We provide construction and maintenance projects for a variety of industries, vessel salvage and casualty response, vessel inspections, freshwater mussel surveys, diver-operated dredging and much more. In addition, our talented dive teams are routinely contracted to perform projects at nuclear, hydroelectric, and coal-fired facilities nationwide. Mainstream’s divers are some of the best in the industry with experience working in zero-visibility conditions, contaminated environments, confined spaces, potable water facilities, and ecologically sensitive areas. Mainstream meets or exceeds all OSHA, USCG, and ADCI Consensus Standards requirements. Mainstream was originally the combined entities of Mainstream Commercial Divers out of Murray, KY and Eason Diving & Marine Contractors located in Charleston, SC. In 2019 Mainstream joined the Moran group of companies and was rebranded as MER Commercial Diving. Returning to the original Mainstream name in 2021, today we – along with the Moran group of companies – offer a full range of services, skilled personnel, equipment, and project expertise to clients across the U.S.
