Working in a highly-dynamic and demanding environment such as the transition zones (TZ) of Alaska’s Cook Inlet is tough. The region experiences the largest tidal range in the United States, and one of the largest in the world. This environment makes it extremely difficult to accurately deploy marine seismic sensors to a certain degree of accuracy. NCS SubSea has developed and continues to improve upon our methodology for positioning equipment during deployment. The ability to track and monitor gear as it goes through the water column is essential to positioning in the fast moving waters of Cook Inlet.
The North Slope of Alaska is limited to only a few brief months of open water, while the ice recedes. NCS SubSea is able to quickly mobilize and calibrate for marine seismic operations, by supplying a highly-trained navigation team and positioning equipment for large-scale projects. Acoustic and first-break positioning methods were used to precisely determine the location of the hydrophone in a depths less than ten feet.
