Sažetak
To reduce pollution, LNG is increasingly used as a fuel in the maritime industry. This paper provides a methodology for the concept phase design of the LNG tank and fuel supply system on a ship. First, constraints of the ship, fuel tank and supply are determined. Next, the simultaneous design and optimisation of the fuel tank and supply system under defined constraints and realistic operating profiles is done. Tank design includes tank type, dimensions, insulation and design pressure analysis and structural strength assessment. Fuel supply system analysis is conducted using the developed dynamic model for comparing system configurations and equipment sizing. The methodology is demonstrated on two dual-fuel cruise ships of different sizes. The influence of ship operating conditions on the tank and fuel supply system and their interdependence is examined. Several candidates for the optimal tank design and fuel supply system are determined based on conflicting design objectives.
