Abstract:

This design data sheet DDS provides procedures for preparing an Electric Power Load Analysis EPLA for conventional-powered fossil fueled surface ships. However, this DDS may be used as a basis for preparing a load and power analysis for a ship powered by other means. The EPLA, also referred to as the Electric Plant Load Analysis or the System Load and Power Analysis, is used as an input for determining the power requirements for electrical generation, energy storage, and power conversion components and equipment and current requirements for electrical distribution equipment and components. The EPLA is also used to develop 24-hour average electrical load estimates for calculating fuel endurance and annual fuel consumption. The process of creating an EPLA is generally composed of two steps First, identifying, compiling, estimating, and categorizing all of the electrical loads on a ship and second, using an algorithm to combine the estimated loads to determine the design requirements for electrical system components and equipment.
