In this paper we shall compare the conventional and traditional methods for checking tail shaft alignment with Wärtsilä’s state-of-the-art Portable Condition Based Monitoring (PCBM) system. The positive effect that modern dynamic monitoring of a vessel’s equipment can have on overall operational efficiency will also be highlighted. Efficiency represents a critical element in lowering operating costs and, by extension therefore, in improving its profitability. Correct alignment of the tail shaft is an important contributing factor in achieving full efficiency.
