But since the boat was sitting on the seafloor, sediment had also collected inside the vessel. In addition, the water had soaked into the boat's shag carpet, mattresses and other porous materials. The boat originally had 18 in. of free board, but with all the added weight, Global was now working with just 3 to 4 in. above water. "Those are pretty narrow margins to work with from a stability standpoint," Watson said. Results Despite it being a long and difficult haul through the busy Bay Area, Global delivered the Spirit of Sacramento to Sausalito without incident. "There's definitely a sense of accomplishment," Watson continued. "All the planning, the naval architecture, the en- gineering, and then the work the divers did—it all came to a head and it worked. That's definitely a proud moment." Before Global demobilized from the project, they were also contracted for hazardous materials abatement on the Spirit of Sacramento. The crew conducted a full sweep of the vessel, removing batteries and flushing fuel lines. "We completed the project with zero injuries or inci- dents," Watson said. "A good safety program in a warehouse that loads trucks with forklifts everyday is one thing, but having a solid safety program when you go out and do what we do is very challenging. Global has been very successful in setting the standard in our industry." ST Lara Mayer is the marketing communications coordinator for Global Diving & Salvage Inc., a worldwide leader in the marine services industry specializing in marine casualty response, subsea construction and commercial diving. She has a degree in journalism and mass communications from the University of Oklahoma. With the assistance of federal and state agencies, Global successfully parbuckled and lifted the Spirit of Sacramento from the seafloor without causing further damage. In the process, no fuel was spilled. "The boat came right up to the surface as planned," Wat- son said. "That was a big high." With that phase accomplished, the team moved on to the challenge of removing the abandoned Spirit of Sacramento from the bay. "The Bay Area really lacks a facility suited for receiving a vessel like this after it's raised," said Watson. "There are two functioning shipyards, but they are large, very expensive op- erations designed to receive 600-foot ships for repairs." Several smaller facilities in the region turned the Spirit of Sacramento down, so Global's only option was to obtain a dead-ship tow permit from the Coast Guard. That allowed crews to take the vessel 56 mi. to an Army Corps of Engi- neers dock in Sausalito, California. But, that tow came with (Top and Bottom) After being raised, the Spirit of Sacramento was towed to Sausalito. Due to the size of the vessel, a crane had to be transported from Seattle, Washington, to perform the heavy lift.
