Offshore Positioning
Our hydrographers provide offshore positioning for support of construction, science and resource exploration.
We have the systems and experience to position multiple objects and support oil rig moves, pipeline, outfall or cable installation, as well as scientific endeavors including tracking manned and unmanned submersibles, trawls, acoustic measurements and other activities.
