The Council is beginning a project to better define weather at the Hinchinbrook Entrance to Prince William Sound, Alaska. Wind and wave conditions affect the transit of oil-laden tankers through Hinchinbrook Entrance, and can impact an oil spill response.
This project will look at wind speed and wave height in particular, as they most affect escort tugs attempting to rescue a stricken tanker at Hinchinbrook Entrance. Additionally, the study will look at navigability for oil spill response vessels and the probability of the concurrent occurrence of darkness, freezing temperature, rain, snow, fog (low visibility), and sea spray icing conditions.
The Council hopes to answer two questions from this research:
- How often do extreme events and/or closure conditions (winds at 45 knots or seas exceeding 15 feet at Seal Rocks) occur at Hinchinbrook Entrance?
- How well does the definition or identification of a closure condition reflect the conditions actually experienced by vessels?
The information will be publicly available for industry and regulatory planners to help prevent oil spills and more effectively clean up a spill should one occur.
The council is inviting proposals for potential contractors to conduct this study.
The submittal deadline for proposals is August 18, 2017. Award announcement will be September 1, 2017. For more information, download the full RFP:
