Abstract

The fishing vessel is the main vehicle of the fishermen to go to fishing ground and hauling purse seine especially fishing gear. Pinrang Regency ships traditionally built without calculation of naval architecture. Where the purse seine fishing gear in Pinrang Regency has length 330 m nets with a depth of 36 m. The purpose of this research was to examine the main dimension ratio in particular design and static stability of the vessel purse seine in Pinrang Regency. Method of using a case study on two types of vessels have different relative and analyzed by numerical simulation, calculate the ratio of the main dimensions and static stability. The results of this research are the vessels in Pinrang kasko model has the shape of a round bottom and slim body as well as the ratio of the dimensions of the vessels only L/D purse seine LOA 24 m more than the standard reference of vessels (encircling) in Indonesia and on the value of the static stability by the IMO, with a purse seine vessel Pinrang already has a good stability. However, in both types of vessel purse seine size 20 m that has better stability. Keywords: design, fishing vessel, purse seine, stability

Abstract

This is an initial study in order to determain the minimum thickness of FRP (Fiber Reinforced Plastic) lamination on the size of a wooden vessel 5–7 GT (Gross Tonnage). The construction of FRP lamination aims to reduce direct contact of some parts of the ship with surrounding water and to reduce collision impact during berthing process as well especially to the hull. The laminating process is carried out by the skilled boat builders based on their experienced and knowledge. The purpose of this study is to obtain the collision strength of the ship that can be used as a refrence to determine the minimum thickness of FRP lamination. The descriptive-numeric methods were used in this research. Some data of the sampled vessel such as vessel type, main dimensions, speed and impact power were needed to be analyzed. There were 13 sampled vessels used in this research. The result showed that the vessel was included to towed or dragged gear. The main dimension of the vessel in average were Loa 9.5 m; Bmax 3.2 m; D 1.2 m with displacement tonnage 13,6 ton/m3. The speed of the vessel decreased since the first collision in range of 0.4-1.0 m/s or 20-75%. The collision strength on that time was in range of 7.13-87.48 kN.m. Therefore, the impact strength that will be used as a reference in determining the thickness of the FRP laminate layer on wooden vessels is 87.48 kN.m.
