Navy Picks DEXTER for LSD Class


Study shows high return, short payback
An independent Business Case Analysis, requested by the U.S. Navy, predicts a 13-to-1 return on investment (ROI) in maintenance cost savings with DEXTER for LSD class ships.

Navy Projects 13-to-1 ROI with DEXTER

Independent Business Case AnalysisAn independent Business Case Analysis for installing DEXTER on the Navy’s LSD class vessels predicted over a 13-to-1 return on investment (ROI) in maintenance cost savings. The study was conducted by ASC (Washington, DC) at the request of the LSD life cycle support office. Actual cost data from historical LSD maintenance activities was analyzed to determine DEXTER’s cost avoidance potential.

All ships in the LSD class are undergoing a mid-life modernization to replace obsolete systems with modern technology to cover their next fifteen years of service life. DEXTER is now an integrated component of the new machinery control system., operating on Windows-based MCS workstations located throughout the machinery spaces. DEXTER acquires real-time machinery data directly from the new control system’s network, allowing DEXTER’s diagnostic and prognostic software modules to perform real-time equipment fault analysis and prognostic reporting to the crew. In practice, operators will verify the reported faults and either stop equipment for repair, make adjustments, or change operating profiles to avoid failures or improve fuel efficiency. Since DEXTER is primarily software, its neural network-based diagnostic and prognostic capabilities can be readily integrated into most modern control systems.

The Navy study examined approximately ten thousand historical engine casualty data records and modeled this data through DEXTER’s diagnostic intelligence features to determine which casualties would have been avoided if DEXTER were installed.

This resulted in a projected maintenance cost avoidance of approximately $44.5 million over the next 15 years of remaining life of this ship class.
The projected ROI for DEXTER was estimated at $13 to $1., with a payback period of approximately 13 months.

In other Navy applications, DEXTER provides expert-level real-time machinery health monitoring, notifies crew of impending casualties, suggests maintenance and corrective actions to avoid casualties, and accurately documents historical machinery plant operating parameters, much like a “black-box” data recorder. Through standard interfaces, DEXTER fault information can also be fed into any computerized maintenance management system for automatic generation of maintenance work orders.

The study concluded that DEXTER offers a positive ROI, short payback, and advances the Navy’s Condition Based Maintenance (CBM) effort. Based on these findings, the Navy decided to install DEXTER on all twelve ships of the LSD 41/49 class as part of their Mid-Life modernization. All ships of the LSD class will undergo mid-life modernization over the next five years to ensure that they remain capable assets and can meet mission requirements through 2038.
