Towable Diving Systems (TDS)
Phoenix’s Towable Diving Systems (TDS) are designed for speed, mobility, and efficiency. These compact, shallow-water diving spreads support a wide range of dockside maintenance and inspection tasks. Each system is supported by a skilled diving team that can perform works to 60 feet of seawater (fsw).
We strategically position TDS units in Chula Vista, CA; Chesapeake, VA; Davie, FL; and Bayou Vista, LA. As a result, we can quickly dispatch them to ports along the West, East, and Gulf Coasts. Once on site, crews set up dockside in a short time. This eliminates the need to mobilize equipment onto vessels. In turn, clients avoid crane fees and reduce dock costs—creating a more flexible and cost-effective solution.
