Alignment inspection - passenger ship

November 2017 - This case was about inspection measurements regarding the straightness of the cutclass bearing pockets of propulsion system on a passenger ship. The propulsion system includes two engines with their gearboxes and shafts. Every shaft is supported by two V- brackets outside of the stern and one more cutlass bearing on the stern tube.

Our job was to verify the correct alignment of the two v-brackets, the stern tube and the gearbox on port propulsion system. For this purpose we used Easy Laser line bore E 950 system, a system that offers high accuracy for alignment measurements up to 40 m axis. The accuracy that can be reached with this equipment is up to 0.002 mm always depending on the environmental conditions (e.g. turbulence).
