Nettonuottoluku

Nettonuottoluku, also known as the net tonnage or net register tonnage, is a measure used to indicate the volume of a ship's cargo space. It is calculated by subtracting the volume of the ship's hull, machinery, and other fixed equipment from the total volume of the ship. The net tonnage is expressed in gross register tons (GRT) or net register tons (NRT), depending on the country's maritime regulations.

The net tonnage is an important factor in determining a ship's cargo capacity and is used in various maritime calculations, such as determining the ship's carrying capacity, insurance premiums, and port dues. It is also used to classify ships into different categories based on their size and cargo capacity.

The net tonnage is calculated using a specific formula that takes into account the ship's dimensions, such as its length, breadth, and depth, as well as the volume of its fixed equipment. The formula may vary depending on the country's maritime regulations, but it generally involves measuring the ship's internal volume and subtracting the volume of its fixed equipment.

In some countries, the net tonnage is used to determine the ship's carrying capacity, which is the maximum amount of cargo that the ship can safely carry. The carrying capacity is calculated by multiplying the net tonnage by a specific factor, which may vary depending on the type of cargo and the ship's design.

In summary, nettonuottoluku is a measure of a ship's cargo space, calculated by subtracting the volume of the ship's fixed equipment from its total volume. It is used in various maritime calculations and is an important factor in determining a ship's cargo capacity and classification.
