Smarter Oceans.

Smart Environmental Marine Systems (SEMS) is developing scalable offshore infrastructure platforms combining non-lethal shark mitigation with autonomous ocean intelligence.

Strategic Vision

Next-Generation Infrastructure for Sustainable Oceans

Traditional shark mitigation relies on physical capture. SEMS influences behaviour through technology, transforming coastal safety from a single-purpose expense into a multi-use intelligence asset.

Non-entangling architecture with zero mesh
Zero permanent seabed infrastructure
Autonomous renewable operation 24/7

Scalable Tech

Modular design allows for protection of perimeters from 30m pilot spans to full commercial beach deployments.

Whale Safe

Designed specifically to avoid entanglement using controlled subsurface geometry and breakaway links.

Core Technology

The SCDA-Hybrid Platform

Smart Buoy Nodes

Autonomous Power Hubs

Each surface buoy operates as an independent smart station containing solar generation, system diagnostics, and remote monitoring.

  • • LiFePO4 Battery Storage
  • • MPPT Charging Systems
  • • LoRaWAN/Satcom Telemetry
Emitter Backbone

The "Electric Curtain"

A controlled-depth subsurface backbone creates a distributed deterrent field without creating a physical barrier for marine life.

  • • Capacitive Field Layer
  • • Titanium Reinforcement Nodes
  • • Controlled-depth Subsurface
Electrical Concept

Behavioural Mitigation

Utilizes a high-voltage, ultra-low average current pulsed system designed to overstimulate shark electrosensory systems.

  • • 500V - 1,000V Peak Pulses
  • • Adaptive Pulse Frequencies
  • • Zero Habitat Harm

Scientific Development Pathway

STAGE 01
Feasibility

Computational COMSOL modelling and mechanical wave loading analysis.

STAGE 02
Lab Testing

Field measurement, electrode durability, and material corrosion testing.

CURRENT STATUS
Stage 3: Pilot

Offshore trial deployment of 3 autonomous buoys across a 30-60m span.

STAGE 04
Commercial

Full-beach deployment and integration with existing networks.

Ocean Data Intelligence

Multi-Purpose Asset

Autonomous Marine Observation Stations

"Traditional shark mitigation represents an ongoing operational cost. SCDA-Hybrid transforms that footprint into a multi-purpose coastal intelligence asset capable of supporting science, climate research, and coastal management."
