The Amalgamated Society of Boilermakers, Shipwrights, Blacksmiths and Structural Workers (ASB) was a trade union in the United Kingdom. Many of its members worked in shipbuilding, in which industry it was the leading trade union, while over time it also developed strength in engineering and construction.
The ancient writers Polybius and Plato held that, since the ribs of a ship were the most important part of the ship's framework, then if the ribs were new, then the ship as a whole was new. [3] Iron was first used in shipbuilding to make the ribs and frames, with wood sheathing attached to them, but this proved inadequate compared to replacing ...
A structural keel is the bottom-most structural member around which the hull of a ship is built. The keel runs along the centerline of the ship, from the bow to the stern . The keel is often the first part of a ship's hull to be constructed, and laying the keel , or placing the keel in the cradle where the ship will be built, may mark the start ...
Reconstruction of a 19th-century naval architect's office, Aberdeen Maritime Museum General Course of Study leading to Naval Architecture degree Naval architecture, or naval engineering, is an engineering discipline incorporating elements of mechanical, electrical, electronic, software and safety engineering as applied to the engineering design process, shipbuilding, maintenance, and operation ...
On ships with more than one level, 'deck' refers to the level itself. The actual floor surface is called the sole; the term 'deck' refers to a structural member tying the ship's frames or ribs together over the keel. In modern ships, the interior decks are usually numbered from the primary deck, which is #1, downward and upward.
Structural engineers often specialize in particular types of structures, such as buildings, bridges, pipelines, industrial, tunnels, vehicles, ships, aircraft, and spacecraft. Structural engineers who specialize in buildings may specialize in particular construction materials such as concrete, steel, wood, masonry, alloys and composites.
Many ships endure cold winter storms, and the use of some older ship steels that were not tough enough at low temperature caused ships to crack in half and sink in the Atlantic during World War II. The benchmark steel grade is ABS A, specified by the American Bureau of Shipping. This steel has a yield strength of at least 34,000 psi (230 MPa ...
A ship classification society or ship classification organisation is a non-governmental organization that establishes and maintains technical standards for the construction and operation of ships and offshore structures. Classification societies certify that the construction of a vessel complies with relevant standards and carry out regular ...
