Popis: Concentrated ice cover in a marine environment reduces the wave energy needed to disperse chemically-treated oil slicks. ExxonMobil is currently evaluating a concept to utilize the propeller wash from vessels to enhance chemical dispersion. Tests in an arctic basin utilizing a 1:25 scale model of an azimuthal-stern-drive platform-standby icebreaker resulted in effective dispersion (over 90% in most cases) on light oil and confirmed that such an icebreaker working in a sea-ice environment could efficiently contact and disperse oil. Future plans are to evaluate a diversion-boom system that will allow using propeller wash from conventional platform-standby or response vessels in both lightice and open-water conditions.
