Gas Turbine Line Modification for Foundation Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas turbine arrangements are typically designed to be specific to a particular manufacturer's type, making it difficult and costly to replace one type with another without requiring a new foundation, which results in significant downtime and potential loss of operating licenses.
Innovation Solution
Modifying the blow-off and extraction lines of the gas turbine arrangement to prevent collisions with the existing foundation, allowing a gas turbine of a different type to be mounted without changing the foundation, including adjustments such as position shifts, cross-sectional reductions, and insulation changes, and using adapter plates to compensate for differences in anchor points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a gas turbine arrangement of a first type is installed on a foundation specifically designed for it, then the assembly is reliable and collision-free, but the foundation cannot accommodate gas turbine arrangements of different types from other manufacturers
Solution Approach 1:
The gas turbine arrangement is divided into modular components (casing, compressor, combustion chamber, gas turbine) that can be independently positioned and adjusted on the foundation, allowing different types to be accommodated on the same foundation through modular reconfiguration
Solution Approach 2:
The solution moves the adaptation from the foundation level to the component level by adjusting the spatial arrangement and positioning of individual gas turbine components in three-dimensional space, allowing type-specific arrangements on a universal foundation
2Adaptability or versatility
If the foundation is replaced to accommodate a new gas turbine arrangement from a different manufacturer, then the new arrangement can be installed, but significant downtime and high costs are incurred
Solution Approach 1:
The foundation is pre-configured with universal mounting structures and adjustment mechanisms that enable future installations of different gas turbine types without requiring foundation replacement, allowing seamless swaps during maintenance periods
Solution Approach 2:
An intermediary adaptation layer is introduced between the foundation and the gas turbine arrangement, consisting of adjustable mounting structures and positioning mechanisms that mediate between the fixed foundation and the variable turbine components
3Adaptability or versatility
If the foundation is replaced to accommodate a new gas turbine arrangement, then the new arrangement can be installed, but the operating permit may be lost requiring a new permitting process
Solution Approach 1:
The foundation is designed with universal characteristics that can support multiple gas turbine types while maintaining the same legal and operational identity, allowing the existing operating permit to remain valid across different manufacturer types through functional equivalence
4Adaptability or versatility
If blow-off and extraction lines are modified to prevent collision with the foundation, then a gas turbine arrangement of a first type can be mounted on a foundation designed for a second type, but the modifications add complexity to the system
Solution Approach 1:
The blow-off and extraction lines are designed with adjustable and movable sections that can be dynamically positioned to avoid collision with the foundation, using expandable joints and flexible routing that adapt to the specific spatial constraints of the installation

AI summary
The invention relates to a method for installing a gas turbine assembly (1) of a first type at a position of an existing power plant (12) where previously a gas turbine assembly of a second type was installed on a foundation (10) specially designed for said second type. The gas turbine assembly (1) comprises at least one housing (2), a compressor (3), a combustion chamber (4), a gas turbine (5), and a plurality of venting and removal lines (6, 7) guided along the exterior of the housing. The invention is characterized in that modifications to the venting and/or removal lines (6, 7) of the gas turbine assembly (1) of the first type are carried out in a first step, and the modified gas turbine assembly (1) is installed on the existing foundation (10) in a second step. The invention additionally relates to a gas turbine assembly.
