Distributed Sensing DTS and DTSS Technology

Advantages of DTS and DTSS

• Fully distributed data greatly increase information and reduces uncertainty
  
  
• Sensor is made from standard optical fibre - cost effective
  
  
• Immune to shock/vibration and electromagnetic interference
  
  
• No electronics or moving parts in monitoring zones
  
  
• Inherently high reliability (sensor design life of 25 years +)
  
  
• High temperature performance 700°C
  
  
• Extremely small for access into space restricted areas (e.g. ducts, oil wells, pipes ...)

Benefits of DTS and DTSS

• Low cost per sensor
  
  The sensor is made from standard telecoms fibre, which means costs per sensor can be less than $3 per measurement point.
  
  
• Low installation costs
  
  Measurements are provided along the entire length of the cable, meaning less planning is required with regards to planning the location of each sensor.
  
  
• Low maintenance costs
  
  Fibre optics have no moving parts and cables typically have 25 year design lives, resulting that once the cable is installed, there are very low maintenance costs.

Applications

Oil and Gas Monitoring Monitor flow of production well, injection in water injection well, motors and sand screen integrity	Fire Detection How it works Real-time monitor and precisely detect location of a fire in buildings, tunnels and other high-risk locations
Subsea Flowline Flow Assurance Achieve real flow assurance - react to real problems instead of theoretical prediction	Structural Monitoring Real-time monitor all parts of a structure for early detection of overloading or failure
Process Monitoring Optimise production and reduce chemical injection by understanding platform process in detail	Umbilical Monitoring Monitor overheating in coiled umbilicals, know strain in umbilical and avoid breakages
Dam Safety Monitor temperature and strain to evaluate integrity of dam structure	Building Temperature Control Monitor and optimise temperature of all parts of building and hence energy use
Power Line Integrity Optimise current loading of power cables, detect hotspots and monitor cable sag	Pipeline Integrity Detect leaks and blockages quickly
