Design of hybrid diesel-electric energy storage systems to maximize overall ship propulsive efficiency

Abstract
The concept of hybrid cars, where a combination of prime mover and energy storage allows a more efficient use of fuel shows considerable promise. Our work considers the same concept for ship propulsion using a storage medium in order to reduce the transient loads of the main engine (e.g. operation in rough sea, manoeuvre or speed variations) and applying a load levelling technique. Emissions that are produced in transient cases are higher and the developed reduction techniques deal mainly with the optimum operational point. This work, using real operational data of Post Panamax vessels, correlates daily sea state and engine loading to propose and size alternative hybrid propulsion system to reduce emissions and fuel consumption. The latter are calculated using the “as measured” fuel consumption; the bunker characteristics and widely adopted empirical formulae. Finally, the design issues of how hybrid technology would potentially affect modern ship design, are examined along with the economic feasibility of the proposed scenarios
