Method of managing operational health of assets
First Claim
1. An asset operational health monitoring system, comprising:
- a plurality of sensors arranged to determine values of asset operation parameters pertaining to an instance of asset operation; and
one or more processing units arranged to receive data corresponding to said asset operation values and to determine a plurality of asset locations at a corresponding plurality of points in time;
wherein the one or more processing unit is arranged to receive data indicative of the location of a region of adverse environmental conditions which may impact on the operation of the asset and to compare the determined locations of the asset with the location of said region so as to determine whether one or more of said asset locations fall within said region,wherein the one or more processing units outputs an indicator of maintenance risk associated with the presence of said asset in said region, the indicator of maintenance risk comprising (1) a count of the number of instances of exposure of the asset to one or more of said regions of adverse environmental conditions or (2) a value of duration or level of exposure of the asset to said one or more regions of adverse environmental conditions, andwherein the asset is a gas turbine engine.

Abstract
An asset operational health monitoring system, in which a plurality of sensors are arranged to determine values of asset operation parameters pertaining to an instance of asset operation. One or more processing unit receives data corresponding to said asset operation values and determine a plurality of asset locations at a corresponding plurality of points in time. The one or more processing unit is arranged to receive data indicative of the location of a region of adverse environmental conditions which may impact on the operation of the asset and to compare the determined locations of the asset with the location of said region so as to determine whether one or more of said asset locations fall within said region. An indicator of operational risk associated with the presence of said asset in said region is output which can drive asset operation or maintenance decision making. The system may be used for ash cloud impact monitoring for aircraft, a fleet of aircraft or aircraft engines.

13. A tool for monitoring a plurality of operational assets, the tool being arranged to receive asset operation parameter data and to determine a plurality of asset locations at a corresponding plurality of points in time for an instance of asset operation;
- the tool being further arranged to receive data indicative of the location of a region of adverse environmental conditions for the asset and to compare the determined locations of the asset with the location of said region so as to determine whether one or more of said asset locations fall within said region, wherein the tool outputs an indicator of maintenance risk associated with the presence of said asset in said region, the indicator of maintenance risk comprising (1) a count of the number of instances of exposure of the asset to one or more of said regions of adverse environmental conditions or (2) a value of duration or level of exposure of the asset to said one or more regions of adverse environmental conditions, and wherein the asset is a gas turbine engine.

14. A method of monitoring the operational health of an asset, the method comprising:
-
receiving data comprising asset operation parameter values; determining a plurality of asset locations at a corresponding plurality of points in time; receiving data indicative of a location of a region of adverse environmental conditions which may impact on the operation of the asset; comparing the determined asset locations with the location of said region at said plurality of points in time so as to determine whether one or more of said asset locations fall within said region; and
,outputting an indicator of maintenance risk associated with the presence of said asset in said region, wherein the indicator of maintenance risk comprises (1) a count of the number of instances of exposure of the asset to one or more of said regions of adverse environmental conditions or (2) a value of duration or level of exposure of the asset to said one or more regions of adverse environmental conditions, and wherein the asset is a pas turbine engine. - View Dependent Claims (15, 16, 17, 18, 19)
