NOAA leadership was joined by partners today to celebrate the keel-laying for Surveyor, a new charting and mapping vessel being constructed for NOAA. The vessel is being built by Thoma-Sea Marine Constructors, LLC., in Houma, Louisiana.
The keel-laying is a centuries-old maritime tradition that formally recognizes the start of a ship’s construction. During today’s ceremony, the initials of the ship’s sponsor, Tracey Brennan, the widow of NOAA Corps Rear Admiral Rick Brennan, were welded onto a steel plate that will be incorporated into the ship during construction.
In 2023, NOAA announced two new charting and mapping vessels would be added to the NOAA fleet. Surveyor is expected to be completed in 2027 and Navigator in 2028. The ships will be used primarily for ocean mapping and nautical charting as part of NOAA’s mission to deliver tools and information to help mariners safely navigate the nation’s ports and harbors.
“NOAA ships are instrumental in surveying thousands of square miles of our nation’s waters every year,” said NOAA Corps Rear Adm. Chad Cary, director of the NOAA Commissioned Officer Corps and NOAA Marine and Aviation Operations. “These new, state-of-the-art ships are another milestone in NOAA’s effort to recapitalize our aging fleet and ensure that we can continue to meet our mission to support safe navigation for years to come.”
The name Surveyor points to one of NOAA’s key missions — to conduct surveys of coasts and waterways — and it’s also the name of two former ships. Like its former namesakes, the new Surveyor will be homeported in Ketchikan, Alaska.
