Vigor Shipyards, Pacific Northwest
eTrac has performed annual conditional surveys at Vigor’s Portland, Oregon and Seattle, Washington shipyards since 2015. eTrac utilizes high resolution multibeam for bathymetric surveys to determine safe depths for deep draft vessels transiting the shipyards. These surveys help Vigor maintain their facilities for safe navigation and plan for future maintenance. Precision navigational charts are also produced to assist Columbia River pilots at the Portland facility.
