NV Dynamics was retained by M/s. Les Concierges Services Pvt Ltd to carry out vibration assessments on ground floor of the Inventor building located at ITPL, Whitefield. The primary objective of this study was to evaluate the ambient vibration levels in the ground floor lab space, where vibration sensitive equipment is planned to be installed. Vibration assessment was carried out in 4 locations inside the designated floor space. The acquired vibration data was processed and the result was drawn against vibration criteria curves.

M/s. Afcons infrastructure engaged NV Dynamics to assess vibration severity levels due to their ongoing metro construction along the 11.2 km metro corridor of Kochi metro’s phase 2, which features a newly elevated line named pink line, with 10 new stations starting from Palarivottam junction to Infopark. Vibration assessments were carried out during piling operation which involved different construction activities such as boring, auguring, bucketing etc. The collected vibration data was processed and the peak particle velocity values were compared with the applicable FTA guideline values.

NV Dynamics was engaged by M/s. Precot Limited to conduct vibration analysis on a motor/blower fan unit of 110kW. Vibration levels of the motor/blower fan unit was initially assessed under various operating conditions, followed by a comprehensive vibration analysis. The investigation indicated the problems with the front bearing assembly of the motor along with high intensity knocks and shock events in synchronization to the rotational movements of the motor indicating the bearing damage, to mitigate this issue recommendations were proposed to the client.

M/s Chowgule and Company Pvt. Ltd. engaged NV Dynamics to conduct comprehensive noise assessments for their newly constructed General Cargo Vessel, named “JILL C,” currently located at Mormugao Port, Goa. The scope of work included carrying out noise level measurements onboard, under both harbour conditions and during sea trials. These measurements were performed in a single designated habitability space to evaluate compliance with applicable maritime noise standards and regulations governing shipboard noise levels.
