Prince William Sound has a hive of activity this summer. On July 1, Alyeska’s marine services contractor transitioned from Crowley Maritime Corporation to Edison Chouest Offshore.

This transition means all of the escort tugs and much of the spill prevention and response equipment in Prince William Sound are brand new, or new to the Sound.

Demonstrations of the new equipment

The Alaska Department of Environmental Conservation required that each vessel and crew member demonstrate their capabilities before beginning service. Each tug, as well as each tug’s captain, had to perform a set of maneuvers which differed according to the vessel and its purpose.

Changes to oil spill contingency plans approved

Extensive amendments due to transition

Photo of oil spill contingency plans with the caption: What is a contingency plan? A contingency plan, or “c-plan,” outlines steps to be taken before, during, and after an emergency. An oil spill contingency plan contains detailed information on how to prevent an oil spill, as well as response activities in the event a spill occurs. Preventing an oil spill from occurring in the first place is the most effective way to protect human health and the environment. If an oil spill occurs, however, a systematic and well-organized approach is necessary to quickly contain and control a spill. Responding efficiently and effectively to a spill requires advanced planning and preparedness.
What is a contingency plan?

The Alaska Department of Environmental Conservation recently approved major amendments to oil spill contingency plans for both the Valdez Marine Terminal and for the tankers that transport oil through Prince William Sound. Both approvals came with conditions.

Neither the tanker plan, nor the terminal plan was due for a renewal. However, Edison Chouest Offshore is bringing so much new equipment and personnel to their new role as Alyeska’s marine services contractor that major changes were needed to both plans. Major amendments require a public comment period.

Prince William Sound Tanker Oil Spill Contingency Plan

Council Project Manager

Updates to two oil spill prevention and response contingency plans are currently underway. The Alaska Department of Environmental Conservation, or ADEC, solicited public comments regarding the changes to the spill prevention and response plans this past summer.

The plans are prepared by the operators of Alyeska’s marine terminal and oil tankers and are subject to state approval. These plans specify what operators will do to prevent and clean up oil spills. There are separate plans for spills from the Valdez Marine Terminal and from the tankers that carry oil. Both plans undergo an approval process approximately every five years. With the marine services transition in Prince William Sound, Edison Chouest Offshore’s new equipment means the details in the plans will change, triggering a public review.

In 43 pages of formal comments submitted to ADEC in August and September, the Council made a number of recommendations to either maintain the same level of preparedness or improve the proposed plans.

Report identifies concerns with tanker escort tugs being built for service in Prince William Sound

The council has identified some areas of concern with the design of the new escort and general purpose tugs under construction by Edison Chouest Offshore for use in Prince William Sound. These concerns and recommendations result from a council-commissioned analysis of the tugs by Robert Allan Ltd., a naval architecture and marine engineering company.

Edison Chouest Offshore is taking over the marine services contract for Alyeska Pipeline Service Company in the summer of 2018. Crowley Maritime has held the contract since the creation of Alyeska’s Ship Escort/Response Vessel System after the Exxon Valdez oil spill. The services provided under this contract 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 the Valdez Marine Terminal and associated oil tankers operating in Prince William Sound. Robert Allan Ltd. was contracted by the council to review and evaluate drawings and other vessel design materials provided by Alyeska Pipeline Service Company. This review includes information that was provided to the council as of December 14, 2016.
