Summary

This paper presents chosen activities of the ships propulsion system shafting alignment procedure. The main focus in this paper was put on sighting through (bore sighting) which can be done with three different types of measurement equipment: piano were, optical instruments and laser instruments. The analysis of measurement equipment allows selection of most optimal measurement solution for company. The matter of this selection is to avoid hazard to the shaft line due to shafts misalignment. Presented in paper measuring techniques and measurement equipment which is being used for sighting trough the elements of ships propulsion system meet technological requirements requested by the client and by the ship classification society
