Fender Design (Berthing Energy) Calculator - www.thenavalarch.com

www.thenavalarch.com launches the Fender Design (Berthing Energy) calculator.

A demo video is below:

This excel sheet calculates the berthing energy which the fenders of a berth need to resist when a vessel is berthing

It calculates both the Normal berthing energy (EN) and the Abnormal berthing energy (EA)

This berthing energy can then be utilised to select fenders for the particular berth


Very useful for selecting fenders for a berth
Calculates the berthing energy for both Side berthing or end berthing
