Vibration Analysis &Vibration Monitoring:

The effects of excessive vibration on the ship’s construction include equipment failure, breaking of the bulkheads and tanks, and miserable living and working conditions.
The approach for analyzing vibration readings regarding advisory limitations or for investigative reasons is narrowband frequency analysis.
The frequency of each individual component of interest over the pertinent frequency range should be able to be resolved using narrowband frequency analysis.

Vibration Analysis

Vibration survey machines are categorized as.

Class I Vibration Survey: Individual components of machines that are directly connected to the entire machine while it is in its normal functioning state. Typical examples of equipment in this category include production electric motors up to 15 kW.

Class II Vibration Survey: Medium-sized machines up to 300 kW on special foundations, rigidly mounted engines, or machines (usually electrical motors with 15 to 75 kW output).

Big prime movers and other large machines with rotating masses mounted on heavy, robust foundations that are somewhat stiff in the direction of vibration measurement are classified as Class III machinery.

Large prime movers and other large machines with rotating masses situated on relatively soft foundations in the direction of vibration measurement are classified as Class IV machines (for example turbo-generator sets, especially those with lightweight sub-structures)

Our Approach:

Measurement of vibration and vibration analysis for turbochargers, diesel alternative sets, rotating machines, and reciprocating machines, among other devices.

Analysis of Vibrations/Vibration Monitoring vibration levels for reciprocating compressors, main propulsion gear boxes, rolling element bearings, and pipework, among other equipment.

Vibration measurements for crew comfort.

Vibration measurements, monitoring, analysis, diagnosis, and troubleshooting for machinery.

Vibration Monitoring and measurement of vibrations in pipes and structures.

Vibrations caused by ship machinery/Vibration Assessment

industrial machinery Vibration monitoring and analysis, as well as vibration survey

Noise and vibration guidelines:

interpretation of ISO 6954:1984 Mechanical Vibration and Shock by Lloyd’s Register
Guidelines for evaluating vibration in merchant ships overall (1984).
Whole-body vibration analysis in accordance with ISO 6954
Machine vibration onboard, in accordance with industry norms
Provisional Regulations for Comfort of Passenger and Crew Accommodati
