The OPH utilizes a semi-autonomous industrial platform designed for marine plastic remediation. Rather than active-capture mobility, it operates as a stationary "marketplace" to minimize fuel consumption.
- The Mother Ship (Hub): A semi-stationary processing platform utilizing Dynamic Positioning (DP) to maintain station within high-density plastic windrows.
- Drone Fleet: Autonomous, solar-powered skimmers that patrol the vicinity, collect debris, and deliver raw feedstock to the Hub.
- The Marketplace: A service-based incentive model where external vessels can trade collected marine debris for refined fuel, replacement parts, or currency.
The OPH achieves 100% operational energy self-sufficiency through three interconnected energy cycles.
- The Water Loop (Desalination): Uses waste heat from the pyrolysis reactor to pressurize seawater, which is then flashed into a low-pressure chamber.
- Output: Distilled water for plastic washing; industrial-grade sea salt.
- The Fuel Loop (Pyrolysis): Oxygen-free thermal degradation of collected plastics and synthetic textiles.
- Output: Plastic-Derived Oil (PDO), fractionated into Light Naphtha (saleable feedstock) and Heavy Fuel Oil (internal propulsion).
- The Gas Loop (Energy Recovery): Combustion of non-condensable gases (NCGs) and organic biomass.
- Output: High-temperature process heat for the pyrolysis chamber.
The OPH processes diverse marine waste streams through high-torque mechanical preparation and chemical neutralization.

- Chemical Neutralization: In-situ injection of calcium hydroxide (lime) to convert corrosive HCl gas (from PVC and dyes) into stable Calcium Chloride.
- Emissions Control: Multi-stage scrubbers (Activated Carbon + Alkaline) ensure clean exhaust.
- PFAS Remediation: Integration of hydrodynamic cavitation (collapsing vapor bubbles generating localized extreme heat and reactive radicals) and cold plasma flotation to extract and destroy forever chemicals (PFAS) from processed wastewater before discharge.
- Deoxygenation Mitigation: Post-processing effluent aeration and dissolved oxygen enrichment to counteract localized marine deoxygenation and support local aquatic life.
Depending on deployment location and energy needs, the OPH can be constructed using an alternative low-temperature process instead of standard pyrolysis.
- Low-Temperature Catalytic Hydrogen Conversion: Transforms mixed, unsorted plastics into high-purity hydrogen fuel while trapping the carbon in solid/liquid forms.
- Thermal Balancing: A calculated percentage of the generated hydrogen is combusted to provide the necessary thermal energy for the flash desalination Water Loop.
- Bonus Water Yield: The combustion of hydrogen produces pure water vapor, which is condensed directly into the distilled water tanks.
- Mitigation Needs: Requires automated regeneration cycles to prevent rapid catalyst poisoning from marine sulfur and halogen gases.
- Floating Tank Farms: Double-walled, modular storage tanks tethered to the Hub. These use seawater and salt ballast to maintain vertical stability and minimize structural stress.
- Offloading Logistics: Periodic rendezvous with commercial tankers to export surplus fuel and minerals to land-based markets.

- Phase 1 (Bench-scale): Validate the pyrolysis-to-flash-distillation thermal loop.
- Phase 2 (Pilot): Deploy a stationary, drone-supported Hub in a high-density controlled zone.
- Phase 3 (Industrial): Scale to full capacity with automated offshore mineral extraction and monomer recovery.
- Sustainability: The "Triple-Loop" system allows the Hub to operate indefinitely without external fuel inputs by converting the waste it collects into its own energy source.
- Environmental Impact: Beyond plastic removal, the system sequesters carbon in the form of solid "Char" bricks, which can be stored in the deep ocean or used in industrial applications.
