About this file
This document is an electrical load calculation spreadsheet for the Gladys Reese EPLA (Electrical Power Load Analysis) for a marine vessel, prepared by engineers Michael Loboda and Ian Lawson. The spreadsheet details electrical demand loads across six different operating conditions: summer cruising, winter cruising, summer functional general, summer functional camera array, winter functional general, and winter functional trap video. The analysis covers multiple electrical panels including ACP (HVAC 440V Panel), ELP (Engineering Lighting Panel), MLP (Compartment Lighting & Receptacles Panel), MNL (Mission Lighting Panel), MPP (Mission Power 440V Panel), and others, with comprehensive load factor calculations for various equipment such as pumps, compressors, fans, lighting, receptacles, and specialized marine equipment. The total demand load ranges from 82.6 kW to 158.7 kW across different operating conditions, with load factors varying by equipment type and operational mode, and calculations performed in accordance with IEEE, PRG, and NFPA standards.
