CRP Azipod^® Propulsion Concept

-Advanced Cost-Effective Solution

抄録

This paper presents dimensioning and operational benefits of the CRP Azipod^®propulsion system. The system dimensioning is based on the data received from model tests conducted at the Samsung Ship Model Basin in South Korea. The CRP Azipod^® propulsion system demonstrated the best hydrodynamic efficiency as well as the best total propulsion efficiency, when the CRP Azipod^® was compared with a twin-screw twin-skeg system and a singlescrew system in model tests. As an example, dimensioning of the CRP Azipod^® system for the ULCS, Ultra Large Container Ship, is presented in detail and differences among these propulsion systems are considered. Finally, an operating cost comparison between the CRP Azipod^® and the twin-screw twin-skeg system for the 12000 TEU ULCSs is presented. It clearly reveals the CRP Azipod^® system is the most efficient propulsion system when operating costs are considered.
