Abstract

In order to examine the motions of purse seiner in wave, the measurements of ship motions during fishing operation and during seakeeping trials were carried out using an actual purse seiner, 116GT type. The items measured are rolling and pitching angles. These angles were obtained using a vertical gyro and recorded on a "Visigraph" recorder. The ship motion measurements were carried out during a series of trial runs each of which lasted for 5 minutes with the ship at a speed of 8kts and five headings to the dominant wave direction. On the other hand, the measurements and records of ship motions during fishing operation were continued from the start of shooting purse seine net to the end of hauling net, together with recording the states of net and ship heading. All of these recorded data were used for statistical and spectrum analysis by applying time series procedure.
