closed cell aspect of the energy absorbing.. read more →

Calculating Berthing Energy 2.c)

0 Comment

Calculating Berthing Energy 2.c) C) Eccentricity- Ce Usually the ship is not parallel to the pier face during berthing. As a result, not all of the Kinetic Energy will be transmitted to the fenders. At impact, the ship will start to rotate around the contact point thus dissipating part of its energy. The following graph.. read more →

Calculating Hull Pressure

0 Comment

Calculating Hull Pressure The most commonly accepted practice for calculating hull pressure is to calculate the average hull pressure by dividing the reaction of the marine fender over the entire frontal flat area of the marine fender panel. While this calculation normally serves as a good parameter for sizing fender panels often times it does.. read more →

Compressive and Shear Analysis of Rubber Block The circular shaped blocks uniformly bulges outward for the applied normal force and the shape change also progressively increased on increasing the magnitude of compressive force. Under the shear force of same magnitude the block shear out from inward to outward direction for the applied force creating an.. read more →

The Design Process of Fendering Systems Many factors contribute to the design of a fendering system: Ships Ship design evolves constantly – shapes change and many vessel types are getting larger. Fender systems must suit current ships and those expected to arrive in the foreseeable future. Structures Fenders impose loads on the berthing structure. Many.. read more →
