Full load displacement and loaded displacement have almost identical definitions. Full load is defined as the displacement of a vessel when floating at its greatest allowable draft as approved by the load line assigning authority which is either the flag state (USCG etc) or a classification society (and designated by its " load line ").

Full load departure or full displacement [ edit ] Along with all the Lightship loads, the vessel has all systems charged meaning that all fresh water, cooling, lubricating, hydraulic and fuel service header tanks, piping and equipment systems are filled with their normal operating fluids.
They then calculate the righting moment at this angle, which is determined using the equation: = Where RM is the righting moment, GZ is the righting arm and Δ is the displacement. Because the vessel displacement is constant, common practice is to simply graph the righting arm vs the angle of heel.
Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage).
Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...
The Paluma-class vessels have a full load displacement of 320 tonnes. [1] They are 36.6 metres (120 ft) long overall and 36 metres (118 ft) long between perpendiculars, have a beam of 13.7 metres (45 ft), and a draught of 1.9 metres (6 ft 3 in). [1]
A second vessel was planned in 1980, but not optioned. Construction of Success was slow and costs increased. [16] The modified Durance-class oiler is 157.2 m (515 ft 9 in) in length, with a beam of 21.2 m (69 ft 7 in), and a draught of 8.6 m (28 ft 3 in), with a full load displacement of 18,221 t (17,933 long tons).

The ship is armed with one 76 mm gun and four 30 mm close-in weapon systems. [6] A Type 071 hull (986) was modified with a laser -based directed energy weapon added to the vessel's forward superstructure in 2024, reflecting the configuration of a similar weapon installed on the San Antonio -class ship USS Portland .
