Commercial Diving: Should 4-Person Teams Become the New Norm?

Posted by Steve Pratt on Thu, Sep 19, 2019

Dive teams mobilize every day to complete a broad assortment of tasks utilizing a 3‑person dive team. Historically, this has been the standard not only within Brennan's practices, but for most other inland diving organizations. The Association of Diving Contractors International (ADCI) gives guidance that requires, at a minimum, a 3‑person dive team. While this practice is sufficient in some circumstances; such as non-penetration inspections and wheel jobs (propeller repairs); with our growing scope of work it became apparent that a 4‑person dive crew—adding a standby diver—should be our internal minimum standard moving forward.

I have been in the environmental industry for 32 years (wow that’s a long time), and I do not believe I have ever experienced this much activity. The size, scopes, and complexities of our current projects are overwhelming. J.F Brennan Company (Brennan) is extremely fortunate to have a very busy, robust workload this year with some exciting projects underway, and more that are set to begin once fish windows open. Based on our own surplus of work and activity, I wanted to share my observations and discuss the current state of the environmental community from a dredging contractor’s perspective.
