HEALY-SLEP Industry Day – Deaerating Feed Tank (DFT), PLC-Based Steering Control System Replacement
The Government is seeking industry feedback on the following two distinct work packages:
Requirement 1
Deaerating Feed Tank (DFT), Feedwater Treatment, & Boiler Controls
• Design, furnish, and install one (1) new Deaerating Feed Tank (DFT) and associated feedwater treatment system.
• Renew the existing obsolete boiler Programmable Logic Controller (PLC) and burner sequencing controls.
• Deliver design documentation and integration components to support prototype installation during the FY2028 Availability.
Requirement 2
COTS PLC-Based Steering Control System Replacement
• Replace the existing steering control system with an open-architecture, commercially available off-the-shelf (COTS) PLC-based design.
• Interface new controls with existing auxiliary and navigation systems.
• Replace or upgrade all electronic components and sub-systems, including Rudder Servo Amplifiers (RSA), Rudder Repeat Backs (RRB), Rudder Angle Transmitters (RAT), and Steering Failure Alarm (SFA) panels to retain full capabilities without requiring exact legacy duplication.
