Concept Development of a Sailing Cruise Ship Powered by Alternative Fuel

Abstract

I denne oppgaven har et konsept for et miljøvennlig ekspedisjonscruiseskip blitt utviklet. Skipet tar i bruk metanol som alternativt drivstoff for å være CO2-nøytralt. Seil blir også brukt for å kunne redusere utslippene enda mer. Beregninger har blitt utført for å bestemme skipets stabilitet, og permanent ballast har blitt brukt som en løsning for å møte kravene. Ettersom skipet er et passasjerskip, har sikkerhetskrav vært et viktig mål å følge. Dette har derfor påvirket utviklingen av blant annet generalarrangementet og tankplanet. Skrogutformingen har blitt designet for å være effektiv for den uforutsigbare operasjonsprofilen til skipet. I tillegg er skipet et luksus cruise skip og det har vært fokus på å lage et elegant og slankt skrog.

In this thesis, a concept for an environmentally friendly expedition cruise ship has been developed. The ship makes use of methanol as an alternative fuel to become CO2-neutral. Wing sails were also implemented to reduce the emissions even more. Calculations have been preformed to find out the ship's stability. Permanent ballast was used to meet the requirements. Since the vessel is a passenger ship, safety regulations have been considered important to follow. Therefore, the development of the general arrangement and tank plan were affected by this. The hull shape was designed to be efficient for the ship's unpredictable operational profile. In addition, it is a luxury cruise ship and the focus has been on making an elegant and sleek hull.
