Abstract: To meet the increasingly stringent requirements of CO_X emission control, the key technologies of the methanol fuel as a propulsion power are studied based on a 210 000 tonnage conventional fuel bulk carrier, including the arrangement of the methanol fuel tanks, the design of the filling and supply system for the methanol fuels, and the safety and firefighting requirements for the methanol fuel application. Thus, a type of 210 000 tonnage methanol dual-fuel bulk carrier is developed. This vessel meets the requirements of MSC. 1/Circ. 1621 guidelines and IGF Code of International Maritime Organization (IMO). It adopts a full-width aft deck, and two methanol fuel tanks arranged on both sides of the engine casing at the ship stern, without affecting the cargo handling, nor reducing cargo capacity. Under the methanol fuel model, the emissions of particulate matter and sulfur oxide are eliminated, the nitrogen oxide emissions meet the IMO Tier III standard, and the ship energy efficiency design index (EEDI) meets the requirements of the third phase.
