Precision Services3D MARINE ALIGNMENT

ROTATEK provides 3D marine alignment services and precision measurement solutions including main engine alignment, reduction gear alignment, stern tube alignment, strut alignment and more. Utilizing the latest 2D and 3D laser technologies available, we are able to perform these services faster with higher accuracy than traditional methods saving valuable outage time and resources.

Excessive vibration on marine vessels can often be the result of misalignment which can ultimately lead to failures and costly repairs. For the safe and reliable operation of your propulsion system, precision alignment is an essential requirement.

A detailed graphical measurement report is supplied with all marine alignment services.

Our commitment to excellence paired with our state-of-the-art measurement capabilities makes ROTATEK your trusted precision service partner.

3D Laser Alignment and Measurement Solutions for Marine Applications

Unlike traditional alignment methods using piano wire, alignment telescopes and 2d laser optics, ROTATEK field engineers utilize 3D portable coordinate measuring machines (PCMM) including Laser Trackers and Articulating Arms for unparalleled accuracy, precision and measurement acquisition time.

Marine laser alignment services and precision measurement solutions include main engine alignment, gear alignment, bearing alignment, stern tube alignment, strut alignment, deck targeting, shaft alignment, dimensional analysis, part inspections, reverse engineering, geometric dimensioning, tolerancing, levelness, flatness, straightness, concentricity, parallelism, circularity, cylindricity, and more.

Main Engine Alignment

Main engine coupling alignment is quickly and accurately measured utilizing NIST Traceable Rotalign Laser Alignment Systems.

Reduction Gear Alignment

Reduction gear alignment is quickly and accurately measured utilizing NIST Traceable Rotalign Laser Alignment Systems and FARO Vantage Laser Tracker Systems.

Shafting and Bearing Alignment

Accurate laser tracker measurements can quickly verify shafting and bearing dimensions, stern tube bearing alignment, strut bearing alignment, pillow block bearing alignment and more

3-D Measurements

Laser trackers operate by measuring two angles and a distance. The tracker sends a laser beam to a retroreflective target held against the object being measured. As light is reflected off the target, it bounced back and re-enters the tracker at the same position it left and is measured by a distance meter, measuring the distance between the tracker and target.

Distance Measurement

The tracker sends a laser beam to a retroreflective target held against the object to be measured. The reflectedbeam returns to the tracker and its precise distance is recorded.

3D Measurement

Two angle encoders measure the elevation and rotational angles while a highly accurate absolute distance meter is used to determine the 3D position of the target. This position is shown in the software as an X, Y, Z value.

Tracking

The target returns the reflected laser beam parallel
but offset back to the tracker where it hits the position detector, which calculates the offset between the outgoing and incoming beam. Servo motors continuously (thousands of times per second) steer the tracker’s head to minimize the offset between the two beams, resulting in high-speed, dynamic measurements.
