Company Overview
Based in California, the company develops advanced buoy-based wave energy conversion systems that transform ocean motion into reliable electrical power. Its engineering team specializes in intelligent control platforms designed to maximize efficiency under dynamic marine conditions. As pilot programs expand, the organization continues advancing scalable offshore renewable infrastructure for commercial energy production.
The Challenges
Real-Time Edge Processing Requirements
Wave energy conversion depends on continuous interpretation of motion data, load feedback, and power regulation signals. The buoy’s onboard controller must execute adaptive control algorithms in real time without latency. Insufficient processing performance would directly impact energy conversion efficiency and system responsiveness.
Deterministic CAN-Based Subsystem Control
Marine actuators and embedded control modules rely on deterministic CAN communication. Two independent CAN channels were required to separate critical control logic from monitoring systems. Without native CAN support, external converters would introduce additional wiring complexity and potential failure points in a moisture-exposed offshore enclosure.
Offshore 4G/LTE Connectivity
Because wave energy buoys operate far beyond wired infrastructure, cellular backhaul is mission-critical. 4G/LTE connectivity was mandatory to transmit operational telemetry, receive firmware updates, and enable remote diagnostics from shore-based monitoring centers. Loss of connectivity would reduce visibility into system performance and asset health.
High-Bandwidth Network Integration
The wave platform integrates power conditioning units, sensor arrays, safety controllers, and diagnostic modules. Four 2.5GbE LAN ports were required to create a segmented and scalable onboard network without external switches. Limited Ethernet capacity would restrict future subsystem expansion as deployments scale.
Industrial Durability and Environmental Compliance
Offshore deployments expose electronics to vibration, salt air, temperature fluctuations, and unstable power conditions. The system required extended operating temperatures from –40°C to 55°C, shock and vibration validation, and UL-certified safety compliance. GPS capability was also preferred to support buoy positioning and fleet-level asset tracking.
