Pelagix Ocean Electromagnetic Coupling Module

The Ocean Electromagnetic Coupling Module developed and manufactured by Pelagix enables non-contact, inductive underwater data and power transmission. Designed for oceanographic buoys, subsea subsurface mooring systems, and vessel-towed cable arrays, it offers a reliable solution for underwater data acquisition and telemetry. Solutions built around this electromagnetic coupling module feature simplified system design, low failure rates, and high operational convenience for offshore operations.

Key Features & Advantages

• Simultaneous Power & Data Telemetry 

  Utilizing the inductive coupling principle between a magnetic core ring and plastic-jacketed steel cable, combined with a seawater return loop, it achieves simultaneous transmission of data and electrical power over a single insulated steel cable.

• Real-Time Deep-Sea Telemetry 

  Unlike traditional post-retrieval towed measurement methods, this module transmits deep-sea sensor data in real-time up to the deck unit. This allows immediate data evaluation and operational decision-making, significantly boosting measurement efficiency and mission success rate.

• Contactless Modular Maintenance

  The non-contact architecture allows sensor modules to be added, removed, replaced, or serviced individually on-demand. A single module failure will not disrupt the overall subsea cable array operation.

• High Efficiency & Reliable Transmission

  Delivers impressive inductive power transfer efficiency of ≥70% and a stable data transmission rate of no less than 1,200 bps, ensuring superior transmission reliability in harsh marine environments.
