SUMMARY:Recent Advancements In Prince William Sound Open Water Response Ca
 pabilities
DESCRIPTION:Paper\n\nMark Ploen (QT Environmental) and Eric Haugstad (Mara
 thon Petroleum Company, Tesoro Corporation)\n\nIn 1990 a new planning stan
 dard was established for Prince William Sound contingency plan holders to 
 address gaps in previous requirements. The planning standard requires 300,
 000 bbls of recovery within 72 hours of an incident (Alaska 18 AAC 75.400-
 495 and Federal 33 CFR Part 155). In response to the new planning standard
  contingency plan holders implemented an open water recovery program which
  included 4 skimming barges incorporating recognized proven oil spill cont
 ainment and recovery equipment. \n\nIn 2007 the contingency plan holders f
 or Prince William Sound commissioned a project to identify “Best Achievabl
 e Technology” to evaluate potential improvements for open water response. 
 A literature review of existing technologies was conducted, and several te
 chnologies were chosen for testing at the Ohmsett test tank in New Jersey.
  For transparency, Alaska Department of Environmental Conservation (ADEC),
  Prince William Sound Regional Citizens’ Advisory Council (PWSRCAC) and Un
 ited States Coast Guard (USCG) were invited to witness all testing and sea
  trials and provided project updates and test reports.   Alaska North Slop
 e (ANS) crude was shipped to the Ohmsett test tank for use in testing and 
 time was scheduled at the facility to coincide with cold winter conditions
  to emulate climate and product consistent with a release in Prince Willia
 m Sound. An oleophilic skimmer with an innovative “fuzzy” coating was sele
 cted for further evaluation and sea trials after achieving the established
  recovery performance criteria. Additional laboratory and Ohmsett tests to
  evaluate endurance, debris handling and cold climate performance of the s
 elected skimmer were carried out by a third-party consulting group.  \n\nI
 n 2009 sea trials were conducted in Kachemak Bay to determine the optimal 
 configuration for feeding recovered oil to the selected skimmer. After tes
 ting several different containment boom options and configurations an adva
 ncing boom that incorporates a separator chamber in the apex was selected 
 as the optimal configuration for the selected skimmer. \n\nOver the next s
 everal years a series of modifications to one of the open water recovery b
 arges in Prince William Sound took place as “Proof of Concept” for the sel
 ected skimmer and advancing boom. ADEC, PWSRCAC and USCG were involved and
  witnessed each evolution of the “Proof of Concept” modifications and sea 
 trials. \n\nIn 2018, as a result of the ambitious project initiated in 200
 7 four new purpose-built Oil Spill Response Barges incorporating “Best Ach
 ievable Technology” were delivered in Prince William Sound marking a drama
 tic increase in oil spill response efficiency and capability.\n\nTag: Prev
