By adapting energy models from the utility industry, NAVSEA can create scalable energy models and meet CBM and RBM objectives. Maplewells Energy Management Control System (EMCS) monitors energy consumption and production, and energy models capture mechanical, electrical, material, and chemical problems and diagnose the condition of an asset or system. The EMCS harnesses energy models to monitor performance degradation and empowers decision makers to apply the correct maintenance strategies; decreased energy performance correlates with decreased reliability, resiliency, and efficiency. The EMCS solution also provides secure data transfer and a flexible communication interface with the Navy ERM; the EMCS acts as a supervisory control that pushes data to an edge controller for dynamic data processing and predictive control and then to the Cloud. Maplewells EMCS solution improves reliability at the asset level, builds resiliency at the system level, and ultimately improves fleet efficiency at the ship level. The EMCS architecture moves beyond reliability functions set by design standards, OEM recommendations, and standard maintenance methods; it integrates each assets distinctive energy model and reliability function signature and defines their impact on performance and reliability. With an EMCS, energy models can quantify the degradation by creating a digital twin of an asset, system, or ship that operating equipment uses as a reference for improvement; the EMCS also characterizes the reliability function and determines the effect of maintenance on reliability. Our model-based approach builds resiliency by enabling benchmarking to compare and identify relative performance and risk at the system level. Comparing relative performance between energy models of the same assets, systems, and ships identifies needs for maintenance or upgrades and enables shipyards to shift from reactive maintenance to predictive work packages. The EMCS also builds resiliency by defining and tracking the reliability function to quantify the risk of system failure, manage risk with maintenance, and improve upon standard practices. Changes in a ships mission and function also affect efficiency and cause a ship to operate outside of its intended design. By monitoring the ships systems (i.e., the power cycle), the EMCS can identify degradations in performance and capture longer-term trends for analysis to improve fleet efficiency and suggest new design standards. For the Phase 1 Option, Maplewell proposes a game theory approach to optimize maintenance for CBM and RBM. With well-defined energy models, simulations can improve maintenance programs, predict outcomes, and forecast opportunistic maintenance to the shipyard; game theory can find the optimal solution of cost, reliability, and performance for maintenance scheduling. Ultimately, Maplewells EMCS solution will create a well-defined CBM and RBM program with an optimized balance of cost and reliability.
Benefit: Maplewells EMCS solution adapts energy models from the utility industry and addresses pain points in the Navys current CBM and RBM programs by improving energy reliability, resiliency, and efficiency while maintaining operational readiness of the fleet. But this approach is not a pure, theoretical construct. Maplewells EMCS solution is taking a practical, real-world application in the utility industry and innovatively adapting it to solve a Navy problem around CBM and RBM. Energy models are an innovative approach that can move the Navy further away from traditional approaches and closer towards predictive and prescriptive models. By monitoring energy consumption and production, the EMCS works in a bottom-up approach to identify performance degradation in assets, systems, and ships and can be scaled up enhance the operational readiness of the entire Navy fleet. Maplewells EMCS solution will address vulnerabilities in the energy reliability of critical assets and systems that threaten to disrupt operational readiness of the Navys fleet. Energy models are precision weapons in the reliability arsenal that can pinpoint common maintenance problems of assets and enhance operational readiness, yet often go unutilized. Maplewells EMCS hardware and software architecture can enhance the energy resilience of assets, systems, and ships across the entire fleet, increase the capacity for optimization through data collection, analytics, and machine learning, and create secure, bidirectional data communication with the cloud to identify long-term trends in data. An EMCS solution centralizes performance monitoring and condition monitoring, and shipyards gain the capacity to optimize maintenance schedules and enable the ability to measure all energy consumption for critical assets. The EMCS also allows key stakeholders to make smarter energy efficiency choices such as evaluating load peaking, balancing energy loads, and quick decisions for more energy efficient ship operations. The EMCS and energy modelling has numerous applications for the Navy and other DoD branches. Maplewells EMCS solution provides a clear, viable roadmap from Phase I to Phases II and III and beyond into acquisition and fleet operation. Maplewells solution has direct application to any Navy asset or system in any ship that can be evaluated with energy models; when multiplied across the fleet, the EMCS solution has the potential to both optimize maintenance strategies and improve energy reliability, resiliency, and efficiency. Furthermore, the EMCS and energy modelling approach can be adapted to address the energy goals of military or government assets, systems, and facilities around the world.
