Surveying a Tunnel Using an ROV

摘要

The system has been used to make three runs at La Higuera and two at La Confluenria.The system always collected information of value, and during operation in March 2014 where both the La Confluencia and La Higuera tunnels were inspected, the system performed without issue. The continual improvement and application of remote technologies to asset management projects can help reduce overall inspection costs, eliminate the risk to inspection personnel and eliminate structural risks associated with dewatering a tunnel. The level of detail that can be obtained, even in zero visibility water, can be used to detect small isolated rocks or debris so that intervention can be planned in advance rather than in an emer-gency response.The ROV will continue to be used to provide assurances to all stakeholders that the tunnel can be effectively monitored without the need to dewater.
