Operation Taconite

Posted by: LTJG Stephanie Young

When we last checked in with Coast Guard Cutter Mobile Bay they were working day and night to finish up the largest buoy retrieval operation in the nation. There is no rest for the weary though, as Mobile Bay and her crew have made the transition to breaking ice on the St. Mary’s River.

As part of Operation Taconite – a name that is derived from one of the lake’s chief commodities, taconite – Mobile Bay is taking part in the largest domestic icebreaking operation in the United States. Keeping these waterways open is crucial to the transportation of vast amounts of iron ore, needed to meet the demands of steel mills in Lake Erie and Lake Michigan.

On a typical day, Mobile Bay will break ice from sunrise to sunset. While some of their ice breaking duties are scheduled as they maintain winter shipping lanes, the ice breaking can also become a response to escort or assist vessels that are beset in the ice – a risky operation that requires skill and finesse.

“Direct assistance is by far the most dangerous, as it usually requires close-aboard, high-speed passes of vessels that can be more than 1,000 feet in length,” said Lt. Bryan Estell, Mobile Bay’s executive officer. “During these evolutions, the conning officers must be constantly mindful of the weakened ice around the stuck vessel.”

After completing a day of breaking ice, pulling into port is a luxury often denied to the cutter’s crew who more often stay on the river and remain aboard the cutter overnight by finding a portion of strong plate ice away from the established track – a practice known as being “hove to.”

Anyone who has served on an icebreaker quickly learns there is nothing routine about this mission. Crews out on the Great Lakes system know all too well how quickly Mother Nature can affect their work. This past December Mobile Bay was caught in a winter storm and can testify how quickly “ops normal” can become a response.

“We had just anchored in the lower St. Mary’s River before gale force winds, white-out conditions, and bitter cold hit the area,” said Estell. “After the storm subsided, Mobile Bay found itself surrounded by no less than 17 ships that had waited out the storm and were awaiting our assistance to head up the river.”

Weathering winter storms, cutting through ice and maneuvering close to vessels is all in a days work for ice breaking tugs like Mobile Bay. With fellow icebreakers Mackinaw, Katmai Bay, and Biscayne Bay to keep the St. Mary’s River open for commerce, Mobile Bay is in good company, and the Great Lakes communities can be rest assured that Operation Taconite is in full force.

The last of the fall buoy runs

For nine weeks, Coast Guard units across the Great Lakes have been working around the clock in the largest domestic aids to navigation recovery operation in the United States … and just in time! With the slow-moving snowstorm that brought snow and fierce winds to the upper Midwest last week, there is no doubt that winter is here and more icy weather is on the way.

Operation Fall Retrieve put Aids to Navigation teams, buoy tenders, and stations to the test as they worked together to ensure 1,264 navigational aids along 6,700 miles of Great Lakes coastline were replaced before they could become damaged by the harsh winter weather.

Units are still hard at work, braving the cold weather to finish clearing the critical aids before the ice sets in permanently. One of the units finishing up the last of the buoy retrievals is Coast Guard Cutter Mobile Bay.

Mobile Bay began the cutter’s “buoy run” in mid-October, and has primarily operated in the waters of Green Bay with an occasional trip to work on a few buoys on the Lake Michigan side of Door Peninsula.

During their run, Mobile Bay was responsible for as many as 61 seasonal buoys. A huge order for such a short deployment considering this is two thirds of all the buoys the cutter maintains annually.

The crew of Mobile Bay replaced the seasonal buoys with winter aids capable of withstanding the abuse of almost five months of shifting ice flows.

“In general, the seasonal buoys are replaced in succession based upon their importance to navigation for major shipping and to a lesser degree with the greater probability of ice forming in that location,” said LT Bryan Estell, executive officer of Mobile Bay.

While the crew still works through foul weather, like the snowstorm last week, they try to take advantage when the weather is just right for operations, which may mean working long hours over holidays to ensure the buoys are recovered prior to ice formation.

“It’s hard, dirty work; an ‘all-hands’ evolution where everyone on the cutter plays a role in ensuring that every buoy is maintained and positioned properly,” said Estell. “Every time we work AtoN, we drive away from the buoy with a real sense of accomplishment.”

The hard work and long days make a real difference for the professional mariners who transit the Great Lakes during the treacherous winter months. Mobile Bay will return to its moorings in Sturgeon Bay, Wis., but not to rest … It’s icebreaking season!
