The US NAVY DDG 51 Class Machinery Control System (MCS) provides control and monitoring capability of the ship's auxiliary, damage control, electrical, and propulsion systems. As part of its electrical capability, MCS interfaces with the ship's power generation and electrical distribution system. This paper focuses on MCS' interface with the ship's power generation equipment and how the interface has evolved since the class' inception. The DDG 51 class has been in-service for nearly 2 decades and consists of over 60 ships. Over this period, a number of enhancements have been made to equipment on the ship to increase its functionality, enhance its operator interfaces, and address obsolescence issues. The Ship's Service Gas Turbine Generator (SSGTG) local controller is one such piece of equipment that has evolved throughout the years. Each SSGTG local controller upgrade has provided an opportunity for MCS to evolve to provide additional capability and data to the end user.
