Bay – a space on the ship that can hold containers, container ships have several bays, these bays are divided into two parts: on-deck and under-deck (hold). If the bay number is odd it is suitable for 20 feet containers, if the bay number is even it is suitable for 40 feet containers. [3] [12]
The beam of a ship is its width at its widest point. The maximum beam (B MAX ) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H ) only includes permanently fixed parts of the hull , and beam at waterline (B WL ) is the maximum width where the hull intersects the surface of the water.
Grain Cube (or Grain Capacity) – The maximum space available for cargo measured in cubic metres or feet, the measurement being taken to the inside of the shell plating of the ship or to the outside of the frames and to the top of the beam or underside of the deck plating. It is a measurement of capacity for cargoes such as grain, where the ...
The vessel's clearance is the distance in excess of the air draft which allows a vessel to pass safely under a bridge or obstacle such as power lines, etc.A bridge's "clearance below" is most often noted on charts as measured from the surface of the water to the underside of the bridge at the chart datum Mean High Water (MHW), [3] [4] a less restrictive clearance than Mean Higher High Water ...
Boat deck: Especially on ships with sponsons, the deck area where lifeboats or the ship's gig are stored. Boiler deck: (river steamers) The passenger deck above the vessel's boilers. Bridge deck: (a) The deck area including the helm and navigation station, and where the Officer of the Deck/Watch will be found, also known as the conn.
The orthotropic deck may be integral with or supported on a grid of deck framing members, such as transverse floor beams and longitudinal girders. All these various choices for the stiffening elements, e.g., ribs, floor beams and main girders, can be interchanged, resulting in a great variety of orthotropic panels.
A ship's frames are exposed as it is broken near Chittagong, Bangladesh Ship frames visible in an old wooden ship skeleton; Omiš, Feb 20, 2012. In ships, frames are ribs that are transverse bolted or welded to the keel.
A slab deck is one where the deck is analyzed as a plate. If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck. A beam and slab deck is one where the beams may deflect somewhat independently, and any transverse forces are carried in the deck. A cellular ...
