Pro-Tec Geosystems Pte Ltd provides professional On-Board Vessel Machinery Vibration Analysis Services in Singapore for shipyards, vessel owners, ship managers, offshore operators and marine contractors. Our service helps assess vibration from rotating machinery, propulsion systems and vessel equipment to support reliability, crew comfort, troubleshooting, maintenance planning and marine project requirements.
On-board vessel machinery vibration analysis is a technical assessment used to measure and evaluate vibration from shipboard machinery, rotating equipment, propulsion systems and vessel structures. It helps identify abnormal vibration, assess vibration severity and recommend corrective action before vibration causes equipment failure, structural damage or crew comfort complaints.
Vibration may come from main engines, generators, pumps, compressors, bow thrusters, Z-drives, propulsion systems, fans, motors, gearboxes, shafting-related equipment and machinery foundations.
Excessive machinery vibration can affect equipment performance, bearing condition, alignment, foundations, structural components and accommodation comfort. A proper marine vibration analysis helps clients detect early signs of mechanical or structural issues.
Pro-Tec Geosystems carries out machinery vibration analysis services in Singapore with reference to recognised marine and vibration assessment criteria.
Where class requirements differ from general standards, the applicable project or class requirement may take precedence.
| Reference / Guideline | Purpose |
|---|---|
| ISO 6954:2000 | Vibration evaluation with regard to habitability on passenger and merchant ships |
| ABS Crew Habitability Guides | Habitability-related vibration assessment |
| Project-specific criteria | Client, owner, class or shipyard requirements |
| Manufacturer’s criteria | Equipment-specific vibration guidance, where available |
Pro-Tec Geosystems conducts ship machinery vibration monitoring at selected machinery and vessel locations.
| Equipment / Area | Survey Focus |
|---|---|
| Main Engine | Overall vibration and transmission path |
| Diesel Generator | Generator vibration monitoring and foundation review |
| Pumps / Compressors | Rotating equipment vibration |
| Bow Thruster | Bow thruster vibration assessment |
| Z-Drive | Z-drive vibration analysis |
| Engine Room | Engine room vibration survey |
| Propulsion System | Propulsion vibration survey |
| Accommodation Spaces | Vibration impact on crew comfort |
The survey may include vibration measurement, source identification, RMS assessment, frequency spectrum review, time waveform review and preparation of a professional machinery vibration analysis report.
Measurements are taken using suitable vibration instruments and accelerometers. Readings may be taken on machinery casings, foundations, floors, decks or crew contact points depending on the purpose of the survey.
Measurements may be taken during harbour trial, sea trial, 40%, 85%, full-speed transit or normal service condition.
| Possible Issue | Effect |
|---|---|
| Imbalance | Excessive rotating vibration |
| Misalignment | Bearing and coupling stress |
| Looseness | Unstable vibration |
| Resonance | Amplified vibration at certain speeds |
| Bearing Defects | Risk of equipment failure |
| Poor Mounting | Vibration transfer to structure |
| Foundation Weakness | Structural vibration spread |
| Coupling Problems | Abnormal mechanical stress |
Machinery vibration can affect both equipment and crew comfort. Sometimes machinery may operate normally, but vibration may travel through the vessel structure into cabins, offices, wheelhouse, mess rooms or recreation areas.
Pro-Tec Geosystems can support both machinery vibration analysis and vessel habitability vibration assessment.
| Test Point | Location | Operating Condition | Velocity RMS | Acceleration RMS | Remarks |
|---|---|---|---|---|---|
| PT-01 | Main Engine | Sea Trial | Measured value | Measured value | Review |
| PT-02 | Generator | Sea Trial | Measured value | Measured value | Review |
| PT-03 | Bow Thruster | Operating | Measured value | Measured value | Review |
| PT-04 | Z-Drive | Operating | Measured value | Measured value | Review |
The report may include vessel details, survey objective, reference criteria, machinery details, operating conditions, instrument details, measurement points, RMS values, peak values, spectrum data, observations, photographs, conclusion and recommendations.
Recommendations may include alignment checks, balancing, bearing inspection, foundation review, tightening loose components, coupling inspection, resilient mounting, vibration isolation, structural stiffening, propulsion maintenance or further diagnostic testing.
