Laser Alignment of Main and Auxiliary Engines, Machinery and Shafts

Marine engineer performing laser alignment of ship machinery

AirSea provides precision laser alignment of main engines, auxiliary engines, gearboxes, shafts and rotating machinery. Accurate alignment helps reduce vibration, prevent excessive wear and lower the risk of unexpected breakdowns during vessel operation.

Our engineers perform alignment checks and adjustment works directly on board using professional laser measurement equipment. This service is especially important after machinery installation, overhaul, foundation work, bearing replacement or when vibration and abnormal wear are detected.

Where we work

AirSea performs precision laser alignment directly on board, at shipyards, in ports, at anchorage, and during scheduled maintenance stops worldwide.

Our mobile engineers arrive with portable alignment equipment and can work under limited space, time, and access conditions. We support vessels during drydock, emergency repairs, machinery replacement, overhaul, commissioning, and pre-departure checks.

We commonly provide laser alignment services for:

 

  • Main engines and auxiliary engines
  • Gearboxes and couplings
  • Shaft lines and intermediate shafts
  • Pumps, compressors, generators, and rotating machinery
  • Machinery foundations after repair or replacement

 

Whether the vessel is in port, at anchorage, or preparing for sea trials, we help restore correct alignment, reduce vibration, and prevent accelerated wear of connected equipment.

Information required for request

To prepare a fast and accurate response, please include the following information in your request:

 

  • Vessel name and IMO number
  • Current vessel location, port, anchorage, or shipyard
  • Preferred service date and urgency level
  • Equipment type requiring alignment
  • Brand, model, and serial number of the machinery, if available
  • Description of the problem: vibration, overheating, bearing wear, coupling damage, recent overhaul, replacement, or other symptoms
  • Scope of work required: inspection, alignment, report, corrective adjustment, or complete support
  • Technical drawings, shaft line layout, coupling data, photos, or previous measurement reports
  • Access conditions around the machinery
  • Contact details of the captain, superintendent, or technical manager

 

The more technical information is provided in advance, the faster we can estimate the scope, prepare the required tools, and dispatch the right engineer.

FAQ

When is laser alignment required?

Laser alignment is recommended after engine, gearbox, coupling, pump, compressor, or shaft repair or replacement. It is also required when the vessel has abnormal vibration, overheating bearings, coupling damage, repeated seal failures, or premature wear of rotating components.

Yes. AirSea performs laser alignment directly on board the vessel. Our engineers use portable equipment and can work in ports, shipyards, at anchorage, and in other operating conditions where safe access is available.

We align main engines, auxiliary engines, gearboxes, shaft lines, pumps, compressors, generators, and other rotating machinery. The final scope depends on the vessel layout, access, machinery condition, and technical requirements.

Yes. After inspection and alignment, we can provide measurement data and a service report describing the performed work, findings, and recommendations for further operation or repair.

The duration depends on the machinery type, access conditions, required corrections, and whether additional mechanical work is needed. Simple checks can often be completed quickly, while full alignment with corrective work may require more time.

Need precise alignment before departure?

Incorrect alignment can lead to vibration, bearing damage, coupling wear, seal failure, and unplanned downtime. AirSea provides professional laser alignment of marine engines, shafts, and rotating machinery worldwide.
