Compliance with the new regulation on sulfur content in the fuel used for ships when ships operate in an emission control area can be achieved by using fuel with a sulfur content of 0 0015 at all times of ship operation or switching from high-sulfur fuel to 0 0015 sulfur fuel when the ship enters an emission control area. Fuel switching during the ship operation can present a number of problems related to fuel characteristics such as viscosity lubricity flash point combustion quality. Therefore for ships using ULSD fuel it is necessary to equip a cooler system to overcome the disadvantage of ultra-low viscosity like ULSD. Due to this reason the combination of two fuel types such as ultra low- viscosity ULSD and high-viscosity Biodiesel BO fuel aiming to form a new fuel type which satisfies not only the required viscosity and renewable properties but also the requirement of reducing the cost of ship operation will have a great significance in terms of economy technology and emissions. .
