PEMEX's PSS Chemul hit the Cochrane-Africatown USA bridge
Oil platform slams into span

A 13,000-ton oil platform blown loose from its moorings Monday morning by Hurricane Katrina plowed through a state docks terminal and then slammed into the Cochrane-Africatown USA bridge, severing a vital trucking link.
It was unclear Monday evening how long the bridge would be closed. State Transportation Department inspectors began examining the bridge Monday evening after traveling from Montgomery, but were expected to complete their work this morning.
Trucks carrying hazardous materials depend on the bridge to bypass the Wallace and Bankhead tunnels, where such cargo is prohibited. The closure means hazardous-material trucks must go north to Interstate 65 to cross the river.
Tony Harris, a transportation department spokesman, said the state was working Monday to deploy message signs warning of the detour.
The PSS Chemul, an oil platform belonging to Mexican state oil company PEMEX, had been drydocked atop a leased barge at Bender Shipbuilding & Repair Co. Inc.'s yard nine. The shipyard is on Blakeley Island, on the east bank of the Mobile River. Bender won a contract last year to expand and refit the vessel, which holds crews and does maintenance on offshore oil platforms.
Bender could not be reached for comment Monday.
Monday morning, a "very alert" captain of a nearby ship saw the loose platform and reported it, according to Harbormaster Capt. Dave Carey. Tugboats chased the Chemul, but couldn't corral it, as it blew across the river, colliding with a berth and then a barge loader at Alabama State Port Authority's Bulk Material Handling Plant.
The Coast Guard monitored the news of the Chemul, but couldn't send out crews right away because of the dangerously high winds, according to spokesman Petty Officer Nyx Cangemi.
"It really comes down to life over property," he said. Initial reports showed that the platform rolled down the berth near the mouth of Three Mile Creek, potentially hitting it several times, docks Director Jimmy Lyons said.
The rig then destroyed a barge loader. "The barge loader is gone," Lyons said.
The docks agency was spending $10 million to expand the berth, which was planned to handle wood products and general cargo. The berth was scheduled to reopen within weeks, but the collision may have damaged the dock or its pilings. Lyons said the barge loader alone was worth $4 million, and pier damage could cost millions more.
The bulk plant and barge loader were just an appetizer for the Chemul, which drifted farther north, scraping under the bridge before 11:15 a.m., according to Tony Harris, a spokesman for the Transportation Department.
The collision with the 140-foot-high bridge roadway sheared off much of the top structure of the platform. The storm-surge swollen river pinned the Chemul under the west side of the bridge for several hours. But about 5 p.m., the barge began to slowly pinwheel, as the receding river allowed it come unpinned.
Harris said inspectors planned to eyeball the $70 million bridge Monday night. Opened in 1991, it is Alabama's only cable-stayed bridge.
Pemex will be held liable for the damage to docks facilities, but that issue might be settled between Bender and Pemex, Lyons said.
When Bender landed the contract in November, the company touted it as the first oil rig job. The project was projected to employ as many as 350 people, as Bender repainted the platform, as well as adding new office and living quarters.
Although the Port of Mobile shut down Sunday night, three ships were unable to evacuate.
"The weather got too bad too fast to get them out," Lyons said.
The port could remain closed for days before the Army Corps of Engineers and Coast Guard inspection teams find it safe to navigate.
The oil platform was not the only escapee during Katrina. Robert Rishel, vice president of towboat company Henry Marine Services, said tugboats chased a number of barges. "The tugboats did what they could," Rishel said.
Rishel drove to the end of Paper Mill Road Monday evening to look at the oil platform, and spotted what appeared to be several barges floating over the CSX railroad track north of the bridge.
Docks officials received preliminary reports of empty containers floating loose after the container yard flooded, they said. The police building lost shingles, a maintenance building lost a roof and some of the warehouses lost doors. That could mean damage to the forest products like lumber, paper and plywood, Lyons said.
The Alabama state docks was one of the first areas to flood Monday, and Harbormaster Carey estimated the storm surge to be 11 feet.
