TECHNICAL OVERVIEW

Industrial storage tanks operate under demanding service conditions that expose steel surfaces and structural components to corrosion, erosion, fatigue, mechanical stress, environmental degradation and process-related damage. Without regular inspection, these deterioration mechanisms may remain undetected until they affect operational reliability or require costly repairs.

Traditional inspection methods frequently require tanks to be emptied, cleaned and entered by inspection personnel. While conventional approaches remain necessary for many inspection scopes, advances in robotic inspection technologies now enable many visual and non-destructive examination activities to be performed remotely, reducing personnel exposure while improving inspection efficiency.

Industrial Robotic Tank Inspection combines remotely operated robotic platforms, advanced imaging systems, ultrasonic measurement technologies and digital data collection tools to evaluate tank condition with greater consistency and repeatability. These systems can access large areas of tank floors, shells, roofs and other internal surfaces while transmitting real-time inspection data to engineers for evaluation.

Inspection findings contribute to a broader asset integrity programme by providing information that supports:

Rather than relying solely on periodic visual observations, operators gain objective condition data that supports informed engineering decisions throughout the operating life of the asset.

WHY INDUSTRIAL ROBOTIC TANK INSPECTION MATTERS

Modern industrial facilities manage increasingly complex assets under demanding production schedules and stringent safety expectations. Inspection programmes must therefore deliver accurate information while minimising operational disruption and reducing unnecessary risk.

Robotic inspection addresses these objectives by enabling high-quality condition assessment without exposing inspection personnel to avoidable hazards during every stage of the inspection process.

A well-executed robotic inspection programme can help organisations:

Improve Personnel Safety

Reducing confined space entry wherever inspection scope permits helps minimise exposure to atmospheric hazards, slips, falls and other risks associated with manual internal inspections.

Enhance Inspection Coverage

Robotic systems can systematically scan large tank surfaces while maintaining consistent inspection paths that improve repeatability and documentation.

Detect Early Signs of Deterioration

Early identification of corrosion, coating breakdown, pitting, cracking indications, deformation or other anomalies allows maintenance activities to be scheduled before damage progresses.

Support Asset Integrity Programmes

Inspection findings become valuable inputs for integrity assessments, engineering evaluations, maintenance planning and risk-based inspection strategies.

Improve Shutdown Planning

Reliable inspection data enables maintenance teams to define repair scope, estimate required resources and optimise shutdown schedules with greater confidence.

Strengthen Regulatory Readiness

Documented inspection records support compliance activities and provide traceable evidence of asset condition in accordance with applicable project requirements and recognised industry practices.

Reduce Lifecycle Costs

Condition-based maintenance helps avoid unnecessary repairs while identifying developing defects before they require extensive corrective work or unplanned outages.

INDUSTRY CHALLENGES

Storage tanks rarely deteriorate uniformly. Environmental conditions, product characteristics, operating temperatures, water accumulation, microbiological activity and coating performance all influence how damage develops over time.

As a result, inspection programmes must be capable of identifying both widespread degradation and highly localised defects that could affect asset reliability.

Common challenges encountered during industrial tank inspection include:

Corrosion Hidden Beneath Coatings

Protective coatings may conceal underlying corrosion until deterioration becomes extensive. Inspection programmes often combine visual assessment with thickness measurements and coating evaluations to determine the true condition of steel substrates.

Floor Plate Corrosion

Tank bottoms are particularly vulnerable to corrosion resulting from water accumulation, microbial activity, settlement effects and product contamination. Robotic floor scanning technologies assist in identifying thickness loss and localised deterioration across extensive floor areas.

Shell Deformation

Settlement, overloading, thermal cycling and long-term operational stresses may produce distortion within tank shells. Early identification supports engineering assessment before structural concerns become more significant.

Difficult Access Areas

Roof structures, floating roofs, elevated shell sections and confined internal spaces can present access limitations for conventional inspection methods. Robotic platforms improve accessibility while reducing reliance on manual access methods where appropriate.

Inspection During Shutdown Constraints

Shutdown schedules are often compressed, requiring inspection teams to collect high-quality condition data within limited timeframes. Robotic inspection technologies can improve inspection efficiency while maintaining comprehensive documentation.

Large Asset Portfolios

Operators managing multiple storage tanks require consistent inspection methodologies that generate comparable data across facilities, enabling more effective maintenance prioritisation and long-term asset integrity planning.

By addressing these operational challenges with structured inspection methodologies and robotic technologies, Preshe Integrated Services Ltd supports clients in making timely, evidence-based decisions that protect asset performance, enhance safety and optimise maintenance investments.

Lower Long-Term Maintenance Costs

Early detection of deterioration enables planned maintenance rather than reactive repairs.

This helps organisations:

Stronger Digital Asset Management

Digital inspection records create a valuable historical database that supports long-term asset management.

Over successive inspection cycles, this information enables engineers to monitor deterioration trends, evaluate maintenance effectiveness and make more informed decisions regarding repair, replacement and life extension strategies.

Industrial Robotic Tank Inspection therefore becomes more than a periodic inspection activity. It becomes an integral part of a data-driven asset integrity programme that supports safer operations, improved reliability and sustainable lifecycle management.

Asset Integrity and Risk-Based Inspection

Industrial storage tanks represent long-term capital assets that must continue to operate safely, reliably and efficiently throughout their design life and, where appropriate, beyond it. Achieving this objective requires more than periodic inspections. It requires an integrated Asset Integrity Management (AIM) approach that combines condition monitoring, engineering evaluation, maintenance planning and continuous improvement.

Industrial Robotic Tank Inspection provides the high-quality condition data that forms the foundation of this process.

At Preshe Integrated Services Ltd, robotic inspection is positioned as an enabling technology within a broader asset integrity strategy. The information collected during inspections supports engineering teams in understanding the current condition of storage assets, identifying degradation mechanisms and making informed decisions regarding maintenance, repair and future inspection intervals.

Supporting Asset Integrity Management

An effective Asset Integrity Management programme seeks to ensure that assets remain fit for their intended service throughout their operational life while managing safety, environmental and business risks.

Robotic tank inspection contributes to this objective by providing reliable information on:

When integrated with maintenance records, operational history and engineering analysis, inspection findings become valuable decision-making tools for plant owners and operators.

Risk-Based Inspection (RBI) Support

Many industrial organisations have adopted Risk-Based Inspection methodologies to optimise inspection intervals and maintenance resources.

Rather than applying the same inspection frequency to every asset, RBI evaluates both the probability of failure and the potential consequences of failure to determine inspection priorities.

Robotic inspection provides the condition data necessary to support these evaluations by helping engineers:

Identify active corrosion mechanisms
Quantify deterioration rates
Detect localised defects
Monitor changes between inspection intervals
Validate previous inspection findings
Improve confidence in integrity assessments

Inspection data generated through robotic technologies can complement Risk-Based Inspection programmes developed in accordance with recognised practices such as API RP 580 and API RP 581, subject to client requirements and engineering review.

Supporting Remaining Life Assessments

One of the primary objectives of any inspection programme is determining how long an asset can continue to operate safely under its intended service conditions.

Inspection findings contribute to remaining life assessments by providing information on:

These assessments assist engineering teams in evaluating future maintenance requirements, repair priorities and replacement planning.

Remaining life evaluations should always be performed by competent engineering personnel using applicable engineering methodologies, project requirements and recognised industry practices.

Fitness-for-Service Support

Not every identified defect requires immediate repair or replacement.

Engineering evaluations often determine whether an asset remains suitable for continued operation while corrective actions are planned.

Inspection findings may support Fitness-for-Service (FFS) assessments by providing information concerning:

Where Fitness-for-Service evaluations are required, they should be completed using appropriate engineering procedures, recognised industry guidance and client specifications.

Corrosion Monitoring Programmes

Corrosion management is most effective when deterioration is monitored over time rather than assessed as isolated inspection events.

Periodic robotic inspections help establish measurable trends by comparing inspection results from successive inspection campaigns.

Trend analysis may identify:

Accelerating corrosion rates
Stable corrosion behaviour
Coating system performance
Effectiveness of previous repairs
Emerging deterioration mechanisms
Areas requiring increased monitoring

This historical perspective enables maintenance resources to be directed where they provide the greatest operational benefit.

Supporting Shutdown Planning

Planned shutdowns present valuable opportunities to inspect, repair and maintain critical assets.

Reliable inspection data enables project teams to define work scopes before shutdown activities begin.

Benefits include:

Rather than discovering defects during shutdown activities, facility owners can enter maintenance periods with a clearer understanding of asset condition and repair priorities.

Improving Long-Term Asset Reliability

Storage tank failures rarely result from a single event. More commonly, they develop through gradual deterioration that progresses over many years.

Routine robotic inspections help organisations identify these changes before they affect operational performance.

This proactive approach supports:

Improved operational reliability
Fewer unplanned outages
Better maintenance forecasting
Reduced emergency repairs
Extended equipment service life
Improved capital planning
Greater confidence in asset condition

For organisations managing multiple facilities or extensive tank farms, consistent inspection methodologies also improve asset benchmarking and portfolio-wide integrity management.

Health, Safety and Environmental Commitment

Health, Safety and Environmental (HSE) performance remains a fundamental consideration throughout every stage of an industrial inspection project.

Industrial tank inspections often involve confined spaces, elevated work areas, heavy equipment, hazardous atmospheres and potentially flammable products. Robotic inspection technologies help reduce exposure to these hazards by allowing many inspection activities to be completed remotely where practical and appropriate.

Preshe Integrated Services Ltd plans every inspection activity with the objective of protecting personnel, client operations, surrounding communities and the environment.

Reducing Confined Space Entry

Confined space entry remains one of the highest-risk activities associated with traditional internal tank inspections.
