“…Another interesting study was conducted by Park, where they researched the shipboard noise caused by the sailors hitting the hull with metal bats or the engine idling during a fishing operation involving attracting anchovies to the surface with a fishing lamp in a 6-ton FRP vessel near Jeju Island of South Korea [23]. However, this was a very special case of subminiature fishing vessels belonging to local fishermen of a traditional fishing background, meaning that this case is somewhat irrelevant to our research.…”

In this study, we conducted onboard noise measurement experiments under the conditions of anchoring, sailing, casting, and hauling to determine whether noise generated in the G/T 1000-ton fishing trawler triggers zone-specific effects upon vessel operation. It was shown that most accommodation areas of the trawler comfortably met the IMO acceptance criteria regardless of the sailing condition, but most of the stern area, where the fishing actually occurs, exceeded the permitted limit of 75 dB (A). Furthermore, the statistical analysis revealed a significant difference (p < 0.05) only in the bow and the stern, which are both open areas. In the case of the former, improvements were deemed possible due to the influence of the fluid emission noise from the seawater piping in the bow, and the acceptance criteria were also appropriate. However, in the case of the latter, a significant difference was seen in hauling conditions, and on-site analysis confirmed frictional noise from hydraulic oil in the trawl winch and between the chains and the metal hull, leading to the conclusion that various improvements are required, such as the mandatory wearing of safety equipment by workers and stricter legal standards for permitted noise levels.
