One of these conditions is that the vessel must have a forecastle of at least 0.07 the length of the vessel and of not less than standard height, which is 1.8 m (5 ft 11 in) for a vessel 75 m (246 ft) or less in length and 2.3 m (7 ft 7 in) for a vessel 125 m (410 ft) or more in length with intermediate heights for intermediate lengths. A poop ...
The vessel consists of two major moving parts (port and starboard halves), both are mostly symmetrical in design. Both parts of the vessel are hinged at the deck and operated by hydraulic cylinders. When the vessel splits the load is dumped rapidly, which means the barge has to be very stable in order not to capsize or otherwise get damaged.
Container size – A 20 feet container can not be loaded up on a 40 feet container, but the reverse is possible if the vessel structure allows it. Planners can also load a 40 feet container on top of two units of 20 feet container, this known as a "Russian stowage" or "mixed stowage".
Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessels displacement (obtained from ships 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 loaded ...
On a square rigged vessel, a topsail is a typically trapezoidal shaped sail rigged above the course sail and below the topgallant sail where carried, on any mast (i.e., a fully rigged ship would have a foremast topsail, a mainmast topsail, and a mizzen topsail). A full rigged ship will have either single or double (i.e., "split" upper and lower ...
Waterline of a ship. The mark above the waterline indicates the Plimsoll line. The waterline is the line where the hull of a ship meets the surface of the water.. A waterline can also refer to any line on a ship's hull that is parallel to the water's surface when the ship is afloat in a level trimmed position.
[10] [11] [12] In cold regions, gouging ice features are a threat to subsea installations, such as pipelines. [13] [14] [5] The risks associated with a particular type of geohazard is a function of how exposed the structure is to the event, how severe this event is and how often it occurs (for episodic events). Any threat has to be monitored ...
