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.

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. The ice may have been thick - really thick - four to five feet thick. But that didn’t stop us from taking on the most demanding under-ice dive projects.

Stray current corrosion is a common threat to water-based steel structures such as barge terminals. Though hard to identify the source, damage from stray current can be prevented by following 3 simple steps.

Lock and Dams, bridges, pipeline crossings, and barge terminals are all examples of water-based infrastructure. Ensuring that these structures maintain their integrity is essential to their continued operation, however water-based infrastructure presents an added challenge because a portion of the structure is underwater.

Dredging around utilities is challenging, and mistakes can be expensive and dangerous. When utilities, such as power lines, natural gas lines or fiber optics, are above ground they can be easily marked, and a plan can be developed to avoid them. However, when these same utilities are underwater, locating them and working around them adds an additional layer of risk for the contractor.
