Precision alignment of propulsion shafts, rudders, engines, and gearboxes to minimize vibration, improve fuel efficiency, and ensure smooth operation at sea.
Finite Element Modeling (FEM) Support
We provide metrology-driven FEM inputs and structural validation to support stress analysis, load simulations, and optimization of marine components, frames, and assemblies.
Laser Alignment of Rotating Machinery
High-accuracy laser alignment of onboard generators, pumps, compressors, and auxiliary systems to extend equipment life and prevent premature wear.
NIST-traceable contact and non-contact laser tracker services for verifying hull geometry, structural alignment, and large-scale components with sub-millimeter precision—ideal for ship construction, retrofits, and QA inspections.
Flatness and Straightness Verification
Critical measurement of bulkheads, deck plates, baseplates, and machinery foundations to ensure proper fitment and alignment across ship systems.
Laser-based alignment of propulsion and mechanical drive systems to reduce bearing load, energy loss, and operational stress in marine environments.
Specialized alignment of Cardan (universal joint) shaft systems, ensuring angular and parallel alignment across long-span or misaligned drive applications—ideal for marine propulsion and auxiliary systems with offset geometry.
Shaft alignment verification using strain gauges and FEM modeling for accurate analysis of stress and deflection during vessel assembly or retrofitting.
Predictive alignment services that account for thermal expansion and movement in propulsion and power generation systems, ensuring alignment remains in spec under operating temperatures.
Advanced vibration diagnostics for propulsion systems, rotating equipment, and structural elements to detect imbalance, misalignment, and resonance conditions before they lead to failure.
On-site balancing of rotors, shafts, and impellers to eliminate unbalance-induced vibration, reduce bearing loads, and restore smooth, efficient operation without the need for disassembly.
Dimensional Inspections & CAD Validation
Inspection of complex marine components and assemblies against CAD models or engineering tolerances, supporting QA/QC and classification society requirements.
Accurate 3D scanning and digital reconstruction of legacy or worn components to aid in part replacement, design updates, or performance upgrades.
Compliance Documentation & Reporting
Detailed, traceable reporting packages for alignment and inspection work to support quality assurance and regulatory compliance for shipyards and marine operations.
Emergency & Mobilized Field Support
Rapid-response alignment and measurement services for vessel outages, unexpected failures, or urgent dry-dock timelines—available worldwide.
