Vol. 1, Iss. 1

515--522

One of key ways of assuring a high level of reliability of a ship power plant is to design redundancy of its structural elements, for example redundancy of prime drivers, drivelines etc. This paper deals with issues related to the redundancy as a way increasing dependability of the ship power and propulsion systems. Especially, fundamental characteristics of dependability, major design strategies influencing the reliability, and types of redundancies related to ship power and propulsion systems are presented.

Power and propulsion systems of offshore units must be of a very high level of reliability. The loss of ability to perform functions of their components causes generally to very high economic losses, which may be increased by unused the weather window resulting to postponing the planned offshore operations. To ensure carrying out so expensive offshore operations in the most reliable way, various types of redundancies are built-in ship power plants. This paper deals with issues related to application of redundancy in ship power plants of offshore vessels. Especially, evolution of redundancy application in ship power plants, and design solution of redundancy for offshore vessels are presented. Moreover, the specifics of these offshore operations so important from the point of view of minimizing financial losses due to any interruptions caused by failures of power and propulsion systems are discussed in detailed way.
