Sungkur rolling ship with pushing operation method for fish and shrimp catching in the coastal waters

Abstract

Sungkur ship is used to catch fish and shrimp in the coastal waters of Tanah Laut Regency. The ship is operated actively in a push manner. This research aimed to: (1) Analyze the Sungkur ship enforcement arm during the fishing operation (2) Analyze the Sungkur rolling ship movement in regular wave beam seas conditions. The research was conducted in March-May 2018. The research used an experimental method of the fishing operation. Analysis of data through simulation and numerical using naval architecture formula and the results interpreted descriptively. Equipment that is used includes Sungkur fishery, camera, stationery, measuring instrument, water pass, slide, yarn, pendulum, GPS, stopwatch and computer. The results of study showed that the main dimension value ratio of sample ship L/B = 4.68-7.0, L/D = 5.0- 1.2, and B/D = 1.0-2.0. GZ enforcement arm during operation of the Sungkur ship was above the minimum standard value that has been set IMO that is equal to 0.675. Rolling highs at 14.4° with a wave height of -0.46 m and the lowest rolling at -14.4° with a wave height of 0.46 m.
