About this file
This document is a Statement of Work (SOW) for replacing the Steering Proportional Valves on the USCGC GEORGE COBB (WLM-564) cutter. The SOW details the background of the issue, which is that the STBD Z-drive could only be controlled in the CW direction, indicating a faulty solenoid. The Coast Guard Surface Force Logistics Center (SFLC) engineering recommends replacing both the Port and STBD Steering Proportional Valves, which should be configured per the Controlled Enterprise Incorporated VS8640-VB131B valve. This is a solicitation to procure 2 Steering Proportional Valves, which the vendor is required to ship directly to the USCGC GEORGE COBB in San Pedro, CA as soon as possible. The related federal contract opportunity is Solicitation Number 70Z08524P08121 for the "USCGC GEORGE COBB Z DRIVE STEERING", which is a total small business set-aside under NAICS Code 336611 with a 1250 employee size standard.

SOW for Steering Proportional Valve
USCGC GEORGE COBB (WLM-564)
1. Background: While patrolling in DPS autopilot, MPCMS annunciated a STBD Z-drive positioning alarm. Upon shifting to the Z-Conn steering mode, ships force noticed that the STBD Z-drive could only be controlled in the CW direction. After shifting to the emergency steering mode from ECC, the STBD Z-drive continued to spin CW without any control input. Ships Force (SF) disconnected all electrical control cables from the STBD directional control valve, and the Z-drive continued its CW rotation. Manual actuation of the solenoid resulted in slow operation in the CCW direction and normal operation in the CW direction. As part of the troubleshooting process, SF swapped electrical solenoids between port and STBD Steering Proportional Valves and the issue switched to the port Z-drive indicating a faulty solenoid. SFLC does not have any replacement Steering Proportional Valves on hand and OEM is no longer in business. Cutter is currently unable to meet full operational commitments.
2. SFLC engineering recommends replacing both Port and STBD Steering Proportional Valves.
