Providing Scalable, Cost Saving Solutions to Improve Conditional Awareness of Your Enterprise Wide Assets.
November 06, 2008
ABSTRACT
The focus in maintenance and reliability has been on using proven individual diagnostic tools:
• Vibration Analysis
• Thermographic Inspection
• Ultrasonic Inspection
• Motor Circuit Analysis
• Oil Analysis
This evolution of predictive tools has often led to operating pressure, temperature and other indicators captured by equipment operators, data loggers or maintenance personnel to be overlooked. Open Standards such as OLE for Process Controls (OPC), the Machinery Information Management Open Systems Alliance (MIMOSA), and Open Operations and Maintenance (Open O&M), emerging technology and the internet allow us to now trend, analyze equipment data and PdM results to provide near real time enterprise asset analysis. The ability to quickly apply rule based analysis of process data enables continuous feedback to the diagnostic algorithms. Quick access to Key Performance Indicators (KPI’s) enables system experts to provide maintenance action recommendations, remote troubleshooting analysis and improved Enterprise Operational Equipment Effectiveness.
The US Navy surface fleet has implemented an enterprise solution for diagnostic decision support utilizing process and operational data and installed PdM technologies. Through the reverse distance support (RDS) initiative, more than 90 ships transmit data to shore and subsequently receive maintenance action reports from shore-based machinery subject matter experts providing enterprise diagnostic information. This has led to maximization of maintenance dollar expenditures, mitigation of ship visits by Tech Reps, and reduction in unplanned maintenance actions.
The US Navy has developed and implemented an effective performance analysis reporting system by:
• Identifying the critical assets to be monitored
• Performing Fundamental Engineering, Gap and Data Analysis
• Analyzing the existing IT Infrastructure and Host Option Selection
• Validating and Testing of Rules and Data Integration
• Integrating System Deployment
INTRODUCTION
The US Navy utilizes a machinery information data acquisition system known as the Integrated Condition Assessment System (ICAS). ICAS is a Commercial Off The Shelf (COTS) software product developed by IDAX Inc. for which the US Navy holds the Government Purchase License Rights (GPLR). The Navy is currently feeding the ICAS information into an Internet Web tool known as the Maintenance Engineering Library Server or (MELS). The backbone of MELS is a diagnostic engine that provides a common framework for applying user-defined prognostic and diagnostic algorithms to data in order to produce high-level “Quick Look” system health assessments.
This information drives a detailed view of system/equipment diagnostic analysis results known as the Integrated Performance Analysis Report (IPAR). The collection of the IPAR information is then consolidated into a view of system performance at the enterprise level. This Enterprise Performance Analysis Report or EPAR can then provide performance-driven analysis to support operation and maintenance decisions at the enterprise level. The analysis tool can easily progress from the enterprise level view down to the component level view. Expert analysis in the form of Reverse Distance Support (RDS) is the process where the Subject Matter Experts, (SMEs) receive automated reports of a specific ship system’s health to provide expert analysis and recommendations back to the sailor/maintainer if needed.
