SONARDYNE - Acoustic Release and Transponder - RT6-1000

Operational overview and field deployment

Instrument role in acoustic release and subsea positioning systems

SONARDYNE Acoustic Release and Transponder RT6-1000 is designed for controlled release and recovery of subsea equipment in offshore and deep-water environments. It combines acoustic activation with transponder functionality and attitude sensing for improved operational control.

Measurement and functional capabilities

This system enables remote acoustic release of moored or seabed-deployed equipment and includes an inclinometer to monitor orientation during deployment. It is commonly used in applications requiring precise recovery operations and reliable positioning feedback under load.

Operational environment

The system is designed for offshore and deep-water use with a depth rating of up to 1,000 meters. It is suitable for environments where long-duration deployments and reliable acoustic communication are required.

System integration role

Within a subsea deployment architecture, it functions as a critical release and tracking component integrated into moorings, seabed frames, or instrument packages. It supports tandem configurations to increase working load capacity depending on deployment requirements.

Deployment usage

Deployment involves integrating the unit into the mooring or instrument system prior to lowering it to depth. After the measurement campaign, an acoustic command is transmitted from the surface vessel to trigger release and initiate recovery.

Typical users

It is commonly used by oceanographic institutes, offshore survey companies, and marine engineering teams conducting deep-water mooring deployments, subsea instrumentation campaigns, and recovery operations.
