SONARDYNE 7967 - LRT Surface Control Unit (SCU)

Operational overview and field deployment

Instrument role in acoustic release command and control systems

SONARDYNE 7967 LRT Surface Control Unit is designed as a command and programming interface for subsea acoustic transponders and Lightweight Release Transponders (LRT). It is used to configure, operate, and trigger underwater release and positioning systems.

Functional usage context

This unit enables surface-based communication with underwater transponders, allowing operators to program mission parameters, send acoustic commands, and manage release operations. It is a key interface for controlling subsea acoustic equipment during deployment and recovery phases.

Operational environment

The system is designed for use on vessels or offshore platforms in marine environments. It supports operational workflows in coastal and offshore missions where reliable acoustic command of subsea devices is required.

System integration role

Within a subsea acoustic system, it functions as the surface control interface linking operators to underwater transponders and release devices. It is typically used alongside USBL systems, moorings, and seabed instruments as part of a complete deployment and recovery setup.

Deployment usage

Deployment involves setting up the control unit on deck, configuring compatible transponders or release devices, and establishing acoustic communication links. It is then used throughout the mission to manage device behavior and trigger release operations when required.

Typical users

It is commonly used by offshore survey teams, oceanographic institutes, and marine engineering organizations conducting subsea instrumentation deployments, acoustic release operations, and recovery missions.
