Introduction to EBOSS Technology

Overview of the Presentation

• The presentation will cover new information on detecting, locating, classifying, and identifying buried objects in the seafloor, including UXO and other infrastructure.

• Rick Babbittz introduces himself as a former naval officer with 37 years in marine electronics, focusing on the EBOSS project for over 20 years.

Historical Context

• The technology's roots trace back to the 1990s when a need for small-scale UXO cleanup was identified in locations like Ordinance Reef and Vicas Land.

• In 2008, images from HMS Service sunk in Narragansett Harbor were captured using a precursor system to EBOSS.

Advancements in Imaging Technology

Evolution of Image Rendering

• Initial imaging took about 10 days; advancements now allow near-instantaneous rendering due to improved algorithms and hardware.

• New materials and technologies enable effective buried mine detection in both 2D and 3D formats at sea.

Real-world Applications

• Recent surveys off Denmark revealed known UXO fields, showcasing practical applications of the technology.

• Commercial customers are utilizing EBOSS for extensive pipeline surveys and even treasure hunting endeavors.

Practical Uses of EBOSS

Surveying Capabilities

• Customers use EBOSS for pre-sight surveys related to oil and gas pipelines, uncovering previously hidden minefields or UXOs.

• A specific example includes surveying a PB4Y bomber wreckage where EBOSS can distinguish between broken versus buried components.

Unique Features

• The system provides an MRI-like capability that allows operators to see through layers of sediment covering objects.

Technical Specifications

Coverage and Resolution

• The typical swath width is around 20 meters at optimal heights above the seabed; penetration varies based on soil type (2–3 meters in sand).

• At higher altitudes, wider swaths can be achieved but may sacrifice resolution; combining data with magnetometers enhances results.

Data Processing

• The system operates at up to four knots with voxel resolutions down to 5 cm; processing generates significant amounts of data (100 GB/hour).

System Components

Design Features

• Comprises multiple subwater receivers arranged across panels; smaller iterations are being developed for various platforms.

Deployment Methods

• Can be mounted on different vehicles such as ROV systems or used with shallow water mounts for restricted environments.

Operator Interface

User Experience

• Operators view real-time data through plan views and profiles while conducting surveys. Adjustments can enhance visibility by filtering out noise from hard surfaces.

Data Manipulation

• After collecting data, operators can quickly download it into third-party software for detailed analysis in three dimensions.

Advanced Analytical Tools

Third-party Software Integration

• Collaboration with software providers enables automatic detection features like boulder identification during analysis.

Georeferencing Capabilities

• Allows precise mapping of cables and pipelines under the seabed using advanced visualization techniques across multiple views.

Conclusion: Future Directions

Ongoing Research & Development

• Continuous improvements are being made through partnerships with institutions like the University of Washington focusing on infrastructure location studies.

Final Thoughts

• Rick Babbittz emphasizes that EBOSS was initially intended for cleanup operations but has evolved into a versatile tool applicable across various sectors.
