[0003] At present, no patent on this seine boat has been retrieved, although there is a Chinese utility model patent "A Steel Fishing Boat Hull" with a patent number of ZL95223253. Hulls with large size and good seakeeping performance are suitable for oceangoing sailing, but the drag reduction performance, propulsion performance and stability performance can be further improved

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 , 2 Shown is a preferred embodiment of the present invention.

[0018] A high-performance ocean-going tuna seiner, comprising a hull 1, the total length of the hull 1 is L93 meters, and the square coefficient is 0.58. The square coefficient is the displacement volume under the waterline and the corresponding length, width and draft of the waterline. The ratio of the cuboid volumes represented by the product.

[0019] The stern of the hull 1 is provided with a stern shaft 2, on which a propeller 3 is installed, and the bow of the hull 1 has a bulbous bow 4 extending forward, the bulbous bow 4 is located below the waterline of the bow of the hull, and the bulbous bow 4 It is flat and streamlined, and the length L1 of the bulbous bow 4 is one-twentieth of the total length L of the hull. The head wave generated by the b...

Abstract

The invention relates to a high-performance deep sea tuna seine ship, comprising a ship body (1); the tail of the ship body (1) is provided with a tail shaft (2) provided with a propeller (3); the high-performance deep sea tuna seine ship is characterized in that the head part of the ship body (1) is provided with a ball nose bow (4) extending forwards; the ball nose ball (4) is positioned below the waterline at the head part of the ship body and is in a flat streamline shape. Head waves generated by the ball nose bow with such a shape and the making wakes of the main ship body can generate favorable disturbance to reduce the wave-making resistance components of the whole ship, the pressure difference resistance components of the head part of the ship can be effectively reduced by the flat streamline shape, energy conversation and emission reduction are realized, the deep sea tuna seine fishing operation efficiency is improved, and the sustainable development of the marine fishery is promoted.

Description

technical field [0001] The invention belongs to the technical field of ship design and construction, in particular to a high-performance ocean-going tuna seine ship. Background technique [0002] Since the United Nations "Convention on the Law of the Sea" was promulgated, the division of the exclusive economic zone of 200 nautical miles has had a profound impact on the development of the world's marine fisheries. The ocean fishery has become the trend of today's international pelagic fishery development. This situation prompts fishing boats to go out to sea. , to seek offshore resources to make up for the shortage of offshore aquatic resources. High-performance large-scale pelagic fishing vessels are the most important hardware conditions for vigorously developing pelagic and offshore fisheries. In the pelagic fishery, the tuna fishery plays an important role. The output of tuna seine fishery in the world accounts for more than 60% of the total output of tuna fishery, and ...
