This summer, Alyeska’s multi-year internal inspection program of Valdez Marine Terminal piping included inspecting buried relief system and crude oil piping in and around the East Metering building, and from West Metering to the end of Berth 5. Much of this piping is encased in concrete and was considered “uninspectable” until recent advances in inspection technology.

Crews started in the spring, working in and around the East Metering building where oil enters the Terminal and is measured as part of the pipeline leak detection system. They built containment and installed equipment to allow for system isolation. The roof was modified so cranes could remove large segments of pipe from the building and return them after the inspection.

During a scheduled maintenance shutdown in June, TAPS personnel drained down and isolated the impacted piping around East Metering. Once the shutdown was completed, a contractor cleaned the pipe with special equipment that limited physical entry into the pipe. Crews removed several 90-degree pipe segments to create access points for the crawler pig (see photos) that carries the inspection tool through the pipe. Pigs inspected approximately 2,100 feet of pipe ranging from 16 to 36 inches in diameter.

Alyeska integrity management staff analyzed the data, and found no needed repairs and no significant impact to pipeline or Terminal operations. The piping has returned to service.

Homer teens use technology to monitor Kachemak Bay for aquatic invasions

Students put together the drones prior to a test drive.

Four Homer high school students, a project leader, and lots of volunteers took part in the center’s “Creating Teen Leaders through Marine Technology and Research” program this summer, helping monitor for aquatic invasive species throughout Kachemak Bay.

The students built an underwater remotely operated vehicle, or ROV, from a kit, which they used to explore the Homer and Seldovia harbors for aquatic invasive species. “We all had various skills that we could contribute but it took all of our expertise to organize, create, and improvise the structure,” said Landon Bunting, one of the students, describing the teamwork that developed between the students during the project.

The students also used drones to help learn to navigate the underwater ROV. “Flying the drones and watching them be flown allowed for a better understanding of operating ROVs through a ‘fluid’ such as air or water,” added Bunting. “This experiment allowed each of us to learn from our mistakes and to learn the benefit of different types of remote operated vehicles.”

Crowley Marine Services, the contractor who provides oil spill prevention and response services to Alyeska Pipeline Service Company, will no longer provide those services after June 30, 2018.

Crowley has held this contract with Alyeska since the company created its Ship Escort/Response Vessel System, also known as SERVS, after the Exxon Valdez oil spill. Crowley also provided tanker docking services since 1977, and helped dock the first tanker at the Valdez terminal.

Crowley owns the powerful tugboats that escort loaded oil tankers through Prince William Sound. The tugs also scout for ice drifting from nearby Columbia Glacier, and are equipped to start cleaning up a spill or tow a disabled tanker if needed. In addition to the escort tugs, Crowley owns response tugs that help the tankers dock and other support vessels and barges stationed in Prince William Sound which contain Alyeska’s boom, skimmers, and other equipment for a quick response to an oil spill.

Crowley employs 230 mariners and 17 administrative personnel in the area.
