Subsea Drilling Control Systems

Proserv has expanded its offering in Drilling Control System services with the addition of a subsea emergency acoustic control system (NASeBOP) for a Blowout Preventer should the primary control on the BOP be lost or cannot be reached safely.  The system is fully redundant including a complete emergency backup system with a key advantage of being able to monitor the BOP if an Emergency Disconnect Sequence (EDS) is executed.

The product offering complements Proserv’s topside equipment control system(s) service offering which focuses on performance optimization, reliability, economy and product support to extend the life of a rig.  And the product serves as an extension to Proserv’s service offering for BOP upgrades and maintenance programs in which Proserv’s Drilling Division built its reputation through fabrication and installation of fluid power control lines, medium and high pressure tubing, electrical, Gilmore Directional Control Valve product support and instrumentation integration on all styles of BOP control systems.

EXPERT VIEW
NASeBOP’s advanced coding technology which is optimised for long range, high integrity control and monitoring of subsea assets, ensures there is no interference from unwanted sources such as other acoustic noise or the environment.

NASeBOP

NASeBOP features multiple user interfaces, from a feature packed Master Station installed on the vessel to Portable Units for emergency control from a lifeboat. An Emergency Response System can be stored off the vessel as a backup system should all other methods of initiating an Emergency Disconnect Sequence (EDS) prove impossible.

At the heart of NASeBOP is ADS² (Acoustic Digital Spread Spectrum) signaling technology. The key advantage of ADS² is the advanced signaling technology which is optimized for long range, high integrity control and monitoring of subsea assets. This ensures there is no interference from unwanted sources such as other acoustic noise or the environment. The handshaking protocol used within the NASeBOP system maintains the highest level of system integrity and satisfies all current requirements of API 16D and 17E.
