MTRC Airport Express: Smart Power System
We won a tender of MTRC in 2013 to provide a Fibre Optic Sensing system to monitor the operations conditions of the Lantau Airport Railway 33KV Power Cables
The 3.5 km power cables are used to supply electricity to the Airport Express trains
The Fibre Optic system provides Early Stage
Warning on potential power system problems

Looping of fibre optic cables at each end of joint
Thermal Property of Power Cable
Temperature profile of an underground cable hinges to the following factors [reference 1]: Load (% of rated load) profile Cross-section areas of conductors Condition of burial condition (direct buried or in conduit) Surrounding soil (composition, humidity, thermal resistivity) Nearby heat /cool source Age of cable (increasing loss tangent) Condition of cable joint (changes in resistance) Condition of cable insulation (changes in resistance) Transient cable fault
Temperature of Power Cable
The relation between load and temperature of an underground cable is well documented in many reports including IEEE’s [reference 1] and Neher McGrath {equation:
temperature rise vs current load (% or rated current)
Reference 1: IEEE Recommended Practice for Protection and Coordination of Industrial and Commercial Systems. ANSI/ IEEE Stand. 242, 1986. p.344

Power cables: Neher-MacGrath; IEC 60287
IEEE temperature rise vs current relation Neher – McGrath equation
Close co-relations between power cable loading and temperature
Effect of insulation of power cable and modelling
Power cable has layers of insulation
These layers are made of different materials that have various thermal properties
A RC circuit model is used to simulate the thermal effect of each layer
Smart Gas & Oil Pipelines
Corrosion Monitoring
Status: R&D Stage
Pipelines Oil & gas industries deploy substantial amount of infrastructure
Failure of these infrastructure can cause catastrophic losses and
adverse environmental effects
BP oil spill in April 2010 killed 11 people and BP was fined US$20 billion
There are more than 3.5 million km of oil & gas pipeline in 120 countries
There have been, on average, more than 300 significant pipeline failures per year [ref. KPMG Global Energy Institue]
Corrosion accounts for over 30% of pipeline failure
Present method of corrosion involves extensive manual
operations and have inherent operations limitations
Corrosion
External Force
Other
CAUSES OF PIPELINE FAILURES
Extensive pipeline network in Asia
Thousands of wildlife were destroyed because of BP oil spill
Objectives of Development
To identify a solution to monitor and quantitatively assess the corrosion situation of pipelines. The solution should meet the following requirements: Self-operable. Once the solution is set-up, it will operate independently and requires no/
minimum manual operation Full-length, full-area monitoring. The solution can monitor the full length of pipelines and cover
both exterior and interior surfaces Quantitative assessment. The solution can provide quantitative results to facilitate “fitness-for-
purpose” decision Monitor on a 24x7 basis Remote accessible and can be fully integrated with other external control systems Commercially economical Mass-producible Further Patent the solution and all associated IP
Technology Options 1. Ultrasonic
2. Imaging
An ultrasonic transducer is coupled to the pipeline and an ultrasonic wave is transmitted into the pipeline.
The reflected signal is then captured and analysed
This technology option is based on changes in the pipeline surface texture at the corrosion spot.
The captured image will then be processed using clustering algorithm technique
Technology Options
3. Electro Magnetic Wave
This method involves propagating a guided electromagnetic wave (EM wave) in the walls of the pipes and look for reflections from the corrosion spots (defects). The reflected wave is then received and analysed. Issues of importance are frequency of the EM wave and establishment of the refection pattern and the intensity of corrosion
Methodology The R&D is being carried out in collaboration with Department of Physics (Professor Prof. Aleksandra B.
Djurišić), HK University.
The Project has been granted approval from Innovation and Technology Commission on “R&D Cash Rebate Scheme” [Reference CRP/040/16 Dated 29 April 2016]
A five-stage approach:
Stage Deliverables
Literature research Synopsis of the documents & papers researched with highlights on the technologies used to detect corrosion and their respective limitations
Analyse, identify and design Recommendation on two to three feasible technology options that will meet the requirements of the target solutions. Prioritise the options in terms of their respective degree of viability
Prototype design, construction and laboratory testing Two most viable options are selected for prototypes construction
Analysis of results and review The test results and findings are analysed and conclusions are drawn
Field testing The prototype is applied to an operational pipeline for field testing
