Free Woodworking Plans & DIY Wood Project Ideas Shipbuilding is the construction of ships and other floating myboat044 boatplans normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history.. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". This was done using steamers and wood as fuel. Planks were heated up to be able to bend with the curve of the ship. Once all the framing and planking was completed, caulking waterproofed the ship. Ships made of wood required a flexible material, insoluble in water, to seal the spaces between planks. Pine pitch was often mixed with fibers like hemp to caulk spaces which might otherwise leak. Reference Document: Modern Shipbuilding Terms F. Forrest Pease, J. B. Lippincott Company This glossary gives definitions of many (but by no means all) of the ship/boat construction terms the marine surveyor will find. They relate to the hull only and are mainly those that the author learned when he was an apprentice shipwright.

In the great days of sail , vessels were designed and built on the basis of practical experience; ship construction was predominantly a skill. The consequence of this was a rapid increase in the size, speed, commercial value, and safety of ships.

He is usually required to prepare a design for a vessel that must carry a certain weight of cargo or number of passengers at a specified speed with particular reference to trade requirements; high-density cargoes, such as machinery, require little hold capacity, while the reverse is true for low-density cargoes , such as grain.

Deadweight is defined as weight of cargo plus fuel and consumable stores, and lightweight as the weight of the hull, including machinery and equipment. The designer must choose dimensions such that the displacement of the vessel is equal to the sum of the deadweight and the lightweight tonnages. The fineness of the hull must be appropriate to the speed. The draft�which is governed by freeboard rules�enables the depth to be determined to a first approximation.

After selecting tentative values of length, breadth, depth, draft, and displacement, the designer must achieve a weight balance. He must also select a moment balance because centres of gravity in both longitudinal and vertical directions must provide satisfactory trim and stability.

Additionally, he must estimate the shaft horsepower required for the specified speed; this determines the weight of machinery. The strength of the hull must be adequate for the service intended; detailed scantlings frame dimensions and plate thicknesses can be obtained from the rules of the classification society. These scantlings determine the requisite weight of hull steel. The vessel should possess satisfactory steering characteristics and freedom from troublesome vibration and should comply with the many varied requirements of international regulations.

Possessing an attractive appearance, the ship should have the minimum net register tonnage , the factor on which harbour and other dues are based. The gross tonnage represents the volume of all closed-in spaces above the inner bottom.

The net tonnage is the gross tonnage minus certain deductible spaces that do not produce revenue. Net tonnage can therefore be regarded as a measure of the earning capacity of the ship, hence its use as a basis for harbour and docking charges. Passenger vessels must satisfy a standard of bulkhead subdivision that will ensure adequate stability under specified conditions if the hull is pierced accidentally, as through collision.

Compromise plays a considerable part in producing a satisfactory design. A naval architect must be a master of approximations. If the required design closely resembles that of a ship already built for which full information is available, the designer can calculate the effects of differences between this ship and the projected ship.

If, however, this information is not available, he must first produce coefficients based upon experience and, after refining them, check the results by calculation. The wooden ship was constructed on a building berth, around which timbers and planking were cut and shaped and then fitted together on the berth to form the hull. A similar practice was followed with iron vessels and, later, with the earlier steel ships, as these tended to be replicas of wooden hulls.

Gradually iron came to be used more effectively in its own right, rather than as a substitute for timber. The berth or slipway from which the vessel is launched is an assembly area, rather than a ship construction site. In many shipyards the number of launching berths has been reduced to increase the ground area available for prefabrication sheds.

Greater ease of fabrication means that, despite the reduction in the number of berths, more ships can be built and construction costs lowered. A shipbuilder undertakes to deliver to the client by a certain date and for a stated sum a vessel with specific dimensions, capabilities, and qualities, a vessel that has been tested on trial and is ready for service.

The raw materials for construction and finished items to be installed on board are delivered there. The labour force in the yard consists of various workmen�steelworkers, welders, shipwrights, joiners, plumbers, turners, engine fitters, electricians, riggers, and painters. Volatile Organic Compounds finishes, stains, and inks which are environmentally responsible products that deliver beauty and protection, while meeting the most stringent environmental regulations.
