Engineering Solutions

The same fundamental engineering challenges appear across different industries in different forms. We apply a common advanced-engineering core to structural integrity, dynamic systems, and measurement-based diagnosis—then adapt the solution to the operating context and decision needs of each sector.

Core Dynamics Solutions

Three core paths from technical uncertainty to an engineering decision.

Structural integrity and durability; dynamics, powertrain and NVH; and measurement-based diagnostics and correlation.

Reduce resonance risk, identify barred speed ranges and support class-compliant propulsion and driveline decisions. Dynamic assessment of marine shaftlines and automotive/defense drivelines: torsional, whirling, bending and axial vibration, resonance, barred-speed ranges, shaft alignment and critical operating regions — supported by measurement where required.

Extended Engineering Support

Focused support modules for test systems and system readiness.

These modules extend the core dynamics workflow with test-system engineering and RAM/FMEA/FMECA evidence where needed.

Test Systems Engineering

Design, integrate and validate subsystem test systems with dynamic behaviour understood before commissioning. We translate the test objective into a practical, instrumented test system—from operating loads and environmental conditions to drivetrain interfaces, rig construction, isolation and commissioning verification.

Existing test-system troubleshooting

For installed systems with recurring vibration, durability or operational-reliability problems, we combine measurement and analysis to identify the root cause. The findings are converted into an implementable design modification and a verification approach.

Systems engineering & verification basis

Using a proportionate V-model, we define system boundaries, interfaces, verification requirements and the minimum conditions needed for representative testing. Integrated FEA, MBD and measurement correlation then link requirements to rig design, commissioning evidence and acceptance decisions.

How We Can Help

Start with the problem. We connect it to the right engineering analysis and a decision-ready outcome.

Need a class-ready TVA report?

We build the mass-elastic model, assess natural frequencies, resonances, barred-speed ranges and torsional stresses, and deliver a traceable TVA report aligned with class-review requirements.

Unexpected vibration or noise?

We identify the source of unexpected vibration or noise and develop practical solution options.

Facing resonance or drivetrain dynamics problems?

We investigate critical speeds, torsional vibration, gear behaviour and powertrain dynamics problems.

Recurring cracks, deformation or premature failures?

We analyse the root causes of recurring cracks, deformation and premature component failures.

EEXI / CII Supporting Engineering

We perform focused calculations to quantify the structural and dynamic implications of defined efficiency measures, including propulsion-system changes, shaftline modifications and revised operating conditions.

Will your equipment pass an expensive qualification test?

Before costly physical testing, we assess whether the equipment is likely to meet shock, vibration and durability requirements.

Need engineering evidence for Lloyd's Register approval?

We prepare focused calculations, analyses and technical reports to support Lloyd's Register plan approval and technical review.

Concerned about reliability, maintenance or operational readiness?

Through FMECA and integrated RAM analyses, we assess failure risks, maintenance needs, availability and operational readiness.
