Hydroelectric Dam Underwater Inspection
MER Commercial Diving Division (formerly Mainstream Commercial Divers, Inc.) was awarded the contract to provide underwater inspection and repair services to the hydro units 1, 3, and 5 water intake screens and structures at a hydroelectric dam facility in Virginia.
Due to water depths of as much as 200 feet, portions of the work was performed utilizing mixed gas diving operations (heliox) and an open bell system.
