Our Field Service Department consists of maintenance specialists who know all there is to know about heavy-duty GE-designed gas turbines (MS1002, MS3002, MS5001, MS5002, MS6001 and MS9001).
From the maintenance base in Rheden in the Netherlands, we send people to client sites all around the world at very short notice. In emergency situations, we can get complete crews with all the necessary skills rapidly to client sites – usually within 24 hours in western Europe.
Our field service engineers, who have all received extensive training, have experience of dealing with a wide variety of maintenance issues and troubleshooting tasks. In addition, senior engineers based in Rheden have many years of field experience and are constantly available to support engineers at client sites. They are also available via telephone, fax or e-mail to answer client questions.
Our working methods and procedures are in accordance with ISO 9001:2000. We also
offer fully engineered, lifetime-extension modifications, resulting in significantly extended periods between overhauls.
SITE INSTALLATION
As Thomassen International have built and installed more than 300 GE-type gas turbines, we have many highly experienced site managers, project managers and commissioning engineers, ready to carry out installations and upgrades around the globe.
MODIFICATIONS OF CONTROLS
Gas turbines running with Speedtronic Mark II, Mark IV, Mark V, or other versions can be upgraded with new digital control systems, such as the Speedtronic Mark VI Simplex or Thomassen TC7. We can design, procure and install upgrades at client sites.
EMERGENCY SERVICES
For clients with long-term maintenance contracts, we offer a 24-hour emergency hotline.
You will be able to contact an engineer who can give you immediate advice or locate the
appropriate specialist for a consultation.
If the THOMS online monitoring system is installed, we can provide on-line troubleshooting and thus resolve most problems remotely.
TOOL CONTAINER
For all maintenance tasks, we can provide clients with tool containers fully stocked with standard and specialized tooling to enable inspections at client sites. Containers are of the standard 20ft x 8ft x 8ft size for ease of transportation. All tooling within the container is surveyed to both Lloyds’ or Det Norske Veritas’ lifting and handling standards to ensure that client safety procedures can be followed. If required, the container itself can be surveyed to SWL specifications for sea transportation and lifting onboard oil or gas production platforms.
For planned maintenance periods, containers can be shipped to client sites at least one week prior to maintenance outages. For emergency support they are shipped within 24 hrs from our Rheden base.
BOROSCOPE INSPECTIONS
With our digital boroscope equipment, we can survey and record in situ most components located in the hot gas paths of the combustion and turbine areas. We can examine the variable inlet guide vanes and the first-stage rotor and stator vanes of the compressor, while viewing the internal condition of pipe work and specifically flexible units, in order to establish any internal corrosion or collapse. On completion of the survey, client personnel can immediately view the results and a decision can be made as to whether to open the machine. Our full report, which contains digital photographs, it is normally issued within a week of the inspection.
Since the boroscope technique is now based on a digital system, we can download the information directly to our home base at Rheden, where a specialist can view the photographic evidence and suggest what action should be taken, thus minimizing downtime.
