Fleet Monitoring

Compliance infrastructure, not a dashboard

Poseidon Ledger integrates directly with vessel telemetry to produce verified, real-time emissions data that satisfies port authority, EU ETS, and insurance requirements without manual data entry.

01
◈

Telemetry Integration

Poseidon connects to your fleet's existing instrumentation — engines, fuel sensors, AIS transponders — via hardware-agnostic integration. No manual data entry. Continuous, tamper-evident data stream from day one.

72-hour setup · hardware-agnostic · encrypted data pipeline

02
⬡

Real-Time Green Zone Compliance

Every voyage is mapped against current and upcoming Green Zone boundaries. Fleet managers receive automated alerts when a vessel's route enters a compliance-sensitive corridor, with port-specific documentation generated automatically.

Live route monitoring · automated alerts · port-ready docs

03
◎

Verified Carbon Certification

Each voyage produces a verified Carbon Passport — a digital certificate of emissions performance accepted by port authorities, insurance underwriters, and charter clients. Third-party verified. Legally defensible. Commercially deployable.

Third-party verified · Gold Standard offsets · shareable credential

04
⊞

ETS Liability Forecasting

The Poseidon ETS engine calculates your fleet's carbon cost exposure 12–36 months forward, enabling fleet managers and owners to make propulsion upgrade decisions backed by data rather than regulatory guesswork.

◇

Charter Client ESG Pack

Every charter booking generates a shareable ESG credential for the charterer — voyage carbon footprint, offset certificates, vessel compliance rating. Agencies using Poseidon command a verified premium with ESG-conscious UHNWI clients.

Shareable PDF + digital badge · client-facing branding

Insurance & Legal Reporting

Poseidon produces data packages formatted specifically for Pantaenius, Lloyd's, and peer underwriters — enabling premium reduction negotiations backed by verified performance data, not declarations.
