Abstract

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

Abstract

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.

Abstract

In Indonesia, many fishing vessels are made from generation to generation in a traditional way. As a result, the ships built did not comply with the regulations and permits of the naval architects. The fishing industry is one of the most dangerous because it works on the high seas. Therefore the performance in hydrodynamics and safety should be evaluated on these traditional vessels. The main objective of this research is to evaluate the hydrodynamic performance and safety of fishing vessels. Following standard specifications or criteria, seakeeping performance is evaluated using Maxsurf Ship Design software. Assessment of existing safety equipment uses IMO (International Maritime Organization) regulations and the Torremolinos protocol. As a result, the ship can only operate at a wave height of 0,1-0,5 meters or undersea state 3. Ship safety inspections reveal that they still do not meet the required requirements and do not have the necessary equipment specified by the World Maritime Organization (IMO).

Abstract

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%.

Abstract

The purpose of this study is to analyze the effect of laying solar panels on the deckhouse of small fishing vessels 30 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 measuring the wave characteristics using the JONSWAP method 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 agreed to the IMO standard criteria. Moreover, the success of the fishing operation will be more visible if the vessels operated on waves under 2 meters due to the more stable movement according to its seakeeping performance .

Abstract

FPSO (Floating Production Storage and Offloading) is a moving floating structure to accommodate petroleum exploration results with a frequently used mooring system, namely spread mooring. To make it easier for the FPSO ship to not be able to rotate or even move when loading and unloading due to environmental influences, a spread mooring mooring system is needed with analysis of the mooring stress and anchor lifting force that occurs on the FPSO ship. To determine the anchor lifting power and tension on the mooring, the RAO formula is needed using the Jonswap method, which will give RAO results in response to environmental influences. In this case, the Jonswap method is used to determine matters related to the RAO response to environmental factors by analyzing the FPSO ship model from Maxsurf software, then continuing the analysis using Ansys software. From the RAO response we get the mooring tension and anchor lifting power to the influence of environmental forces. The results of the mooring spread analysis obtained the highest stress value of 6.141 x 105 N, with an anchor lifting force of 4.717 x 103 N.

Abstract

This research was carried out with the aim of measuring the effect of the body on the fluid flow that occurs around it and measuring the stress that occurs in the ROV AF-150114 design. The research method uses software with a CFD model approach to analyze the stress that occurs in the designs made. In general, there are three stages that must be passed in a CFD simulation: Pre-processing. Solving and post-processing. What is calculated is the velocity, viscosity and pressure of the water flow around the ROV body. The results obtained show that the balance of the ROV body greatly affects the ability to dive and maneuver during maneuvers. The highest pressure/pressure for fluid flow occurs at the ROV AF-150114 speed of 2.5 m/s with a value 39,825 Pa and the value of viscosity is 10,860 Nm/s2. ROV AF-150114 movement test results found that the experiment has a faster movement time speed than the calculation.

Abstract

Fishermen heavily depend on fossil fuels, around 95.4%, with no apparent decrease. Rising fuel costs and declining fossil fuel supplies challenge the fishing industry. The International Maritime Organization notes that ships using fossil fuels consume 277 million tons of fuel, contributing 2.5% to global emissions (961 million tons of CO2). TReducing reliance on fossil fuels and adopting alternative sources such as solar energy is suggested to address energy issues in Indonesia; solar energy, with an intensity of 0.6 to 0.7 kW/m2, is considered promising. This study uses an experimental design methodology to evaluate the installation of solar panels on a 20 GT fishing vessel at Muara Angke Port, Jakarta. Primary data, including ship size, was collected from the field. The economic focus is on the payback period, calculated through interviews with the crew. Exhaust gas emissions were calculated using factors established by the Ministry of Transportation. The results indicate that replacing CFL lamps with LED can save energy, specifically around 5 kW on this vessel. The feasibility of installing 14 solar panels is shown, costing over 20 years of Rp. 65,100,000. The payback period is estimated at three years, and the long-term analysis of Photovoltaic Solar Panels (PLTS) over additional engine investment. Cumulative emissions from the engine in one year are 155,007 tons, making PLTS environmentally beneficial without emissions.

Abstract

Addressing global issues like climate change requires transformative solutions, and the shipping industry is no exception. Moving towards emission-free ship design has become a critical need, offering a chance to significantly reduce greenhouse gas emissions from maritime transport. In 2018, the International Maritime Organization (IMO) adopted a bold strategy to cut these emissions by at least 50% by 2050. Embracing renewable energy sources like batteries, wind, solar, and hydrogen fuel cells is key to achieving this ambitious goal. While electric ships powered by batteries are pioneering the way, meeting the IMO's target will necessitate radical changes in future ship design. Here, Indonesia holds a unique advantage, the legacy of the Sriwijaya Empire renowned for its mastery of wind-powered ships, resonates with this emerging era of green shipping. Abundant sunshine, strong wind potential, and growing expertise in maritime engineering position Indonesia to become a leader in the development and deployment of sustainable ship designs. Harnessing these historical and contemporary strengths, Indonesia can play a pivotal role in revolutionizing the shipping industry. By fostering collaboration between policy makers, researchers, and shipbuilders, Indonesia can spearhead the transition to a future where cargo ships navigate the oceans propelled by the clean power of renewable energy, leaving behind a legacy of environmental stewardship and economic prosperity. This paper estimates the energy consumption and power needs of Container ships on short inter-island routes in Indonesia, with a particular focus on the potential application of batteries in such scenarios. The initial design utilizes similar vessel data collected from various locations around the world. Our findings indicate that a container ship operating on the Jakarta-Semarang route would require batteries with a capacity of 15.25 MWh, Semarang to Surabaya route would require 12.20 MWh batteries, from Surabaya-Tanjung Benoa Bali route required 15.25 MWh, from Tanjung Benoa Bali to Ujung Pandang route require 21.35 MWh batteries, all with a capacity of 1.5 MWh each and from Ujung pandang – Ibu Kota Nusantara require 18.3 MWh. These calculations assume normal sea and weather conditions and a design speed of 10 knots. Implementing battery-powered Containers on these routes reduces the CO2 emission into the air as long as the ship route operates.
