简介：NASMUX是一个针对海底防喷器设备进行全面控制的声波系统，该系统一改传统控制系统的复杂设备配置，利用声波来传送命令进行控制，从而增大了操作台的有效使用面积和操作成本。

NASMUX is an acoustic system providing full control for subsea Blow Out Preventer (BOP) equipment and offers an alternative to traditional multiplexed (MUX) control systems. NASMUX replaces the command, control and monitoring aspects of a control umbilical with an acoustic system which requires very little topside equipment. As a result, immediate benefits are realised, including: flexibility to transfer the system between rigs quickly and cheaply; increasing available deck space and reductions in handling and transportation costs.

NASMUX features include high function count, digital readbacks, analogue signals for information such as pressure readings, and several programmable sequences for single-command activation of sequences such as emergency disconnect. The system is a collaborative venture between Nautronix, Aberdeen, Scotland and Cameron Drilling Systems, Houston, Texas.

The underlying technology (Nautronix' proprietary Acoustic Digital Spread Spectrum signalling) has been proven, over ten years of successful subsea operations, as a highly reliable and extremely robust technology for addressing this kind of mission-critical requirement. This track record includes a previous Cameron - Nautronix collaboration for control of small-scale subsea isolation devices.

Nautronix holds the Intellectual Rights to the technology, but has an agreement with Cameron for exclusive use of the solution within the drilling arena.
