New buoys now streaming weather conditions from Port Valdez

06/24/202009/09/2019 by Amanda Johnson

Two new buoys are now in place and broadcasting weather conditions in the vicinity of the Valdez Marine Terminal.

The buoys collect weather data such as temperature, wind speed, wind direction, and barometric pressure, as well as oceanographic information like surface current direction and speed, wave heights, and water temperature. This data will help improve understanding of the meteorological and physical oceanographic environment in Port Valdez.

Terminal buoy result of cooperative partnership

The buoy closest to the terminal (pictured above) is the result of a partnership between the Council, the Prince William Sound Science Center, Alyeska Pipeline Service Company, the City of Valdez, and Valdez Fisheries Development Association.

“Partnerships like these result in collaborative science, which is the best base for providing answers to challenging questions related to planning an effective oil spill response,” said Donna Schantz, Executive Director for the Council. “The Council has long advocated for this kind of data collection at the terminal and believe the information generated will contribute to best practices for prevention and response.”

The partnership is a result of an agreement reached between the Council, the City of Valdez, Prince William Sound Aquaculture Corporation, Valdez Fisheries Development Association, Alyeska Pipeline Service Company, and the Alaska Department of Environmental Conservation regarding protections in the Valdez Marine Terminal contingency plan for two nearby areas that are particularly sensitive to spilled oil, the Solomon Gulch fish hatchery and a salt marsh known as the Valdez Duck Flats.

In 1994, the tanker Eastern Lion spilled 8,400 gallons of North Slope crude oil into Port Valdez. Oil reached the Duck Flats and hatchery before protective boom was in place.

After that spill, changes were made to the Valdez Marine Terminal contingency plan to ensure that protections were deployed quickly. A rapid-decision tool, called a “matrix,” was created to help responders assess when to deploy protective boom to the Solomon Gulch Hatchery and Valdez Duck Flats during the critical early hours of a response. In 2017, the matrix was modified, and the Council, the City of Valdez, Valdez Fisheries Development Association, and Prince William Sound Aquaculture Corporation appealed that decision.

Earlier this year, the parties agreed to stay the appeal in lieu of a collaborative workgroup process. The workgroup’s goal is to reach consensus on how to ensure the protection of the Solomon Gulch Hatchery and Valdez Duck Flats. The buoys will provide scientific data to help the workgroup better understand how spilled oil will move in Port Valdez. This knowledge will help determine the timing for deploying protective boom.

Second buoy monitors Valdez Duck Flats

A second buoy has been deployed near the Valdez Duck Flats to monitor conditions in that location. The second buoy has been made possible by partnerships with Prince William Sound Science Center, the City of Valdez, and Valdez Fisheries Development Association.

The map shows the locations of the two sensitive areas of concern, as well as the location of the new buoys. The hatchery is a little over two miles from the terminal, and the flats are approximately four miles.

Piping inspections near completion

For the first time since the facility’s construction was completed in 1977, a majority of the large diameter crude oil piping at Alyeska’s Valdez Marine Terminal is undergoing a comprehensive inspection, both externally and internally. The inspections of these 36 and 48 inch diameter pipes began in 2016, and will be completed by the end of 2018.

Alyeska can use the data from these inspections to evaluate the current, complete condition of the large diameter piping used to move Alaska North Slope Crude onto tanker ships at the terminal.

A tremendous amount of work by Alyeska and their contractors is making these inspections possible:

Concrete foundations had to be reinforced to accommodate loading stresses associated with the inspections;
Piping inspection tool access and retrieval points had to be created at multiple locations;
Sharp bends and large valves had to be removed from certain piping sections to allow for the passage of inspection equipment;
The piping has to be cleaned of accumulated wax and debris after 40 years of use; and
With the exception of a few necessary, planned pipeline shutdowns, most of this work was done while crude oil was still flowing through the pipeline and tank ships were still loading.

North Slope crude oil spills into Port Valdez

On September 21, approximately 100 gallons of North Slope Crude oil was spilled into Port Valdez. The spill occurred during a planned annual leak-test of the pipes that load oil onto tankers out at the end of loading Berth 5 at the Valdez Marine Terminal.

To conduct the annual test, Alyeska Pipeline Service Company uses the berth’s fire system to pump seawater into the crude piping to a pressure of 190 PSI, or pounds per square inch. That pressure is held for a prescribed amount of time to allow inspectors to visually check the pipes for leaks. However, that day Alyeska was unable to achieve the necessary 190 PSI test pressure and an apparent operational error led to a mixture of crude oil and seawater being spilled into Port Valdez. Alyeska is conducting a thorough investigation of the spill.

Tom Kuckertz: Retired staff member still contributes engineering expertise to council’s mission

01/27/201701/27/2017 by Amanda Johnson

The council has benefited from Chicago-born Tom Kuckertz’ broad experience in engineering for 16 years and counting. After his retirement from the council in 2014, Kuckertz continued on as a volunteer for the committee he worked with most closely, the Terminal Operations and Environmental Monitoring Committee.

A young Kuckertz earned degrees in electrical engineering at the University of Illinois and the University of Idaho, followed by two years in the U.S. Army as a Signal Corps officer, where he was involved in the design and implementation of large communications systems.

“Basically, it involved how to move information from one place to another, and in most cases, deny access to adversaries,” explained Kuckertz.
