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.

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.
According to the United States Department of Transportation, underwater scour is the leading cause of bridge failure, ahead of collisions and overloading. Scour is the erosion or removal of a streambed or bank material from bridge foundations due to flowing water. As many bridges sit over water, the potential dangers of scour cannot be ignored. There are many solutions to scour problems. However, there are two options that we find the most effective.
Traditionally when it comes to installing sheet piling around a bridge pier or along an embankment we think of steel sheet piling. Steel sheet piling are the most common, and have been one of the most effective methods of installing a deep foundation. They have a long history of providing a robust barrier through shaped, interlocking sheets that can last for 75+ years.
