Underwater Drone (ROV) Asset Review and Documentation
Many New Hampshire Department of Transportation (NHDOT) assets that can be documented with drones have a portion below the surface of the water that is difficult or impossible to see and document. These assets can include but are not limited to bridge abutments/piers, box culverts, cofferdams, and beaver mitigation devices. In emergency situations a below water surface view of an asset could be needed in a rapid timeframe to determine the stability of the asset. Also, during construction of below water surface assets there is difficulty documenting the actual completed condition or supporting trouble shooting when issues arise during construction. This research will evaluate several cases of NHDOT underwater asset review and documentation and include the purchase of an underwater drone (ROV) and appropriate support equipment. The case studies, solicited from throughout NHDOT representing the potential diverse use of this technology, will detail the evaluation, challenges, and benefits of the data acquired with the underwater drone (ROV). The potential savings of underwater drone (ROV) data providing targeted areas for divers to inspect an asset where in-person inspection is required will also be evaluated. The use cases will include the types of data needed by the Department’s asset stakeholders along with an evaluation of the equipment’s capabilities. The study will identify pros and cons to using this type of technology for the safe, efficient, and cost-effective underwater asset review and documentation needs of NHDOT.
