Ship Energy Use Monitoring and Analysis
Navy SBIR 2013.2 - Topic N132-112 NAVSEA - Mr. Dean Putnam - dean.r.putnam@navy.mil Opens: May 24, 2013 - Closes: June 26, 2013 N132-112 TITLE: Ship Energy Use Monitoring and Analysis TECHNOLOGY AREAS: Ground/Sea Vehicles ACQUISITION PROGRAM: This topic supports the Power & Energy Future Naval Capability (FNC). OBJECTIVE: The objective is innovative shipboard energy use monitoring and analysis to quantify energy use by all ship systems and equipment. DESCRIPTION: This topic proposes development of an energy monitoring and analysis tool meta-model to support all Navy stakeholders in understanding ship energy use. This meta-model will describe the analysis, construction and development of the frames, rules, constraints, models and theories applicable and useful for modeling Navy energy usage. This innovation will be used to develop a Shipboard Energy Use and Analysis system consisting of a shipboard component to capture energy use data interfacing with a shore-side analysis system. The Secretary of the Navy has set a goal to provide half of the Navy’s total energy consumption with alternative sources by 2020. The CNO policy pamphlet of October 2010, "A Navy Energy Vision for the 21st Century" identified a goal of reducing ship fuel consumption 15% by 2020 (Ref 2). Fundamental to achieving these goals is the understanding of how ships use energy. Currently no system exists to pull large quantities of data from classified sources, process this data into unclassified energy usage reports and metrics, and provide this data to multiple shipboard and shore-based stakeholders. This innovative software solution would be critical to helping the Navy understand, manage and track Maritime energy usage. This product will provide the data and analysis tools to enable ship acquisition managers to make more accurate assessments of product improvements and technology insertions. Knowing the energy demand of existing ship systems, the acquisition manager would be able to more thoroughly assess the life cycle cost of such ship modifications. Further, this data and analyses can justify pursuing ship modifications that improve energy efficiency. Ultimately, improved energy efficiency increases the ship’s mission capability .through increased range and time on station). Such data can also be used to substantiate the electrical load analysis of particular ships which is generally never verified. Understanding the true electrical loads on a ship is critical to evaluating the ship impact of adding new systems. In order to meet energy reduction goals, the energy use of ship systems and equipment needs to be measured and calibrated to the ship’s mission, ship’s readiness condition, and ship’s operational profile. Once data is collected and correlated, recommendations for operational policy changes, operational procedure changes, technology improvements or maintenance actions can be evaluated (Ref 1). Existing shipboard energy monitoring systems lack the ability to store, integrate, and assess shipboard energy use data. There is inadequate integration with other shipboard systems, and no capability to provide mission maintenance assessment. Commercial smart thermostats, such as ‘Nest’, provide a portion of this functionality, but only for residential heating and cooling systems (Ref 4). Industrial versions are available for buildings which expand control to lighting, but again fall short of full functionality. Maritime systems are being developed to meet new energy International Maritime Organization rules (Ref 5) that will meet a majority of the functionality. However, the maritime systems, for commercial and cruise ships, would need to be modified to include the unique warfare systems of naval platforms. The innovation provided by this topic also will allow energy use predictions by allowing the user to vary the energy use of particular systems or equipment to help evaluate the benefits of technology improvements. Current technology assessments are performed with class standard information, which may or may not be current. This product will provide the data and analysis tools to enable ship acquisition managers to make more accurate assessments of product improvements and technology insertions. Knowing the energy demand of existing ship systems will enable the acquisition manager to more thoroughly assess the life cycle costs of ship modifications. Understanding the true electrical loads on a ship is critical to evaluating the ship impact of adding new systems. Shipboard energy use analyses can justify pursuing modifications that improve energy efficiency. Ultimately, improved energy efficiency increases the ship’s mission capability by enabling ships to travel further with the same fuel capacity, reduce fuel costs, and reduce their carbon footprint. Such data can also be used to substantiate the electrical load analysis of particular ships. To reduce the amount of monitoring equipment required, it is envisioned that energy use surveys will be conducted on a statistically representative sample of ships within the same ship class. Establishing the appropriate set of ships to survey is critical to establishing a representative energy usage database (Ref 3). Once the appropriate energy use data is collected and correlated to specific ship missions, it can be analyzed to determine how energy can be used more efficiently. The techniques developed under this topic will be used to analyze energy use across similar ships performing similar missions. The techniques will identify system and equipment operational variations. For example, one ship may operate with a particular system secured while another similar ship performing the same mission may run that system, even though it is not necessary for the mission. Currently, software does not exist that can store, integrate, and assess shipboard energy data. Although individual parts may exist, they are lacking in overall functionality: they do not provide a complete meta-model storage environment, do not allow themselves to be easily integrated with other systems, or provide a mission maintenance assessment of the optimum operating configuration and identify deviations to that configuration. The software, to be resident on the ship for real-time analysis and to be interfaced to a shore based system, will also compare the energy use of the same systems and equipment across similar ships to identify excessive energy use due possibly to a required maintenance action or inefficient setting. The shore-based system will provide a repository for the class data and allow analysis of the data on shore. PHASE I: The company will develop a concept for a Shipboard Energy Monitoring and Analysis System that meet the requirements described above. The company will demonstrate the feasibility of the concept in meeting Navy needs and will establish that the concept can be feasibly developed into a useful product for the Navy. Feasibility will be established by analytical modeling. The small business will provide a Phase II development plan that addresses technical risk reduction and provides performance goals and key technical milestones. PHASE II: Based on the results of Phase I and the Phase II development plan, the small business will develop a prototype Shipboard Energy Management and Analysis system for evaluation and conduct energy use surveys on a statistically representative sample of ships within the same ship class for evaluation of the software. The prototype will be evaluated to determine its capability in meeting the performance goals defined in Phase II development plan and the Navy requirements for the Shipboard Energy Monitoring and Analysis System. System performance will be demonstrated through prototype evaluation and modeling or analytical methods over the required range of parameters including numerous deployment cycles. Evaluation results will be used to refine the prototype into an initial design that will meet Navy requirements. The company will prepare a Phase III development plan to transition the technology to Navy use. PHASE III: The company will be expected to support the Navy in transitioning the technology for Navy use. The company will develop the Shipboard Energy Monitoring and Analysis System according to the Phase II development plan for evaluation to determine its effectiveness in an operationally relevant environment. The company will support the Navy for test and validation to certify and qualify the system for Navy use. PRIVATE SECTOR COMMERCIAL POTENTIAL/DUAL-USE APPLICATIONS: This product has potential application across a variety of commercial sectors. The commercial shipping industry can take advantage of energy use analysis to determine the most cost-effective modes of ship operation. The data monitoring and storage elements of this product have application to many industrial scenarios where multiple systems or equipment are operating. The analysis portion of this product may need to be customized to a unique industry. However, any industry or government entity can use this product to establish energy use baselines enabling analyses aimed at reduction of energy use and operating costs. REFERENCES: 2.
