Dennis fixes problem with largest ship sunk as artificial reef
The Associated Press
July 11. 2005 11:03PM
In the wake of Hurricane Dennis, a miscue with the largest intentionally sunk ship in the world was found Monday to have been put right.
The former USS Spiegel Grove, now serving as artificial reef on the bottom in 130 feet of water off Key Largo, flipped upright as the core of the storm passed well over 200 miles to the west.
It's a position project organizers wanted since the retired 510-foot Landing Ship Dock prematurely sank and rolled over May 17, 2002, leaving its upside-down bow protruding from the water.
Three weeks later, a salvage team managed to fully sink the vessel, but on its right side instead of its keel. Three years later, the Spiegel Grove is the most popular artificial wreck in the Florida Keys, home at least 166 different fish species, said Lad Akins of the Reef Environmental Education Foundation.
"I'm flabbergasted," Rob Bleser, volunteer project director, said Monday afternoon after a dive on the newly oriented Spiegel Grove. "Nature took its course and put it where it belongs."
"This will mean a whole new dive for those that have dove it before," Bleser said. Its highest point is now 60 feet down.
Words of delight about the Spiegel Grove moved quickly through the Florida Keys' sport dive industry, but at least one federal official was not happy.
"It's bad news from my perspective as a resource manager that it moved," said Billy Causey, the Florida Keys National Marine Sanctuary Superintendent. "We have to figure out why."
Matt Strahan, meteorologist in charge at the National Weather Service Office in Key West, said waves at the wreck were as high as 20 feet Friday afternoon, when Dennis was southeast of Cuba.
"Waves that high in close proximity to the reef can produce unusually strong currents with tremendous force," Strahan said.
The Spiegel Grove reef is about six miles off Key Largo. Bleser says there have been about 75,000 sport dives on the wreck since it opened.
The ship, designed to carry cargo and craft for amphibious landings, was retired by the Navy in 1989.
Causey said sanctuary officials will temporarily close the wrecksite to sport divers to analyze its stability and replace lost mooring buoys.

Apparently, Billy doesn't realize that waves carry energy, which then has to be dissipated, converting into power and work performed en route.
Using this web resource...
http://www.coastal.udel.edu/faculty/rad/wavetheory.html
...and plugging in 7m (for 20ft wave height), 33m depth (swag) and a wave period of 5 seconds, it predicts the wave energy at roughly 60,000 N-m/m^2 (unit conversion: 60 kilo-Joules/m^2)
The above model predicts that the wave would be ~39m long, and assuming a 20m width to be very roughly the fraction that would act upon the hull, this would be ~800 m^2 of wave.
60 kJ/m^2 * 800 m^2/wave * 1 wave/5 sec = 9,600 kJ/sec = 9.6 MW.
Ten megawatts of power isn't a terribly huge amount, except when its concentrated onto one object (the Spiegel Grove), where it will tend to get its attention.

I considered commenting on that. It doesn't take a rocket scientist (or engineer) to figure out that it moved because the waves moved it.
I also find it interesting that, from the perspective of a resource manager, he dinds it a problem. I guarantee that the Spiegel Grove, upright, will be a better dive than it ever was on its side.
Curtis, Popeye, Dave, Mike, Bullshark, whoever else, up for a trip to Key Largo? We need to schedule it after the effect of Dennis on visibility has diminished but before Emily knocks the damned boat back over on its side.

I was supposed to be in Key Largo right now, but had to cancel my trip. I can't wait to dive the Grove again, but I also wonder how long it will stay upright. I would think it would be harder to tip over again now, as it no longer offers the same profile to the oncoming wave energy, but my first thought was that with the hurricane season that's been predicted, the Grove could end up being a shore dive by September!
And remember that this incident happened when the actual hurricane was many miles away over Cuba.
Nevertheless, please reserve my spot!

Hmmm, you've got an odd number and could use one more to protect against the dreaded "assigned buddy." I can't make it on Thursday, but I might be able to dive on Friday. I think I may even have the right mix in my 100's. When do you plan to dive the Grove and who do you plan on using? Any word of visibility? The strong winds of the last few days have got to have had some negative effect.

Request: Please don't dive Spiegel right now
BY STEVE GIBBS
Citizen Staff
KEY LARGO - The mooring buoys from the Spiegel Grove artificial reef were removed Tuesday and Florida Keys National Marine Sanctuary officials called for a voluntary closure of the wreck, while Upper Keys dive operators celebrated the uprighting of the massive sunken ship by Hurricane Dennis.
Also Tuesday, sanctuary divers discovered that another intentionally sunk ship - the Adolphus Busch off Ramrod Key - also had moved around in the storm.
A voluntary closure is faster and more flexible than going through federal regulations to officially close the site to diving, said Cheva Heck, spokeswoman for the sanctuary.
"Once we see it's safe and try to get a new assessment done, we'll re-install the mooring buoys," she said.
Heck said sanctuary divers Tuesday checked out the Adolphus Busch, a 210-foot ship sunk in 1998 three miles from Looe Key, and found the ship had listed to starboard by 5 to 10 degrees, exposing the entire keel and the propeller.
The ship's starboard bow anchor broke and the starboard stern anchor is "very, very taut," indicating strong seas from the southeast, Heck said.
Divers couldn't find the port bow anchor and the ship has settled an additional 8 to 10 feet into the seafloor, making it a deeper dive, Heck said.
Meanwhile, sanctuary divers and the dive shop owner who directed the sinking of the 510-foot Spiegel Grove descended upon the site to check out its new orientation.
The May 2002 sinking of the Spiegel Grove gained worldwide attention after the ship sank prematurely while being readied for scuttling and settled on her side. The Key Largo Chamber of Commerce and Monroe County spent $250,000 to hire a salvage company from Stuart to right the ship. But salvers could only turn her 90 degrees, and there she stayed for the past three years - until Hurricane Dennis.
"I'm flabbergasted," said Rob Bleser, the volunteer project director, after he surfaced from a dive on the newly oriented Spiegel Grove. "Nature took its course and put it where it belongs."
According to Matt Strahan, meteorologist in charge at the National Weather Service Office in Key West, the waves above the Spiegel Grove wreck site could have been has high as 20 feet Friday afternoon.
"When Dennis was southeast of Cuba, it would have produced very high waves that computer models project could have reached Key Largo," said Strahan, according to a press release from the Tourist Development Council. "Waves that high in close proximity to the reef can produce unusually strong currents with tremendous force."
The Spiegel Grove is in 130 feet of water, about six miles off Key Largo. The ship, designed to carry cargo and craft for amphibious landings, was retired by the Navy in 1989.
Bleser said the ship is still facing in an easterly direction and has not changed location.
"This will mean a whole new dive for those that have dove it before," Bleser said. "Its orientation is now less confusing for new divers, and it's a bit deeper dive now."
He estimated that the ship now sits 10 feet deeper since it rolled over into a large trough created as currents eroded the soft sand from under the ship's hull over the past three years.
"She's more stable than ever," he said. "And she's sitting as level as a pool table."
Capt. Todd Firm, who like Bleser is a dive shop owner, said the real upside of the phenomenon is the worldwide publicity the dive industry and the entire Keys receive from it.
"This is great for the dive business," said Firm, who's also a TDC board member. "With the national press picking this up - CNN is running it - it's a win-win for us and it doesn't cost any advertising dollars."
Bleser said there have been about 75,000 sport dives on the wreck since it opened to divers.
Residents have purchased more than 500 bronze medallions at $250 apiece to help support the sinking of the ship. A plaque was attached to the ship while it was on its side that lists the names of those who helped support the project. When asked about the plaque, Bleser said it is attached to the port side of the ship just below the second deck railing.
"It's on the lee side [of the current]," he said. "It looks real good."

That's good news.
I'm scheduled for a three diy dive trip to the Dry Tortugas area on August 8 and I was planning a week long vacation in Islamorada on the 12th. Unfortunately, the motel we booked with lost all their docks as Dennis passed by. I've rescheduled the same week at Crystal Bay Resort in Marathon. We'll be trailering our 15 footer down. At the end of the week, we'll be joined by a bunch of boat club members and their "dinghys." In this context, dinghy means whatever they want it to mean, from 8 foot inflatables with motors barely able to plane them out, to , well, to me and my 85 hp 15 foot V hull. If I were only coming down for the weekend, I'd bring my inflatable dinghy too. Mine, however, is 10 feet and powered by a 25 Mercury. It's downright scary.
> Big Pine Shoal Marker (36'?) destroyed. Not good. Sea Tow, on the other hand, will be pleased.

I sincerely hope they ignore the request. The operators in that area could use a break and this is probaby just the kind of break they need. I'm sure I'm not the only one that saw the Grove on its side that would love to see it as it was supposed to be, upright.
> "Once we see it's safe and try to get a new assessment done, we'll > re-install the mooring buoys," she said. What, do they think the ship's going to fall on somebody? This is more than a little silly. I guess if I want to see it soon, I'll have to take my own boat down. That's a hassel and an expense I would just as soon avoid for a day trip.
> Divers couldn't find the port bow anchor and the ship has settled an > additional 8 to 10 feet into the seafloor, making it a deeper dive, > Heck said. Ummm, there's something wrong with this statement, or the guy that said it. I guess he means that the shallowest depth that will allow you to reach the wreck is deeper. That's a pretty deceptive concept and, considering that the top of the wreck is not all that deep, not a big deal. The movement of the ship, on the other hand, is a bit of a concern.

"Waves that high in close proximity to the reef can produce > unusually strong currents with tremendous force." When Andrew hit South Miami, the Noula Express, a ship sunk at about 120 feet, well north of where hurricane force winds were, was broken in half, the stern section was lifted and put down on a smuggler's sub placed nearby and then picked up and put down near it's original location again. It sould be no surprise to anybody that hurricanes do a lot more underwater than expected.
> "This will mean a whole new dive for those that have dove it before," > Bleser said. "Its orientation is now less confusing for new divers, and > it's a bit deeper dive now." Deeper? I guess that means that the ship is wider than it is tall.
> "She's more stable than ever," he said. "And she's sitting as level as > a pool table." So what's the danger preventing operators from visiting the site?

I don't go to as many Sanctuary Advisory Council meetings as I once did but I was present on Dec 14th 2004 when the author of the article below made a presentation to the council:
http://www.palmbeachpost.com/storm/content/martin_stlucie/epaper/2004/10/16/m1c_ mcreefs_1016.html
Just talked to some divers returning from the A. Bush (Busch?) seems it took a hit too..
Steel Ibeam (marker 24) at Looe Key is not standing.
Current thinking (pun!) (radio news) is that sand scoured from underneath it made a pit and the grove rocked into to it.

Snoopyto - 12 Jul 2005 17:55 GMT Okay, I apologize to the Original poster because I thought he was paying a April Fool joke out. Sorry!!
Here is the link to Miami Hearld noting more information. http://www.miami.com/mld/miamiherald/sports/12111453.htm
This great news for the diving community. I just wonder if there is a way to secure it in position. Next storm that comes by could just undo it as well.
