ENGINEERING
Engineering & Design Services
We offer advanced numerical analysis, finite element modeling, and customized acoustic design services during both the design phase of new builds and the retrofit stages of existing vessels:
-
Insulation Strategy & Custom Detail Drawings: Development of comprehensive insulation strategies and bespoke technical drawings specifying products that simultaneously meet strict acoustic performance targets and marine fire safety standards (IMO / Class approval).
-
Cabin Airborne Noise & Sound Level Calculations: Detailed sound pressure level (dB(A)) calculations for individual cabins and accommodation spaces to ensure compliance with classification society comfort class notations and project specifications. Optimized material selection is applied to achieve reduced noise levels without adding unnecessary weight or cost.
-
Partition Airborne Sound Insulation (Rw Value) Calculations: Calculation and optimization of sound reduction indices (Rw) for bulkheads, decks, and partition walls to ensure adequate sound privacy and transmission loss between adjacent spaces.
-
Structural Finite Element Analysis (FEA) & Resonance Mitigation: Finite Element Analysis (FEA) modeling to assess structural natural frequencies, identify potential structural resonance zones, and verify the structural integrity of machinery foundations under dynamic loading.
-
Propulsion System Dynamic Analysis & Mounting Specification: Technical evaluation of propulsion dynamics to select and size optimal elastic mounting components, flexible couplings, and thrust alignment elements for main engines and gearboxes.
-
Generator Elastic Mount Optimization: Frequency-matched selection and calculation of anti-vibration mounts for primary and auxiliary generators to minimize structure-borne excitation to the hull.
-
Custom Acoustic Enclosure (Sound Shield) Design: Custom engineering and design of high-performance sound shields for generators and high-noise equipment, balancing acoustic attenuation, ventilation airflow, and maintenance access.
-
Auxiliary Equipment Vibration Isolation: Precise calculation and selection of elastic supports and isolators for auxiliary machinery, including pumps, chillers, hydraulic power units, and compressors.
-
HVAC Acoustic & Fire Review & Yacht Plenum Box Design: Comprehensive technical review of HVAC distribution systems for acoustic attenuation and fire dampers. Custom engineering and design of yacht sound attenuation plenum boxes (platinum boxes) to reduce air-velocity noise and duct transmission.
CONSULTANCY
Engineering Consultancy Services
We provide expert technical guidance, project-tailored material selection, and strategic advisory services to help you make informed decisions and achieve high quality standards across both new build and existing vessel projects:
-
New Build & Project Consultancy:
Early-Stage Material & System Selection: Technical guidance on selecting the right class-approved (type-approved) materials and systems aligned with your project's fire safety, sound insulation, and thermal efficiency targets.
Insulation & Structural Concept Planning: Conceptual planning of insulation layer configurations and application methodologies tailored to achieve target comfort levels in accommodation spaces and engine rooms.
Equipment & Flexible Mount Selection Advisory: Guidance on selecting the appropriate flexible mounts, couplings, and expansion joints for main engines, generators, and auxiliary machinery based on manufacturer data and project specifications.
Shipyard Application Supervision: Monitoring and consulting on shipyard installation processes to ensure selected products and insulation details are applied using correct technical methods.
-
Consultancy & Improvements for Existing Vessels:
On-Board Inspection & Condition Assessment: On-site technical evaluations on yachts to investigate comfort degradation, excess noise, or vibration issues and assess existing installations.
Root Cause Evaluation & Mitigation Advisory: Identifying degraded vibration mounts, stiffened flexible connections, or compromised acoustic barriers, followed by recommending targeted corrective actions.
Retrofit & Refit Advisory: Practical, cost-effective solutions for integrating supplementary acoustic insulation, updating vibration mounts, or carrying out structural improvements without altering the vessel's primary structure.
Post-Application Verification: Final evaluation and verification following modifications to confirm that comfort targets and operational requirements have been successfully met.
TROUBLE SHOOTING
Vibration & Noise Troubleshooting Services
Comprehensive vibration and airborne noise assessments across all onboard machinery, accommodation areas, and deck spaces using certified and calibrated measurement instruments.
-
Acoustic & Vibration Source Tracking: Precision mapping to trace structure-borne vibration and airborne noise back to their exact origin, distinguishing between machinery excitation and secondary structural transmission.
-
Comfort Evaluation: Measurement of sound pressure and vibration levels in guest cabins, crew quarters, mess rooms, and the wheelhouse to isolate specific mechanical sources disrupting comfort and operational focus.
-
Main Machinery & Auxiliary Diagnostics: Advanced frequency spectrum analysis on main engines, generators, pumps, compressors, ventilation fans, and purifiers to pinpoint mechanical wear, resonance, or flow-induced acoustic noise.
-
HVAC & Ductwork Noise Troubleshooting: Spectral analysis of airflow and fan-induced noise through HVAC ducting, engine room ventilation systems, and exhaust piping to identify acoustic turbulence and structural rattle.
-
Shaftline & Propulsion Dynamics: In-depth analysis of propulsion signatures to detect operational anomalies, hydrodynamic pressure pulses, propeller-induced hull excitation, and shaft-line dynamic issues.
-
Structural Resonance & Critical Speed Mapping: Experimental resonance testing (bump testing) on machinery frames, bulkheads, decks, and piping to identify critical RPM zones where operating frequencies amplify noise and vibration.
-
Sea Trial Mapping: Complete operational mapping of noise and vibration across the full range of vessel speeds, sea conditions, and draft levels using multi-channel certified portable data collectors.
-
Root Cause Analysis (RCA): Systematic technical investigation combining spectral data, acoustic measurements, and physical analysis to uncover the exact root causes of chronic or complex noise and vibration problems.
-
Actionable Mitigation Solutions: Practical reporting featuring data-backed corrective measures—such as isolator upgrades, structural stiffening, acoustic damping, or pipe decoupling—to permanently eliminate unwanted vibration and noise.
