Skagit River Bridge Collapse

On Thursday,May 23,2013 while traveling on the southbound lane of Interstate 5,a truck hauling a heavy and oversized load struck the support structure of a bridge crossing the Skagit River in Mt. Vernon,WA. The damage inflicted by the truck caused the 160 foot long four lane span to collapse into the river below,completely severing the north and south bound lanes of the major west coast interstate highway.

Global Diving & Salvage,Inc.,under contract to Atkinson Construction,worked around the clock for 13 days under direction of the Washington Department of Transportation and the National Transportation Safety Board (NTSB) to provide diving and salvage services throughout the investigation and debris recovery phase of the project.

Dive operations in the river were complicated by high river currents resulting from spring runoff conditions. The salvage operations included a detailed underwater survey of the downstream edge of the wreckage to ensure that it was safe to bring demolition equipment alongside. Motor vehicles caught up in the collapse were recovered. Working closely with the NTSB the bridge wreckage was cut and rigged out of the river. With the river cleared of debris,an underwater inspection of the concrete bridge piers was performed in order to confirm the structure remained viable for bridge reconstruction.

Refloating the Tug Tiger

The United States Coast Guard tugboat Tiger sank at her mooring at the Richmond Historical Pier in California. Global responded with 4 boats,2 skimmers,boom,and spill response materials to contain and remove the released containments.

Global was contracted to continue the salvage operations,utilizing an innovative plywood freeboard panel concept in an effort to refloat the Tiger.

Crescent City – Tsunami Response

On March 11th,2011 after the 8.9 magnitude earthquake in Japan a tsunami wave crossed the Pacific Ocean landing squarely in Crescent City,California. Our crews were activated by the US Coast Guard to provide environmental and diving services necessary to address the immediate pollution threat caused by the tsunami,which damaged 30 vessels in the Crescent City Inner Harbor on the coast of Northern California.

Our initial response was directed to contain fuel which had already leaked from the various vessels,as well as to prevent fuels and oils on-board from further release. The initial dive tasks focused on surveying the wreckage and addressing the pollutants. During the survey,it was observed that several of the sunken wrecks were piled on top of each other,making it unsafe for divers to access points of release and fully seal leaks. Divers were able to seal exposed ports and remove fuel from the tanks of vessels they could access.

To safely remove the unstable vessels a derrick barge was brought in from San Francisco. Divers used straps and slings to rig the larger,more intact sunken wrecks to lift them from the water A clam bucket was used grip the smaller and more severely damaged vessels. All wrecks were transported to shore for proper upland disposal.

In all 10 sunken vessels were removed from the Inner Harbor. Over 400 gallons of fuel and oily waste were contained and properly disposed of.

M/Y SCOUT Salvage

The M/Y SCOUT suffered catastrophic flooding and was abandoned near the entrance to the Straits of Juan De Fuca. Global Diving & Salvage was engaged to recover and salvage the wreck. After extensive air and surface searching by USCG assets the wreck was located by a passing fishing vessel at 48 28.9N,124 41.8W,in the middle of the shipping lanes,2.5 miles ESE of the JA buoy. Utilizing the Neah Bay based rescue tug JEFFREY FOSS Global towed the vessel into Neah Bay,WA where she was successfully patched and refloated with the assistance of a Bergerson Construction derrick. Diesel fuel oil and other HAZMAT were removed.

Boat Explosion Response

Global mobilized a rapid response team to the Jim Clark Marina Explosion after one of the resident boats blew up in the early hours of August 24th,2010. The exploding boat caused the complete destruction of it’s boat house and damaged three other boat houses including catching an adjoining boat and boat house on fire. Our crew’s initial response consisted of surveying the damage and deploying boom to prevent any debris or contamination from leaving the accident site. Global’s Dive Operations Mgr says “We were chosen as a full service emergency response provider due to our conveniently poised response equipment,our knowledgeable personnel,and our prior work experiences.”

Deepwater Horizon Spill Response

Provided shoreline clean-up services to the Gulf of Mexico oil spill clean-up effort following the explosion and fire aboard Transocean’s Deepwater Horizon drilling rig on Tuesday 20 April at approximately 10:00 pm US central time. Our crews were initially stationed in Pascagoula,MS before being relocated to Cocodrie,LA in an effort to protect the state’s barrier islands .

A Unified Command was established to manage response operations.

Angel Rae Salvage

A live-aboard vessel sank at it moorage on the Duwamish River. Global Diving was contracted by Department of Ecology to mitigate any potential fuel release as well as raise the vessel and remove it from the water. Containment boom was deployed around the vessel as well as various locations around marina to mitigate the spread of fuel in the river current. The fuel vents and caps were sealed. Lifting straps were run under the vessel. A derrick was brought to the site to lift the vessel off bottom. Once on the surface,water was pumped from the hull.
