CLIENT STATEMENT & FEEDBACK
"I would like to express my appreciation for the overhaul performed by your crew. They were not only very technically proficient but also very professional and personable. They quickly became valued members of the Engineering staff and the ship's crew.
The team leader took the time to train my 3rd Engineer in some of the more technical aspects of the overhaul process. The team informed us of the work progress every evening and morning.
Any special requirements that arise were presented beforehand so they would not interfere with our schedule. All unusual and noteworthy findings were promptly presented and discussed with us.
Once the overhaul and testing were completed to our satisfaction, the team not only cleaned up their tools but also the engine and the area around it (including wiping down the overhead; I was very impressed). Upon completion, we were presented with the final copy of the service report, which included all the inspections and the parts used in the inventory. That allowed us to update the ship's spares much more quickly.
Please forward my commendations to the team for a very well-done and much-appreciated job. It was a pleasure to work with such professionals. They (and their expertise) are welcome onboard any time."
