TankRob - project objectives

 News from 2016-11-08

It is estimated that 20% of storage tank accidents are caused by cracks or raptures on the tank structure.

The majority of the bulk liquids stored in these tanks include crude oil and derived products which are extremely hazardous to the environment, for example, a spill of only one gallon of oil can contaminate a million gallons of water.



On the other hand, such storage tank NDT inspection process is very costly, long cycle, and harmful for both environment and human inspectors. Currently, there is no inspection solution allowing for low-cost and 100% surface tank inspection.

The above described circumstances combined with the rapid advancement of robotic technology in the last years give rise to a unique opportunity; that of eliminating the need for human entry in tanks during inspection thereby significantly reducing the downtime-related costs to the end-users and eliminating the threats to human health.



Our goal is to capitalise on previous outstanding work and commercialise TankRob, a highly innovative robotic crawler that is capable of semi-autonomously inspecting storage tank steel plates using ultrasound technology.

A prototype of the system has already been built and tested and it has shown tremendous potential to meet the need for in-service steel tank inspection.



Our primary target customers will be large storage tank operators and SME NDT service providers initially in European, Asian and Middle-eastern markets.

It is aimed to grow our businesses by €202.86m in gross sales resulting €39.47m of profit over the 10 years after our product’s market launch, translating to a total amount of 897 new jobs.


Project Objectives

  • Design optimisation to allow for certification for use in explosive environments while minimising the manufacturing costs:

The system’s mechanical and hardware design should be optimised with respect to manufacturability and certifiability while maintaining its original size of 300mm. This will enable TankRob to be able to pass through trapdoors with diameter as small as 300mm which will make it suitable for inspecting 90% of storage tanks.

  • Control and ultrasound imaging algorithm fine-tuning and GUI implementation:

The algorithms for the system’s motion control and ultrasound scanning should be fine-tuned with respect to the new design and user-friendly Graphical User Interface will be implemented to facilitate ease of use.

  • Certification of TankRob:

TankRob’s key value proposition is its ability to perform in-service tank inspection which enables tank operators to achieve great cost savings by avoiding large downtimes associated with tank cleaning and venting. This feature will be realised by obtaining the Ex marking which is necessary to prove that the system can be safely used within flammable liquids such as crude oil.

  • Validation and qualification of TankRob in operational environment:

The system’s performance will have to be validated in operational environment in order to prove its value to the end-users. These trials will take place in an oil tank in Tüpras (largest Turkish tank operator) facilities in Turkey according to an agreement already in place.

  • Establishment of TankRob’s distribution network:

The consortium should have reached a formal agreement with 3 distribution agents in the Baltic Region, China and Middle East where the largest oil tank farms reside.
