Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
Pneumatic Fender Pressure Monitoring (ISO 17357)
Early detection of fender pressure loss
Pressure
Quick Overview
| Problem | Pneumatic fenders rely on internal pressure for performance, but pressure is not always continuously monitored across all assets. |
| Solution | SENSAiO pressure sensors provide continuous monitoring of internal fender pressure. |
| Value | Improved visibility on pressure condition, supporting earlier detection of underpressure, leakage, or degradation. |
| ATEX | Typically non-ATEX; adapted configurations available if installed in hazardous fuel transfer zones. |
The Operational Challenge
Pneumatic fenders are used in marine and port operations to:
- Absorb energy during vessel berthing
- Maintain safe point between ship and quay
- Protect both vessel and infrastructure
According to ISO 17357, fender performance is directly linked to internal pressure.
From a physical perspective:
- The fender contains compressed air
- Internal pressure defines stiffness and energy absorption capacity
- Pressure decreases over time due to permeation or leakage
Typical operational issues include:
- Gradual pressure loss due to micro-leakage
- Damage to outer layers affecting integrity
- Improper inflation levels
- Pressure variation due to temperature changes
Detection challenges include:
- Manual pressure checks performed infrequently
- Large number of distributed fenders
- Exposure to harsh marine environments
- Lack of centralized monitoring
As a result, underinflated or degraded fenders may remain in operation without detection.
Why Pressure Monitoring Matters
Pressure is the key parameter governing fender performance.
By continuously monitoring pressure:
- Compliance with design conditions (ISO 17357) can be verified
- Pressure loss trends can be identified
- Maintenance needs can be anticipated
Typical interpretations include:
- Gradual pressure decrease may indicate leakage or permeation
- Sudden pressure drop may indicate damage
- Stable pressure indicates consistent performance
Pressure data reflects the mechanical readiness of the fender to absorb impact energy.
SENSAiO Solution
SENSAiO deploys wireless pressure sensors installed on:
- Pneumatic fenders
- Inflation valves or accessible pressure points
Sensors measure internal pressure and transmit data via LoRaWAN to a centralized monitoring platform.
The system provides:
- Continuous pressure monitoring
- Trend analysis across fender fleets
- Alerts on abnormal pressure deviations
It is important to clarify that:
- SENSAiO is a monitoring-only system
- It does not inflate or regulate fender pressure
- It does not repair damaged fenders
- It does not replace inspection or certification requirements
The system supports operational awareness and maintenance planning.
Results and ROI
ATEX Compliance and Safety
Pneumatic fenders are generally used in non-hazardous environments, but may be installed near fuel transfer operations.SENSAiO sensors:
- Can be provided with ATEX / IECEx certification when required
- Are suitable for marine industrial environments
- Are designed for outdoor and harsh conditions
All equipment is delivered with appropriate certification documentation where applicable.
SENSAiO systems are not safety systems and do not replace operational procedures or regulatory safety requirements.
Integration and compatibility
| Protocols | LoRaWAN, MQTT, REST API |
| Gateways | Compatible with standard LoRaWAN gateways (Kerlink, Multitech, Cisco, etc.) |
| Systems | Integration with port asset management systems |
| Deployment | Suitable for retrofit on existing fender fleets |
FAQ - Common Questions
Are Sensa.io sensors compatible with any gateway or network?
What ATEX certifications apply to Sensa.io devices?
All hazardous-area models are certified Ex II 2 G Ex ia IIC T4 Gb and IECEx approved for Zones 0–2.
What is the typical battery life?
Up to 10 years at 15-minute intervals, depending on signal strength and environment.
How are the sensors integrated into existing systems?
Through standard protocols — LoRaWAN, Modbus, MQTT, REST API — no proprietary middleware needed.
How does predictive maintenance reduce OPEX?
Early anomaly detection reduces emergency interventions by 30–40 %, extends equipment life and lowers energy costs.
What does the Sensa.io Valve Position Sensor actually measure?
The device detects real-time valve position states—open, closed, or intermediate—with high accuracy. It continuously sends this information wirelessly to your monitoring dashboard.
Can this sensor detect partial valve movement or stuck valves?
Yes. The sensor identifies irregular patterns such as partial movement, delayed response, or stuck valves, enabling early maintenance before failure occurs.
Is this sensor suitable for manual, motorized, and actuated valves?
Yes. It supports a wide range of valve types including ball, gate, butterfly, actuator-driven, and manual valves.
How fast does it update the valve position?
You can configure the reporting interval—from seconds to minutes—depending on your operational and battery needs.
How long does installation take?
Most installations take under 10 minutes. The sensor mounts using brackets or clamps without modifying existing valves.
