FAQ

ROV stands for Remotely Operated Vehicle, which is essentially an underwater robot connected to a tether which is piloted by an operator above the water’s surface. Using a series of propellers, ROV’s are unoccupied units, which are highly maneuverable. The tether carries power and operating signals to the ROV, and transfers information back to the surface such as video feed, sensory information, and ROV status information.

Although an ROV does not have the capability to replace a diver, they certainly have their advantages and their own application which may be outside the scope of an area where a diver can perform. An ROV can provide virtually unlimited bottom time, as well as having observation capabilities to areas which may not be obtainable by a diver. The systems housed in an ROV have precise navigational controls, which are well utilized in conducting various underwater inspections and surveys.

The main difference between Surface Supply and SCUBA is your air source. With Surface Supply diving, the air source for the diver comes from either an air bank on the surface, consisting of several large air bottles which connect into an air panel, or with an air compressor that pumps air down to the diver. SCUBA, on the other hand, employs a single air tank that a diver will wear underwater as their main air source, often times with a second smaller air cylinder attached to the main air source. Both Surface Supply diving and SCUBA diving have their own standards and regulations set out by CSA which regulates occupational diving safety standards in Canada (Welding, Use of power type tools, and work in or around outfall / intakes is prohibited with SCUBA).

 

The commercial dive staff at CDMS  meets or exceeds the standards set forth in C.S.A. Z275.4-97 (Competency Standards for Diving Operations) and C.S.A. Z275.2-92 (Occupational Safety Code for Diving Operations).  Our divers and supervisors are Dive Certification Board of Canada (DCBC) certified.
