Ship arrangement structure of long-line fishing system and operation method of ship arrangement structure

Abstract

The invention discloses a ship arrangement structure of a long-line fishing system and an operation method of the ship arrangement structure. The ship arrangement structure of the long-line fishing system comprises an investigation ship, an open-air operation area is arranged at the tail of a main deck of the investigation ship, a superstructure is arranged on the front middle portion of the maindeck, a rear end wall is arranged at the rear end of the superstructure, and the rear end wall is located behind the middle of the ship. A long-line fishing system is installed in the open-air operation area and structurally comprises a rope throwing machine and a rope collecting machine which are arranged in a spaced mode, and a three-way guide wheel is arranged on one side of the rope throwing machine. A plurality of dry rope winding conduits and a plurality of one-way guide wheels are arranged on a route between the rope collecting machine and the rope throwing machine and a route between the rope collecting machine and the three-way guide wheel, and dry ropes penetrate through the two routes. A power positioning system control station is further arranged on the open-air operation area,arrangement is comprehensive, the utilization rate is high, and the system is suitable for medium-large fishery resource investigation ships with the length being 50 m or above.

Description

technical field [0001] The invention relates to the technical field of ship general arrangement, in particular to a ship arrangement structure of a longline fishing system and an operation method thereof. Background technique [0002] Fishery resource survey ships refer to ships that specialize in scientific surveys of fishery resources, fisheries and fishery water environment, or experimental research on fishing gear and fishing methods. Fishery resource survey ships are generally equipped with necessary equipment such as marine biological sampling, environmental observation and trial fishing gear according to their functional requirements. [0003] Longline fishing is the main operation method in fishing tackle. It is generally suitable for sea areas with vast fishing grounds and slow currents. It is mainly used to catch fish with high economic value such as bluefin tuna and yellowfin tuna. Fishery resource survey ships at home and abroad are generally equipped with a var...

AI Technical Summary

Problems solved by technology

[0005] This arrangement method is relatively simple and suitable for professional longline fishing boats or small-scale fishery resource survey vessels with only deckhouses, but for medium and large fishery resource survey vessels with a length of more than 50 meters, generally the operating deck There is a superstructure in the middle and front part of the ship. If the traditional arrangement method is adopted, it is necessary to install a dry rope reeling guide and guide wheel device from the bow to the stern on one side of the superstructure, which requires a large channel on the side. Opening, which not only destroys the integrity of the superstructure and affects the overall appearance, but also greatly compresses the space of the internal cabins of the superstructure, affects the overall layout of the internal functional cabins, and even makes other fishery resource investigation functions impossible to realize. The gain outweighs the gain
