Environmentally Sound Limited diagnoses vibration-driven failures, fatigue cracking and persistent plant reliability problems, and engineers the corrective modifications that restore reliable operation.
Diagnose → Measure → Analyse → Design → Support
Vibration & Structural Dynamics (Reliability Engineering)
When machinery or plant systems repeatedly fail, operate below capacity, or never operate relaibly as intended, vibration is often the symptom of an unresolved dynamic mechanism such as resonance, dynamic amplification, structural flexibility, forcing or boundary-condition effects.
Environmentally Sound diagnoses the governing vibration mechanism and develops practical engineering modifications that restore reliable operation.
Reasons clients contact us:
Machinery failing due to vibration or unable to operate reliably in its vibration environment
Repeated cracking, broken brackets, failed welds, leaking joints or loosened fasteners
Operating restrictions due to vibration risk (speed/load derating or capacity limits)
New equipment or upgrades failing acceptance criteria or compliance targets
Piping and structural vibration with fatigue risk near tees, valves, supports or machines
Noise, Structure-Borne Sound & Vibroacoustics
Resolution of airborne and structure-borne noise generated by vibration and structural behaviour in machinery, plant and building systems.
Many noise problems originate from dynamic forces within rotating machinery, process equipment or structural systems that excite vibration and radiate sound through connected structures.
Environmentally Sound diagnoses the governing vibroacoustic mechanism by analysing the interaction between vibration excitation, structural response and acoustic radiation
Engineering analysis addresses the complete source → path → receiver chain using Transfer Path Analysis (TPA) to identify how vibration energy is transmitted through structures and radiated as sound.
Corrective engineering measures may include structural modification, stiffness changes, vibration isolation, damping treatments or alterations to load paths to remove the underlying mechanism.
Solutions are developed and verified using a structured engineering process:

Benefits to Our Clients
Diagnose — Understanding the Governing Mechanism
Persistent vibration problems often involve uncertainty, conflicting opinions and repeated unsuccessful repairs.
Engineering diagnosis identifies the governing mechanism responsible for vibration, fatigue or instability so corrective action can be targeted effectively.
Measure — Establishing the Real Behaviour of the System
Accurate measurement reveals how machinery, structures and connected systems are actually responding in operation, providing the physical evidence required to understand vibration behaviour.
Analyse — Interpreting Dynamic Behaviour
Engineering analysis links the measured response to the underlying dynamic mechanisms such as resonance, structural flexibility, forcing or machine–structure interaction.
Design — Engineering the Corrective Modification
Once the governing mechanism is understood, practical engineering changes can be developed to remove the underlying cause of vibration, fatigue or instability.
Support — Ensuring Successful Implementation
Where corrective modifications are required, Environmentally Sound can support implementation by working with client engineering teams, fabricators and contractors to ensure the solution is introduced correctly and performs reliably in operation.
Chartered Mechanical Engineers — Mechanical Engineering, Vibration & Structural Dynamics
Environmentally Sound Limited diagnoses vibration-driven failures and persistent plant reliability problems and engineers practical corrective modifications that restore reliable operation. Work combines mechanical engineering understanding with vibration measurement, structural dynamics analysis and engineering design.
