ROV stands for remotely operated vehicle. They are highly maneuverable unoccupied machines used to observe and work underwater, often in areas that are deemed too dangerous for commercial divers. ROV pilots can operate them from a nearby shore or boat.

Remotely operated vehicles are versatile tools commonly used in our industry to inspect, monitor underwater structures, and perform complex work tasks in depths divers cannot access. Although, more recreational ROVs are available with advancements in technology. These revolutionary machines are utilized by many industries to reduce costs to clients and keep divers safe in unknown or dangerous conditions.

As a marine solutions company, J.F. Brennan Company, Inc. (Brennan) faces a unique array of regulations and rules. While every company deals with regulations, most deal with rules that impact operations only on land or only in the water. We are accountable for regulatory requirements in both areas and have been for years. So, what's changed and what are we doing about it?

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.

Working around water poses a plethora of challenges. There are always two parts of a water-based project, the above and below water sections. Access to the above water section is easy, however when working below the waterline access is not that easy. One of the more apparent issues is what do you do when the water is in the way of your work? One solution is to build a cofferdam.

Save Money with This Long-term Fix for Scour Problems

Scour poses a large threat to the stability of any structure that is partially or entirely underwater. It may develop slowly over time, or be brought on quickly by an intense rain event or seasonal flooding. In some cases, such as along a shoreline, scour can be very evident. In others, scour can go unnoticed for an extended period of time. Whether it is taking place around the footing of a bridge pier, along the base of a sheet pile wall, or along a tailrace on a dam, scour may not be evident until the structure begins to show signs above the water. At this point, the structure is beginning to fail and repairs must be done soon to avoid a total loss of integrity. Repairing scour and erosion issues that may be going unnoticed in any location is vital as it will save a lot of money in the long run, and extend the life of the structure.
