An implied condition for the safe carriage of goods at sea is that such cargoes shall be delivered, as far as possible, in as good condition and order as it was when received aboard. One way to achieve safe carriage of goods by sea transport is to protect cargoes from the elements, by loading them…
A ship’s ability to navigate safely through a particular area of water depends on how the ship “sits” in the water, in other words, her underwater profile. Her underwater profile which is dependent on her draught determines how much cargo she can load. The draught of a ship determines her displacement, particularly how much underwater…
Discover the 7 essential hull markings found on every ship. From Plimsoll lines to tug and pilot symbols, loading limits, and class compliance under IMO and SOLAS conventions.
Have you ever wondered what the interior of a commercial ship hull looks like? What might be the different subdivisions, tanks, and so on? The aft peak tank is the last tank which acts as the primary structural support towards the aft of the vessel. It lies towards the aft of the aft peak bulkhead.…
The efficiency of a ship is determined by how well all the ship’s machinery and operating systems are maintained. To ensure such conditions are maintained, SOLAS Chapter-I Regulation-10, stipulates that all active ships in the 100A5 category must undergo a bottom survey twice every 5 years. In addition, merchant vessels older than 15 years must…
Sewage is a very smelly topic if left undiscussed. This article will help you understand how the maritime industry handles human waste aboard the ship without violating or harassing the environment. How does a sewage treatment plant work on ships? The sewage treatment plant on the ship begins by collecting and segregating the wastewater from…
How many tons of water do ships boil off to make enough steam aboard? Where do they get this amount of water and where do they dump all of it? If you are wondering how I suggest you continue reading. What Is A Feed System? The boiler feed water system is an important part of…
The stern can be defined as the aftmost section of a vessel. It is the backmost part of a vessel that serves a lot of functions. The stern is designed not only for the vessel’s aesthetics but plays a major role in functionality also. From the basic function of housing navigation lights to advanced hydrodynamic…
The keel of a boat is an essential part of the structure of a vessel. It keeps the vessel stable and prevents the vessel from being overturned into water. The keel of a vessel is typically found at the bottom of a vessel, mostly a fin-like structure, that rests on the seabed, progressing downwards from…
One aspect of a ship that needs additional consideration during design and construction is the hull. In the development of naval architecture, hull designs have gone from cylindrical wooden shanks to steel columns over time. To provide higher structural strength, engineers have been improving hull designs regularly. A variety of forces are working simultaneously on…
