oPod™ Mini
Autonomous Buoy for Real-time Marine monitoring
Scalable to fleet deployment
Each unit is designed for oPod network compatibility, ready for interlinked, fleet-scale deployments.
The oPod™ Mini is a compact, self-powered, multiparameter marine monitoring buoy for ocean and coastal deployments.
At 49kg, it can be deployed by two operators from a small vessel for rapid, low-cost installation allowing users to deploy and collect data with no technical expertise required (recommended handling guidelines apply).
Durable multi-parameter sonde
Measured parameters include temperature, pH, dissolved oxygen, salinity, turbidity, and chlorophyll-a. The sonde is equipped with a self-cleaning brush that effectively cleans the measurement surface, removes bubbles, prevents microbial attachment, and ensures stable performance.

Physical Specifications
Operational Advantage
-
Low recovery operation (~9°/0)
Reduces fouling, extends membrane life, and lowers maintenance requirements -
Near-ambient brine discharge
Simplifies environmental approvals and reduces discharge impact -
Improved feedwater quality
Offshore intake accesses cleaner, more stable water, reducing pretreatment and chemical use -
Reduced operational risk
lower exposure to algal blooms, oil spills, and coastal contamination events improves system reliability
Modular Scaling
-
Plug-and-play RO modules
Enable rapid maintenance, simplified servicing,
and minimal downtime -
Standardised units deployed in parallel:
- 5 units: ~100-125 m3/day -
Linear, predictable scaling
Allows capacity to be increased incrementally to meet demand -
Staged deployment
Reduces upfront capital investment and enables capacity
to align with operational needs
