Induction Furnace Overhaul – Naval Shipyard, PA
At a naval shipyard in Pennsylvania, Byers delivered a fixed-rate electrical program to overhaul induction-furnace infrastructure. Work planning emphasized lockout/tagout, safe de-energization, and weekday 10-hour shifts (7:00 a.m.–5:00 p.m.) to coordinate with parallel activities while maintaining schedule and quality.
Scope included LOTO on transformer primary and controls; de-termination of primary/secondary conductors; selective removal of 4″ rigid conduit between the existing switch and transformer; temporary removal and re-installation of (2) ¾″ EMT conduits and a receptacle for wall work; removal of legacy equipment and transformer; and primary reconnection from the existing switch to a new isolation transformer. The team installed EMSCO cable tray from the new transformer to the new equipment, cored four 8″ floor penetrations, routed 24″ tray to each core for #500 conductors, and added 24″ solid-bottom tray down to two 36×36×24″ NEMA 12 enclosures with covers and flanged entries. New cables were terminated from the transformer secondary to inverter terminations, with vendor ground busbars installed between switch and inverter and a new ground bar near the transformer tied to a ground rod, then bonded per the grounding plan
Execution followed drawing clarifications and delineations—certain inter-equipment cabling and auxiliary-pedestal power/control by others; pump/motor-starter scope excluded—while core drilling, tray bonding, and grounding were sequenced to protect existing systems and streamline commissioning. The result is a clean, maintainable high-voltage and controls backbone for the furnace system with clear isolation points, organized cable routing, and robust grounding to support reliable shipyard operations.
