PCSD Reliance Refloat

The recent sinking and recovery of the Pierce County Sheriff boat Reliance brought not only a vessel to the surface,but also demonstrated outstanding leadership. From early on,Sergeant Jake Greger of the Sheriff’s Department served as an instrumental point person. His coordination and direction of the Sheriff’s Department personnel played a critical role in ensuring the recovery of the vessel went smoothly and ithout incident. His communication of events enabled the entire Sheriff’s Department personnel to act and assist as needed.

As is often the case,outside agencies and private industry were also a part of the recovery operation. Special thanks is given to Doug Stolz,a specialist on the Washington State Department of Ecology’s Spill Response team. Given the over 150 gallons of fuel and oil on the vessel,his input and guidance were invaluable in helping protect the environment in what could have potentially been a harmful mess. Credit also must be given to the Tacoma Police Department and the Tacoma Fire Department for their assistance in providing containment booms as well as the Seattle-based Coast Guard crew for their oversight and direction in protecting against ecological risks.

Genes Towing worked diligently with Sheriff’s dive team members in providing any equipment and service requested throughout the recovery process. Randy Baron,dive operations manager for Global Diving and Salvage,Inc,expertly directed his crew in the ultimate recovery of the vessel. Their expertise ensured that the vessel was not only raised safely,but also without any significant leaking of contaminants.

Beachwalk WWPS decompression chamber

Global Diving & Salvage,Inc.is providing Hyperbaric Consulting Services,including assistance with drafting of Hyperbaric Intervention Plan of the Beachwalk WWPS project in Honolulu,Hawaii. Global has also assisted with the design,procurement,and modification of a decompression chamber that will be used in the event that a hyperbaric intervention becomes necessary during the digging of the force main portion of the project. The new tunnel,7 feet in diameter will be bored with a micro-tunnel machine. In the event of need for hyperbaric intervention,a bulkhead will be installed near the opening of the tunnel,the decompression chamber will be mated to the bulkhead and the compressed air workers will enter the tunnel through the decompression chamber. They will decompress on the way out,if needed. Global will provide supervision of the hyperbaric events.

Derelict Vessel Removal

Crews raised a heavy 38 ft wooden vessel using lift bags. The vessel was then patched and pumped for delivery to a demolition site per client instructions.

T-18 North Harbor Island Mooring Dolphins

Provided on-call dive support for the removal of four dilapidated timber mooring dolphins. Divers also assisted with the installation of steel dolphin replacement structures,including the installation of new structural steel members underwater. The installations included welding anodes onto the dolphins and securing plastic fenders.

Finley Pump Station Sediment Removal

Approximately twelve (12) feet of sediment has built up in front of intake structure of the Agrium Finley Pump Station located on the Columbia River in Kennewick,WA. Divers used a suction pump to pump the sediment / water slurry from the forebay area to an upland location for disposal. Divers operated from a dive trailer located on shore adjacent to forebay area. The suction pump was located on the adjacent pump deck; a booster pump was in line to assist in moving the sediment / water slurry the long distance to the disposal location.

Caisson Drydocking

Global Diving & Salvage provided two dive teams working from small DSV’s to assist with the drydocking of a graving dock caisson. The gate had never been drydocked before; special attention had to be paid to layout of blocking and installation of shims.

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.

Ocean Outfall Repair

Global Diving was contracted by Netarts Oceanside Sanitary District to replace a broken elbow on the existing ocean outfall offshore of Netarts,OR. A local fishing vessel from Garibaldi was used as the dive platform. Diving was carried out using Nitrox to increase the available bottom time of the divers. Per OSHA rules a deck decompression chamber was set on the back deck of the fishing vessel.

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.”

Hiram M. Chittenden Locks – Emergency Scour Inspection

A recent inspection dive performed by US Army Divers identified a large area of scour on the outer wall,Global installed permanent points on the wall to base measurements. Reference points will enable future measurements to be made identifying additional scour. A hand held sonar was also used to create a visual image of the scour.
