ROV Cobia


Overview

LUMCON owns and operates the ROV COBIA, a Deep Ocean Engineering (DOE) Phantom HD2 survey class Remotely Operated Vehicle (ROV). The ROV COBIA, along with the rest of LUMCON's research fleet, is administered through the Marine Operation Office at the marine center in Cocodrie Louisiana. The ROV can be leased independently or along with LUMCON's vessels R/V Pelican and R/V Acadiana.

The ROV COBIA is available for research and education programs of Consortium members, state and federal agencies, other non-profits, and oceanographic industries.

The ROV COBIA is a dependable ROV ideally suited for offshore surveillance and light work tasks.

This extremely robust design can handle moderate currents down to 300m (1000 ft). In it basic configuration the ROV dives with two high-resolution color cameras and lights, one fixed and one on a tilting mount. A DOE single function manipulator is carried on the lower forward right side. The ROV COBIA has power and room to spare, so mounting and supporting guest instrumentation is easily accomplished. CTD's, HD Sonar, diver support, and more have been performed successfully off this platform. Using survey grade navigation equipment the ROV's position can be logged and plotted at all times.
