The Importance of Asset Integrity Management (AIM)

AIM ensures operational safety, minimises unplanned downtime and reduces the risk of failures, making it critical to the long-term success of industrial operations.

AIM involves maintaining the functionality of equipment and infrastructure over its lifecycle with the aim of minimising risk, preventing failure, and ensuring compliance with industry standards and government regulations. Scheduled AIM inspections are essential for ensuring the safety, reliability, and longevity of industrial assets, particularly in the oil and gas, petrochemical, power generation and mining industries. 

3PI are New Zealand’s AIM specialists

3PI has a track record of preventing major issues, such as identifying severe corrosion on a wharf line that could have led to an oil spill, which saved our clients from costly repairs and environmental damage.

We provide expert guidance on API codes, WorkSafe, and industry best practices, ensuring optimal solutions for our clients. Safety is our top priority, reflected in our strict Health and Safety policies.

Our AIM inspections cover a wide range of assets and equipment, including:

  • Pressure Vessels and Boilers

  • Pipelines and Piping Systems

  • Storage Tanks

  • Offshore Platforms

  • Refineries and Petrochemical Plants

  • Structural Components

  • Welding inspection

Storage Tank Inspection & Integrity Assessment

Our experienced inspectors and engineers provide comprehensive integrity assessments for Aboveground Storage Tanks (ASTs), combining internationally recognised inspection practices with advanced inspection technologies.

Our capabilities include:

  • On-stream Tank Inspections

  • Off-stream Tank Inspections

  • Tank Floor and Annular Plate Corrosion Mapping by Advanced NDT

  • Shell, Roof and Structural Assessments

  • Corrosion and Remaining Life Evaluations

  • Tank Settlement and Foundation Assessments

  • Repair, Alteration and Reconstruction Assessments

  • Inspection Interval Determination

  • Engineering, Risk Based Inspections (RBI) and Fitness-for-Service Assessments

Advanced NDT & Inspection Technologies

Accurate integrity decisions depend on reliable inspection data. 3PI combines conventional inspection methods with advanced NDT and remote inspection technologies to provide a comprehensive understanding of tank condition.

Our inspection capabilities include:

  • Magnetic Flux Leakage (MFL) floor scanning

  • Phase Array Ultrasonic (PAUT) and Ultrasonic Thickness Testing (UT)

  • EMAT

  • Automated and Robotic inspection systems (UT wall crawler, 4K Camera wall crawler)

  • RX and Industrial Radiography (Real Time, Computerised) and Weld inspection (Leak Testing, SFT, Vacuum Box)

  • Remote inspection technologies (Aerial Drones and Underwater ROV’s for remote visual inspections)

  • Laser and 3D Scanning.

These technologies can also help reduce personnel exposure, confined-space entry and operational disruption where appropriate.

From Inspection Data to Integrity Decisions

Finding corrosion is only part of the process. The real value of Asset Integrity Management comes from understanding what the inspection results mean for the future operation of the asset.

3PI integrates inspection findings with engineering assessment to support:

  • Remaining life evaluation

  • Corrosion rate assessment

  • Inspection planning and optimisation

  • Repair and maintenance prioritisation

  • Fitness-for-service decisions

  • Risk-based integrity planning

  • Life-extension strategies

  • Long-term asset integrity management

This integrated approach helps asset owners move from reactive maintenance towards planned, risk-informed asset management.

Supporting the Complete Tank Lifecycle

DESIGN & CONSTRUCTION → COMMISSIONING → CERTIFICATION → OPERATION → INSPECTION → MAINTENANCE & REPAIR → LIFE EXTENSION → DECOMMISSIONING

3PI provides inspection and engineering support throughout each stage, helping ensure that integrity considerations remain part of the asset management strategy from initial design through to retirement.

Risk Prioritised Inspections

The goal of RBI is to focus resources on areas of greatest risk to enhance safety, minimise downtime and reduce inspection costs. We specialise in RBI inspections in the oil and gas, petrochemical, power generation, and other process industries. 

The scope of RBI's is often broad, encompassing both critical equipment and less critical components, based on risk analysis, optimising inspection schedules and ensuring reliability.

  • Pressure Vessels

  • Heat Exchangers

  • Pipelines and Piping Systems

  • Storage Tanks

  • Furnaces, Boilers and Reactors

  • Rotating Equipment like Pumps and Compressors

  • Structural Components
