Welded steel plate forming part of a ship's hull. Automatic flame cutting of steel plate in fabrication shop.įigure 4. These shapes may be then welded together to form I and T beams and other structural members (see figure 4).įigure 2. Typically the plates are cut by an automatic flame cutting process to various shapes. The plates are cut, shaped, bent or otherwise manufactured to the desired configuration specified by the design (see figure 2 and figure 3). The basic component of ship building is steel plate. In addition, environmental issues must be addressed. In the design phase, not only should normal construction parameters be considered, but the safety and health hazards associated with the construction or repair process must be considered.
Ships may transport materials or people, may be surface ships or subsurface, may be military or commercial and may be nuclear or non-nuclear powered. The design considerations for various types of ships vary widely. Overview of the Ship Construction Processįigure 1 gives an overview of shipbuilding. Further, this type of construction lends itself towards automation and robotics, not only saving money, but reducing exposures to chemical and physical hazards. This process is faster, less expensive and provides better quality control. Thus, the modules may be relatively easily connected. However, advances in technology and more detailed planning have made it possible to construct the vessel in subunits or modules that have utilities and systems integrated within. Formerly, most construction took place in a building or graving dock, with the ship constructed almost piece by piece from the ground up. Shipbuilding has changed radically since the 1980s. It is an international business, with major shipyards around the globe competing for a fairly limited amount of work. Shipbuilding is performed for both military and commercial purposes. It involves the blending of many skilled trades and contract employees working under the control of a primary contractor.
The construction of a ship is a highly technical and complicated process.
