Historical Tug USS Wenonah
October , 2009
We were contracted by the US Coast Guard – Sector San Francisco and quickly dispatched a team from our office in Rio Vista, CA. Salvage specialists, divers and heavy rigging equipment arrived at the scene while naval architects calculated weights and analyzed the vessels strengths and lifting characteristics.
Working in 30 feet of water, our divers dug trenches in the thick mud and debris beneath the wreck and maneuvered heavy chains underneath it in preparation for lifting. We contracted with American Bridge/Fluor to acquire the services of the “Left Coast Lifter,” a shear-leg crane working in San Francisco Bay, to assist in re-floating the vessel. With a lifting capacity of 1,700 metric tons, the “Left Coast Lifter” is one of the largest floating cranes operating in the continental United States.
On August 31, with the vessel back in her berth and safely afloat, we delivered the vessel to the US Coast Guard – Sector San Francisco, which is working with other agencies to determine the vessel’s future.
“Synergy between state and local agencies ensured the unified command was able to focus resources in an efficient and timely manner,” said LCDR Agustus Bannan, U.S. Coast Guard – Sector San Francisco. “Serving the general public and our stakeholders, we capitalized on the cooperation and good will of Global Diving and American Bridge that brought us the needed resource to complete the job.”
