380 FT Towing Tank Carriage Control System

Summary (Newest Update)

Background The Naval Academy Hydromechanics Laboratory (NAHL) at the United States Naval Academy (USNA) operates a 380 FT towing tank that supports various activities primarily focused on Naval Architecture and Ocean Engineering courses, as well as diverse student and faculty research. The goal of this procurement is to purchase a new carriage control system for the towing tank to enhance operations and mitigate technical risks associated with future investments. Work Details The contract involves the purchase and installation of a new carriage control system for the NAHL 380 FT Towing Tank, which includes a user interface console and associated operating software. The system will control existing drive motors and regenerative braking while incorporating new position sensing equipment. Key specifications include: - **Normal Speed Control**: Accelerate from parking spot to desired speed, hold speed, decelerate automatically, and return to parking location at operator-determined speed. - **Programmable Speed Changes**: Ability to test multiple speeds during a run with manual override options. - **Position Move Control**: Select specific locations along the tank for carriage movement with independent speed settings. - **Jog Control**: Operator can command carriage movement at selected speeds for maintenance procedures. - **Control Capabilities**: Speed range from 0.01 to 40 ft/s, acceleration/deceleration from 0.01 to 16 ft/s², emergency stop capabilities, and pulse feature for data collection integration. - **Software Requirements**: Graphical user interface with help features, history/error logging capabilities, and synchronization with wavemaker signals. - **Electrical System**: Utilizes existing power distribution systems with safety measures against over voltage and short circuits. - **Maintenance Requirements**: Contractor must provide training manuals, troubleshooting guides, and ensure minimal maintenance downtime.
