ABERDEEN, UK– Nautronix has secured an order to supply its NASeBOP (emergency BOP acoustic control system) for installation on Rowan Companies’ two new ultra-deepwater drillships. The systems are scheduled for delivery in 2013.
The NASeBOP control system provides a method of backup control of BOP functions in the event of primary communication and control failure. At the heart of the system is Nautronix’ ADS² (acoustic digital spread spectrum) signaling technology.
The system consists of two subsea control units (SCU) connected to remote transducers. Each SCU is capable of controlling and monitoring up to eight functions. This includes control of an emergency disconnect sequence (EDS).
A 10-m (33-ft) cable allows remote transducers to be positioned away from the SCUs, thus reducing the risk of shading or multi-path effects caused by adjacent structures or subsea objects. Two SCUs provide system redundancy as each can be used independently for control and monitoring.
