Towable Diving Systems

Phoenix’s Towable Diving Systems (TDSs) are compact, mobile, and rapidly deployable shallow-water diving spreads designed to support a wide range of dockside vessel maintenance and inspection tasks. These systems are optimized for operations in depths up to 60 feet of seawater (fsw) and are supported by an experienced 4- to 5-person diving crew.
TDS units are strategically positioned at our San Diego, CA; Chesapeake, VA; Davie, FL; and Bayou Vista, LA locations and can be dispatched to any port along the West, East, or Gulf Coasts. Once on site, the systems are quickly set up dockside, enabling efficient operations without the need to mobilize diving spreads onboard vessels—eliminating crane fees and reducing dock charges, providing clients with a cost-effective, flexible solution.
Typical Services Performed with TDS Units:

- Vessel Inspections (including photo and video documentation)
- Class-Approved Underwater in Lieu of Drydocking (UWILD) Inspections
- Hull Cleaning
- Propeller Straightening, Cropping, and Polishing
- Class-Approved Underwater Welding, Burning, and Cutting
