Ballast water is essential for large vessel operations, but it is a primary cause of the spread of invasive aquatic species around the world. Harmful aquatic species and pathogens can survive a long transit and quickly multiply into pest proportions when released outside their native habitat. Organizations and governments worldwide, including the US Coast Guard …

Global’s Marine Services Division provided breasting barges and security boom to support to arrival of the US Navy ships that took part in the Sea Fair celebration in Seattle. Sectional barges sections were deployed into the water,yokohama fenders affixed to the barge and the barges were secured to the pier piling to fend the Navy ships from the pier. Once at berth,the ships were surrounded with a ‘security’ boom to prevent water craft from coming alongside the vessel.
Global Diving & Salvage,Inc. was contracted by the Alameda County Water District to install and maintain emergency pumps as a work around after a culvert collapse in the Quarry Lakes in Freemont,CA. The lakes were originally gravel quarries’ whose yield was used during the building of western portion of the Intercontinental Railroad. After quarrying activities came to an end,the lakes began to be used for groundwater recharge by the Alameda County Water District,which diverts water using an inflatable weir from Alameda Creek into the pits. As the drought worsens in California,the need for this water becomes ever more critical. Ten inch submersible pumps were connected to 12″ piping which is routed over the levy wall and into the second lake and that feeds the remaining lakes through their individual culverts. In total,nine submersible pumps were craned into position and over 2,520 feet of the piping was installed in just five days.
On June 23rd a vessel caught fire in the Des Moines Marina injuring two people. The fire spread quickly,destroying 6 boats and damaging several others. Quick action by the marina staff and fire department prevented further damage.
Global has been contracted to provide diving services as required to remove sunken boats and debris. Crew from our Environmental Response Division also cleaned areas of the boat house that were undamaged and removed sections of the dock and roof structure that had been destroyed by the fire.
Global mobilized salvage gear,an excavator,bulldozer,and waste bins to the site. A containment pit was dug in the sand upland from the wreck,and lined with 60 mil HDPE,and was then backfilled with sand. Sections of the boat will be pulled up into the containment pit to prevent pollutants from leaking into the sand beneath the liner. After the vessel has been demolished and transported for disposal,the beach will be cleaned,including any contaminated sand on the liner,and the liner will be removed. The beach will be graded back to its pre-existing condition prior to demolition.
Global supplied divers to hand operate suction dredge hose for the removal of accumulated river sediment from cooling water intakes at the mothballed N Reactor on the Hanford Nuclear Reservation.
We were hired by Florida Ship Supply to provide services for all United States Navy Ships attending the 2011 Seafair in Seattle,WA. Services included 24hr emergency spill response,fender installation,and installation of oil containment boom around all Navy vessels.
We were hired by Florida Ship Supply for the 117th Regatta in Astoria,OR to provide fenders and oil spill boom for the US Navy vessel that arrived in support of the event.
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.
A Global Diving & Salvage environmental team stands by aboard the support vessel “Faith Nicole” at a refinery near San Francisco Bay during an oil transfer between a ship and the shore-side facility. Our crew onboard the “Faith Nicole” is responsible for deploying oil containment boom from the pier in the event of a spill during the transfer.
