J--Derrickboat Woodie Walden Crane Control Systems Upgrade

Solicitation W912BU-09-T-0064, issued by the U.S. Army Corps of Engineers, Huntington District, through the W2SD Endist Philadelphia office, is a total small business set-aside contract for the comprehensive upgrade of the crane control systems on the Derrickboat Woodie Walden. The project scope encompasses all phases of the upgrade, including engineering, design, integration, fabrication, delivery, installation, and testing. The primary objective is to replace obsolete GE Maxspeed Crane Drive System components, specifically the Silicon Controlled Rectifier (SCR) and Programmable Logic Controller (PLC), with current generation equivalents to ensure the vessel can continue supporting critical maintenance missions on the Ohio River. The technical requirements involve updating systems that manage high-capacity DC motors, including a 165 HP hoist motor and a 92 HP swing motor. The upgrade includes the implementation of a new encoder system and the modernization of existing GE Fanuc LogicMaster 1F PLC control logic and electrical schematics. To ensure successful execution, the contract required a detailed testing plan and the provision of training. The procurement process included multiple amendments to refine the scope of work and facilitate site visits at the Winfield Lock and Dam in West Virginia.
