Gulf of America - Uncrewed Surface Vessel Operation --- --- SeaTrac Systems, Inc., will deploy an Uncrewed Surface Vessel (USV), the SP-48, to conduct ocean data collection approximately 120 nautical miles east of South Padre Island, TX. The USV will collect oceanographic information via onboard sensors from an operational data collection site bound by the following approximate positions: 26-30.33N 095-15.83W, 26-30.33N 094-19.23W, 25-45.00N 094-19.23W and 25-45.00N 095-15.83W. The USV will launch from Port Isabel, TX, and will be escorted by a support vessel to an area outside the Brazos Santiago Entrance Channel. The USV will then head east, under the supervision and control of the remote piloting team, to the data collection area. The SP-48 will spend approximately 10 days collecting data offshore. After data collection is complete, the USV will be remotely piloted back towards South Padre Island and meet with an escort vessel for the nearshore transit inland. The SP-48 is a solar powered 4.8 meter USV, with a cruising speed of 3 kts and a top speed of 5 kts. The USV is equipped with an AIS transceiver, running lights, a yellow signal flag to aid in observability, and is marked with “UNCREWED” on the transom. Mariners are requested to maintain a wide berth from the operating USV. POC: (978) 578-6645 or [email protected]
