Learn Standard Terms of Ship Stability

   This short educational video was produced with the intention to get the students familiarized with the most important terminology used to describe the hull of a ship. The first four terms are fairly basic. "Depth" is the height of a hull from the highest point of its main deck to its lowest point. In the other direction, the ships "Beam", or "Breadth", is the width at the widest point. The "Centerline" is the vertical plane that runs the length of the ship at the midpoint of the beam, and the "Baseline" is the horizontal plane perpendicular to the centerline located at the lowest point of the hull...

Fresh Water Allowance

   In this video I am going to discuss about the Fresh Water Allowance, FWA. Well, to understand Fresh Water Allowance, let us first understand the purpose of Load Line. Vessel is loaded up to the required permissible load line to avoid overloading. There are various states of load line which I am going to discuss later on. So, the vessel is having the supposed required permissible load line and is floating in fresh water. Howehev, let us ship this water into the salt water. Now, let us discuss about density, also. The relative density of the fresh water is 1, which simply means that density of it is 1 t/cub.m. Similarly, the relative density of the salt water is 1.025 which means that the salt waters density is 1.025 t/cub.m...

Dock Water Allowance

   A very short lecture giving the basic understanding of of the DWA. First, let me define what is the deck water. We know that the fresh water density is 1.000 t/cub.m., or it means that the relative density is 1. The sea water is having the density of 1.025 t/cub.m., and the relative density of the salt water is 1.25. Any water which lies between these two limits, is called Dock Water. Now, let us understand this concept...

Buoyancy and Metacentric Height

   Video training file prepared by Rajiv Gandhi University of Knowledge Technologies, Department of Mechanical Engineering. The lecturer will explain the basics of the Buoyance and Metacentric Height - what they are, how they can be determined and evaluated etc. It will be very useful for students or any persons studying the naval architecture and ship stability as the knowledge of these fundamental issues is of the utmost importance. The conditions of stability have also been addressed in this video lecture.

How Maritime Law is Controlled by Organizations, Flag States and Port States

   This video contains the overview of the complete lecture about the correlation between the different kind of inspectors and different organizations. Both have an influence on the safety of the ships, their personnel and environment. My name is Gilles van der Meij, I worked twenty years at sea and six years as a classification society surveyor.

Stability of Fishing Vessels
   I learned how to fish from my father who learned it from my grandfather. I have been fishing for thirty years and have experience of worst conditions at sea... Fishing is one of the most dangerous occupations in the world with more than 25000 fatalities every year. It is estimated that in some countries the capsizing of fishing vessels accounts for more than 50% of fatalities. This situation, however, can be remedied. The skipper, and his crew, and fishing vessel owners with the assistance of experts, such as the naval architect and boat builder, can act to ensure the safety of their fishing vessel. At the heart of fishing vessel's safety is the concept of fishing vessel's stability.

plimsoll line
   As we know from the course of the Naval Architecture, the Plimsoll line is a mark on a side shell of a ship indicating to what level the ship can legally be loaded to ensure safe sailing. It is clear that different ships have different levels at which they float, therefore the Plimsoll line will be different and depend on the type of ship or boat. The level the line is at will also change depending on the season as well as the type of water the vessel is sailing in.
