OS-BREEZE: Oil Spills Boundary Red Emission Zone Estimation Using Unmanned Surface Vehicles.

Area of Science:

• Marine environmental monitoring
• Oceanography
• Robotics

Background:

• Maritime transport is crucial for global trade but poses significant environmental risks, especially marine oil spills.
• Human activities cause approximately 90% of near-shore marine oil spills, necessitating effective surveillance.
• Current monitoring techniques for oil spills can be time-consuming and inefficient.

Purpose of the Study:

• To introduce a novel technique, OS-BREEZE, for rapid and accurate assessment of marine oil pollution.
• To reduce the path length required for mapping and estimating the size of oil-contaminated areas.
• To demonstrate the enhanced speed and efficiency of the OS-BREEZE method compared to traditional techniques.

Main Methods:

• Development of the OS-BREEZE algorithm for directing an Unmanned Surface Vehicle (USV).
• Utilizing a USV to assess the extent of oil pollution on the sea surface by tracking spill edges.
• Conducting scale model experiments at the Coastal and Marine Engineering Research Institute (CAMERI) across four distinct spill scenarios.

Main Results:

• The OS-BREEZE algorithm enables USVs to efficiently map oil spill extents.
• The method significantly reduces the required path length for monitoring compared to conventional approaches.
• Scale model experiments confirmed the enhanced speed and efficiency of OS-BREEZE in various simulated spill conditions.

Conclusions:

• OS-BREEZE offers a novel and effective solution for monitoring and managing marine oil pollution.
• The USV-based approach provides a faster and more efficient method for assessing sea surface contamination.
• This technology has the potential to significantly improve response times and reduce the environmental impact of oil spills.
