Coast Survey uses unmanned technology to find submerged danger to navigation

AUV preparation

Coast Survey has been discovering and marking the locations of underwater dangers since our surveyors took the nation’s first official ocean soundings in 1834. We’ve used or developed all the technological advancements – lead lines, drag lines, single beam echo sounders, towed side scan sonars, and post-1990 multibeam echo sounders – and now we can point to a new major advancement for fast deployment and quick recovery. In February, Coast Survey’s Mobile Integrated Survey Team (MIST) used an autonomous underwater vehicle (AUV) to locate a submerged buoy that was interfering with anchorages in the Chesapeake Bay.

“You and the crew of the HASSLER put us right where we needed to be!” said a confirmation email from the U.S. Coast Guard to NOAA Lt. Ryan Wartick, one of Coast Survey’s navigation managers. “Thanks for the great work!”

NOAA’s navigation assets complete primary post-Sandy assignments, remain available to assist

NOAA continues to work in partnership with other federal, state, and local partners in response to the devastation of Hurricane Sandy. NOAA’s efforts are focused on navigation surveys to restore maritime commerce; aerial surveys to assist in those efforts and to aid on-the-ground responders from FEMA and local authorities; and in oil spill cleanup and damage assessment.  NOAA’s National Weather Service is also keeping authorities aware of changing weather conditions that could impact recovery and response efforts.

NOAA’s hydrographic survey vessels, including two three-person navigation response teams (NRTs) and the NOAA Ship Thomas Jefferson with her two survey launches, have completed surveys of the Port of New York and New Jersey. Working over the past five days, the high-tech vessels searched approximately 20 square nautical miles of shipping lanes, channels, and terminals to search for dangers to navigation.

Coast Survey navigation managers were embedded with the Coast Guard Maritime Transportation System Recovery Unit for the Port of NY/NJ, coordinating NOAA’s survey response. Lt. Brent Pounds, NOAA, explains ongoing survey operations to one of the port’s terminal operators during the height of operations.

Surveys continue in Port of New York / New Jersey, completed in Virginia

Coast Survey’s major survey operations in response to Sandy are completed in Port of Virginia, allowing port operations to resume. That timely resumption is proving to be vital for East Coast shipping, as the port is now receiving cargo diverted from the Port of New York and New Jersey. Associated Press is reporting that more than a thousand containers were offloaded in Virginia yesterday, with more on the way.

Meanwhile, critical survey work continues in the Port of New York and New Jersey, with two of Coast Survey’s navigation response teams (NRT) and two of the Thomas Jefferson launches continuing their search for dangers to navigation in shipping channels and terminals. Today, the high tech survey boats attached to the Thomas Jefferson surveyed the East River, as the ship processes data for delivery to the Coast Guard. One of the boats then went to survey Church Hill Channel this afternoon, while the other went to Gravesend Bay. NRT 2 is surveying Port Elizabeth and Port Newark in Newark Bay. NRT 5 surveyed Kill Van Kull and then proceeded to Author Kill.

NOAA Ship Hassler starts post-SANDY survey of deep draft routes to Hampton Roads and Baltimore

NOAA Ship Ferdinand R. Hassler departed from NOAA’s Marine Operation Center in Norfolk this morning, to start post-SANDY surveys of critical deep water channels.

NOAA’s newest survey ship, the Ferdinand R. Hassler, began survey operations today in support of the U.S. Coast Guard efforts to re-open the Port of Virginia. Hassler was in port at NOAA’s Marine Operations Center – Atlantic in Norfolk, Virginia, for maintenance when Hurricane Sandy affected the area. The ship’s crew spent Monday completing the work and system tests necessary to get underway once the storm passed, and has now been returned to limited operational status.

NOAA deploys personnel and survey assets to speed resumption of shipping after Sandy – Update 29 Oct

Coast Guard and Coast Survey at NY-NJ
USCG Lt. Cmdr. Anne Morrisey, chief of Waterways Management Division for Sector New York, and NOAA Coast Survey navigation manager Kyle Ward discuss potential navigation response scenarios, at Sector NY Coast Guard Maritime Transportation System Recovery Unit.

As conditions go downhill, NOAA is deploying personnel and hydrographic survey assets to help speed the resumption of shipping after SANDY clears out.

Coast Survey has deployed navigation managers from outside Hurricane Sandy’s areas of impact, supplemented with headquarters personnel, moving them to areas expected to be hit hard. Navigation managers are now at U.S. Coast Guard Incident Command Centers for New York – New Jersey and for Delaware Bay. We are also working with Coast Guard Captains of the Port for Virginia, Baltimore, and New England. NOAA’s navigation managers are working with the Coast Guard and the Army Corps of Engineers to coordinate deployment of NOAA’s navigation response teams (NRT) for rapid maritime response. They are also identifying vessels of opportunity, for potential use with Coast Survey’s mobile survey team (MIST).

NOAA pre-positions survey assets for SANDY maritime response

BHII in Hampton Roads 2011
Bay Hydro II surveyed in Hampton Roads following Hurricane IRENE last year, speeding the resumption of port operations.

As Hurricane SANDY heads north along the Atlantic coast, NOAA’s Office of Coast Survey is deep into preparations for maritime rapid response. Two objectives stand out: move navigation response personnel and assets into position to move quickly once SANDY moves out; and batten down survey vessels, to protect them from storm damage.

Coast Survey regularly responds to requests for quick navigation surveys after storms and other damaging events, pulling vessels from their normal survey schedules and deploying them to ports that need hydrographic surveys before they can resume full-fledged shipping.

NOAA survey teams wrap up response to Hurricane Isaac, return to normal duties to protect ships and people

As Gulf ports in the path of Hurricane Isaac bring operations back up to normal, Coast Survey’s navigation response team has finished its hydrographic surveys at Port Fourchon and is heading back to its regularly scheduled 2012 survey of the sea floor in the Port of Houston and Galveston Bay navigational areas.

Port Fourchon started allowing ships to enter the port yesterday, after NRT4 found only minor shoaling and no underwater debris that would pose a danger to navigation.

NOAA surveys ports to keep navigation safe and efficient. As Coast Survey’s navigation response team was wrapping up its surveys of Port Fourchon and Belle Pass on August 31, the pilot of the multi-purpose supply vessel HOS Achiever, inbound, asked if they found any dangers to navigation. The team found minor shoaling but no hazards.

NOAA navigation response team has a harrowing start to a successful afternoon of surveying at Port Fourchon

Coast Survey navigation response teams know the meaning of “rapid” in Rapid Maritime Response, as their ongoing response following Hurricane Isaac demonstrates.

As we explained in yesterday’s post (NOAA looks for dangers to navigation at Port Fourchon), getting a navigation response team (NRT) into the water at the port, to search for underwater debris and shoaling ‒ ASAP ‒ was Coast Survey’s highest priority. It was also a priority for port authorities, who know more than anyone how important it is to resume maritime operations quickly at “The Gulf’s Energy Connection.”

NOAA looks for danger to navigation at Port Fourchon, the “Gulf’s Energy Connection,” helps port resume operations

A rapid maritime response by NOAA’s Office of Coast Survey will likely pay dividends to the U.S. economy, as a high-tech survey team today began surveying the channels of Port Fourchon, the “Gulf’s Energy Connection,” to search for dangers to navigation caused by Hurricane Isaac.

Coast Survey’s navigation response team, in the water at Port Fourchon, started searching for underwater dangers to navigation today, speeding the resumption of shipping.

“Time literally means money for U.S. consumers when it comes to navigation through many of the Gulf of Mexico ports,” said Rear Adm. Gerd Glang, Office of Coast Survey director. “In this case, when a port can’t service offshore oil rigs, everyone — and most especially consumers — gets hit in the wallet.”

Ready, set…

Coast Survey’s Rapid Maritime Response assets for Hurricane Isaac are now in place, and are ready to move in when the storm moves on.

The teams will search for underwater debris and other dangers to navigation in port areas, to speed the resumption of shipping in areas impacted by the storm. A rapid response — that gives Coast Guard officials vital information on the condition of ship channels — reduces economic losses in maritime trade, reduces potential disruptions in energy supplies when ports are serving energy providers and oil rigs, and keeps mariners safe.
