Underwater inspections can be accomplished using divers, sector scans, or a remotely operated vehicle (ROV). Brennan can provide several options to best supply detailed information on many types of underwater structures in almost any environment. We distinguish ourselves from other inspection firms because our team members have construction experience. Our divers know how to identify problem areas on bridge piers and recommend solutions for cost-effective repairs.

Dive Inspections
- J.F. Brennan Company divers are all certified commercial divers with extensive experience in water-based infrastructure. Each team member understands the construction process and can recommend cost-effective solutions that will ensure a quality bridge repair. – Learn More

Sector Scans
- Sector scans are used to create an underwater acoustic image of an object or structure. These images are then used to assess the visual condition of a bridge pier without the need for a dive inspection. – Learn More

Remotely Operated Vehicle (ROV)
- Brennan’s ROV can perform underwater inspections in areas and conditions in which diver access is limited. The Brennan ROV is operated by a trained professional and can record high-resolution video in even the smallest and darkest conditions.
