UKC = Charted Depth − Draft-/+ Height of Tide. Ship masters and deck officers can obtain the depth of water from Electronic navigational charts. [5] More dynamic or advanced calculations include safety margins for manoeuvring effects and squat. [7] Computer systems and software can be used to manage and calculate UKC for ships and ports.
A deep-penetrating anchor (DPA) is conceptually similar to a torpedo anchor: it features a dart-shaped, thick-walled, steel cylinder with flukes attached to the upper section of the anchor. A full-scale DPA is approximately 15 metres (49 ft) in length, 1.2 metres (4 ft) in diameter, and weighs on the order of 50–100 tonnes (49–98 long tons ...
Oil and gas recovery at great depth could have been a very difficult task without the suction anchor technology, which was developed and used for the first time in the North Sea 30 years ago. [1] The use of suction caissons/anchors has now become common practice worldwide. Statistics from 2002 revealed that 485 suction caissons had been ...
Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessel's displacement (obtained from ship's stability tables) so as to determine the mass of cargo on board. Draft, Air – Air Draft/Draught is the distance from the water line to the highest point on a ship (including antennas) while it is ...
A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". [1] That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed.
Single anchor leg mooring (SALM), which can be used in both shallow and deep water. [1] see Thistle SALM as an example. Vertical anchor leg mooring, which is seldom used. [1] Two types of single point mooring tower: Jacket type, which has a jacket piled to the seabed with a turntable on top which carries the mooring gear and pipework [1]
Ship stability, as it pertains to naval architecture, has been taken into account for hundreds of years. Historically, ship stability calculations relied on rule of thumb calculations, often tied to a specific system of measurement. Some of these very old equations continue to be used in naval architecture books today.
Keel depth (sometimes given as Depth to keel) is the depth (or draft) of water from the water surface to the keel of a vessel, the deepest part. The keel establishes a commonly defined reference point to measure to. Keel depth is useful for determining safe operating depth in shallow water.
