In December of 2001, Rogers Surveying began to perform single beam hydrographic surveys and volume computations of the New Jersey Marine Terminal in Port Newark for the Port Authority of New York and New Jersey under an “On Call” contract. The initial assignment was to perform a hydrographic survey for sixty-two (62) berths, twice a year with dredge templates created and volumes calculated.

Using differential GPS for positioning and single beam sounding technology, our surveying vessel was mobilized and ready to survey within an hour of a call by the Port Authority.  Being a very busy commercial docking facility, the berths were surveyed as they became vacant, subsequently many visits to the site were necessary and onboard editing and quality control checks maximize turnaround of the hydrographic data.  Initial goal was to complete five berths a day.

After our acquisition of multibeam our productivity and turn around time increased greatly, the multibeam survey would not only provide more accurate data but also in minimizing the time the berth would be unavailable due to surveying. The state of art navigation system onboard the RED ROGERS allows surveying beneath the large overhead gantry cranes possible.

Today, Rogers Surveying performs multibeam and sidescan sonar surveys for sixty-two (62) berths, twice a year with volumes calculated
