PASSIVE ACOUSTIC MONITORING

PAM with detection and alert in less than 3 seconds

Sinay’s PAM buoys detect, classify, and alert in seconds with AI, so work pauses inside
the mitigation window and resumes the moment it’s safe to continue.

• The problem

Most PAM systems can't keep up with modern offshore work

Detection is too slow to prevent the harm it's meant to flag.

Staffing costs scale with project length, regardless of project value.

A few hours of lost coverage can break the compliance record.

• The solution

Sinay’s PAM buoy thinks, runs, and reports on its own

Sub-3-second alerts from a buoy that runs unattended for 365 days.

01 · Edge AI

AI detection runs on the buoy, not in the cloud

Sinay’s buoys process acoustic data locally on a Deep Neural Network model, so detection and classification happen in under three seconds. The alert then transmits over Wi-Fi, 4G, or satellite.

02 · Autonomy

365 days of autonomous operation

Solar panels and lithium iron phosphate batteries power the buoy for a full year without intervention. Software updates, reboots, and diagnostics run remotely over 4G, so a year-long deployment doesn’t require a year of crew.

03 · Compliance

Regulator-ready audit logs

Every detection, noise level, and threshold event is logged continuously and exported in the formats regulators ask for. The dashboard handles ISO 18405, OSPAR, ACCOBAMS, DCSMM Descriptor 11, NMFS, and German national standards.

ONE DASHBOARD

One dashboard for alerts, validation, and reporting

Every alert lands on the dashboard with a spectrogram and audio clip, so operators can validate or reject in one click. Noise levels, detections, and buoy health stream live, and compliance reports export when you need them.

Marine Mammal Alerts
Know if marine mammals are present in real time.

Noise Levels
Real-time display of noise levels.

Threshold Alerts
Real-time alerts when noise crosses PTS or TTS limits, flagged as priority when a marine mammal is in the area.

Reports
Standardized or personalized reports over a defined period.

Cloud Access
24/7 access from any browser, with user permissions and live buoy GPS positions on a map.

Multi-sensors
Connect external sensors to the buoy and pull every reading into the same dashboard.

How a deployment works

Be up and running in 4 to 6 weeks

Sinay handles the buoy, the algorithms, the deployment at sea, and the
operator training. You provide the site coordinates, the regulatory thresholds,
and the decision protocols.

What Sinay handles

Buoy preparation

Hydrophones, recorders, and AI processing units configured to your project.

Algorithm tuning

Detection models calibrated for target species and local noise profile.

Dashboard setup

Alert thresholds, reporting intervals, and user access configured to your team.

Maritime deployment

Transport, crane lifting, and anchoring handled by Sinay’s marine ops team in collaboration with your crew.

Connectivity setup

4G, Wifi, or satellite transmission configured and tested before handover.

Operator training

Two-to-four hour onboarding on dashboard, alerts, and decision protocols.

What you'll provide

Site information

Deployment coordinates and bathymetric data for the monitoring zone.

Regulatory thresholds

The PTS and TTS limits for your target species, with guidance from Sinay’s regulatory team when needed.

Vessel access

Access to vessel or marine infrastructure for buoy deployment, if applicable.

Decision protocols

Internal rules for work suspension when an alert fires.

DEPLOYMENT MODEL

Static buoys

Anchored for port construction and offshore wind installation zones.

PAM built for projects that can’t stop

Frequently asked questions

We’re here to help with all your questions and answers in one place. Can’t find what you’re looking for? Reach out to our support team directly.

Is Sinay's PAM approved for use in our regulatory jurisdiction?

Sinay’s PAM aligns with ISO 18405, OSPAR, ACCOBAMS, DCSMM Descriptor 11, NMFS, and German national standards. The system has been deployed under permits in EU waters and the French Caribbean. For other jurisdictions, our regulatory team works with your environmental consultant during permit submission to confirm alignment.

How accurate is the AI detection?

Peer-reviewed validation puts detection at 96% on porpoise clicks and 91% on dolphin whistles, with a false alarm rate under 0.005% (Belghith et al., 2018). The AI requires roughly 80% confidence before an alert fires. Every alert includes a spectrogram and audio clip, so operators can validate or reject in one click.

Do we still need PAM operators on the vessel?

Your crew handles alerts from the dashboard. Projects that require an onboard operator for regulatory reasons can still validate alerts through the dashboard.

What happens if the buoy loses connectivity?

The buoy keeps running. Detection, classification, and logging all happen onboard, so a connectivity drop doesn’t interrupt monitoring or create gaps in the log. The buoy transmits over Wi-Fi or 4G, and if the connection drops, data is stored onboard and syncs once it returns.

Does this work alongside our existing PAMGuard setup?

Yes. Sinay supports PAMGuard’s detection algorithms and can integrate them directly into its processing pipeline. Sinay also operates its own proprietary detection algorithms, developed and maintained in-house. All detections produced by Sinay’s algorithms are visualised directly on the PAM Dashboard.

Each solution can be used independently depending on the project requirements, or both can run in parallel to cross-validate detections and maximise performance.

How long can the buoy run before maintenance?

The buoy runs continuously, with routine maintenance scheduled regularly depending on project scope. It doesn’t require an onboard crew between visits. Solar panels and lithium iron phosphate batteries keep it powered year-round, and the Grand Port Maritime de Guadeloupe deployment is now in its second year on this model.

Who owns the data the buoy collects?

You do. All acoustic data, detections, and reports from your deployment are your property. Sinay stores “everything on the cloud platform with role-based access controls, and standard export formats (CSV, PDF) make it straightforward to share with regulators or archive at project close.”
