The Rigger's Crucible: How Hands-On Training Builds a Professional
May 7, 2026 — Amidst a maze of piping, cables, and tight submarine passageways, an electric motor suspended inches from the deck makes its way towards its new location. A team of skilled shipyard workers executes a seamless dance of communication and physics to move the heavy motor through a tight scuttle. Swinging the motor between two chain-falls, the way Tarzan moves through the jungle canopy, each line takes the load in turn, every move purposeful, each person in sync as the load shifts between chains. These men and women are known as riggers, and they are the experts at Pearl Harbor Naval Shipyard and Intermediate Maintenance Facility when something needs to be moved safely and efficiently, no matter the size. ...
