ABSTRACT
Absolute commitment to reduce the impact of greenhouse gas emissions
while increasing fuel efficiency and power density requires further enhancement
of prime mover characteristics and special coatings, but mostly requires
compliance with EEDI (energy efficiency
design index) measures. For the
container shipping industry this represents significant increases in fuel costs
that can be mitigated above all by reduction of power demand, that is, of ship
frictional resistance. In this respect, this paper discusses advantages
attainable by application of the ACS (air cavity system) technology on the basis of recent KSRC (Krylov State Research
Centre) studies. Savings in
operating costs yielded by the enhanced propulsion performance for ships fitted
with this system are illustrated by a case study of a containership.
KEYWORDS
Air cavity, containership, fuel saving, energy efficiency, green ship.
