One of the current goals in naval architecture industry is to reduce vessels emission to reach the baseline set by the environmental legislation such as MARPOL Annex VI and MEPC regulations (i.e. MEPC.203(62)) listed by the International Maritime Organisation (IMO) and Marine Environment Protection Committee (MEPC). This legislation outlines the Energy Efficiency Design Index (EEDI) and Ship Energy Efficiency Management Plan (SEEMP) requirements. Most of the MEPC regulations are adopted by the MARPOL Annex VI to assist the implementation of EEDI and SEEMP. To summarize the legislation and regulation[1], it aims to reduce the cost of mitigation such as greenhouse gases up to 20%; reduce sulfur content in fuel to only 0.1% and to increase energy

Some of the implemented technology are to reduce vessel speed to less than 20 knots, modification of propulsion and powering engines, reduction of drag coefficient, voyage planning and instalment of renewable and clean alternative propulsion. Some of the solutions such as reducing the ship velocities and fuel consumption do post implementation reluctance from the stakeholder as the voyage duration are prolonged. Solutions are available to possibly reduce the global emission but the feasibility of implementation are questionable in the terms of efficiency and economical aspect of loss and profit margin[2]. Renewable energy such as wind, solar and tide could be the next breakthrough in the industry in order to meet the environmental and energy efficiency …show more content…
By reducing 30% of VLCC power consumption could result in 20% reduction in EEDI ratio according to [9] but this again would greatly affect the vessel velocity which is not the optimum solution. Solar powered vessel is not on the top list of the possible solution due to the low efficiency and high cost of solar panel The highest efficiency of solar panel reported in 2015 less than 50%. [12]. The limitation would be the space that needed for the allocation of solar panel would greatly reduce the space for loading especially container ship or LNG vessel that are mainly for carrying goods or
