Description

Linear structure of work catamaran {SHIP-STRUCTURE OF WORKING CATAMARAN}

The present invention relates to a linear structure of catamarans, and particularly, it is a medium and low speed catamaran for securing stability and stability such as stability and piercing when sailing, and to ensure safety and convenience when working at sea. It relates to a catamaran linear structure configured to be suitable to ensure the stability of the.

Catamaran, as shown in Fig. 1, refers to a ship that connects the two hulls to a deck or other structure so that the two hulls share a relatively small amount of drainage, and when the necessary amount of water is divided into two, the hull becomes thinner. As a result, the wave resistance decreases, which is advantageous.However, the total submerged surface area of the two hulls increases, which is disadvantageous for frictional resistance, which is often used in high-speed ships where the wave resistance occupies a large proportion. As a result, a large deck area can be obtained, and the overall ship's width is increased, so it is also highly resilient, which is advantageous for work ships and survey ships that require a large area such as passenger ships or marine probes.

These catamarans have a special purpose minimum water surface area catamaran (SWATH) .The principle of such catamarans is due to static buoyancy, like ordinary catamarans, but most of the displacement is submerged in the water surface and the deck deck hull and subsurface cylinder It consists of a lower hull and a thruster connecting it.

The advantage of this linearity is that it can maintain high speed even in a large wave due to its excellent resistance to waves, and it has less repair area and less resilience when trimming. In addition, there are complex catamarans.

As a conventional technology, as shown in Figure 2, there is a 'all-weather long-distance high-speed catamaran, or Dadong line' of the application No. 1990-20003 (1990.12.06) filed in Korea by H Heavy Industries Co., Ltd. The hull (1, 1 '), the connecting portion (2) and the arc (3, 3') are all curved, and in particular, the central blade (4) of the connecting portion is not only difficult to design and manufacture, but also error in production There is a problem in that the production period is also required for a long time, the high cost of drying costs and the long drying period.

The present invention has been proposed to solve the conventional problems as described above, the purpose of the present invention in the catamaran vessel for work, while ensuring the stability performance and the sailing performance of the ship, such as to straighten the fuselage and the connecting portion of both sides as much as possible In addition to simplifying the design and manufacturing process, it is to provide a linear structure of a catamaran that has a straight-body body that can build a ship at low construction costs by minimizing errors due to manufacturing and shortening the production period.
