Hermosa Beach Pier, Inspection/Repair (2010)
After cleaning the support structure of the pier, BDS divers shot underwater footage of the damaged pillars to determine what exactly needs to be fixed. As a result of what was spotted on the videos, the corroded steel that holds a large part of the pier together was immediately reinforced last week. Both steel and fiberglass "jackets" will be utilized around the damaged piling for a permanent fix to the structure. |

Municipal Pipe Inspection (2009)
A long range pipe inspection operation with 6,000 ft runs, minimal ingress, made BDS the right call for this Municipality. On site technicians inspected 40,000’ of pipe in nine days with zero downtime. Live video is recorded to DVD for immediate use by city engineers to develop repair plans. BDS utilizes an assortment of pipe inspection crawlers as few jobs are ever standard. |

Marston Reservoir - Speece Cone Installation (2008)
Our team was hired as a subcontractor to install a Speece Cone in Marston Reservoir. Project consisted of underwater diver assisted dredging to precise elevations, placement of a multi tiered rock base, underwater forming and placement of a concrete slab with rebar, heavy lift and placement of the Speece Cone and all ancillary piping onto the underwater slab. We also fused and installed 1500 feet of HDPE Oxygen line and 1500 feet of electrical cable from the beach to the
underwater Speece cone. |

Cheesman Dam (2008)
Mixed gas diving gear, multiple hyperbaric chambers, barges, multiple cranes and other equipment were mobilized to a remote, high mountain lake in Colorado. The work scope included cutting away a domed trash rack, salvaging a 115 year old intake valve (35,000lb) for placement in a museum, performing underwater steel burning and concrete removal (hydraulic breaking and 40000 psi water blasting), ROV assisted hydrographic surveys, internal ROV inspection of
the intake tunnel system with ultra-accurate sonar dimensioning, three dimensional imaging of the tunnel systems, ROV inspection of trash racks and additional work.
All of this work was completed in 180 feet of water at 7000 feet of altitude. This is a perfect example of utilizing traditional diving methods and highly technical underwater robotics systems to accomplish complex underwater tasks in a safe and efficient manner. |

King County Deep Water Outfall (2007)
Mixed gas diving gear, multiple hyperbaric systems and other equipment was mobilized to perform work at three King County outfalls, Carkeek, Richmond Beach and Alki. Ballard Diving & Salvage Inspection class ROV was used to locate the outfalls with sonar saving valuable diver time. The ROV attached down lines to the ROV and divers performed the work. |
