Abstract: The systems and methods disclosed herein provide multiple solutions from maximizing efficiencies for propulsion and electrical plant equipment to reducing life cycle costs. Knowing how equipment is used/operated and how fuel is used to power equipment can increase awareness and can help to provide the best opportunity to maximize the technological gains in power generation. The systems and methods disclosed herein can provide such awareness by displaying current and projected fuel consumption attributable to specific factors encountered in operational conditions, including the environment, hull fouling, displacement and engineering plant modes. Systems and methods employ physics and quantitative based methodology that focus on assessing and quantifying fuel utilization impacts due to machinery employment, material condition disparities, abnormal configurations and excess usage.

Abstract: A digital-based control data processing system detects during system operation the occurrence of data processing errors. Data processing accuracy is verified by receiving output information developed from system input information in accordance with a first operational function, computing a derived version of the system input information in accordance with a second operational function, and comparing the derived version of the system input information to the actual system input information to determine whether they differ by a predetermined operational tolerance. This method for verifying processing accuracy is especially advantageous for detecting latent software errors which are unique to a particular computer program. The processing system includes display apparatus which develops from the output information a set of display symbols that convey the information on a monitor screen to the pilot.
