Marine Surveys & Inspections

CoTs is proud to offer full hydrographic and bathymetric surveys, ranging from deep-water to the difficult to operate in littoral surf-zone environment.   We leverage state-of-the-art sensor technology to provide our customers with precise and accurate imaging in even the strictest of survey requirements.   Through our partnership with Theory Marine Services, LLC, we are equipped with a specialized USCG safety inspected & compliant survey vessel designed for ROV and survey operations, including a large on-board winch. 

Pipelines are a key infrastructure for many industries, including Power Generation, Manufacturing, Oil & Gas, Hydroelectric Plants, etc. Using our fleet of ROV systems, we are able to inspect pipelines and tunnels, large and small diameter.  We offer a sophisticated system for the inspection of water flooded conduits, penetrating distances of up to 10,000ft (further distances possible on request) through access points as small as 19” manholes.  We leverage our technology to increase efficiency in nominal inspections and make “impossible” inspections possible. 

Through our partnership with SeaView Systems, conduit investigation has been a core work for us from workshop setup through mobilization, onsite setup, operation, demob and report.  We have a developed and mature system to ensure we maintain a high quality of service.
