Vessel construction, planning underway for Crowley to Edison Chouest transition

Council conducting independent review of vessel designs By July of 2018, Edison Chouest Offshore, or ECO, of Louisiana will be the marine services contractor for oil tankers and the terminal in Prince William Sound. Until then, Alyeska and ECO will be working with Crowley Maritime, the contractor who currently provides those services, on a smooth transition between the two contractors. These services include escort tugs, general purpose tugs, oil recovery storage barges and associated personnel, all of which are key oil spill prevention and response assets for Prince William Sound. For instance, two state-of-the-art escort tugs accompany every laden tanker that leaves Port Valdez. One tug is tethered through the confined waterway called the Valdez Narrows, and one tug stands by at Hinchinbrook Entrance until the tanker is 17 miles into the Gulf of Alaska. The primary responsibility of these escort tugs is to rescue or “save” a tanker that may experience problems and prevent oil from spilling, and initiate response efforts should these prevention measures fail. … Continue reading

Conference focuses on best practices in towing rope technology

By Alan Sorum Council project manager A recent conference on rope design hosted by Samson Rope, a leading producer of high performance towing rope, shared best practices for towing that may be applicable in Prince William Sound. Founded in Boston in 1878, Samson is the world’s largest producer of ropes made with “Dyneema,” an ultra-high molecular weight polyethylene fiber. The company manufactures ropes of traditional fibers, like nylon and polyester. Samson provided the emergency towing equipment for the last two foreign-flagged tankers that called on the Valdez Marine Terminal. The International Maritime Organization, a United Nations agency tasked with improving maritime safety and preventing pollution from ships, requires tankers to carry an emergency towing package on their stern. In addition to this equipment, the Alaska Department of Environmental Conservation requires what is known as the “Prince William Sound Tow Package” to be carried on the bow of every tanker. This towing package consists of a messenger line, towline, buoy, and heavy-duty shackle that can be quickly deployed in an emergency. … Continue reading

Louisiana’s Edison Chouest Offshore to take over from Crowley in 2018 as Alyeska’s maritime contractor

Council invited to observe trainings, ship construction, on-water exercises In June, Alyeska Pipeline officially confirmed that Edison Chouest Offshore will take over from Crowley Maritime as the provider of oil spill prevention and response services for the terminal and tankers in Prince William Sound. The overlap of Crowley and Edison Chouest’s marine assets in Prince William Sound will take place over a three to six week period in the summer of 2018. The contract, signed in early August, is effective until 2028. Edison Chouest is planning five new escort tugs, four new general purpose tugs, three new barges, and two line boats. Construction of the general purpose tugs began this summer. Edison Chouest is planning to purchase two barges currently in Prince William Sound and build three new barges. Edison Chouest owns shipyards in the Gulf of Mexico, and the majority of the testing will be done nearby. Further testing will be done in Puget Sound and later in Prince William Sound once the vessels arrive in the region. Alyeska has promised further details about the vessels such as escorting performance specifications, firefighting capabilities, and spill response equipment in the near future. Observing the process The council is attending meetings along with ADEC, the Coast Guard, and Crowley for updates and information from Alyeska and Edison Chouest. Roy Robertson, the council’s drill monitor, has been attending on behalf of the council. “They have offered us the opportunity to observe vessel construction, crew trainings, and on-water exercises,” said Robertson. “We are setting aside funds for these trips to the shipyards and training facilities in the Gulf of Mexico.” … Continue reading

Foreign tankers arrive in Prince William Sound

Council observing process Two foreign-flagged tankers hauled Alaska North Slope crude oil from the Valdez terminal this summer for the first time in over 30 years. The last time non-U.S. vessels shipped Alaska crude to foreign refineries was in the 1980s when West Coast refineries could not keep up with the amount of crude coming out of the pipeline. The first tanker, the Tianlong Spirit, visited the terminal late last July and the second, the Cascade Spirit, arrived in early August. Both are chartered by BP, and owned by Teekay Corporation. A ban on selling U.S. oil was put in place during the 1970s Arab oil embargo in an effort to keep Alaskan oil in the U.S. At the time, the U.S. was in the middle of an energy crisis and gasoline prices were soaring. Alaska oil was exempted from the ban in 1995 under President Clinton, although the oil still had to be transported by U.S.-flagged tankers. Congress lifted the export ban for the rest of the U.S. in late 2015, which the Alaska delegation sought for the past 20 years. This change also allowed foreign tankers to transport oil out of the U.S. … Continue reading
