1. Executive Summary
Three Scenarios
| Scenario | First Operational Campaign | Total Duration | Key Assumptions |
|---|---|---|---|
| Best case | Q3 2029 | 42 months | PoC compressed, hull pre-identified, Chinese shipyard, no regulatory surprises |
| Expected case | Q1 2031 | 54-60 months | Standard PoC timeline, normal procurement, moderate regulatory iteration |
| Worst case | Q3 2032 | 72-78 months | PoC delays, PyroGenesis complications, regulatory pushback on London Protocol, shipyard overruns |
Why This Takes 4-6 Years
This is not a software project. It combines:
- Novel technology validation (plasma gasification of ocean plastic — never done before)
- Marine classification of a novel vessel type (no existing class notation exists)
- Heavy industrial conversion (comparable to small FPSO conversions: 35 months average)
- Regulatory navigation of ambiguous international treaties (London Protocol interpretation)
- Multi-round capital raising ($68-173M total CAPEX)
2. Comparable Project Timelines
The Ocean Cleanup — System 03
| Milestone | Date | Duration |
|---|---|---|
| Concept (Boyan Slat's TEDx talk) | 2013 | — |
| Crowdfunding ($2.2M) | 2014 | Year 1 |
| North Sea prototype test (100m segment) | 2016 | Year 3 |
| System 001 deployed from San Francisco | September 2018 | Year 5 |
| System 001 failed, returned to port | January 2019 | Year 6 |
| System 002 "Jenny" deployed | July 2021 | Year 8 |
| System 03 transition begins | 2022 | Year 9 |
| System 03 fully deployed to GPGP | August 2023 | Year 10 |
| 50,000 metric tons removed (cumulative) | January 2026 | Year 13 |
Applicable to The Claw: The Claw benefits from existing vessel conversion practices (not building from scratch) and proven plasma technology (PyroGenesis PRRS has operated on land). The innovation is integration, not invention. This should compress the timeline vs. Ocean Cleanup's ground-up development.
PyroGenesis PAWDS — Contract to Sea Deployment
| Milestone | Date | Duration |
|---|---|---|
| US Navy evaluates waste management technologies | ~2001-2011 | 10 years evaluation |
| Factory Acceptance Testing (FAT) in Montreal | May 2011 | — |
| First PAWDS delivered to CVN-78 shipyard | Late 2011 | — |
| USS Gerald R. Ford launched | November 2013 | 2 years after delivery |
| CVN-78 commissioned | July 2017 | 6 years after delivery |
| First operational deployment with PAWDS | October 2022 | 11 years after delivery |
| CVN-79 PAWDS delivered | Pre-2024 | — |
| CVN-80/81 two-ship contract ($11.5M) | 2020 | — |
Applicable to The Claw: PyroGenesis built the PAWDS to spec in roughly 8-13 months (engineering design: 8 months, fabrication: 13 months for the military prototype). A civilian marine PRRS unit should take 12-18 months from contract to factory acceptance.
FPSO Tanker Conversions — Industry Average
| Metric | Duration | Source |
|---|---|---|
| Contract to first oil (conversion) | 34-35 months | Industry average across multiple projects |
| Contract to first oil (newbuild) | 55-57 months | Industry average |
| Standardized hull (SBM Fast4Ward) | 12 months less than conventional | SBM Offshore program |
| Range of actual projects | 15-60 months | Highly variable by complexity |
Applicable to The Claw: The conversion itself (steel work, systems installation, outfitting) should take 18-24 months at a competent shipyard. Add 6-12 months for engineering design review with classification society. Total from hull purchase to operational: 24-36 months.
Gaia First — Ocean Waste 2 Energy Vessel
| Milestone | Date | Status |
|---|---|---|
| Concept announced | ~2020 | — |
| UNESCO partnership | 2021 | — |
| First funding round sought (EUR 750K) | ~2022 | Unknown if closed |
| Planned maiden voyage | 2024 (original estimate) | Not achieved |
| Current status | 2026 | Still in development |
Applicable to The Claw: Validates that ocean processing vessels require serious capital commitment. A EUR 750K funding target is insufficient. The Claw's $1.5-4.5M PoC budget and $68-173M total CAPEX are more realistic for the scope.
The Manta (SeaCleaners)
| Milestone | Date | Status |
|---|---|---|
| Concept by Yvan Bourgnon | 2016 | — |
| Association founded | 2016 | — |
| Vessel design contract | ~2019 | — |
| Planned launch | Originally 2024 | Delayed |
| Current status | 2026 | Under construction, launch TBD |
3. Phase 0: Foundation (Months 0-6)
Calendar: March 2026 - September 2026 Capital required: $500K-$1M (Pre-seed: founder + angels) Purpose: Legal groundwork, team formation, PoC funding secured
Activities
| Activity | Duration | Cost | Deliverable |

| Advisory board formation | 1-3 months | Equity/honoraria | Maritime operations, plasma engineering, environmental markets, regulatory |
Decision Gate 0: PROCEED TO POC?
GO if:
- Legal opinion provides a credible pathway (not necessarily definitive approval, but no hard legal barrier)
- Classification society confirms the concept is classifiable in principle
- PyroGenesis confirms facility access and willingness to partner
- PoC funding ($1.5-4.5M) secured or high-confidence commitments
- Legal opinion concludes plasma gasification IS incineration under London Protocol with no viable counter-argument
- Classification society identifies a fundamental safety barrier that cannot be engineered around
- PyroGenesis refuses engagement or enters insolvency without alternatives
4. Phase 1: Proof of Concept (Months 3-21)
Calendar: June 2026 - December 2027 Capital required: $1.5-4.5M (Seed round) Purpose: Validate that plasma gasification works on ocean plastic. Produce data for classification society AiP and investor Series A
Stage 1: Feedstock Characterization (Months 3-5)
| Activity | Duration | Cost |
|---|---|---|
| Procure 500 kg ocean plastic samples (Oceanworks + 5 Gyres) | 4-6 weeks | $15-50K |
| Laboratory analysis: proximate, ultimate, calorific value, chlorine, salt, heavy metals, polymer ID | 4-6 weeks | $20-40K |

- Salt reducible below 0.5%
- No showstopper heavy metals
Stage 2: Bench-Scale Plasma Testing (Months 5-12)
| Activity | Duration | Cost |
|---|---|---|
| PyroGenesis engineering preparation | 6-8 weeks | $50-100K |
| Feedstock procurement for testing (5+ tonnes via Ocean Cleanup or charter expedition) | 4-8 weeks | $30-80K |
| Test campaign at PyroGenesis Montreal (PRRS 2 TPD prototype) | 8-16 weeks | $150-400K |
| 25-30 test runs across feedstock batches, moisture levels, feed rates, torch power | (included above) | — |
| 3-5 extended runs at optimal conditions (24-72 hours each) | (included above) | — |
| Independent laboratory analysis (slag TCLP, emissions, condensate) | 4-6 weeks | $40-100K |
| Third-party verification of results | 2-4 weeks | $20-50K |

- Net energy ratio > 1.0 at >= 15% moisture for at least one batch
- Syngas LHV >= 8 MJ/Nm3
- Dioxin/furan < 0.1 ng TEQ/Nm3
- Slag passes TCLP (non-hazardous)
- No catastrophic equipment failure from salt/chlorine
Stage 3: Extended Pilot Campaign (Months 12-21)
| Activity | Duration | Cost |
|---|---|---|
| Three extended campaigns (2-4 weeks continuous each) | 12-16 weeks | $400K-1.2M |
| Pre-processing line build and test (shredder, rinse, centrifuge, dryer) | 6-8 weeks lead, runs during campaigns | $200-600K |
| Additional feedstock procurement (5-15 tonnes) | 4-8 weeks | $50-200K |
| Continuous monitoring and reliability engineering | Duration of campaigns | $50-150K |
| Certified emissions stack testing | Per campaign | $50-150K |
| Final comprehensive report (investor + regulator + classification society grade) | 6-8 weeks | $50-100K |
- Uptime > 80% across all three campaigns
- Net energy ratio confirmed > 1.0 at realistic moisture
- Emissions consistently within MARPOL Annex VI limits
- No failure requiring > 48 hours repair
- Pre-processing demonstrates viable feedstock preparation
- Dataset sufficient for DNV/Lloyd's AiP submission
5. Phase 2: Design & Acquisition (Months 15-30)
Calendar: June 2027 - September 2028 Capital required: $15-30M (Series A) Purpose: Classification society approval, hull acquisition, conversion engineering, PRRS procurement
Note: Phase 2 overlaps with the tail end of Phase 1. Key Phase 2 activities begin during Stage 3 of the PoC, once Gate 2 (bench-scale success) provides sufficient confidence.
Classification Society Pathway
| Step | Duration | Timing | Cost |
|---|---|---|---|
| Formal AiP submission — concept design, PoC data package, operational profile, hazard identification | 3-6 months | Months 15-21 | $200-500K |
| AiP review and issuance — class society evaluates concept, issues AiP (or conditional AiP with requirements) | 3-6 months from submission | Months 18-27 | (included above) |
| Basic design review — hull structural analysis, stability calcs, fire/safety plans, PRRS integration design, HAZID/HAZOP | 6-12 months | Months 21-33 | $500K-1M |
| Class design approval — formal approval of conversion design | At end of basic design | Month 30-33 | (included above) |
This aligns with the regulatory pathway research (Phase 1: 3-6 months for AiP, Phase 2: 6-12 months for basic design review). The classification process is on the critical path — it must be substantially complete before shipyard conversion begins.
Hull Acquisition
| Step | Duration | Timing | Notes |
|---|---|---|---|
| Broker engagement | 1 month | Month 18 | Instruct 3-4 brokers (Clarksons, SSY, Fearnleys, Xclusiv) simultaneously |
| Market search & shortlisting | 2-4 months | Months 18-22 | Identify 5-10 candidate 17-22 year old Aframax hulls |
| Condition surveys | 2-4 weeks per vessel | Months 22-24 | Class surveyor + naval architect inspection. Hull thickness gauging, machinery condition, structural assessment |
| Negotiation & purchase | 2-3 months | Months 24-27 | MOA signing, deposit, flag transfer, delivery |
| Drydock inspection | 4-6 weeks | Month 27-28 | Full drydock survey, class approval for conversion baseline |
Key risk: Hull acquisition timing depends on market availability. The search can begin speculatively during PoC Stage 3, but firm commitment requires Series A funding and Gate 2 passage. A 6-month window from search to delivery is realistic; 12 months if the right vessel is not immediately available.
PRRS Plasma Unit Procurement
| Step | Duration | Timing | Notes |
|---|---|---|---|
| Licensing agreement with PyroGenesis | 3-6 months negotiation | Months 15-21 | Perpetual license, IP escrow, marine application rights |
| Marine PRRS engineering design | 8-12 months | Months 18-30 | Marinization: vibration isolation, corrosion protection, class-approved materials, marine electrical |
| Component procurement | 6-10 months | Months 22-32 | Graphite electrodes, refractory linings, plasma torches, transformer, cooling system |
| Factory fabrication | 8-13 months | Months 26-39 | Assembly at PyroGenesis Montreal or licensed fabricator |
| Factory Acceptance Testing (FAT) | 4-6 weeks | Month 39-40 | Run with test feedstock, verify all parameters |
Critical path note: PRRS procurement is the longest single lead-time item. It MUST begin during PoC Stage 3 (Month 15-18) with preliminary engineering, even before Gate 3. The risk is that Gate 3 fails and the engineering work is wasted ($200-500K). This is an acceptable risk to avoid a 12+ month delay to the overall project.
Parallel During Phase 2
| Workstream | Duration | Months |
|---|---|---|
| Flag state selection & registration | 3-6 months | 18-24 |
| MARPOL compliance engineering | Ongoing | 18-30 |
| Methanol synthesis feasibility study (if syngas H2:CO ratio supports it) | 4-6 months | 18-24 |
| Collection system detailed design | 6-9 months | 21-30 |
| Verra methodology development (continues from Phase 0) | Ongoing, 2-5 years total | 0-60 |
| Corporate sponsorship negotiations | Ongoing | 18-36 |
| Crew recruitment planning | 3-6 months | 24-30 |
6. Phase 3: Conversion & Build (Months 27-48)
Calendar: June 2028 - March 2030 Capital required: $50-100M (Series A remainder + DFI debt + blended finance) Purpose: Convert the acquired hull into an operational plasma processing vessel
Shipyard Selection
| Factor | Chinese Yard | Turkish Yard | Singapore Yard | European Yard |
|---|---|---|---|---|
| Labour cost | Lowest | Low-medium | Medium-high | Highest |
| Conversion cost estimate | $15-20M | $18-25M | $25-35M | $30-40M |
| Quality track record | Variable (select carefully) | Good for conversions | Excellent | Excellent |
| FPSO conversion experience | Extensive (COSCO, Shanghai Waigaoqiao) | Limited | Extensive (Keppel, Sembcorp) | Moderate |
| Classification surveyor access | DNV/LR present at major yards | DNV/LR present | DNV/LR present | DNV/LR headquartered nearby |
| Proximity to Honolulu | Closer than Europe | Distant | Moderate | Distant |
Conversion Timeline
| Phase | Duration | Months | Key Activities |
|---|---|---|---|
| Mobilization & strip-out | 2-3 months | 27-30 | Vessel arrives at shipyard. Strip cargo systems (pumps, COW, IGS, cargo heating, manifolds). ~500-800 tonnes removed. Tank cleaning and gas-freeing. |
| Structural modifications | 4-6 months | 30-36 | Deck reinforcement for processing equipment (800-1,200 tonnes new steel). Reactor foundation (80-120 tonnes). Fire/blast walls (300-500 tonnes). Exhaust stack structure. Tank conversions for ballast, freshwater, waste storage. |
| Systems installation | 6-8 months | 34-42 | PRRS reactor and gas cleaning installation. Syngas engine/genset installation. Collection system (booms, davits, conveyors, dewatering). Electrical upgrade (1-2 MW new generation). Piping (waste feed, cooling, syngas, fire suppression). Accommodation expansion (28-50 berths). Navigation and comms upgrade. |
| PRRS installation | 3-4 months | 38-42 | Reactor module lowered into foundation. Torch alignment and connection. Gas cleaning train hookup. Power and cooling connections. Control system integration. |
| Outfitting & finishing | 2-3 months | 42-45 | Painting, insulation, safety equipment (lifeboats, fire suppression). Helipad installation. HVAC commissioning. Galley and accommodation fit-out. |

Compression Opportunities (Parallel Risk-Taking)
These activities can run in parallel to compress the timeline, but each carries risk if the preceding gate fails:
| Parallel Activity | Normal Start | Compressed Start | Risk |
|---|---|---|---|
| Classification pre-engagement | After PoC | During Phase 0 (Month 1) | Low — $10-30K, builds relationships |
| AiP submission | After Stage 3 | During Stage 3 (Month 15) | Low-Medium — uses Stage 2 data, update with Stage 3 data |
| Hull search | After Gate 3 | During Stage 3 (Month 12) | Medium — search is free, commitment requires funding |
| PRRS marine engineering | After Gate 3 | After Gate 2 (Month 12) | Medium — $200-500K at risk if Gate 3 fails |
| Series A fundraising | After Gate 3 | During Stage 3 (Month 15) | Low — use Stage 2 results for preliminary pitch |

Key Observations from the Workstream Map
1. The classification pathway is the hidden critical path. While PoC gets all the attention, the AiP + basic design review takes 12-18 months and cannot begin properly until PoC Stage 2 data exists. Starting pre-engagement in Month 1 is essential.
2. PRRS fabrication is the long pole. 18-24 months from engineering start to FAT. If it begins at Month 18 (after Gate 2), FAT is at Month 39-42, which must happen BEFORE installation at the shipyard (Month 38-42). This is razor-thin. Starting preliminary marine engineering at Month 12-15 provides necessary buffer.
3. Hull acquisition is NOT on the critical path — surprisingly. A 17-22 year old Aframax can be purchased in 3-6 months. The hull can arrive at the shipyard while conversion engineering is still being approved, with strip-out work starting immediately.
4. Funding must lead activities by 6-12 months. Series A must close by Month 18-24 to fund hull purchase (Month 24-27) and PRRS procurement (Month 18+). Build funding must close by Month 30-33 to fund conversion start (Month 27-30).
11. Funding Milestones Aligned to Timeline
What Must Exist Before Each Round
| Round | Amount | Timing | Prerequisites for Investors |
|---|---|---|---|
| Pre-seed | $500K-1M | Month 0-3 | Legal opinion commissioned. PyroGenesis MOU. Credible team. Business plan. Advisory board. |

12. Risk-Adjusted Timeline Scenarios
Best Case: 42 Months (Q3 2029)
Assumptions:
- Legal opinion positive within 3 months
- PoC compressed to 14 months (fast procurement, no equipment issues, PyroGenesis immediately available)
- Gate 2 results so strong that AiP submission begins at Month 10
- Hull pre-identified during PoC, purchased immediately after Gate 2
- PRRS marine engineering begins after Gate 2 (Month 10)
- Chinese shipyard with aggressive schedule (18 months conversion)
- No significant regulatory pushback
- Funding rounds close within 3 months of starting
Month 0: Pre-seed closed. Legal opinion + PoC begin.
Month 3: Gate 1 passed. Stage 2 begins.
Month 10: Gate 2 passed. AiP submitted. Hull search begins. PRRS engineering begins.
Month 14: Gate 3 passed. Hull purchased. Series A closed.
Month 16: AiP issued. Hull arrives at shipyard. Strip-out begins.
Month 18: Basic design review submitted. Build funding securing.
Month 20: PRRS FAT begins at PyroGenesis.
Month 22: PRRS delivered to shipyard. Installation begins.
Month 34: Conversion complete. Sea trials begin.
Month 38: Transit to Honolulu.
Month 42: First operational campaign.
Probability: 10-15%. This requires everything to go right and aggressive parallel execution.
Expected Case: 54-60 Months (Q1-Q3 2031)
Assumptions:
- Legal opinion takes 5 months (moderate complexity)
- PoC runs 18 months (standard schedule, one re-test needed in Stage 2)
- AiP submission at Month 15, issuance at Month 24
- Hull search takes 6 months, purchase at Month 24
- PRRS marine engineering begins at Month 15, FAT at Month 39
- Singapore or Chinese shipyard, 20-month conversion
- One round of regulatory iteration (flag state questions, class conditions)
- Each funding round takes 4-6 months to close
- 3-month schedule slip from unforeseen issues (weather, supply chain, personnel)
Month 0: Pre-seed. Legal opinion + classification pre-engagement begin.
Month 5: Gate 1 passed.
Month 12: Gate 2 passed. AiP submission begins.
Month 15: PRRS marine engineering begins. Hull search begins. Series A fundraising begins.
Month 18: Stage 3 begins. Series A closing.
Month 21: Gate 3 passed. AiP under review.
Month 24: AiP issued (with conditions). Hull purchased. Series A closed.
Month 27: Hull arrives at shipyard. Strip-out begins. Build funding begins.
Month 30: Basic design review approved. Structural work begins. Build funding closing.
Month 39: PRRS FAT complete.
Month 42: PRRS installation at shipyard.
Month 48: Conversion substantially complete. Harbour trials.
Month 51: Sea trials complete. Transit to Honolulu.
Month 54: First operational campaign begins.
Probability: 40-50%. This is the planning target.
Worst Case: 72-78 Months (Q3 2032)
Assumptions:
- Legal opinion inconclusive — requires second opinion or flag state consultation (+6 months)
- PoC Stage 2 shows conditional results (net energy ratio 0.7-1.0) — requires extended testing (+6 months)
- PyroGenesis enters creditor protection during Stage 3 — must secure data, find alternative fabricator (+6-12 months)
- AiP issued with significant conditions requiring additional engineering (+6 months)
- Hull market tight — acceptable vessel not available for 12 months
- Classification society requires HAZOP iteration (+3 months)
- Shipyard encounters structural surprises during conversion (+4 months)
- PRRS installation requires modifications for sea conditions discovered during trials (+3 months)
- Funding rounds take 9-12 months each due to market conditions
Month 0: Pre-seed.
Month 6: Legal opinion inconclusive. Commission second opinion.
Month 9: Gate 1 passed (delayed by feedstock sourcing).
Month 18: Gate 2 — conditional proceed (energy ratio 0.9). Extended testing planned.
Month 24: Extended Stage 2 testing confirms viability with pre-drying.
Month 30: Gate 3 passed (delayed). AiP submission with full data set.
Month 33: PyroGenesis enters creditor protection. IP escrow activated. Alternative fabricator sought.
Month 36: AiP issued with conditions. New PRRS fabrication partner identified.
Month 42: Hull purchased (delayed by market + funding timing).
Month 45: Hull at shipyard. Conversion begins. PRRS engineering restarted with new partner.
Month 57: PRRS FAT complete (new fabricator learning curve).
Month 60: PRRS installation.
Month 66: Conversion complete. Sea trials.
Month 72: Transit to Honolulu (after trial defect rectification).
Month 78: First operational campaign.
Probability: 20-25%. Multiple things must go wrong, but each individual risk is plausible.
Timeline Risk Register
| Risk | Impact on Timeline | Probability | Mitigation |
|---|---|---|---|
| Legal opinion says plasma IS incineration | PROJECT KILL or +12-24 months for treaty interpretation | Low (15%) | Commission from top-tier maritime firm. Prepare fallback arguments. Engage flag state early. |
| PyroGenesis bankruptcy | +6-12 months | Medium (30%) | IP escrow clause. Maintain relationships with key engineers. Identify alternative fabricators (Plazarium, Advanced Plasma Power). |
| PoC shows marginal energy balance | +6 months extended testing | Medium (25%) | Pre-define "conditional proceed" criteria. Budget for extended Stage 2. |
| Classification society imposes conditions | +3-6 months | Medium-High (40%) | Pre-engagement in Phase 0. Submit comprehensive data package. Budget for iteration. |
| Hull market spike / no suitable vessels | +3-12 months | Low-Medium (20%) | Begin search early. Consider multiple vessel types (large OSV as alternative). Instruct multiple brokers. |
| Shipyard conversion overrun | +3-6 months | Medium (35%) | Use experienced FPSO conversion yard. Fixed-price contract with LD clauses. Owner's engineer on site. |
| PRRS integration issues at sea | +2-4 months | Medium (30%) | Extended harbour trials. Gradual ramp-up. Budget for post-trial modifications. |
| Funding delays | +3-12 months per round | Medium (30%) | Maintain parallel funding tracks. Government grants as bridge. Keep burn rate low during fundraising. |
