Would a Titanic Disaster Happen Again
Given that the builder of the Titanic is said to have famously bragged that his amazing new ship could never be sunk, it's dangerous to argue that an accident similar the 1 that sent the famous vessel to the bottom of the sea 100 years agone could never happen again.
Simply with the centennial of the Apr 15, 1912, disaster rapidly approaching, in that location's every indication that modern science and technology in combination with a much greater sensation of seaborne hazards, make such a tragedy -- at to the lowest degree on the calibration of Titanic--extremely unlikely today.
It'south non, of grade, that icebergs are no longer dangerous to mariners. They definitely are, said Mike Hicks, an oceanographer and the chief scientist at the International Ice Patrol (IIP), an arm of the U.Southward. Coast Guard.
But since 1913, the International Ice Patrol has been responsible for monitoring the ever-changing state of icebergs in the North Atlantic -- home to many of the world'due south common cold-h2o shipping lanes -- and has, in conjunction with the Canadian Ice Service, issued a "daily iceberg analysis" meant to give ship captains the very latest data on the frozen dangers that might lie in their path.
"Nosotros have a safety tape we're very proud of," said Hicks. "Non a unmarried send that heeded our warnings has struck an iceberg."
All the same, at that place is an iceberg season every year -- generally from early Feb until at least June, if not September--and during that time, there is often danger to shipping passing through the N Atlantic. Hicks explained that each twenty-four hours during the flavour, the IIP puts out its warning, typically delineating the "iceberg limit" that ships need to avoid.
Hicks said that the warning is compiled using all reports from the Declension Guard's aircraft, also as input from oil production assets in the G Banks, and information from ships going dorsum and forth beyond the North Atlantic. Once everything has come in, the IIP uses the data to generate a computer model that predicts where icebergs are probable to exist, and for how long.
"It's basically a line on a chart of the ocean, and it shows that there'south ice within of this line, and then if you stay exterior of this line, yous should be safety," Hicks said. "If a transport is leaving Montreal and going to Germany, they'll look at the [alert] and well before they get into iceberg danger, they'll plan their route."
Although he doesn't know the exact percentage of ships that utilize the daily warnings, Hicks said that a "large majority" practice, the exception being those that are trying to accept shorter routes, or which are carrying out piece of work that forces them into unsafe water. He pointed to the case of a 2010 blow in which a ship that wasn't heeding the warning collided with a small iceberg, an blow that while non deadly, did cavern in the vessel's "bulbous bow" and force it into drydock for large-scale repairs.
On November 24, 2007, another send, the MV Explorer smashed into a submerged iceberg off the Antarctic Peninsula, causing a pigsty "the size of a fist" that concluded up forcing an evacuation and the transport's sinking. No one was killed in the accident.
Only those incidents are very rare exceptions to the rule, suggested both Hicks and Ted Scambos, the lead scientist at the University of Colorado'due south National Snowfall and Water ice Data Center. And that'south in large role because of the ongoing international efforts to monitor icebergs in crucial shipping lanes, and the work done to make certain that mariners have the latest data in their hands as they arroyo such areas.
More iceberg hazards than in 1912?
The evidence is hard to dispute: changes in the global climate are resulting in more and more icebergs shearing off in places similar Greenland, nigh certainly more than was the case a century ago.
But according to Hicks, that has nothing at all to do with dangers faced by ships making their way across the Northward Atlantic.
For example, he said, the Titanic itself had its fateful collision east of Providence, R.I., far away from the greatest preponderance of icebergs. And in that surface area, the appearance of ice depends on the currents and the collision of the dank Labrador Current and the warmer Gulf Stream, something that changes significantly from twelvemonth to year, regardless of global climate change.
Simply while there may be more icebergs breaking off of Greenland, Scambos said that almost whatsoever that made their way due south into the shipping lanes would melt well before they endangered anyone.
Nevertheless, icebergs do occur in and around the shipping lanes, particularly during the iceberg season.
As such, "nosotros meet enormous variability in the count of icebergs delivered into the shipping lanes each yr," Hicks said. "The number of icebergs we come across that affect transatlantic shipping has much more to do with complex oceanographic and meteorological process that affect the iceberg delivery system."
Radar
At the same fourth dimension, Hicks said the preponderance of ship-board radar has also made the body of water safer from rogue ice, as has the ability to get online while at bounding main in guild to await at satellite imagery.
Scambos agreed that radar and satellite Internet both play a big part in helping keep ships safe while in transit, and that while not every shipping line invests in state-of-the art equipment, nearly have what it takes to identify large icebergs.
At the aforementioned time, general understanding of oceanography is another pointer in the mariner's quiver that helps with avoiding the cold h2o currents where icebergs congregate.
Of course, radar and other technologies can only help a send helm if he or she is using it properly, and there are plenty of examples of disasters at sea resulting from incompetence.
But both Hicks and Scambos argued that with the advances in technology and the amount of effort that goes into monitoring icy hazards, ships have probably never been safer at sea, at least from Titanic-similar accidents.
"We have a much better organisation in place now than when Titanic sank," Hicks said. "But [icebergs are] still a problem. And if our organization went away, I suspect there would exist more than iceberg collisions. And a higher probability of a sinking."
