The maintenance and inspection of energy generation facilities has been a core business for Hibbard Inshore for many years. Whether the generation is coming from a coal burning plant, nuclear facility, hydroelectric dam, pumped storage plant or offshore wave, tidal or wind farms, Hibbard Inshore can utilize its ROV fleet to lower costs for inspections, maintenance, and installations of new equipment.
Inshore
Typical ROV applications for inshore generation plants include inspection and/or construction work on long range conveyance tunnels, diversion tunnels, penstocks, intakes, lower outlets, face of dam, reservoir bathymetry, trash racks, head gates and seals, turbines, turbine shut off valves and cooling water systems. In addition, Hibbard Inshore performs ROV controlled dredging, debris removal, and bulkheading at these facilities. Because the ROV's have an unlimited bottom time, the ability to operate in low or zero visibility conditions, facilities do not have to be dewatered, and often times adjacent units can be left running. Many of our customers find using a ROV for these services to save significant time and cost over traditional methods.
Offshore
For offshore generation, Hibbard Inshore can partner with your company from pre-installation throughout the life of the generating equipment. Through our experience, we are able to help our customers avoid potential project hazards and uncertainties as well as to practice effective maintenance while operating in the open water.
