ESRG, LLC is the developer, proprietor, and commercial licensor of the IPAR and MELS software, which provides machinery condition assessment, diagnostic, prognostic and management decision support capabilities for US Navy HM&E and Combat Systems equipment.
MELS is a Web based server that stores and allows access to shipboard operational data and provides an Integrated Performance Analysis Report (IPAR). The data is collected by the Integrated Condition Assessment System (ICAS), which leverages the existing infrastructure of the ship’s machinery control systems for critical maintenance data. This native data, which is ship specific, is incorporated into a commercial off-the-shelf relational database. Once the data is in MELS, SMEs can view it by using standard Internet browsers, and the ICAS software is no longer needed.
The figure below is an example of an IPAR view.
This view represents an AC IPAR screen from a modern ARLEIGH BURKE class guided missile AEGIS destroyer. In addition to current fault status, this screen provides additional information when the user clicks on the yellow (warning) or red (alert) cells. Over time, as more machine data is gathered, SMEs can better understand failure rates and causes of the failures.
MELS also includes a newly developed Workflow Management Tool used to support the IPAR process. Recently, we have added automated 2Kilo request functionality to the MELS workflow (contact us for more information).
The benefits of the MELS system are an efficient maintenance process, reduced manning, and increased equipment and mission readiness.
Below is a chart that illustrates the ship types that currently use MELS ICAS/IPAR.
The XCraft is our newest MELS install and is used to monitor the main propulsion diesel engine. Click here for more information.
The chart below shows the types of systems MELS is monitoring and the number of ships covered.

RCM is a systematic approach to developing focused, effective, and cost-efficient preventive and predictive maintenance programs.
Condition-based Maintenance (CBM)
Condition assessment is a vital part of a condition-based maintenance program that will improve asset productivity while reducing maintenance and operations costs. CBM provides predictive, early warning of deteriorating conditions that will likely lead to failure or poor performance.
Condition-based Operations (CBO) Solutions
CBO leverages CBM information in conjunction with other operating environment inputs to make better-informed operating decisions for an effective enterprise.
