How to calculate the strength of Midship Section of a Ship

The mid-ship section of a ship is a defining structural drawing of the vessel. It represents the most critical structural parameter of the vessel – its global strength. To assess how much of the bending moment (hog and sag) the vessel can tolerate, it is important to...

How to use empirical formulas to estimate the resistance of a Ship

How to use empirical formulas to estimate the resistance of a Ship Resistance estimation holds immense importance in the design stage of a vessel. Based on the results of the resistance estimation of a vessel, the selection of the right propulsion system is done....

Designing the berth mooring of your vessel with this simple yet effective method

A vessel at berth experiences much lower forces compared to a vessel in the open sea due to the milder environment, but it still requires a mooring configuration suited to the forces it experiences, and also suitable for the type of berthing configuration adopted. The...

Bulbous Bows – History and Design

by Bijit Sarkar, Naval Architect Introduction The eternal search of a naval architect – a perfect bow. Sadly, it never exists. Different bow forms are good for different types, sizes of vessels and seaways. What does a naval architect want out of the bow he designs?...
