A ship arrangement structure of a longline fishing system and its operation method

Abstract

A longline fishing system ship layout structure and operation method thereof, including a survey ship, an open-air work area is provided at the tail of the main deck of the survey ship, a superstructure is provided at the middle and front part of the main deck, and the rear of the superstructure is A rear end wall is arranged at the end of the ship, and the rear end wall is located behind the middle of the ship; a longline fishing system is installed in the open-air work area, and the structure of the longline fishing system is: including a rope throwing machine and a rope taking machine arranged at intervals, A three-way guide wheel is arranged on one side of the rope machine, and multiple dry rope winding guides and multiple one-way guide wheels are arranged on the route between the rope take-up machine and the throwing machine and between the rope take-up machine and the three-way guide wheels. On the route, both routes pass through the dry rope; the open-air operation area is also equipped with a dynamic positioning system control station, which is comprehensively arranged and has a high utilization rate, and is suitable for medium and large fishery resource survey ships over 50 meters in length.

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
