Miscellaneous ship and marine equipment

The Department of the Navy Naval Supply Systems Command is procuring a critical spare part for Carrier Strike Group Four - specifically a Port Z-Drive primary steering Variable Frequency Drive (VFD) controller for the TSV5 Vindicator vessel. This procurement includes one complete set of SCHOTTEL Modernization Equipment Controls, consisting of steering units, main and backup steering VFDs, a control PLC, and additional smaller components to restore redundancy to the ship's propulsion steering system. The Z-drive marine propulsion system provides 360-degree thruster rotation for superior vessel maneuverability, while the VFD controller enables precise control of rudder movement with benefits including reduced power consumption and increased system reliability. Potential contractors must be registered in the System for Award Management (SAM) database and should submit capability statements through beta.SAM.gov. The solicitation was posted on August 5, 2025, with offers due by 3:00 PM on August 8, 2025, providing contractors with an extremely tight three-day response window.

This procurement is designated as a small business set-aside under NAICS code 336611 (Shipbuilding and Repairing) with a size standard of 1,300 employees, though a sole source justification document indicates SCHOTTEL Marine Technologies as the Original Equipment Manufacturer with proprietary control systems. The total contract value is $93,093.00 for this firm-fixed-price procurement, with a performance period running from July 30, 2025, to September 30, 2025. The equipment must be delivered by September 30, 2025, to Carrier Strike Group 4 at Joint Expeditionary Base Little Creek in Virginia Beach, Virginia. The sole source justification emphasizes SCHOTTEL's patents on electronic force feedback steering systems with specialized software, proprietary bus communications, and microprocessor control that integrate uniquely with the vessel's navigation infrastructure. This critical procurement aims to ensure the operational readiness of the TSV5 Vindicator's propulsion and steering capabilities.
