Emergency Diesel Generator Maintenance

Statement of Work Page 1 of 6 Section A: Scope 1. Objective: Norfolk Naval Shipyard (NNSY) requires preventive maintenance on each of the NNSY Centralized Pier-Side Pretreatment Unit (CPPU) Emergency Diesel Generators (EDG). 2. Background/Introduction: The MDG250 EDGs are utilized during planned/unplanned power outages to maintain power and operations to the CPPU Facility. These EDGs are standby equipment and require regular preventive maintenance to ensure full operational status when needed. Malfunction of these EDGs will have negative impacts on the mission of NNSY.
