Precision laser alignment

Precision laser alignment

Controlled shaft-alignment services for critical rotating equipment and complex machine trains.

Installation • outages • corrective maintenance

Talk to AMREA See the field workflow

The service outcome

Reliable alignment is a controlled process

The goal is repeatable, verified machine condition, not a one-off measurement.

A practical field workflow that establishes a stable machine foundation, corrects shaft position to the agreed target and leaves a defensible maintenance record.

Reliability

Reduce avoidable loads at bearings, seals, shafts and couplings.

Repeatability

Use controlled measurement, correction and re-verification.

Traceability

Record as-found, as-left and observations for future decisions.

Where the service applies

From straightforward coupled machines to critical, multi-element machine trains

Turbines and compressors

Train alignment, coupling interfaces and movement targets.

Pumps, fans and conveyors

Repeatable correction for process-critical rotating equipment.

Generators and motors

Driven/driver correction for installation, outage and maintenance scopes.

Complex trains (dredge, mills, kilns)

Coordinated alignment across multiple machines and couplings.

Typical work triggers

  • New installation
  • Commissioning
  • Shutdown / outage
  • Corrective maintenance
  • Reliability investigation

Field workflow

Inspect, correct, verify

Each phase is designed to make the final condition stable, explainable and retainable.

  1. 1

    Confirm scope

    Configuration, access, coupling, tolerances, foundation and agreed targets.

  2. 2

    Establish base condition

    Inspect and correct soft foot / machine-frame distortion before final alignment.

  3. 3

    Measure

    Capture repeatable vertical and horizontal alignment condition.

  4. 4

    Correct

    Shim and move the machine; apply approved thermal-growth or movement targets.

  5. 5

    Verify & report

    Tighten, re-measure, document results, actions, observations and recommendations.

Quality gate

Correct soft foot first

Final shaft alignment is meaningful only when the machine sits correctly on its base.

Why it matters

A poorly supported foot can distort the machine frame when hold-down bolts are tightened. Shaft position may change after an apparently successful alignment.

Controlled response

  • Inspect interfaces and foot condition
  • Clean and rectify contact surfaces as required
  • Shim using controlled correction
  • Re-tighten and confirm stability before final alignment

In practice

Complex train alignment in practice

Coordinate shaft position, coupling condition, machine movement and access constraints across the train.

Practical focus areas

  • Agree tolerances and machine movement assumptions before correction
  • Assess coupling, run-out, pipe strain and foundation condition as part of the alignment scope
  • Use approved thermal-growth / movement targets where operating conditions require them
  • Re-measure after each substantive adjustment and after bolt-up
  • Escalate related reliability findings rather than concealing them in a nominal alignment result

Deliverables

Evidence for maintenance decisions

The handover should be useful to planners, maintainers, reliability engineers and future outage teams.

As-found condition

Measured alignment state, constraints and observed issues.

Corrective actions

Soft-foot work, shimming, machine moves and relevant scope changes.

As-left verification

Final verified condition after tightening, with target assumptions identified.

Observations

Run-out, pipe strain, coupling, foundation and interface observations.

Recommendations

Practical follow-up actions, priorities and scope for additional investigation.

Mobilisation checklist

Prepare the job

Prepare the job so that alignment work proceeds safely, efficiently and without avoidable rework.

  • Scope and acceptance

    Confirm equipment configuration, couplings, target tolerances and acceptance criteria.

  • Work access

    Ensure isolations, guards, access, lighting, lifting and work-front client readiness.

  • Interface information

    Provide prior alignment records, vibration history and known baseplate or piping concerns.

  • Operating data

    Provide approved thermal-growth / movement targets and relevant operating conditions.

  • Machine readiness

    Confirm coupling condition, hold-down hardware, jacking / move capability and shim stock.

  • Close-out plan

    Nominate report recipients and the process for actioning observations and recommendations.

A practical basis for reliable rotating equipment

Plan the alignment scope around the operating reality of the machine.
