- What is Subsea Internet of Things (SIoT)
Subsea Internet of Things:
is a network of smart wireless sensors
and devices configured to provide
actionable operational intelligence such
as performance, condition and diagnostic
information.
Subsea Internet of Things

5. What is the Subsea Internet of Things?
- Smart Devices
• Multi-parameter smart sensor
– Asset Integrity: Temp, UT, CP, Vibration, Crack
– Flow Assurance: Temp, Flow, Vibration
• Hybrid comms: wired/wireless
• Intelligent bandwidth management
– Local data processing  low data density
– Local process model correction  fog
computing
• Intelligent power management
– Local power generation

6. Reducing Offshore Costs
• Why are offshore costs so high?
– Low levels of automation - production and inspection
– High cost of intervention
– Over-design
– Low extraction efficiency
• How Subsea Internet of Things Drives down
Costs
– Increase production efficiency
– Reduce inspection costs
– Extend asset life
– Lower field extension costs
– Lower green field CAPEX/OPEX
