Ship body and deep V-shaped bevel half-small waterplane area catamaran

Abstract

The invention discloses a hull and a deep V-shaped bevel half-small waterplane area catamaran, and belongs to the technical field of ships. The ship body comprises a double-piece body, a first anti-rolling bilge keel and a second anti-rolling bilge keel, the longitudinal section of the bottom of the first submerged body and the longitudinal section of the bottom of the second submerged body are of a V-shaped structure, and the first anti-rolling bilge keel is arranged on the side, away from the second submerged body, of the first submerged body in a protruding mode. The first anti-rolling bilge keel extends in the length direction of the first submerged body; the second anti-rolling bilge keel is arranged on the side, away from the first submerged body, of the second submerged body in a protruding mode, and the second anti-rolling bilge keel extends in the length direction of the second submerged body. The first anti-rolling bilge keel and the second anti-rolling bilge keel are located at the same height and are in bilateral symmetry relative to the hull. And the comprehensive counter-acting force of the first anti-rolling bilge keel and the second anti-rolling bilge keel can force the ship body to be straightened and erected, the wind wave resistance is high, and the seakeeping performance, the seaworthiness and the riding comfort of the ship are improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a hull and a semi-small waterplane area catamaran with a deep V knuckle. Background technique [0002] With the rapid development of offshore wind power construction, the cumulative total installed capacity has increased year by year. From the initial offshore wind farm to the continuous deepening of offshore wind farms, its scale, output and demand for marine transportation have also grown rapidly. Offshore wind power operation and maintenance ships also developed rapidly. However, the existing ship types cannot fully meet the growing operation and maintenance needs of offshore wind farm developers, owners and operators for newly built wind farms. [0003] The overall development momentum of domestic wind power operation and maintenance ships is very rapid. From simple speedboats, traffic boats, and tugboats used very close to the shore, to special single-body steel operation an...

Problems solved by technology

However, in the existing technology, steel low-speed operation and maintenance ships are still mainly used, with a speed of about 10 knots, while high-speed double-hull aluminum alloy operation and maintenance ships have gradually developed to a high speed of about 25 knots, but the overall The anti-wave height capability of personnel transportation on board is about 2 meters, and it is still in the technical state of a coastal and near-shore ship type.

[0004] Ships at this stage have low wind and wave resistance and poor passenger comfort, which makes them very prone to seasickness
