Techno–Economic and Risk Evaluation of Combined Cycle Propulsion Systems in Large Container Ships

Owing to the stringent regulations on pollutant emissions that are imposed by International Maritime Organization and increasing fuel prices, there has been significant research developing cleaner fuels novel propulsion systems. This study presents a techno-economical risk assessment method for evaluating alternative technologies as substitutes heavy oil two-stroke diesel engines in marine transportation. analysis was carried out two different journeys. Accordingly, we evaluated economic benefits of using an enhanced intercooler/reheat combined gas steam cycle or simple cycles were fueled liquified natural instead engine MDO system large container ship, considering shipping routes. The results highlighted advantages implementing simple, intercooler/reheat, A sensitivity performed investigate effects cost, capital hull fouling resistance analysis. For routes considered herein, compared MDO, LNG increased net present value 78.3%, 78.5%, 76.4%, respectively, reduced payback period 38.8%, 38.9%, 35%, respectively. Furthermore, costs had influence overall profit.
