Shipyards: concept and classification
Shipyards are the land-based facilities where ships are repaired and built. In a shipyard, all types of ships can be repaired or built, either for the transport of passengers or for the transfer of goods. From large commercial ships to ships for military use, through yachts and pleasure boats, all aquatic vehicles that have a certain structure are born in shipyards. Shipyards are built next to rivers or navigable seas. In this way the access of boats to the place and their exit to the waterways is facilitated. Typically, a shipyard has a limited number of building berths, sloping towards the waterway, with large adjacent work areas. Very large ships are often built in deep dry docks due to the greater convenience of lowering large components. When the hull is complete, water is admitted and the boat floats to the conditioning dock.
As a general classification, we can classify shipyards into two different types:
- Construction shipyards: The construction shipyard is that establishment which focuses its business activity on the construction of boats. Ship building is a complicated and highly technical process, requiring the coordination of numerous permanent and casual workers under the control of the prime contractor. Shipbuilding can be of a civil or military nature.
- Repair shipyards: The repair shipyard bases its business line on the repair of boats and / or floating devices. All ships are not the same, therefore, consequently, the shipyards where repairs are carried out are not the same either, which is why they are usually specialized in a specific group or type of vessels.
In 2016, the ten shipyards in the world with the largest order book were seven South Koreans, two Chinese and only one Japanese. The Ulsan shipyard, in South Korea, is currently the largest in the world, leads the shipbuilding with an annual share of 15% of the market, this shipyard extends along four (04) kilometers of the coast of the Mipo Bay, has nine large-scale dry docks, the largest being 460 meters long with a width of 135 meters, it also has seven (07) large “Goliath” cranes with a load capacity of 3,150 tons and one hundred (100) meters high to build a wide variety of vessels and with an effective production of one (01) week of delivery. By the end of June 2010, Hyunday Heavy Idustries had delivered more than 1,562 vessels to 253 different shipowners in 47 countries. More than 60,000 people work at the Hyundai shipyard, at a rate of producing a huge ship every four to five days.
