Post-SANDY navigation response in full swing   1 comment

NOAA’s navigation response teams and other survey assets are in the water (or soon will be) as they respond to SANDY’s destruction, checking for underwater debris and shoaling that may pose a risk to navigation. Tasked by the U.S. Coast Guard Captains of the Port, NOAA vessels can use multibeam echo sounders or side scan sonar, as conditions warrant, to search for the answers that speed resumption of shipping and other vessel movements.

As of noon today:

NOAA Ship Thomas Jefferson started out this morning for New York Harbor, where they will survey for obstructions in waterways, starting at daybreak tomorrow. Visual reconnaissance indicates debris and missing containers may pose a danger to shipping.

Navigation Response Team 5 mobilized from Connecticut and got underway in New York at first light this morning, surveying Anchorage Channel. Their next priorities are the route up to the Manhattan cruise ship terminal, Sandy Hook Channel, and then the Global Marine Terminal.

NOAA Ship Ferdinand Hassler spent yesterday and today surveying deep draft ship channels in Chesapeake Channel and Thimble Shoal Channel, as 78 large vessels, including portions of the Navy’s Atlantic Fleet, waited to transit through the entrance to Chesapeake Bay.

NOAA R/V Bay Hydro II is surveying in the Hampton Roads area yesterday and today, checking channels needed by coal shipments and aircraft carriers at Norfolk.

Navigation Response Team 2 is on its way from their regularly scheduled surveying off Florida’s coast, headed to help out in NY/NJ. Additionally, an operations manager is transporting mobile survey equipment to New York, as an additional survey resource on a vessel of opportunity.

NOAA R/V Potawaugh mobilized this morning to Lewes, Del., to survey for shoaling that may pose a risk to safe navigation for the Cape May – Lewes Ferry and other vessels. They started surveying, using their multibeam echo sounder, at 1 pm today.

NOAA Ship Rainier completes year’s surveys along Alaskan archipelago, heads home to Newport   2 comments

NOAA Ship Rainier is due to arrive at its homeport in Newport, Ore., on November 1, completing the ship’s 2012 hydrographic survey season. (Watch Rainier’s progress on NOAA’s Ship Tracker.) This survey season, Rainier departed Newport on May 17 and spent her summer mapping 604 square nautical miles of the ocean floor in Alaska, stretching from Kodiak to the Shumagin Islands, along the Alaskan archipelago.

Rainier has a long 1,769 nautical mile trip back to homeport in Newport, Oregon.

“We completed our last survey on October 24, and began the long 1,769  nautical mile trip back to Oregon,” said Rainier’s commanding officer, Cmdr. Richard Brennan. “The crew put a lot of great effort into their work, some of it under challenging weather conditions.”

Rainier and her four smaller survey vessels use multibeam echo-sounders to measure the depth of the ocean along her path, collecting millions of measurements. More than half of the area surveyed by Rainier this summer had never been surveyed before, leaving large sections of nautical charts void of ocean depth measurements. Commercial shippers, passenger vessels, and fishing fleets need updated charts, which NOAA’s Office of Coast Survey will produce with the multibeam’s precise and accurate measurements.

“Simply put, we have better maps of the moon than of our oceans,” said Rear Adm. Gerd Glang, director of Coast Survey. “Much of our knowledge of U.S. coastal seafloors dates from eras when ocean commerce was more limited, especially in Alaska.”

“At a time when Alaskan waterways are facing unprecedented demands from maritime commerce, Rainier is acquiring the data for navigational charts that are the foundation of the marine transportation system,” Glang explained.

The 231-foot Rainier, one of the most modern and productive hydrographic survey platforms of its type in the world, is named for Mount Rainier, a massive volcanic cone rising 14,410 feet above sea level in Washington. At the time the ship was commissioned, in 1968, vessels of this class were named for geological features. Rainier underwent a major repair period from Nov. 2009 to Jan. 2011, when new systems and equipment were installed.

The ship’s sophisticated seafloor mapping systems allow researchers to acquire hydrographic data that is used to update the nation’s nautical charts. Rainier carries four survey launches that survey shallow, near-shore waters.

Rainier’s scientists, survey technicians, NOAA Corps officers, and crew bring a wide range of navigational and hydrographical expertise to the mission. Rainier has a total complement of 52 people: 12 NOAA Corps commissioned officers, 11 engineers, 14 deck/boatswains, 9 hydrographic survey technicians (in addition to the officers, who are all hydrographers), four stewards, and two electronic technicians.

The ship is part of NOAA’s fleet of research and survey ships operated by NOAA’s Office of Marine and Aviation Operations.

One of Rainier’s projects for 2012 was four surveys in the Shumagin Islands, constituting 2083.2 linear nautical miles of survey lines, and 112.85 square nautical miles of seafloor – most which were never surveyed before.

NOAA Ship Hassler starts post-SANDY survey of deep draft routes to Hampton Roads and Baltimore   1 comment

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.

Lt. Cmdr. Ben Evans, Hassler’s commanding officer, got the ship underway today (Tuesday), and will return Wednesday evening. The Coast Guard Captain of the Port for Hampton Roads requested that the ship survey critical portions of Thimble Shoal Channel and Chesapeake Channel, the deep draft routes to the ports of Hampton Roads and Baltimore.

“Surveying the deepest draft channels will allow the Coast Guard to decide when to re-open the port to unrestricted traffic without unnecessary delay,” Evans explained. “The ports of the Chesapeake Bay are critical to the U.S. economy and national security, so we need to make this effort as soon as the ship is ready to sail.”

The need for hydrographic surveying is critical. There are 78 large vessels, including portions of the Navy’s Atlantic Fleet, waiting to transit through the entrance to Chesapeake Bay.

The Hassler was also a pivotal survey asset last year, as Hampton Roads resumed operations after Hurricane Irene. At that time, Hassler was one of the three NOAA survey vessels used to clear the port from dangers caused by underwater debris or shoaling. Their work enabled a rapid resumption of shipping and port operations in 2011.

“Delays in shipping, even minor ones, cost the economy millions each year,” explained Rear Admiral Gerd Glang, director of NOAA’s Office of Coast Survey. “After Hurricane Irene last year, NOAA’s rapid maritime response paid dividends in the Hampton Roads area of Virginia, where an average of $5 million worth of cargo is shipped in or out, every hour. This year, rapid response is just as critical.”

The Norfolk Custom District is the country’s 9th largest in terms of the value of total imports and exports moving through the port, with nearly $55 billion in total trade in 2011.

NOAA deploys personnel and survey assets to speed resumption of shipping after Sandy – Update 29 Oct   1 comment

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’s navigation response teams provide essential information when ports need to quickly but safely re-open in the wake of Hurricane Sandy, helping to limit the nation’s exposure to significant economic losses and adverse effects on national security caused by prolonged disruptions to the maritime transportation system.

As of noon today, the graph below depicts the position of navigation response teams, survey vessels, and equipment available to search for underwater dangers to navigation and to detect dangerous shoaling that may pose an unacceptable risk to vessels.

NOAA pre-positions survey assets for SANDY maritime response   Leave a comment

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.

As of this morning, this is the position of navigation response teams, survey vessels, and equipment available to search for underwater dangers to navigation and to detect shifting seafloor bottoms. Coast Survey’s Navigation Services Division is putting out orders now to move some of these assets, as well as pre-positioning navigation managers.

The navigation response teams (NRTs), mobile integrated survey teams (MIST) that use vessels of opportunity, autonomous underwater vehicle (AUV), and Bay Hydro II are all Coast Survey response assets. Additionally, NOAA Ship Thomas Jefferson is surveying in Long Island Sound and will be deployed if she is needed. (Update 10/28: Bay Hydro II moved from Solomons to Norfolk.)
