Seanic Ocean Systems

What Seanic Ocean Systems does

Centurion Subsea Services, operating under parent Centurion Group Ltd. and DBA as Seanic Ocean Systems, designs, manufactures, rents, and services specialized subsea intervention equipment for the offshore oil and gas industry. The company was formed through the combination of Aleron and Seanic UK's engineering expertise and maintains its US headquarters in Katy, Texas. Its product portfolio spans ROV (remotely operated vehicle) tooling packages, diver-operated tools, cutting and decommissioning equipment (shear cutters, saws, grinders, drills), lifting and recovery tools (grabs, hydraulic shackles, chutes, sheaves), hydraulic power systems (HPU, diesel/petrol units, air-powered units, hose reels), torque tools, intervention tools, and topside/deck equipment including winches, tensioners, and spoolers. The underlying technology is mechanical, hydraulic, and electromechanical, with products marketed under a 'Simple, Rugged and Reliable' quality standard and supported by a full-service test tank and welding facility at Katy.

The company monetizes through five revenue streams: (1) one-time sales of standardized equipment, (2) recurring equipment rentals, (3) professional engineered solutions for custom tooling challenges, (4) managed field services including IMR (Inspection, Maintenance, Repair) programs, and (5) storage and integration services at its Katy facility. Customers are concentrated among major international oil and gas operators and subsea service companies requiring tooling for ROV operations, diver operations, cutting/decommissioning, and deck operations. The go-to-market model is direct sales-led through a consultative website enquiry system, supplemented by channel partners (Jacks Winches) for hire services in Australia and Singapore. Global presence spans the United States, United Kingdom, Australia, and Singapore, with the Jacks Winches brand retained following acquisition to serve the APAC market.
