Laser Measurements

Laser measurement services
With state of the art laser equipment, precise measurements can be taken in various application areas:

  • Standard shaft alignment

       (engines, gearboxes, generators, pumps etc) 

  • Cardan shaft alignment

       (e.g azimuth propellers)

  • Straightness measurment

       (line bore of engines, stern tubes, rudderstock bearings etc)​

  • Flatness measurement

       (machine foundations, crane pedestals, thruster flanges etc)


Strain Gauge Measurements

By means of strain gauges, it is possible to measure shaft alignment while the shafts are coupled to the driving equipment. This technology offers numurous advantages in terms of time, accuracy and risk.
Strain gauge modelling/measuring is used in both new building and maintenance/repair. A model of the propeller installation is built in ShaftDesigner software.

More information can be found in the leaflet.


Engineering Services

We offer a package of Engineering services, comprising of:

Chocking plan and bolt tightening calculations
Comprises of all the needed calculations and drawings to chock and mount any machine in accordance with the rules of the applicable classification society.

Bolt calculations
For any application, bolt calculations are made for a long lasting and safe connection of machine or construction (parts). ExaktAlign provides advice for any mounting situation.

Selection of resilient mounts

To reduce the noise and vibration on board, engines and gears are set up on resilient mounts. Being able to choose from a wide pallet of mounts, the optimal solution is designed for your project.

Mounting Services

In combination with the mentioned products for Chocking and Mounting, we perform mounting of any kind of machinery. By means of state of the art calibrated hydraulic devices, we torque/stretch any bolt to their calculated value.


Complete engine performance measurements

​Independent evaluation of data with recommendation, like:

  • Measurements of dynamic parameters like pressures, stresses, temperatures, strain/stresses, flows (water & oil) etc

  • Crank angle based dynamic measurements of pressures (combustion, fuel, injection, rail, etc.) injector needle lift, strain/stress, voltages.

  • Noise; airborne and structure borne noise (ABN and SBN).

  • Torque / power measurement on rotating shafts via strain gauge sensor and telemetry transition.

 Vibration measurements

  • Lineair vibrations
  • Frequency analyses
  • Modal analyses
  • Dynamic balancing
  • Operational Deflection Shape (ODS)
  • Rotational Vibrations

3D Measurements

Geometrical Surveys (3D Measurements)
 In a Geometrical Survey, the shape or position of any object or space are measured and stored as XYZ coordinates for further use. Depending on the information needed and required accuracy, a Laser tracker, a Total Station or Laser Scanner is used. The number of applications is limitless. Typical applications are:
  • Dimension control
  • Reverse engineering
  • Quality control
  • Alignment in machines for paper, foil and steel
  • Hull / construction deformations
  • Robot calibration
  • Turbines
  • Etc
Laser Tracker
This measuring device measures with the highest accuracy (0.015 mm+0.006 mm/meter distance) of the above options with a distance of max. Ø320 m.
Total Station
 This is an optical measuring measuring instrument and is used for single point coordinate measurement purposes (no complicated shapes) upto longer ranges of max 800 m.
Laser scanning
Using state of the art 3D scanning equipment, the shape of any object or space can be measured and digitalized. These shapes are stored and reported in any CAD format for easy further use.

Water treatment Services
