deck beam of a ship

a deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-story building, that are also referred to as decks, as are certain compartments and decks built over specific areas of

deck beam: …keel, transverse frames, and cross-ship deck beams that join the frame ends—all supporting a relatively thin shell of deck, sides, and bottom. This structural scheme, which became prevalent with European ships during the Middle ages, has continued into the age of steel shipbuilding. However, it has a significant drawback in…

BOC stands for beam On Centerline. This term in typically used in conjunction with LOa (Length overall). The ratio of LOa/BOC is used to estimate the stability of multihull vessels. The lower the ratio the greater the boat's stability. The BOC for vessels is measured as follows: For a catamaran: the perpendicular distance from the centerline of one hull to the centerline of the other hull, measured at deck level. For a trimaran: the perpendicular distance between the centerline of the main 

The most common place you can see the plate in ship construction is the main deck and side of the ship. beam. a beam is a structural element that increases load bearing capability and avoid bending of the structure. beams can be categorized by many types but from point of ship construction, we need to categorize it through cross sectional shape. For example, there are But we have to understand that all these structure will be a form of plate, bar or beam.

deck-beam: a strong transverse beam of timber or iron stretching across a ship from side to side, in order to support the deck and retain the sides at their proper distance.

In shipbuilding, carlings are two pieces of timber laid fore and aft under the deck of a ship, from one beam to another, directly over the keel. They serve as a foundation for the whole body of the ship; on these the ledges rest, whereon the planks of the deck, and other structures are fastened. The ends of the curlings are let culvertail into the beams. The great carlings are those on which the mainmast stands. There are also carlings of the capstan, among others. Carling knees are timbers 

These are secured at the lower end to the keel or center keelson and at the upper ends to the deck beams. They are in two parts called floors and side frames and, while necessary, subtract from cargo space inside the ship. Longitudinal strength comes from the keel, keelson, intercostals (also called longitudinals), tank top and decks to resist stress caused by the rolling forces of the sea. The side plating also takes much of this stress. If there were insufficient longitudinal strength, the

The forward end of the ship is called the bow, the after end is the stern, and halfway between the two is amidships. The beam of the ship is the distance between the two ship's sides.

The large timbers that sit on top of each rib as they extend up from the keel span the whole width of the ship for strength. On top of this was a deck made of smaller boards that also acted as the ceiling for the first level cabins. From the inside, the ship resembled a house with its floor beams and exposed underside floor decking. a common way to talk about a ship was by the size of her roof beams which would tell you how wide the vessel was and how that proportion 

There are two types: beam, Overall (BOa), commonly referred to simply as beam- The overall width of the ship measured at the widest point of the nominal waterline. beam on Centerline (BOC) - Used for multihull vessels. The BOC for vessels is measured as follows: For a catamaran: the perpendicular distance from the centerline of one hull to the centerline of the other hull, measured at deck level. For a trimaran: the perpendicular distance between the centerline of the main hull and 

Frame type and spacing vary considerably depending on the ship's construction. Shell framing. Shell framing. deck beams: These are transverse members that connect the top ends of the frames, forming the transverse framing for the deck. Longitudinal framing, deck and shell. Longitudinal framing, deck and shell. deck girders: These are longitudinal members that combine with the beams to form the longitudinal framing of the deck. Longitudinals: a very general term to identify any 

The camber is a measure of lateral main deck curvature in naval architecture. The curve is applied to a deck transversely, measured as the height of deck at centreline above the height of deck at side. The practice of adding camber to a ship's deck originated in the era of small sailing ships. These vessels were built with the decks curving downwards at the sides in order to allow water that washed onto the deck to spill off. It adds to the ship's longitudinal strength also.

Length on Waterline (LWL): This is the length at the waterline in the ship's design loaded condition. Freeboard (F): Distance between the waterline and the uppermost watertight deck. Sheer: The rise of a deck - usually toward bow and stern. Sheer increases freeboard, and helps keep the vessel from shipping water in rough seas - particularly at the bow.
