‘Mote’-based wireless monitoring for BP

Emerson equips BP refinery with self-contained sensors and self-organizing data network.

BP and Emerson Process Management have developed what is claimed to be the world’s first intrinsically safe ‘mote-based’ wireless monitoring system. Motes are sensors with built-in power, memory and communications that record sensor data and broadcast it over a ‘self configuring’ wireless network. Wireless reduced sensor deployment costs by an order of magnitude. The system was developed to improve maintenance and safety at BP’s Washington State Cherry Point refinery.

Plant Web

Emerson launched its in-plant Smart Wireless last October in part to ‘unlock stranded diagnostics’ in legacy plants—acting as ‘eyes and ears’ to enhance plant performance. The in-plant wireless solution extends Emerson’s PlantWeb digital plant architecture and its wireless asset management solution (AMS). A 900 MHz Smart Wireless solution is already available in North America and a 2.4 GHz solution will launch in Europe and Asia early this year. BP awarded the Cherry Point team its Digital and Communication technology (DCT) award.


In a separate announcement, Emerson was awarded a $1.7 million contract by the Atlantic liquefied natural gas project in Trinidad where the AMS Suite Equipment Performance Monitor will be used to optimize throughput and rotating machinery operations on four LNG trains.
