Abstract

High stability is imperative, safeguarding against the unpredictable nature of the marine environment and promoting a secure working platform for crew members to do fishing operation. The aim of this study is to analyze the effect of laying solar panels on the deckhouse of small fishing vessels 20 GT. The additional load above which causes weight gain and will affect the ship's center of gravity is became the first effect of Fishing vessel stability. The second effect is on how the fishing vessel performs when there is a solar panel on the vessel. The data were collected by measuring the stability according to A.N Kyrylo’s method with standard checks according to the IMO (International Marine Organization). Code on Intact stability calculated the ship motion by using the STRIP method and using the JONSWAP method to measuring the wave characteristics with the help of Maxsurf software. The results of this research show that the installment of solar panels above the deckhouse does not really affect the stability, where the results were meets the IMO standard criteria. The successful fishing operation of the vessels studied will only have a good performance at 1.5 meters, according to the seakeeping analysis.

Abstract

Lake Sunter, an man-made lake built since the 1970s and covering approximately 33 hectares, is commonly referred to as Lake Podomoro. Positioned as an urban recreational space, its scenic vistas offer potential for diverse water-based activities. In order to increase tourist engagement with the lake, it is imperative to diversify the available attractions. Among these attractions, tourist boats emerge as a viable option to capture public interest. Accordingly, this study attempts to design a catamaran tour boat equipped with motorcycle propulsion, tailored for operation on Lake Sunter. In the first stage, the primary dimensions of the catamaran vessel are determined using the linear regression method, resulting in dimensions of L = 3.2m, H = 1.15m and T = 0.4m, with a passenger capacity of 3 persons. The ship's stability is then assessed in accordance with the criteria of the IMO A.749 (18) Code On Intact Stability, Chapter 3, which applies to all ship designs. This assessment includes Load Case I and Load Case II conditions to determine the stability of the ship under different scenarios.
