In the field of transportation, ship is relatively cheap then others transportation. However, the ship still has constraints on speed and fuel consumption. Therefore, the ship has many variations of shape to achieve optimal condition. For example the body of ships with double hulls (catamaran) or three (trimaran), that using foil to make ship can have a smaller resistance to achieve optimal efficiency. The purpose of this research in order to plan the maximum foil shape which can produce high force of buoyance on the catamaran boat (25 meters) and also to determine the type of hydrofoil that produces maximum buoyance force using CFD method.

One type of ship propeller is a ducted propeller. Ducted propellers are propellers with sheath or duct that can increase thrust on the propeller and useful for directing the flow of water that will pass through the Propeller. In addition to improving thrust, ducted propellers can also increase torque compared with no duct. The basic theory of momentum for this ducted propeller operation has been used by Horn (1940). In order for the efficiency of the thrust to be of good value, the volume of water passing through the propeller should be as large as possible, with the smallest possible flow velocity. The most important components of ducted propeller are Ld / D and tip clearance. Ld / D is a coefficient comparison between the length of the casing / duct and the diameter of the duct, while the tip clearance is the distance between the tip of the propeller with an inner diameter of the duct. Both components are discussed in this study. The purpose of this research is to know the performance of propeller after given variation on Ld / D and tip clearance. The method used for propeller analysis is Computational Fluid Dynamic (CFD). Based on simulation result, the most optimal propeller performance is ducted propeller with Ld / D = 0.5 and tip clearance 40 mm

Global Warming is the most compelling environmental issues in the world recently. Almost a century, the temperature increased 0,74° Celsius and made the ice in North and South Pole melt in high rate.Some people say that global warming brings the negative effect for the society, however businessman, especially in shipping and logistic industries, believe that the melting ice process will shorten the distance between East Asia Countries and European Countries. Melting ice in Arctic Sea, open a new route, called Northeast Passage. Using Northeast Passage will reduce distance and time of the voyage.The big idea of this thesis is to compare 2 routes between Northeast Passage and Suez Canal for delivering cargoes from East Asia countries to European Countries or vice versa. Comparing total resistance, total fuel consumption and total cost for bunkering and additional charges are the main topic on this bachelor thesis.Results of this research, total fuel consumption for conventional route is 5810,231215 tons with operational hours of a vessel is 596,15 hours and the total fuel consumption per hour is 9,74625 tons/hour. By using Northeast Passage, a vessel can reduce 1900 nautical miles or saves 17% from the normal distance. There are 2 methods for calculating the resistance of the ship when passing through ice condition, Lindqvist and Riska method. If a vessel wants to save 20% of their fuel consumption (Lindqvist method: 4621,58 tons; Riska Method: 4670,82 tons) compared to conventional route, a vessel just only save 5% of their operational hour (needs 565,367 hours to travel Northeast Passage). Then, if a vessel wants to speed up and save 11% (528,03 hours) of the operational hour it reduces the saving of fuel consumption to 9% (Lindqvist Method 5270,615 tons; Riska Method 5322,38 tons).Bunkering Plan at conventional route is occurred at Hongkong Port, Port Klang and Piraeus Port with price 463 USD, 460 USD and 467 USD respectively. Suez Canal is controlled by a country so a vessel needs to pay some money for passing through the canal. The total price that needed to be paid for conventional route is 2.997.496,754 USD. Northeast Passage is considered as International water because there is too much complexity about the declaration. So, there is no taxes for a vessel when passing through the passage. Bunkering is occurred at Hamburg and one of Port in Russsian Coastline with price 447 USD at Hamburg and 400 USD at Russian. 1962466 USD needs to be paid for a vessel passing through Northeast Passage from Hamburg to Hongkong. The usage of Northeast Passage can saves 35% of expense or equivalent to 1035031 USD.

Propeller boss cap fin is one of the efforts to increase efficiency, especially in the field of ship propulsion. boss cap fins propeller or commonly called PBCF is one of the technologies that replace the boss cap propeller technology that first exists. Increasing efficiency can certainly have an impact on fuel consumption. This study will describe changes in efficiency, thrust, torque and the phenomenon of flow in the propeller after changes in span to chord ratio of fins with a fin form in the form of NACA foil. This research begins with determining the dimensions of the propeller and its model. The next step is to design and draw the boss cap fins propeller by modifying the span to chord ratio of the fins. The final step is analyzing propeller performance with software based on fluid dynamic computation. It is believed that changes in the PBCF span to chord ratio can improve efficiency, thrust, propeller torque, and minimize the hub vortex Simulations are carried out on four variations of the span to chord ratio, namely 0.17, 0.23, 0.29 and 0.34. From this study, it can be concluded that the propeller boss cap fins can increase thrust, torque, and efficiency, but the changes of span to chord ratio PBCF have not much effect on thrust, torque, and propeller efficiency. Increasing the PBCF span to chord ratio can reduce the hub vortex on the propeller.

This thesis is focusing on how to reduce the NOx emission since it has been an issue in all over the world. An idea that reduced the combustion temperature by integrating an external chamber connected with the combustion chamber as a temporary energy storage. This method is implementing the pressure-temperature law, where the pressure is reduced by expanding the volume that resulted a temperature decreased. The aims of this study were to make a feasibility study of the previous invention, a combustion model simulation and technical drawings design of the external chamber. The simulation model involves an analysis of how the temporary energy stored effected the combustion temperature and calculating the pipeline losses. The results showed that by installing the external chamber, the combustion temperature was reduced significantly by 6.15% for the burn zone and 17.8% for the unburn zone. Furthermore, a comparison of the pipeline heat loss showed that an insulated pipe saved 94.1% more heat energy than the uninsulated. The important factor in designing the external chamber were the spring deflection and piston bore. An analysis shown that the larger the deflection and piston bore, the bigger the pressure drop would be which is why an optimization of those factors were needed.
