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

Posted by Steve Pratt on September 19, 2019

Dive teams mobilize every day to complete a broad assortment of tasks utilizing 3‑person dive teams. 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.

State of the Environmental Industry | June 2019

Posted by Andrew Timmis on June 20, 2019

We’re nearly halfway through 2019, and unless you’ve been in a cave or under a rock, you understand that the environmental market is exploding right now. 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.

Our team has withstood the most unpredictable winters in recent memory. As we finally head into warmer weather, we reflect on all we were able to accomplish under the ice this past season.

Posted by Jeff Steiber on November 27, 2018

At Brennan, we work on dams of various sizes and functions. Very few new dams are built each year, so most of our work consists of rehabilitation and repairs. Dams are built to last for long periods of time, however certain components require periodic repairs and replacements. Radial gates, often referred to as Tainter gates, consist of components most commonly in need of attention. In our experience, we have found certain best practices that will increase the longevity of these gates, as well as increase their functionality.
