Smart Buoy with Rajant Connectivity

Date: Jan 2023

Enabling Reliable Subsea Data Transmission for Harvest Technology

Background

Harvest Technology required a smart buoy solution capable of transmitting critical subsea data to an offshore platform located 10 miles away. The project demanded a robust, long-range, and resilient communication system that could integrate seamlessly into Harvest’s remote monitoring solutions.

Ausco Products and Land and Sea Services were engaged to deliver a purpose-built smart buoy with Rajant Bread-Crumb connectivity, designed to withstand harsh marine environments while ensuring real -time subsea-to-surface-to-platform data flow.

Key Features

Hydrodynamic, corrosion-resistant buoy design.
Acoustic-optimised subsea transducer integration.
Rajant-enabled long-range wireless connectivity.
Fully integrated power, sensor, and communication systems.
Simulated testing for reliability and compliance.

Challenges

Transmitting data over long distances across open water poses significant technical hurdles:

Harsh sea conditions requiring a stable buoy design to protect sensitive electronics.
Reliable subsea-to-surface integration with transducers and receivers.
10-mile long-range wireless communication across a challenging marine environment.

Solution and Outcomes

Ausco engineered an integrated buoy system with a hydrodynamic design, marine-grade materials, and weatherproof enclosures to protect sensitive electronics. Subsea transducers were securely mounted with acoustic optimisation and noise reduction features, while Rajant connectivity ensured stable data transfer over 10 miles. The system was rigorously tested under simulated marine conditions to guarantee reliability.

This solution provided Harvest with reliable, real-time subsea-to-platform communications, reducing the need for vessel visits and improving safety by limiting personnel exposure. It also allowed immediate access to critical subsea data, enabling better asset management and operational decision-making.

Conclusion

Ausco Products successfully delivered a smart buoy solution with Rajant connectivity, en-abling Harvest Technology to transmit subsea data reliably over long distances in harsh off-shore conditions.

This project highlights Ausco’s expertise in integrated marine communication systems, combining robust engineering with advanced networking technologies to enable safe, efficient, and cost-effective operations.
