This class notation is related to the ballast water management on board the ship.
This class notation denotes that the ship is allowed for the in water survey of the hull and does not need to be dry docked every 2.5 years. This means that the ship is designed and constructed as per point 5 and chapter 5 & 6 of the class rules of this classification society. As per this class notation, the ship is built for carrying the oil and chemical cargoes in bulk. The whole idea of this notation is to show that ship complies with the construction rules of a classification society.
If the vessel is changing the classification society, the main class notation will also be given if it complied with the rules of the previous classification society. If a vessel is given the main class notation, it means that the ship’s hull, machinery, and equipment complies with the rules of that classification society. Let us see a class notation of a real ship. Here are the rules regarding class notation from few of the classification societies But if there is no UMS notation in the “certificate of class”, it would be a crime to leave the engine room unmanned.ĭifferent classification societies can have their own ways of denoting the class notations. At least the master and chief engineer must be aware of that.įor example, a ship may have all the elements required for operating the engines on UMS mode. It is so important that ship’s officers understand the construction capabilities (and limitations) of their ship. Where can we look?ĭid you get that right? Class notations !!! We want to know if the ship is built for the UMS operation. Where can we find this information? We can look at the class notations in the certificate of class. These notations are the symbols that signify the standards to which the ship is built.įor example, we want to know if the ship is constructed and strengthened to navigate ice areas. Where can we find the class notations and what are these for?Ĭlass notations are mentioned in the “ certificate of class” of the vessel. When a master or chief engineer joins the vessel, this is one of the first things that they must look at. In this post, we will discuss 5 terms related to the classification society of the ship. If the classification society is so much connected with the ship, doesn’t it make necessary for us to know everything about how it works? You will deal with Classification Society of the ship during all these and more. It is something that no ship can sail without.ĭrydocks surveys, statutory surveys, ship building, ship repairs, ISM, ISPS surveys.
