 CORPUS CHRISTI, Texas AP - The bodies of two missing crew members of a dredging boat were found Saturday following an explosion a day earlier in the Port of Corpus Christi in Texas, according to the U.S. Coast Guard. Two other crew members of the dredging vessel Waymon L Boyd remain missing and the search for them continues, Coast Guard Capt. Jason Gunning said during a Saturday afternoon news conference. The explosion happened at about 8 a.m. Friday when the vessel struck a submerged pipeline, according to the Coast Guard, and Port of Corpus Christi officials said it was a natural gas pipeline.

The Waymon L Boyd is owned by Houston-based marine construction contractor Orion Marine Group. We greatly appreciate the efforts of the U.S. Coast Guard and other responders in their efforts to recover our missing crewmen, Orion CEO Mark Stauffer said in the statement. The fire onboard the vessel was first extinguished Friday afternoon, but sparked again and was finally put out at approximately 10 p.m. Friday, shortly before the vessel broke apart and sunk, the Coast Guard said. The vessel carried a maximum of about 6,000 gallons of diesel fuel, said Brent Koza, the regional manager for the Texas General Land Office, which investigates oil spills. We have identified and are preparing for that as our worst case discharge scenario, and diesel is being recovered from the channel...
