Acoustic control system for BOP operation

Contact us

The Acoustic Control System - ACS500 is designed for acoustic control of Blow Out Preventer - BOP and subsea production units. The subsea unit may control up to 16 different functions.

An advanced acoustic telemetry link, using either the latest technology, Direct Sequence Spread Spectrum, or upon request from operator: the traditionally used Frequency Shift Keying. This provides a reliable communication in noisy and reverberant offshore environment and maintains compatibility with new and existing topside control system.

Acoustic control system operating depths

The ACS500 system is delivered as medium frequency (MF) system and can be delivered for water depths down to 4000 meters (13000 feet).
