Description

Catamaran {Ship with twin hulls}

The present invention relates to a catamaran, and more particularly to a catamaran that has a light weight and strong hull and a large durability against wave resistance.

In general, cargo ships carrying cargoes in ports, lakes and canals, or carrying a large amount of construction materials or construction equipment or large container boxes, are not desirable in the sea with high wave resistance, It is relatively poor, and this disadvantage becomes worse as the deck gets larger. In addition, the vessel should be loaded with heavy structures or other cargoes of heavy weight within the width of the deck. As a result, a large load is placed on the submerged hull or deck and is susceptible to wave resistance.

Therefore, a catamaran is required to safely support the transport speed, mobility, adjustability and cargo of the cargo vessel and to work safely on the cargo.

In general, a ship combined on deck with two hulls of the same type at regular intervals is also called catamaran or caterpillar. Caterpillar is a generic term for rafts of two or more bamboo and logs, originally used in Taiwan, Ceylon, and Solomon Islands.

Since catamarans are lined with two hulls, they can interfere with the waves produced by each hull, reducing the wave resistance, so that the speed does not decrease. Moreover, compared with a single acting line | wire, stability is good and the structure part which couples a catamaran can be used widely. In other words, the width of the deck can be wider than the length of the ship, and the passenger ship can have several floors. Catamarans also weigh less than 10,000 tonnes and are lighter than the 40,000 tonnes of a 3000 PEU, a typical container cargo ship, which provides excellent fuel savings and good deck utilization. However, catamarans are limited to cruise ships, small passenger ships, and small cargo ships because they are not suitable for ships with large changes in draft, where the ship's size and weight become problems due to problems in strength. There is a problem.

Therefore, an object of the present invention is to provide a catamaran vessel with reduced weight of the hull and increased durability.

In addition, another object of the present invention is to provide a catamaran that prevents rolling of the hull and is easy to manufacture.
