Lower Granite Dam

AUS performed dive support services on the Fishway Closure Project at Lower Granite Dam.

Tasks included concrete removal using a hydraulic wall saw and the installation of 3 dewatering bulkheads.

Work was performed Jan/Feb 2018.  See previous post from this site.

Ivar’s Acres Of Clams

Associated Underwater Services is working for Pacific Pile and Marine under Pier 54, Ivar’s Acre of Clams, Seattle Washington. The work consists of dredging to cut existing timber piles, designated for replacement, one foot below mud-line. The timber piles are being replaced with telescopic steel piles.

South Fork Intake Bulkhead Installation

The South Fork Reservoir is located outside Elko Nevada. AUS was contracted to install two dewatering bulkheads on the intake structure located in the bottom of the reservoir to allow repairs on the guardian gates. AUS lifted and installed two each 10,000 pound bulkheads at an altitude of 5300 feet and successfully dewatered the intake structure. Upon completion the intakes will be flooded and the bulkheads lifted back into their stored position.

NOAA Installs System to Improve Safety and Efficiency of Ships along the Cherry Point Reach in Washington State

Ship captains and pleasure boaters can now get free real-time information on water and weather conditions for Cherry Point, Wash., from a newly installed NOAA ocean observing system that makes piloting a ship safer and more efficient.

The NOAA Physical Oceanographic Real-Time System (PORTS®) at Cherry Point provides observations of tides, currents, water and air temperature, barometric pressure and winds. Collected from a variety of sensors in and around the port, the data is available online and by phone: 888-817-7794 (toll-free).

“NOAA is committed to providing quality tools and services like PORTS® which support the nation’s maritime economy,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator. “Roughly two-thirds of all the goods we buy in the U.S. arrive by ship, contributing millions of jobs and roughly $1 trillion annually to the national economy.”

Administered by the NOAA Center for Operational Oceanographic Products and Services, PORTS® can significantly reduce the risk of vessel groundings and increase the amount of cargo moved through the port by enabling mariners to safely utilize dredged channel depths. The system also allows large ships to time their arrivals and departures more efficiently.

The BP Cherry Point Refinery, the largest petroleum refinery in Washington state, partnered with NOAA to install the PORTS® sensors and communications systems. The Cherry Point Refinery is a major producer of transportation fuels on the West Coast and the Cherry Point area is also home to a variety of other marine-dependent commercial entities including a second oil refinery, an aluminum smelter, a liquefied natural gas storage and transfer facility, and a proposed bulk shipping terminal.

“The availability of real-time, accurate PORTS® data at Cherry Point will help our dock operations personnel and all the vessels that call at Cherry Point to make the best decisions possible regarding docking and cargo transfer safety,” said Scott McCreery, environmental manager for marine issues at the BP Cherry Point Refinery. “In the event of an oil spill, the data will also be very helpful in predicting the movement of oil on the water, increasing our ability to respond quickly and effectively.”

The system will also be used as a means of providing a public service to the local maritime community, making valuable environmental data available to recreational and small commercial vessels in the Southeast Strait of Georgia, as well as making real-time, validated, local environmental data available to U.S. Coast Guard Station Bellingham and U.S. Coast Guard Sector Seattle to assist in their marine safety and vessel traffic management missions.

Nineteen other PORTS® are located throughout the nation. Estimates of economic benefits attributed the system range from $7 million per year for Tampa Bay to $16 million per year for Houston-Galveston, according to studies conducted in those regions.

NOAA understands and predicts changes in the Earth’s environment—from the depths of the ocean to the surface of the sun—and conserves and manages our coastal and marine resources.

Obra-RC005-Lot3 Emisario planta RIachuela

Emisario planta RIachuela

Associated Underwater Services under contract to Impregalla Healy provided consulting design and direct supervision of the underwater concrete placement in the four drop shafts required for the implementation of the tunnel machine. Emisario planta RIachuela project came together as AUS assisted in the development of the underwater requirements including safety plan, excavation, survey, rebar and drain installation components in 165 feet of water utilizing wet divers. AUS had a direct supervisory role in placing 2800 cubic meters of concrete in 4 shafts using a floating concrete tremi system referred to as the DOBBER system. During the two-month period of work, AUS personnel that remained on-site, ensure a safe and competent placement of underwater components.
