Shipbuilding is generally carried out in the slipway or dock of a professional facility shipyard. The technology used in shipbuilding itself is very extensive. From the hull to the use of engines, shipbuilding technology can be divided into several categories, including the hull.
This part is mainly based on basic design and structural design, which can be subdivided into steel ships, aluminum alloy ships, glass fiber reinforced plastic (FRP) ships, cement ships, wooden ships, leather ships, plastic rafts and so on. ), outfitting (such as electronic equipment, navigation equipment, furniture, equipment other than the host, etc.). ), as well as marine engines (such as steam turbines, gas turbines, diesel engines, nuclear engines, etc. ).
Hull lofting:
Linear lofting: can be divided into manual lofting and machine (computer) lofting. Generally, manual lofting is 1: 1. The sample table needs to occupy a huge area and needs a lot of manpower and material resources, so it is rarely used.
Machine lofting, also known as mathematical lofting, depends on advanced technical software to lofting the hull, which has high precision and does not occupy space and manpower, so machine lofting is widely used.
