Campbell Shipyard Receives a Massive Underwater Geosynthetic Sediment Cap Adjacent to San Diego Hilton Convention Center
A site known as Campbell Shipyard adjacent to the Hilton San Diego Convention Center in Downtown San Diego, California has been used for over 100 years for industrial activities that included commercial fishing ships and naval ship repair early on and eventually moved to a petroleum tank farm, municipal refuse incinerator and gas manufacturing and waste facility. In the 1990s, the shipyard lease expired and a massive cleanup of the site soon began. After many years, the port completed cleanup of the above water portions of the site, but found it too expensive to test and safely remove all of the 37,000 SM (9.2 acres) of polluted sediments hidden below the water's surface on the bay floor. Engineers decided to create a massive underwater permanent cap over the contaminated soils. At the heart of this mammoth size underwater cap is a high strength woven geotextile panel that was created with a unique blend of both polypropylene and polyester fibers (to yield a specific gravity greater than water) that sinks. The geotextile rolls were sewn into massive panels and fitted with PVC encased rebar that were deployed directly from a moving sectional barge using GPS tracking to assure proper over-lap and location of adjacent panels.
