Tank Explorer - in-service robotic bottom inspection
Tanks are designed and manufactured in many different variations for the safe storage of a range of products. We can inspect storage tanks containing high and low flashpoint products such as lube oil, silicone, glycol, water, acetone, benzene, naphtha, methanol, jet fuel, gasoline among others.
Tank floor corrosion. Let our Explorer get to the bottom of it.
Safe, trusted, certified. Entirely Intero.
Regular tank inspections are required for a number of reasons, including:
- License to operate
- Tank integrity assessment
- Maintenance planning
Our inspections are done according to industry standards, e.g. API-653, EEMUA 159, and use intrinsically safe equipment (UL, ATEX) where required. In addition, our tank inspections are fast and cost-effective and require no downtime or disruption to your business operations.
We provide tank inspections for:
- Petrochemical industries
- Water industries
- Nuclear industries
Intero Integrity Services’ storage tank inspections will ensure the safety, reliability and integrity of your storage tank, while providing more efficient operations.
We offer skilled personnel, a global reach and the best available equipment to ensure a high quality inspection solution you can trust.
Tank Explorer by Intero. The standard for your online tank inspection service.
Over 1000 storage tanks successfully inspected non man entry since 1997.
Tank Explorer - in-service robotic bottom inspection
Due to regulatory demand or internal Integrity reasons storage tanks have been taken out of service for inspections like tank bottom corrosion assessments and bottom settlement inspections. With Intero's ultrasonic (UT) Explorers this inspection can be performed during operation, it now means there is no longer any need to empty the tank. In this way you can significantly reduce costs of in-service inspections and the effects of downtime, while cleaning costs and (off-spec) product waste are reduced too.
Our robotic Tank Explorer provides inspection according to the API 653 standards and EEMUA 159, or customized to the customers need.
The intrinsically safe autonomous tank bottom explorer uses UT sensors to detect any variation in thickness of the bottom plate and can differentiate between product and soil side corrosion. Our sophisticated navigation system and camera’s assure that we can cover the full surface of your tank bottom or as required and can give you a view at your tank bottom (product permitting).
Tank bottom settlement measurements are commonly taken when the tank is out of service and empty. However, the same data set obtained from the robotic online tank floor corrosion inspection can also be used to assess the tank bottom settlement. This will not only provide a more accurate and a realistic settlement assessment with the product in the tank but also provide a full, high resolution settlement display of the tank bottom rather than the spot checks on selected locations using out of service inspection.
While your storage tank remains in-services, the Tank Explorer records:
1. UT tank bottom wall thickness
2. Video footage of the tank bottom
3. Tank bottom settlement survey
We are proud to show that our technology is an award winning one
Intero Integrity’s innovative robotic inspection solution have been recognized by the SPRINT Robotics collaborative as a preferred standard solution to be considered for the majority of storage tanks around the world.
API 653 CERTIFIED
The Intero Integrity approach to tank inspection is a well-recognized and trusted method throughout the industry today. Tank owners can significantly reduce the costs of performing API 653 inspections by not having to remove their tanks from service, and by being able to plan out-of-service periods.
The Intero Integrity robotic system is efficient and cost-effective while it:
- eliminates the high cost of tank downtime.
- does away with the need for temporary storage.
- saves you the cost of cleaning.
- minimizes waste disposal costs.
- cuts inspection time to days instead of weeks.
- avoids disruptions in plant operations, keeping revenue constant.
- reduces environmental risks such as spills and VOC release.
- improves safety by eliminating confined space entry and personnel exposure to hazardous chemicals.
Our high quality robotic equipment ensures constant, controlled and proven conditions for tank bottom inspections. Robotic equipment is safer than manual inspection, and is unaffected by working conditions. Its advanced, computer-based ultrasonic technique makes data collection more accurate.
Intero’s patented acoustic navigation system – equipped with navigation pingers on the robot and navigation transducers on the tank shell – is used to pinpoint the robot’s location. Using onboard UT transducers, developed with years of knowledge and expertise from our pipeline inspection services, the robot follows a predetermined digital inspection grid and can collect millions ultrasonic scans of the tank bottom in order to perform computerized data analysis. The robot is equipped with an onboard sonar system to detect objects in the tanks. When operating in clear fluids, we can equip the robot with HD cameras. The navigation allows us to reproduce our inspections in the future to determine corrosion rates with great accuracy.
Our robots can manoeuvre in tanks containing sludge of up to 30 centimeters (12 inches) in depth. We can also equip our robot with cleaning systems using spray nozzles and brushes. This way it simultaneously cleans and inspects the tank bottom, enhancing safety and reducing costs. Cleaning times may vary depending on sludge levels.
Safe and cost-effective
Inspections involving a human presence increase safety and environmental risks, and traditional tank bottom inspection technologies require tanks to be offline during inspection. They must be drained, cleaned, degassed and ventilated – all of which incur significant costs for owners. By using the Tank Explorers, the tank bottom inspection takes significantly less time, and is safer and more cost-effective.
Strong track record
We have been developing and deploying innovative online tank robotic inspection services for more than 20 years and has developed a strong track record. With a large fleet of robotic solutions we can choose the best solution for your needs. Through the years we have inspection more than 1000 storage tanks
Many clients worldwide are using our innovative robotic inspection solutions, benefiting from this cost effective and safe alternative, e.g. VOPAK, Shell, DOW, BASF, Exxon Mobile, Marathon Oil.
