어업용 씨앵커의 표준화에 관한 연구

Abstract

Fishery sea anchor is widely used for offshore jigging vessel, large powered purse seiner, distant water jigging vessel and fishing boat. However, standardization of the dimension, material and terms of the fishery sea anchor has not been achieved, which reduces the reliability of the performance and safety of the fishery sea anchor. Therefore, this study suggests the development direction of the standard draft for the improvement of safety and field utilization of fishery sea anchor and the standard of product performance. To this end, this study investigated the actual use of the fishery sea anchor and performed a performance test on the canopy cloth of the sea anchor based on research on the realities of use. As a results of the survey on the reality of usage show that various terms were used for each part of the fishery sea anchor (including incorrect forms of non-standard words derived from Japanese), and the production of this product in the fishery sea anchor market was concentrated on one specific manufacturer. In addition, the main specifications of the fishery sea anchor are set and manufactured based on conventional experience without standards. And in the field, there was no standardized drawing for fishery sea anchor, and users had low awareness of the main specifications of fishery sea anchor. Therefore, this study suggested the following regarding the fishery sea anchor: standard terms for each part including Korean and English names, the length of the base of one width of canopy cloth, standard for the size of cloth width and shroud line length of sea anchor of 9.77 ton class and 29ton class fishing vessel, standard drawing of sea anchor. This study conducted seven performance tests after collecting the nylon fabric, the seam of the nylon fabric, and the yarn used by the manufacturer according to the test method of Korean Industrial Standard in order to propose a standard of performance criteria for canopy cloth that has the most influence on the performance of sea anchor. Based on the test results, this study proposed the minimum tensile strength of canopy cloth under wet conditions: warp of 860N, Weft of 430N. And the minimum seam strength of canopy cloth seam is 900N as performance standard. It is hoped that this study will contribute to the study for standardization of fishery sea anchor, which will lead to the improvement of product performance and increase in reliability, and also will lead to increased interest in standardization in the fishery field.
