Phoenix International, Inc., (Phoenix), a marine services company specializing in underwater operations and engineering, celebrates its tenth year of business this month. The company began with a staff of eight, conducting underwater ship repairs for the US Navy’s Supervisor of Salvage and Diving. Phoenix continues to perform waterborne ship repairs for the Navy (and others), and has augmented its services to include underwater inspections and surveys, search and recovery missions, marine construction support, submarine rescue operations, and entertainment production assistance. In-house engineering expertise provides operations with technology and procedures to improve underwater work efficiencies. The multi-disciplinary engineering staff also designs products to meet unique needs, often incorporating the results of internal research and development in pressure tolerant electronics and high energy density secondary batteries and battery monitoring systems.
