Definitions
- the present invention relates in general to a method of maintaining the operational capability of a technical installation and more specifically to a method of maintaining the operational capability of a turbine for electric power generation by furnishing substitute components for worn components .
- vanes and blades are used to direct a fuel flow, especially of a fuel gas, as desired.
- the vanes and blades, especially of gas and steam turbines with a high power rating, are exposed to extreme atmospheric conditions such as high temperature and/or other abrasive and stress causing influences and thus need regular inspection to determine a need for refurbishment or replacement of affected vanes and blades.
- the present invention provides a simple and effective method of maintaining the operational capability of a technical installation owned by a customer, the method being conducted by a maintenance provider.
- One aspect of the invention thus involves a concept of obligatory returning initially furnished new or refurbished components provided by a maintenance provider to the maintenance provider' s sphere after completion of each agreed maintenance cycle;
- the maintenance provider can for example be the Original Manufacturer of the components (OEM) : - furnishing at least one component of the industrial turbine under the condition that the furnished component is owned by the maintenance provider and will remain with the maintenance provider upon separation from the industrial turbine, and - removing the furnished component from the industrial turbine and providing the removed component to the maintenance provider after an agreed maintenance cycle.
- OEM Original Manufacturer of the components
- One maintenance cycle can thus be defined by furnishing new or refurbished components by the maintenance provider as a starting point and removing of the furnished new or refurbished components out of said customer' s sphere by the maintenance provider as an end point.
- This closed loop can be part of a lease agreement covering (only) the component (and not the entire turbine) or of an agreement on transferring property in initially furnished new respectively refurbished components to the maintenance provider after each agreed maintenance cycle:
- a further aspect of the present invention thus involves a computer system capable of automatic maintenance service managing, comprising:
- a database including at least one data record related to the industrial turbine wherein the data record includes technical information about the component, and a further data record including information on a maintenance agreement between the customer and a maintenance provider, the maintenance agreement including information about the number of agreed consecutive maintenance cycles and their respective duration, wherein the maintenance agreement further includes a clause that the furnished component is owned by the maintenance provider and will remain with the maintenance provider upon separation from the industrial turbine,
- - scheduling means for automatic notification of the maintenance provider of due inspection dates derived from the maintenance agreement and for automatic generation of at least one equipment list which includes information about the number of components scheduled for inspection, wherein a number of components to be manufactured by the maintenance provider in advance of a due inspection date and a number of components to be removed or received by the maintenance provider after any agreed maintenance cycle is derived from the number of components scheduled for inspection, and - input and output means for accessing the database and the scheduling means.
- An advantage of the invention includes a reduced inventory at the customer' s side because of the maintenance provider' s obligation to furnish all necessary components covered by the maintenance agreement during all agreed maintenance cycles.
- the customer has to deal only with one supply interface represented by the maintenance provider as the latter furnishes both refurbished (repaired) and new components .
- the customer thus benefits from an optimized investment over the lifetime of the technical installation, especially if he chooses the maintenance agreement to be continued over a number of consecutive maintenance cycles over the life-time of his industrial turbine. This is mainly because of all risks related to component failures are taken over by the maintenance provider throughout all agreed maintenance cycles .
- the maintenance provider benefits from a reliable and calculable service business. The risk of excessive and incalculable warranty obligations can be reduced by closing a number of maintenance agreements with a number of customers so that an average risk applies.
- Figure 1 is a flowchart of an exemplary process of the present invention showing an exemplary series of steps to maintain the operational capability of an industrial turbine owned by a customer;
- FIG. 2 is a flowchart of an exemplary alternative process of the present invention
- Figure 3 is a flowchart of an exemplary process of the present invention realizing at least two consecutive maintenance cycles
- Figure 4 is a flowchart of an exemplary alternative process of the present invention realizing at least two consecutive maintenance cycles;
- Figure 5 is a schematic diagram illustrating the invention in principle, including a number of consecutive maintenance cycles;
- Figure 6 is a schematic diagram of a computer system adapted to enable an embodiment of the invention.
- the disclosed invention advantageously employs one or more base concepts.
- One concept is the "closed loop” concept already described above which aims at keeping the furnished new or refurbished components within the sphere of either the customer or the manufacturer.
- Another concept involves granting the customer a warranty and/or charging the customer a flat rate including all necessary repair and replacement expenses related to the furnished components throughout each agreed maintenance cycle in order to enhance the customer' s confidence in the maintenance agreement.
- At least the first payable flat rate for the first agreed maintenance cycle can be considerably less compared to commonly known service & maintenance agreements, because the customer will not have to pay the full price for furnished components in which he will not be granted unrestricted property.
- Subsequent maintenance cycles - which preferably are charged at the same flat rate as the above mentioned first agreed maintenance cycle - can be as expensive or even a little bit more higher priced compared to common service & maintenance agreements, under which only defective components are exchanged for new or refurbished ones, as according to a preferred embodiment of the invention, all components covered under the maintenance agreement are substituted (not only defective ones) by furnished new or refurbished components at the beginning of each agreed maintenance cycle.
- This aspect of the invention thus provides the customer with a performance guaranty as compared to a simple component warranty.
- a further concept includes a number of consecutive maintenance cycles covered by the maintenance agreement so that both customer and maintenance provider benefit from calculable expenses respectively workload.
- Another concept includes a computer system which enables the maintenance provider to efficiently organize his service business by providing database and scheduling means preferably accessible over the internet.
- Figure 1 depicts a flowchart showing a series of exemplary steps that can be performed to efficiently maintain the operational capability of a technical installation owned by a customer .
- Step 1 provides furnishing at least one new or refurbished component by a maintenance provider wherein property in said component remains with the maintenance provider.
- Step 2 designates the end of the above mentioned maintenance cycle with said maintenance provider removing said new or refurbished components (furnished in step 1) out of customer's sphere.
- the customer may then decide to go with the same maintenance provider for another maintenance cycle or choose another maintenance provider.
- the concept described above can be regarded as a kind of lease agreement covering (only) the furnished components (not the entire industrial turbine) .
- Figure 2 reveals an alternative embodiment of the invention.
- Step 1 provides furnishing at least one new or refurbished component by a maintenance provider wherein property in said component remains with the maintenance provider.
- Step 2 includes agreeing on the property in said new respectively refurbished component to be transferred to maintenance provider at the end of an agreed maintenance cycle.
- Step 3 provides for removing said furnished new respectively refurbished component out of said customer' s sphere by the maintenance provider after said agreed maintenance cycle.
- Figure 3 further elaborates the embodiment already described in figure 1 by adding steps 3 and 4 (which are a likewise repetition of steps 1 and 2) to realize at least two consecutive maintenance.
- Figure 4 further elaborates the embodiment already described in figure 2 by adding steps 4, 5 and 6 (which actually a likewise repetition of steps 1, 2 and 3) to realize at least two consecutive maintenance cycles employing the invention.
- Figure 5 illustrates a schematic diagram including a number of consecutive maintenance cycles 10, 12 and 14.
- Each maintenance cycle begins with a major inspection of the industrial turbine, wherein a number of new or refurbished components 16, 18 and 20 are furnished to replace worn components; preferably all components exposed to wear are exchanged with furnished new or refurbished ones at the beginning of each maintenance cycle 10, 12 and 14.
- Figure 6 schematically illustrates a computer system 30 which enables the maintenance provider to efficiently organize his service business by providing a database 32 and scheduling means 42 preferably accessible over the internet.
- the database 32 includes at least one data record 34 related to said technical installation wherein said data record 34 includes technical information about said at least one component.
- the database furthermore includes a further data record 36 including information on a maintenance agreement between the customer and a maintenance provider, wherein the maintenance agreement includes information about the numbers of agreed consecutive maintenance cycles and their respective duration.
- the maintenance agreement further includes a clause committing the customer to return all components covered by and furnished under the maintenance agreement to the maintenance provider after each agreed maintenance cycle.
- the scheduling means 42 are adapted for automatic notification of the maintenance provider of due inspection dates derived from the maintenance agreement and for automatic generation of at least one equipment list 44 including information about the number of components scheduled for inspection, wherein a number of components to be manufactured by said maintenance provider in advance of the inspection and a number of components to be removed by said maintenance provider out of said customer' s sphere after each agreed maintenance cycle is derived from the number of components scheduled for inspection.
- the use of the invention is not restricted to maintaining the operational capability of industrial turbines; maintenance of any other technical installations with scheduled maintenance intervals and parts repair or exchange requirements may also benefit.
