The dry-docking (DD) operation took several hours.  The sequence involved moving the dry-dock away from the pier and slipping in a spare barge between the dry-dock and the pier.  They sunk the dry-dock so that the floor of the dock was about 6" deeper than the steel barge.  They then floated the steel barge onto the dry-dock and raised the DD until it was just touching the bottom of the steel barge at which point the steel barge was flooded to neutral buoyancy.  Next, they slowly sunk the entire thing until the concrete float was sitting about 6" deeper than it was expected to float.  

Once this was complete, they blasted air under the concrete float and it lifted free.  free of the barge, the concrete float was towed away (back to Richmond) while the shipyard began the long slow process of raising, dewatering the cleaning up the steel barge.

Ghirardelli Associates provided inspection services on the emergency repair of soffits and beams underneath Pier 33 for the Port of San Francisco. Over the years, the salt water environment had severely deteriorated portions of the structure and the repair consisted of chipping away bad concrete and installing additional rebar, silica-fume shotcrete and an acrylic elastomeric waterproof coating.
