Eagle`s Divers Beau Up On Storm-Damaged Casino - Broco
These Games Weren’t Rigged O n the morning of August 29, 2005, an ominous, grayishgreen wall of water smashed the coastline of Biloxi, Mississippi. Considered by the National Weather Service as one of the worst storms to hit the United States, Hurricane Katrina’s destructive swath stretched over 300 miles – from Baton Rouge, Louisiana, to Mobile, Alabama. Katrina’s storm surge was greatest along the Mississippi Gulf Coast. “We had a crane barge in Biloxi’s back bay when Katrina came ashore. From the debris on the crane’s boom, I think the surge was over 30-feet high,” says Robert Baker, General Manager of Baker Pile Driving & Site Work, (Madisonville, LA), a marine and land contractor in Mississippi and Louisiana. “Katrina threw our barges and equipment around pretty good.” Biloxi, with its thriving gaming industry, sits along the Mississippi gulf coast. In the days and weeks following the storm, people assessed the damage to their business and family lives. Individuals were asking, “How do we rebuild?” Casino owners were asking the same question. When Katrina made her unwelcome landing, many of the casinos along Mississippi’s coast sat on barges, usually a series of barges. Most of the casinos were damaged beyond repair – some even thrown onshore. But one casino was built differently from the rest. Eagle’s Divers Beau Up On Storm-Damaged Casino By Ronald Ward, Jr. The Beau Rivage The Beau Rivage casino was designed more like an oil platform – with its barges submerged underwater. On top of this structure sits the casino and a 32-story luxury hotel overlooking the Gulf of Mexico. The design allowed the storm surge to pass underneath the structure above, while the barges remained underwater. Although its unique design prevented total destruction, the immense energy created by Hurricane Katrina’s rush of water still caused extensive damage to the Beau Rivage – both above and below water. Structural beams connecting the barges to the superstructure were ripped apart. Many of the connections between the barges showed signs of cracking. To fix the underwater damage, Eagle Diving & Marine Services was called in to assist the Beau Rivage Restoration Project. A division of Baker Pile Driving & Site Work, Eagle has provided diving services since 2002. A Deadline to Meet At the outset, the Beau Rivage set the one year anniversary of Katrina, August 29, 2006, as the re-opening date. To meet the deadline, the casino categorized repairs as either critical path or maintenance. 20 www.adc-int.org • www.underwater.com July•August 2007 July•August 2007 www.adc-int.org • www.underwater.com 21 Critical path items were those areas of repair identified by the casino as structurally necessary for reopening. These included beams that were completely separated from their footing. Although maintenance items were still necessary, the casino did not require those repairs before re-opening. “The scope of this project was different because of the extent of damage,” says Baker. “The hotel and casino sustained a lot of damage both above and below the water. The topside contractor at times had hundreds of employees on-site. In order to reopen the casino, there were dozens of companies on site. Just moving people and material into place was challenging at times. I think our divers were thankful just to get into the water, and away from the commotion above.” Robert Baker, General Manager, and Mark Crowell, Eagle’s Dive Supervisor, oversaw the debris removal process. Of Welding Rods and the Critical Path In order to accomplish the task, Eagle Diving & Marine Services utilized several teams of divers. “Our dive teams inspected the damaged areas,” says Mark Crowell, the job supervisor for Eagle. “We conducted visual inspections, and followed up with magnesium particle testing, or MT tests. MT allows us to detect the extent of cracking in an area.” Once the cracks were located and evaluated, Eagle’s divers on the weld team per- 22 www.adc-int.org • www.underwater.com July•August 2007 Eagle Diving welders Chris Martin (left) and Lauren Wyman (right), sizing up the damage and stickin’ it back together. formed the repairs. Some of the structural beams were completely separated from the barge, and needed to be reattached. Eagle’s divers worked with the topside contractor to replace or repair the structural beams. Flat pieces of metal – called doublers – sit between the structural beam and the barge. Because of the peculiar makeup of the steel used on the doublers, Eagle searched for an appropriate welding rod. A 3/32-inch nickel alloy rod, developed by Broco (Rancho Cucamonga, CA), fit the bill. Following the guidance of the American Welding Society (AWS), Eagle developed welding procedures to meet the requirements of the job. For the project, Eagle qualified welding procedures in all positions required by the casino. Thomas C. West, Director of Welding Engineering Services (Lafayette, LA), served as the casino’s welding consultant. West evaluated and approved Eagle’s dive procedures. Tough Welding for the Eagle Eyes “Due to the water quality at the casino, we conducted some testing at our facility in Madisonville, in the Tchefuncte River, and created the welding procedures for the job,” says Robert W. Baker. “On good days, our welders worked with poor visibility – usually only up to six inches. Even so, the weld had to stick,” adds Mark Crowell. In order to confirm the welds, Eagle conducted ultrasonic testing (UT) on the welded areas. “UT gives us confirmation that there was full penetration of the weld,” says Crowell. Armed with Broco’s nickel alloy welding rod and accepted weld procedures, Eagle was on the task. Yet, to finish the critical path items on time, Eagle faced a new challenge – storm debris. Lots of it. Mattresses, chairs, trees, slot machines, you name it. Eagle put the debris team on the job to clear the way.

Some Rough & Tumble Ops Managers Throughout most of the project, Eagle dispatched four dive teams on the project – a debris team, an inspection team, a weld preparation team, and a weld team. Each team had four members. On many days a couple of unofficial team members – a pair of alligators – worked as observers to the project. Unfazed by the salty water of the Gulf of Mexico, the gator team found their way underneath the casino from a drainage pipe. The gators kept a keen watch over the repairs, without getting too friendly with the divers. Eagle completed its critical path items more than six weeks before the casino re-opened on the one year anniversary of Hurricane Katrina – August 29, 2006. In the months following completion of the critical path repairs, Eagle focused on maintenance repairs. Most of the maintenance repairs involved cracks to the structure and connections between Steven and Harold “Jerry” Smith wondering “Who’s gonna taste it?” July•August 2007 www.adc-int.org • www.underwater.com 27 The Eagle Diving crew (L to R): Mark Crowell, Clayton Murphrey, Chuck Blagrove, Tim Tichnell, Ben Hannon, John Higgins, Lyle Witchley, Joe Middledorf, Shawn Henry, Roy Smith, Kurt Ward, Bobby Davis, Donald Waldner, Dan Kuspit, Lauren Wyman, Houston Ennis, and Chris Martin. The inspection services provided on the project by ATC and Southern Inspection Services were crucial to Eagle’s work on the project. The coordinated efforts of these companies made this project a success. Many of us along the gulf coast see the world in a different way since Katrina. Our lives befoe the storm – affectionately called “pre-K” – was the old norm. Since Katrina, our fast-changing world has defined the new norm.

In all, Eagle’s divers put down over 3,000 inches of weld using Broco’s 3/32 nickel alloy rod. Teamwork Pays Off The underwater portion of the restoration project was successful because of the hard work and dedication of Eagle’s team members. And Eagle’s team members came from near and far – from Maine to Alaska, from Michigan to Hawaii. The divers moved into the disaster zone in order to work the project. “The devastation of the area made time deadlines even more difficult. We had only six months to complete the critical path items. But at the beginning of the job, basic supplies were hard to come by. You couldn’t just go to the store to buy even a hammer. Everything, no matter how basic, had to be trucked in,” says Crowell. 28 Chris “Jersey” Griffin asks, “How close was that gator?” www.adc-int.org • www.underwater.com July•August 2007
