AiP for LNG-fuelled PCTC designs
The AiP covers two pure car and truck carriers (PCTC) vessels with a respective capacity of 7,000 and 8,100 car equivalent units.
Both vessels are fitted with dual fuel systems that can use LNG and oil alternately and are equipped with IMO type C tanks which are independent self-supporting LNG fuel tanks. The IMO classifies LNG gas carrier fuel tank into two types: membrane tank and independent self-supporting tank. Independent tanks are further divided into Type A, Type B, and Type C tanks with Type C using a pressure containment system that ensures no risk of leakage. The ship design uses the optimum deployment of the fuel tanks to facilitate the loading of vehicles for shipping.
HHI believes that an LNG dual fuel propulsion system offers the most efficient solution to meet environmental regulations. An LNG dual fuel propulsion system can reduce CO2 emissions by 40-50% compared to 2008 levels, for all ship types including small and medium size vessels.
By applying additional energy saving devices such as air lubrication system and maximising the ship performance, an additional 10-20% reduction can be achieved, thereby meeting the environmental regulations by 2050.
