Minimum Freeboard Design On Safety And Operational Cost Reducing Of A 30 Gt Fishing Vessel In Sulawesi Water (Case Study Of Km Inka Mina 759)

Fishing vessels are generally designed with special missions to locate, capture, and preserve fish, while the vessel must have a good level of safety, low operation costs and environmentally friendly. This study aims to improve the safety level and reduce operational cost of 30 GT fishing vessel through minimum freeboard design. Maxsurf program package has been used in dimension modeling, hull form design, stability and resistance prediction on 4 (four) hull form models analyzed (K-1, K-2, K-3 and K-4). The results show that the hull form of K-2 with the wider dimension ratio (L/B=4.98, B/D=3.26, B/T=4.80, D/T=1.47) has a level of stability better than 3 (three) other hull form models (K-1, K-3 and K-4), while the highest reduction of resistance value is shown by hull form model of K-3 with a slimmer main dimension ratio (L/B=6.43, B/D=2.78; B/T=4.09; D/T=1.47). In general, the four models of hull forms analyzed deserve to be operated in accordance with the IMO criteria.
