Fast Ferry Design for LNG Propulsion

摘要

The global trend in de-Carbonization of thernenergy system replicates the following path:rnCOAL>OIL>NATURAL GAS>HYDROGENrnThe drive towards environmentally friendlierrnfuels0 points next at Natural Gas (NG) and therninfrastructures to support that trend are beingrnpre-positioned by corporate mechanisms andrngovernmental bodies worlwide1. NG is will berncheap and plentiful.rnNatural Gas as fuel is well established in thernUrban Transport and Power Generation sectorsrnand that technology will transferrnsympathetically to the marine industry viarnavailability of engines, systems and technicalrnassistance.rnIts operational record is rated as GOOD and inrnthe US the cost of NG is competitive with ship'srnDiesel.rnA ferry operation requires fuel supplied in bulkrnrendering the distribution of Natural Gas viable.rnThe use of an alternative fuel for vesselrnpropulsion leads to a design review of powerrnplant, associated fuel system and propulsionrntrain; effectively reshaping areas such asrnMachinery Arrangement, Hull Form,rnCompartmentation, Car Deck, Payloads,rnSuperstructure, Interior Layouts, Escape &rnSafety, Route Options, etc.rnA rapid estuarial Ro-Ro commuter ferry designrnis herein proposed aiming at new opportunitiesrnand openings for estuarial ferry operations usingrnNatural Gas fuel.
