UTM Survey Services for Maritime and Industrial Assets. (A-Star Testing & Inspection – Leader in Integrity inspection, Condition Monitoring, Ultrasonic
Thickness Measurement and CVI & GVI Inspection Survey of Hull, Equipment & Piping)
Introduction:
Ultrasonic Thickness Measurement (UTM) surveys are essential for assessing the structural integrity and
safety of various maritime and industrial assets such as ships, rigs, offshore platforms, refineries, and
petrochemical plants. These surveys provide critical data on material thickness, corrosion rates, and
potential defects, enabling proactive maintenance and ensuring regulatory compliance. Here, we outline
the significance and scope of UTM surveys for different sectors and the comprehensive services offered.
Significance of UTM Surveys:
Safety Assurance: UTM surveys help identify areas likely to corrosion, erosion, or structural weakening,
reducing the risk of catastrophic failures and ensuring the safety of personnel and the environment.
Regulatory Compliance: Regulatory bodies mandate regular UTM surveys to ensure that assets meet
safety standards and structural integrity requirements.
Cost Efficiency: Early detection of corrosion or degradation through UTM surveys allows for timely
maintenance interventions, preventing costly repairs or replacements in the future.
Asset Longevity: Proactive maintenance based on UTM survey data extends the operational lifespan of
assets, maximizing their productivity and return on investment.
Scope of UTM Survey Services:
Maritime Assets:
Ships: Comprehensive UTM surveys assess hull thickness, bulkheads, tanks, and structural components
to detect corrosion, erosion, or mechanical damage.
Offshore Rigs and Platforms: Surveys cover platform legs, braces, risers, pipelines, and critical
components exposed to harsh marine environments.
Floating Structures: UTM surveys evaluate the hull, pontoons, mooring systems, and other submerged
components for integrity and corrosion monitoring.
Industrial Facilities:
Refineries: Surveys focus on pipelines, storage tanks, pressure vessels, and process equipment to detect
corrosion, erosion, and material degradation.
Petrochemical Plants: UTM surveys assess equipment such as reactors, heat exchangers, distillation
columns, and storage facilities for structural integrity and safety.
Power Plants: Surveys are conducted on boilers, turbines, condensers, and piping systems to ensure
reliability and compliance with regulatory standards.
Comprehensive UTM Survey Services:
Inspection Planning and Scheduling: Tailored survey plans are developed based on asset type, size,
operational conditions, and regulatory requirements.
Advanced Ultrasonic Testing: State-of-the-art equipment and techniques are employed to accurately
measure material thickness and detect defects with high precision.
Data Analysis and Reporting: Survey data is analyzed by experienced technicians and engineers to assess
asset condition, corrosion rates, and remaining service life. Detailed reports are provided, including
recommendations for maintenance and remedial actions.
Regulatory Compliance Support: Assistance is offered in interpreting regulatory requirements and
ensuring compliance with applicable standards and guidelines.
Continuous Monitoring Solutions: Long-term monitoring programs are designed to track changes in
material thickness and degradation rates, enabling predictive maintenance and risk management.
Conclusion:
Ultrasonic Thickness Measurement (UTM) surveys play a crucial role in maintaining the safety, reliability,
and efficiency of maritime and industrial assets. By offering comprehensive survey services tailored to
the unique needs of each sector, including ships, rigs, offshore platforms, refineries, and petrochemical
plants, we ensure that clients can effectively manage asset integrity, meet regulatory obligations, and
optimize lifecycle costs. Our commitment to quality, innovation, and technical expertise ensures that
assets remain operational, safe, and productive throughout their service life.
