Long Term Service Agreement

ANSALDO THOMASSEN TOTAL MAINTENANCE CONCEPT

Our Total Maintenance concept is the product of decades of experience in all aspects of GE-type heavy-duty gas turbine technology and our ISO-certified 9001:2000 management system. Our flexible service agreements are based on a total-maintenance concept, offering Customers enhanced unit availability and reliability, along with reduced maintenance and operations costs.

The concept includes the gas turbine, all auxiliaries and load gear, and generator, boiler and steam turbine maintenance in full-service Long Term Service Agreements (LTSA’s).

Our basic LTSA’s are modular in design in order to meet all of your needs. They include:

• Unscheduled maintenance
• Delivery of parts
• Component reconditioning
• Engineering support for gas turbines, controls and maintenance
• Scheduled maintenance
• 24-hour on-call service
• Unit operations assistance
• Customer training
• Up-grades

UNSCHEDULED MAINTENACE

Should a Customer be confronted with a forced outage, immediate contact is made with the contract manager. Our engineers gather all historical and real-time data on the unit via the Thomassen Online Monitoring System (THOMS). The liaison manager coordinates immediate dispatch of a service specialist who carries out extensive inspections. As soon as we determine the extent of the damage, we coordinate a detailed repair program with the Customer.

The liaison manager also handles planning, logistics, tooling and parts allocations.

PARTS DELIVERY

We can supply a complete range of new and refurbished capital, consumable and operational parts for MS3002, MS5001, MS5002, MS6001 and MS9001 turbines. Patented spare parts developed in-house as alternatives to OEM parts offer lower up-front and service-life costs, increased efficiency and lower emission levels.

By combining our strategic stocks, spare parts inventory at Customer sites and just-in-time deliveries of new parts, the liaison manager can minimize stocking of parts and maintain the highest levels of unit availability. We can arrange the transport of spare parts, including any necessary customs clearances, and provide full guarantees for both new and used parts.

COMPONENT RECONDITIONING

From our service centres worldwide, we offer refurbishment of all gas turbine components, including combustion components, hot gas path components, gas turbine rotors and all on-base and off-base equipment. During reconditioning, we can equip combustion parts with our Thomassen Extended Life Time Program (THOMELT) kits. All of our facilities are certified, controlled and supported by our main facility in the Netherlands. This enables us to guarantee short turnover periods, the highest quality and the lowest prices.

IN-HOUSE ENGINEERING

We use our comprehensive in-house knowledge of turbines, repair, controls and maintenance engineering to provide technical support for tailor-made technical solutions, including special fuels, performance improvements and reducing downtime.

SCHEDULED INSPECTIONS

The type of turbine and the installed components define the frequency of the inspections. The intervals between equipment changes vary according to operating conditions such as environmental conditions, firing temperatures, the number of starts / stops and running modes.

Appraisal visits to determine the general condition of the equipment precede scheduled inspections. This knowledge helps us anticipate requirements during scheduled inspections and enables more efficient planning for unit shutdown.

Each inspection finishes with a post-outage meeting, during which a detailed evaluation report is presented and discussed. Experienced Ansaldo Ansaldo Thomassen crews carry out scheduled inspections under supervision of one of our engineers. If Customers have their own mechanics available, they help with the inspections. Inspections can be executed in shifts to minimize downtime.

UNIT OPERATIONS ASSISTANCE

This option includes the services of a maintenance/ support engineer for the first year of commercial operation of your gas turbine generator. The engineer will adhere to a Customer-oriented contractual daily work schedule.
This assignment includes the presence of an engineer/ advisor at your plant, including an on-call service 24/7.
