Marine Propulsion Services

The experts at Datum Rotating Machinery services work with builders and shipyards nationally and internationally for marine propulsion services.

Datum staff can provide service to remove and install propellers, shafting, install shaft bearings, and service or replace shaft seal systems.

Marine Laser Alignment

Datum Rotating Machinery Services (RMS) provides laser alignment services for shipbuilding as well as commissioned vessels. Marine laser alignment includes:
  • Engine drive shafts & support bearings, also placement
  • Main engines
  • Bore alignment
  • Propulsion & propeller shaft
  • Reduction gearboxes
  • Stern tubes, cutless bearings & struts
  • Z drive propulsion systems
  • Propulsion & propeller shaft alignment
  • And location of jet-drive assemblies
  • Benefits of Marine Laser Alignment Services

    • Main drive engines – Proper alignment of the drive shafts, best attained through Laser alignment, keeps engines running in optimal condition.
    • Reduction gears reduce an input speed to a slower output speed. Laser Alignment reduces the bearing reaction forces on the reduction gear. This improves efficiency and reduces downtime.
    • Propeller shafts – Laser Alignment of shafts provide 10 to 100 times the accuracy of conventional methods. Precision Shaft Alignment removes harsh forces that can cause premature bearing failure and reduce seal life.
    • Generators – Laser alignment can be used to align generators with main shafts to reduce vibration and markedly improve equipment reliability.





    Marine Optical Alignment

    Our Marine Alignment team will perform the job quickly and to the highest standard of accuracy for your yacht or commercial or military vessel. We use state-of-the-art equipment to check machinery. This precision alignment is of utmost importance. Contact us today to learn more about how our team will precisely align your machines.

    Marine Optical Alignment Services Include:

    • Propeller shaft-line – Allow us to help align your propeller shaft-line prior to installation as well as help with maintenance
    • Reduction Gears – Alignment or reduction gears can increase the life expectancy and efficiency of all components in the drive train.
    • Main Engines –  If your vessel is experiencing issues, our team may be able to isolate it through an optical alignment.
    • Rudder Bores – Rudder shaft bearings and upper carrier bearings must be properly aligned.



    Bore Align Laser System

    Precision alignment measurements of stern tubes and propulsion system bores.

    Strain Gauge Alignment Method

    Strain gauge alignment measurements on large marine shafting. These measurements can be used to extrapolate the bearing loads and shaft bending moments, corroborated by bearing jack-up measurements.

    Testimonials & Reviews

    I have hired Datum several times over the past 2 years to carry out a wide range of services for us. It’s important that our propulsion system is 100% reliable and having Datum carry out our annual propulsion service and vibration analysis gives us piece of mind.

    They do what they say at the stated price. I unequivocally endorse them & would readily use them again, should the need arise.

    Steven Ruben

    Yacht Owner
    I am very pleased with both their quality of work and work ethic. They are professional and great in all respects to work with. We have again contracted with Datum for a follow up alighment check. I highly recommend Datum and their service Engineers.
