Removal and Disposal of the F/V Tasu

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.

Olive Ranch Valve Replacement

We were hired to perform a 12″ valve replacement located in a briney pond at an olive ranch. The first task was to remove a trash screen so that one of our divers could entered a vault,burn off 12 bolts,and replace an existing 12″ slide gate valves with a blind flange until the new valve could arrive.

Upon delivery the two new valves,the dive crew will return,take off the blind flange and replace it with a new valve. In addition,a second old valve will be removed and replaced.

Alaska Bridge Inspections

Our divers traveled throughout Southeast Alaska performing underwater inspections on marine and fresh water structures. Divers inspected for timber decay,missing sections of the structures,scour,and any damage.

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.

M/V Nanuq Inspection

Vessel had problems with overheating. Problem was determined to be obstructed piping in the cooling system. Divers accessed the intake piping inside of 2 sea chests to allow for cleaning the pipe interior of obstruction.

Tanana Bridge #505

Pier 2 of the Tanana Bridge near Tok Alaska,divers installed I-Beam whalers to reinforce the existing cofferdam structure from collapse during removal. The sheet pile walls were exposed down to 12 feet below mudline where they were cut off using underwater cutting equipment.

On Pier 3 divers cut the sheet pile at mudline,then drilled 56 1 1/2″ holes into concrete debris. Explosive charges were installed in each hole.

Conditions on the work site were made all the more difficult by temperatures that ranged from -20 to 38 degrees.

Kvichak River Cable Crossing

A four man dive team was provided to Ledcor Technologies Services,to assist in pulling a messenger line under the ice across the Kvichak River,in Igiugig AK. Holes were cut in the ice across the river and strobe lights were inserted into holes marking the cable path for the diver. Once cable pull was made the diver completed a video inspection of the laid cable.

The location of the project was in a very remote area of Alaska,equipment and personnel were brought onto the site via helicopter from a camp in Igiugig,30 miles away.

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.

Stanislaus Intake Repair

Global Diving & Salvage is providing a dive crew to perform maintenance inspection and cleaning of the existing intake structure. Work also involves the removal of an existing trashrack and replacement with new. Due to limitations of access,new trashrack will be brought to site via helicopter as well as removal of the existing damaged unit.

WSU Richland Intake Inspection

Global Diving & Salvage,Inc. performed an underwater video inspection and cleaning on the water intakes at the Columbia River,WSU facility,in Richland,WA. The purpose of the dive was to inspect and clean the intake screens along with removing any extraneous debris present. Dive operations were conducted from a truck dive station,and the diver was working in water depths of 10-12ft with a visibility of approximately 10ft.
