As a major supplier of acoustic systems to the offshore oil and gas industry with over four decades of experience, we have in-depth knowledge of the subsea acoustic environment and can provide you with the only Acoustic BOP Control System that is fully API compliant and have been field-proven in the immediate proximity of a major subsea blowout.
Our proprietary Wideband digital acoustic signalling technology, built into every system, provides a two-way communication link that is highly robust and resistant to noise, multi-path effects and interference from other acoustic sources.
Dual SEMs (Subsea Electronics Modules) mounted on the BOP provides the interface to the client BOP, driving up to 12 pilot valve solenoids to operate the hydraulic functions. 12 pressure operated switches and 4 analogue sensors indicate the BOP’s internal status and the SEM can interface to BOPs from all major manufacturers.
Each SEM has a unique address and will only respond to commands that include this code. This allows several rigs to operate systems within acoustic range of one another without any interference. The probability of a false trigger event has been shown to be extremely remote, whilst the probability of operation on demand has been similarly shown to be very high.
