Paper Abstract

The Amphibious Assault Ship, USS Makin Island (LHD 8) encompasses multiple systems to support the Navy's missions. The USS Makin Island systems include ballast, steering, propulsion, fresh water, power distribution as well as many damage control systems. The systems utilize various signal types to operate the systems while receiving signals to monitor the system components via the Machinery Control System (MCS). Many input/output (I/O) signals exchange information between the MCS and the various systems' equipment. The MCS monitors and controls the system components using a Human Machine Interface (HMI). The user-friendly HMI permits authorized operators to perform many daily operations remotely allowing operators to address system issues from multiple MCS units located throughout the ship. The MCS utilizes a fiber optic network that serves as the backbone connecting the Local Area Network (LAN) switches via blown optical fiber. Each MCS unit is intricately connected to the LAN switches for maximum redundancy via fiber optic connections to non-adjacent LAN switches to ensure system communications continuity. The LAN switches are connected in a star configuration for added system survivability. The backbone's blown fiber is designed and installed with a sufficient percentage of spare blowing tubes to ensure the potential of future growth. Conventional optical fiber is used to interconnect the MCS consoles, workstations, and Data Acquisition Units (DAU) to each other and the LAN switches. The conventional fiber also contains sufficient spare conductors in a combination of eight and four conductor optical fiber. The network backbone is redundantly connected allowing for continuous transmission of information throughout the ship.
