Head of New Ship Construction & Conversion at CalMac Ferries

"As Technical Manager with CalMac Ferries Ltd we hired PZdynamics for the evaluation of turbo charger vibration behaviour following a refitting. On another vessel, PZdynamics also carried out vibration and structure borne noise measurements for the evaluation of the condition of gearbox bearings. Through a unique combination of measurement skills and dynamic mathematical modelling (design) skills, PZdynamics was found to be very effective in finding the ground causes and practical solutions for machinery dynamic, noise and vibration problems. 
  
I would also recommend them for their machinery condition evaluation and monitoring service. This service is a unique form of vibration based condition monitoring service relying again on a combination of measurement analysis skills and the design and mathematical modelling background. In my present role as Head of New Ship Construction and Conversion at CalMac Ferries Ltd, I have recognised that this service is particularly of great value for early identification of any drive line, structural and machinery design problems. This helps preventing unplanned downtime and speeds up the process of resolving any after sales issues with suppliers and shipyards."

Details of the Recommendation:

"As driveline engineer @AVD Holland I've been trained by mr Zoet. I've experienced a custom made course in torsional dynamic (driveline) behaviour. Meeting AVD's content requirements to the full extent. 
Pepijn's approach is enthousiastic, energetic and pragmatic which boosted my drive for continuing TV-analysis. The field of Pepijn's experience is were AVD has been operating succesfully, for the last 4 decades. 

In short, Pepijn added value to my daily professional 'drive' and AVD's near future!

Scott Ure, Technical Director

Calmac Ferries Ltd:

CalMac Ferries Ltd has engaged PZdynamics as consultants on a number of occasions for specialists consultancy and analysis on noise and vibration issues. Particularly for cases involving damage on drive line components such as gearboxes, bearings and couplings. They provide a broad range of services, from trouble shooting (noise and vibration measurements and analysis) and condition monitoring, to offering solutions for corrective action for drive lines and structures. Through a combination of specialist skills, PZdynamics are quick to identify the cause of problems, deliver practical solutions which save time and money and helps making the right maintenance decisions.

Some of the projects PZDynamics have worked with Calmac on are as follows :

• Turbo charger vibrations
• Engine vibration problems (plus redesign)
• Crankshaft failure problems (plus redesign)
• Coupling & shaft failure problems
• Gearbox bearing damage
• Research into the feasibility of LNG as a future fuel for LNG vessels (plus report writing)
