ON-SITE TECHNICAL SERVICES, INC. was founded in 2004. As President of ON-SITE, Mr. Kent Kreeger provides leadership and direction to our domestic and international inspection staff to meet our clients’ needs and expectations. His experience includes large-diameter valves, pumps and hydraulic turbine generators, forgings, and welded structures, pressure vessels, and mechanical assemblies. Mr. Kreeger is a Mechanical Engineer with over 25 year’s experience supporting Project management as a Reliability engineer for the Rotating Equipment. In this role his responsibilities include Quality Assurance for new and repaired equipment, Vibration Analysis and Failure Analysis.
Today, ON-SITE provides fabrication Quality Assurance services for our clients in over 15 different countries and our Construction Quality Assurance inspection team supports numerous high profile Public works projects throughout the United States. Mr. Kreeger leads our mechanical equipment team providing technical support to our clients including, installation and start-up support, vibration analysis, failure analysis, and problem resolution are some of the services that are provided to our clients.
Mechanical Equipment Support:
During the purchasing phase our team provides specification review, submittal review, completes audits of fabricators facilities. During fabrication in process inspections are completed including witnessing performance and functional tests. Once the equipment has been received we work closely with the construction team to insure the equipment is properly installed. During start the equipment is closely monitored and vibration analysis is completed to insure proper operation. Often our clients ask for support during the repair process of complex equipment. Our team of engineers will complete visits to the repair shop and witness critical measurements and processes. Initial visit include inspections that will help determine the failure mode of the equipment. During final assembly our engineers will witness the assembly confirming all of the components are dimensionally correct and it is correctly assembled.
Field services include inspection support during outages and pump replacement. Our engineers confirm alignment and pipe strain prior to start up. During start up vibration, temperature and other critical process items are closely monitored.
Field Vibration Analysis:
Often ON-SITE is called on to provide failure analysis inspection support. The ON-SITE team works closely with Metallurgical Labs and specialty Engineering firms identify the failure mode. Often Finite Element Analyses and other computer modeling is required coupled with the lab analysis and process data is required to fully understand the failure mode.
