Whether you are preparing for your marine certifications, or simply interested to learn more about how boats are designed and built, find a source that meets your needs. Explore topics of ship building and design, including how oil tankers float, what types of rudders are used on various ships, how a submarine works and much more.
As a Mariner everybody should know the importance of the bridge, installed equipment, and different operations performed inside it essential for safe navigation. Let’s take a tour inside the bridge- the commanding station of the ship.
A ship, as seen in a port, is not calm when it heads out to sea. It experiences huge waves and obeys the degrees of freedom- rolling, pitching, yawing, swaying, heaving, and surging. Even after experiencing such tremendous forces, it does not capsize. Read here to learn more about ship stability.
This article will give you a clear picture on a survey of current sailboats, along with the various stresses acting on the hull of the sailboat and the various hull designs now in use.
New hull designs that minimize wake creation. These boats are fuel efficient and fast, while increasing safety due to their low wake height.
Marine toilets are known as the head, this being the name given to them on the old wooden sailing ships, as they were located in the ships head right at the bow. They were placed each side of the bowsprit and used by the officers and crew, with only the captain having his own toilet.
Various desalination technologies are being adopted in the modern world. Of these, one of the new technologies, which I had a working experience with in converting an oil tanker to a desalination vessel in dry dock, is described in this article.
This article explains the importance and use of Castigligiano’s theorems in relation to ship design for forces in an elastic structure and displacements in a linearly elastic structure
A naval architect has an important role in the design and manufacturing of marine vessels. They are responsible for much more than the initial design.
In basic ship designing, Euler’s equation of motion plays a vital role in finding the behavior of the ship in fluid dynamics. It is mainly use in propeller design and relating the concepts of vortex.
There are many advanced commercial CAD boat design applications available. However, this article will discuss the use of one freely available, but sufficiently powerful, CAD boat design program.
The Vikings sailed to many parts of Europe in their long ships, initially powered by numerous rowers and augmented later with a single square sail. Their ships were invariably clinker built, being conceived and designed in the shipwrights mind with little detail being committed to paper in drawings.
In this article we discuss the pirate ship designs of the 1700s and 1800s that were contributory to the golden age of piracy. The pirates had no opportunity to design ships and they were all captured. These ships were soon modified for speed, firing power, and hull was reinforced in critical places.
Cruise ships have special boat building methods to ensure the comfort and the safety of passengers. As humans are the most precious cargoes that can be carried on board the ship, designers and the ship owners are very careful for the safety and wellbeing of the passengers.
A nuclear submarine is considered one of the most technologically advanced defense systems that a country can have. Using a nuclear reactor produces a huge amount of energy that can last for several months together. Learn about this type of submarine design and its workings inside this article.
An Autonomous Underwater Vehicle or AUV is a deep sea vehicle which operates without any kind of external interference. Technically a robot, a AUV performs all deep sea functions automatically.
A bathyscaphe is a type of submersible vessel used for exploring the depths of the sea. Known as the only manned vessel to reach great depths, bathyscaphes, unlike a conventional submarine, has a unique ascending and descending system. Learn more about bathyscaphes in this article.
Offshore structures such as oil and gas platforms require protection from corrosion in the marine environment. These huge installations are constructed from carbon steel plates and rolled sections. This renders them particularly susceptible to corrosion in the hostile conditions they operate under.
Corrosion protection of our ships in the marine environment has challenged us for years in the areas of their hulls and internal tanks, the use of coaltars being prevalent. Nowadays however there are many innovative types of epoxy coatings and specialized paints available to combat corrosion attack
Naval architects designing ships like to allot maximum space for cargo carriage and minimal space for the engine room. For several reasons, the layout of the engine room should be such so that the maintenance and the cleanliness of the engine room should not suffer because of poor design.
Ships when at sea require stability to sail safely. For this reason sea water is taken into the bottom of the ship in specially made compartments. This water used for ship’s stability is known as ballast water. Find out more about ballast water and ballast water tanks in the article inside.
