The main purpose of this thesis is to examine the relationship between the hull of the vessel in regard with the fuel consumption. The structure of the hull, the material that the hull is built, the time that took the designer to design the hull. How can a hull be perfect for each voyage ? how important is the place where a vessel is trading in relationship with the hull type? The reduction of the ships fuel consumption and and how can a vessel achieve it. Fuel consumption is very crucial in the economic part of the vessel during its short term or long term life and each knot plays a role. Ship owners can pay for better paints in their hulls that wont allow micro organisms to appear and reside on the vessels hull and propeller. They can also ask from companies to clean the hull of their vessels with new technologies or diver, which is called underwater hull cleaning. Does this helps them economically and with the vessels speed and consumption? The speed of the vessel is also affected by the emissions and how much the vessel is harming the environment with CO2. Kamsarmax bulkers, new type of bulkers that are being ordered massively and are trading and preferred by the ship owners because of their specification. We are going to see real data from a Kamsarmax vessel about its speed, its consumption and the engine hours before and after the underwater hull cleaning. Aframax tankers, also known as “Dirty Tankers” the answer to the traffic due to the VLCC’s and blocking the routes. How they are used in the Mediterranean and Africa. We are also going to analyze data regarding its speed, its consumption and the engine hours before and after the underwater hull cleaning.
