In the last decade a lot of emphasis was given to the propulsion redundancy of tankers. Since there are several levels of redundancy, it not always clear to what extent these redundancies can help in difficult situations and at last what is the objective of these redundancies. When we look at the costs optimization can be made minimizing the operating costs or it can be done in such a way that probability of spill and the size of its consequences are minimal. With this approach we are minimizing environmental risk. With environmental risk in mind only the higher level of redundancy is acceptable and lower levels are not enough to first prevent and second to mitigate the consequences of possible spills.
