The Subsea Internet of Things describes a network of smart wireless sensors and devices configured to provide performance, condition and diagnostic information. Underwater wireless-based communications systems are a cost-effective vehicle for controlling remote subsea oil and gas assets. Flow, temperature and pressure data is required to manage production while crack detection, vibration, fatigue, leakage, cathodic protection (CP) and pipe wall thickness measurements must be taken routinely to ensure structural integrity. Using bespoke sensors connected to intelligent underwater modems, these remote devices supply the necessary data to the surface-based centralised  distributed control system on demand, either directly through the water or alternatively, harvested by diver/robotic vehicle. In the same way that the Internet of things explores the ability of intelligent devices to intercommunicate, the Subsea Internet of Things extends this facility to the underwater community. Making these intelligent control decisions at a local level obviates the need for centralised control. The output of one remote sensor can directly provide input for another nearby. Depending on local conditions, for example, intelligent sensors can decide their own sampling rate. The remote automation reduces costs and increases reliability by optimising the flow of information, asset performance and  energy efficiency.
