AUV gauges electrical potential of subsea pipelines offshore Japan
January 13, 2023, by Nadja Skopljak
Japan’s Kawasaki Heavy Industries and French energy major TotalEnergies
have completed a joint offshore verification test measuring the electrical potential of subsea pipelines during close-range inspections using an autonomous underwater vehicle (AUV).
The test was performed using what is said to be the world’s first AUV with a robot arm for subsea pipeline inspections,
SPICE (Subsea Precise Inspector with Close Eyes), in Japan, offshore Awaji Island, Hyogo Prefecture.
Kawasaki decided to launch a joint research project
proposed by TotalEnergies to integrate the French company’s electrical potential measurement technology
Light Touch Cathodic Protection (LTCP) with SPICE to make the AUV capable of measuring the electrical potential gradient of a pipeline allowing the detection of potential coating defects.
Starting in October 2020 and lasting through February 2021,
the basic design
was completed and integration simulations were performed.
Beginning in August 2021,
a more detailed design and modifications of SPICE were conducted to incorporate the LTCP.
According to Kawasaki,
these preparations made possible the verification test off Awaji Island from 30 August through 2 September, resulting in the successful measurement by LTCP integrated with SPICE of the electrical potential of pipelines.
First, for this offshore test,
simulated pipes and a corrosion protection system were placed on the seabed. SPICE performed the measurements using the robot arm
with its newly-integrated measurement device to check the pipelines’ state of protection against corrosion inferred by the measurement of the electrical potential.
The outcome suggests that
SPICE can achieve automation and reduce operational time in close-range subsea pipeline inspections currently performed by remotely operated vehicles (ROVs),
including measurement of electrical potential, the Japanese company concluded.
Kawasaki received an order back in 2021 from the UK’s Modus Subsea Services for the first commercial model of SPICE,
which will be an upgraded version of the one that was used for this verification test.
