Data Collection:
Terminology In most cases, the actual values of the ship are used to calculate the effective berthing energy. Under some cases the actual values are not available, then the attached “Standard Sizes of Vessels” shall be referred to for calculation.
| Terminology | Definition |
|---|---|
| Gross Tonnage (ton) | Total volume of vessel and cargo, it is derived by dividing the total interior capacity of a vessel by 100 cubic feet |
| Net Tonnage (ton) | Total volume of cargo that can be carried by the vessel |
| Displacement Tonnage (ton) | Total weight of the vessel and cargo when the ship is loaded to draft line |
| Dead Weight Tonnage (ton) | Weight of cargo, fuel, passenger, crew and food on the vessel |
| Light Weight (ton) | Weight of ship |
| Ballast weight (ton) | Weight of ship and water added to the hold or ballast compartment of a Bessel to improve its stability after it has discharged its cargo |
| Length of Ship (m) | Length from the top of the bow to the end of stem of a ship |
| Beam of ship (m) | The distance across the parallel section of the sides of a ship |
| Laden Draft (m) | The distance from the water surface to the keel of the ship when the ship is loaded to the freeboard mark |
| Light Draft (m) | The distance from the water surface to the keel of the ship when the ship is at light |
| Depth of Ship (m) | The actual depth of ship |
