Fishing boats are used in capturing or collecting aquatic resources. As a means of production, the boat should meet various conditions of seaworthiness i.e. good stability, good seakeeping ability and minimum resistance. Those criteria can be identified when the boat size and the hull form are designed. This study investigates the effect of the boat dimension and the hull form on the stability, resistance and seekeeping ability. Various sizes and hull shapes of a 20 GT fishing boat were simulated, and their performances were compared to the IMO standard. The results suggest that the minimum breadth (B) - draft (d) ratio which meets the stability criterion is 2.50, while the ratio of the center of gravity distance from the keel (KG) and the depth (D) of the boat is 0.65. Furthermore, for the boat with a higher B and D ratio, its resistance is relatively smaller. In terms of seakeeping ability, particularly roll and pitch motions, U type bottom performed better than the Akatsuki bottom. Keywords: fishing vessel, sea keeping, ship hull, stability, resistance

Fishing vessels used to catch resources from the sea has to pass some of the regulations from International Maritime Organization for sea-worthiness of the vessel especially about stability, resistance to acquire the highest velocity, and the vessel’s motion. This research discusses the effect of the vessel’s dimension and the hull shape by using the stability standard from IMO.The result shows that the ratio of the B/T which meets the stability criteria is 2.50 with the ratio of KG/H of the vessel is 0.65, with the assumption that the KG and H of the vessel are more than 0.70. Whereas if the resistance ratio B/T is big, the resistance for the vessel will be relatively smaller. In terms of the vessel motion, a vessel with a V-type hull will better than a U-type hull in seakeeping.

⎯ the fishermen's dependence on fossil fuels is still very high at 95.4% and has not decreased until now. The increased fuel price and reduced fossil fuel availability make fishermen struggle to fish. IMO (International Maritime Organization) noted that around 277 million tonnes of fuel are consumed by ships with fossil fuels. According to an emissions study conducted by IMO, 961 million tonnes of CO2 accounted for 2.5% of global emissions. This study aims to reduce exhaust emissions by vessels from fossil fuels by making the ship into a hybrid (Diesel-Pv). Making the ship a hybrid with solar panels will save fuel consumption. The method used is the trozzi method approach. The results obtained from changing the configuration to a hybrid can reduce the issued emission by around 57%.

The fisheries industry continues to be one of the main contributors to economic growth. The Ministry of Maritime Affairs and Fisheries Republic of Indonesia reports that the total capture fisheries production rises every year. In 2016 it was recorded to produce 6.83 million tons. Comparison of safety records from the fishing industry with other industrial sectors shows that it continues to be the most dangerous occupation with a sizeable margin. The safety and efficiency of fishing vessel fleet activities is highly dependent on the quality of management decisions. The causal relationships from accidents involving fishing vessels are identified through an analysis of emergencies and fishing incidents. The purpose of this study is to improve the safety of shipping by applying the risk of accidents of fishing vessel by using Formal Safety Assessment (FSA) methodology. The result show that Mechanical failure has a highest risk followed by Vessel Foundering, Falling Overboard and Other. With the right control measure the cost can be minimized 10 – 50 %. The cause of accident is caused by human factor. Increasing the safety of the shipping is necessary with increase the competence of human and law enforcement of shipping activities especially.

Tanjung Perak Port is one of the main ports in Indonesia that serves the distribution of goods in eastern Indonesia, with increasing sea transport activities at the port. It is necessary for the shipping access channel to accommodate these activities. The Surabaya western access channel (APBS) has been done revitalization of course will be more vessels that will cross APBS, the number of ships that cross the access channel will certainly cause the risk of a cruise accident, for that need to be done review for mapping the risk of accidents in the Surabaya western access channel. The purpose of this study is to improve the safety of shipping by applying the risk of accidents in APBS by using Formal Safety Assessment (FSA) methodology. The results of the study show the causes of accidents before the revitalization is 40 cases of accidents while the accident that occurred after the revitalization is as many as 18 cases with the most causes of human factor. Increasing the safety of the shipping is necessary with increase the competence of human and law enforcement of shipping activities in the APBS.
