Let’s take a look at intact stability criteria and inclining experiment, the two stages of ship design and construction where evaluation of GM is an absolute necessity and plays a major role in ensuring that the ship is stable.
Learn about some major cases of instability in ships and different measures that should be taken in design and operational stages to prevent the same. Read more inside the article.
The easiest and handiest tool for analysing a surface ship’s stability, is by graphs or curves. A ship designer or an officer on-board should be able to know the stability characteristics of a ship just by looking at the curves. Let’s understand curves of static stability of a vessel.
The fundamental concept behind the understanding of intact stability of a floating body is that of Equilibrium. Let’s take a look at different types of factors responsible for intact and damaged stability of a ship.
Manoeuvrability is defined as the inherent ability of a vessel to change its course/path. Understanding the factor of manoeuvrability of a vessel is extremely important to both ship designer or seafarer. Read more about different types Of manoeuvres of a vessel inside the article.
The concept of hydrostatics and stability can be deemed as one of the most important areas of focus in ship design and operation, not only to ensure the safety of the ship, cargo, crew and passengers, but also to enable proper conditions for completion of all the processes on a ship.
Though a typical diesel electric submarine would have more than 150 systems in all, lets take a look on the primary systems used on-board a naval submarine.
Approximately 40% of the focus and priority in the entire submarine design process is given to its structural design. The full process takes up majority of the time, as it is not only related to strength factors of submarine, but also to a nexus of functional aspects that are interrelated to it.
Though some of the tanks used in a submarine are similar to that used on surface ships, most of them are different and unique to the nature of operation of a submarine, which makes it an important aspect to be studied in detail.
Learn about the important aspects of submarine stability and the principles necessary to understand how a submarine works in the article inside.
In this first part of the submarine design series, we will learn about the design of naval submarines, familiarising ourselves with the design and functionalities of a submarine, its parts, general arrangement, structural design and arrangement, stability of a submarine, the systems used in a submarine, etc.

Want to know how the design of different types of gas carriers vary depending on the type of the cargo and membrane tanks? Read more about construction of gas ships inside the article.
Want to know how the design of different oil tankers vary depending on the type of the cargo they carry? Read more about it inside the article.
We are familiar with the form of ship propeller, but have we ever contemplated upon their shape, appearance and typical geometry? Let’s find out inside the article.
Design of container ships depends on type of cargo, the ports on route, the functionality of the ship, and also the economic trends in the market. Lets take a look at the important aspects considered for container ship design.
Let’s take a look at the final processes of the shipbuilding process followed by launching, outfitting and sea trials.
It is worthwhile to mention that in most of the places describing the preliminary design of ship’s hull structures, utmost priority is given to the midship section, thanks to the global stresses such as maximum hull girder bending and buckling loads taken into account. However, the fore and aft parts of the ship are not to […]
