Nautical Term: Added weight method
Definition of Added weight method
The Added Weight Method is a calculation technique used in assessing a ship’s stability when it is partially flooded. In this method, the water that has entered the ship is considered an added weight. The hull envelope, which represents the basic structure of the ship, remains unchanged. An alternate approach to this method is through the concept of lost buoyancy.
For instance, suppose a ship is partially flooded, and the added weight of the water is calculated to be 1000 tons. In this case, the stability of the ship would be assessed using the added weight method, with the hull envelope of the ship remaining unchanged while the added weight of the water is taken into account.
