PRESSURE VESSEL IN-SERVICE INSPECTION (ISI)

In Australia and New Zealand, the in-service inspection of pressure vessels plays a crucial role in ensuring the safety and integrity of industrial facilities. The in-service inspection process is vital for identifying and addressing potential issues such as corrosion, material degradation, and fatigue that may compromise the structural integrity of these vessels over time. Adhering to rigorous inspection protocols helps prevent catastrophic failures, protects human lives, and safeguards the environment. The regulatory framework for pressure vessel inspections is guided by AS/NZS 3788:2006 standards, which provide guidelines for in-service inspection and maintenance of pressure equipment. Compliance with these codes ensures that pressure vessels meet the required safety standards and are regularly monitored to mitigate risks associated with their operation.

Vertech is NATA-accredited and has a wealth of in-service inspection knowledge. Our subject matter experts (SMEs) are trained and experienced in applying Australian and New Zealand in-service standards such as AS3788, AS4343 and AS1210. Our team of SMEs are also qualified and experienced in American Petroleum Institute (API) codes such as API 510, API 579, ASME B16.5, ASME VII and API 653 (Tanks).

The worker's back is to the camera, and they appear to be examining or adjusting a section of the pipe with visible corrosion and rust. The setting is industrial, with metal structures surrounding the area and natural light from the right, indicating that the location might be an outdoor or semi-outdoor facility. Safety and maintenance work is suggested by the worker's presence and the equipment's condition.

PIPING SYSTEM IN-SERVICE INSPECTION

Inspecting piping systems is paramount to ensure industrial facilities’ safe and reliable operation across various sectors. Piping systems play a critical role in transporting fluids and gases, and regular inspections are crucial for identifying potential issues that could compromise their integrity. These inspections are guided by standards such as ASME B31.3 and ASME B31. Range, AS 4041-2006, API 570, and AS/NZS3788 provide comprehensive guidelines for piping systems’ design, construction, and maintenance.

The in-service inspection of piping systems encompasses a range of methodologies to address diverse challenges. Vertech, as a leading provider of inspection services, recognises the significance of these inspection processes for piping and pressure systems, so our qualified inspectors employ advanced technologies and proven methodologies to assess the condition of piping systems comprehensively. By prioritising the in-service inspection of piping systems, Vertech aims to enhance industrial facilities’ reliability, safety, and compliance throughout Australia and New Zealand, offering clients peace of mind in the face of complex operational challenges.

INTEGRITY ENGINEERING SERVICES

Integrity engineering and management are pivotal in ensuring the longevity, safety, and reliability of industrial assets. These practices involve a comprehensive approach to evaluating, monitoring and maintaining the structural and functional integrity of equipment, pipelines, and facilities in sectors such as oil and gas, petrochemicals, and power generation. The benefits of implementing a robust integrity management system are multi-fold. Firstly, it significantly reduces the risk of equipment failure and unplanned downtime, enhancing operational efficiency. Secondly, it promotes safety by identifying potential hazards and vulnerabilities, allowing for timely corrective actions. Thirdly, a proactive approach to integrity engineering minimises environmental impact, ensuring compliance with regulatory standards. In essence, integrity engineering is not merely a technical necessity but a strategic imperative for organisations committed to long-term success.

Entrusting the management of integrity engineering to experienced inspection companies like Vertech and Sonomatic amplifies these benefits further. Seasoned inspection professionals bring a wealth of expertise, utilising cutting-edge technologies and methodologies to conduct thorough assessments. Their proactive approach helps identify and address potential issues before they escalate, preventing costly repairs and downtime. Moreover, established inspection companies often possess a track record of successful projects, instilling confidence in their clients regarding the reliability of their services. By partnering with us, our clients can focus on their core operations with the assurance that their assets are in capable hands, adhering to the highest standards of integrity and safety.

A graph overlay indicates the relationship between pipe thickness and corrosion rate, with coloured lines representing different rates. The visual metaphor suggests the importance of pipe thickness in preventing corrosion, likely in the context of oil and gas industry infrastructure.

UN-MANNED IN-SERVICE INSPECTION

Vertech group has led the charge in heavily reducing and eventually removing manned inspections through improved methods such as Risk Based Inspection (RBI) and Non-Intrusive Inspection (NII), and improved technologies such as Remote Digital Visual Inspection (RDVI), Robotic Crawlers, pipeline crawlers, Unmanned Aerial Vehicles (UAVs), and Mini- and Micro-ROVs.

RDVI uses remote digital systems such as robots or crawlers to inspect and assess difficult-to-access areas internally without needing Confined Space Entry (CSE). RDVI is effective for Foreign Object Search and Retrieval (FOSAR), condition and process efficiency assessments.

Vertech offers the latest generation RDVI systems and robots alongside the most experienced people in the Asia Pacific region to ensure the best-in-class outcome and safety excellence for all projects.

Vertech has class accreditation with the International Association of Classification Societies (IACS) and is a recognised American Bureau of Shipping (ABS) member for ‘Remote Inspection Techniques: UAV Inspection’. Combined with marine surveyors, ACIP, or API inspectors, our CASA-accredited pilots can complete safe, efficient, cost-effective inspections of processes, plants, or structures without needing manned alternatives such as rope access or CSE.

This cutting-edge robotic scanner is designed to perform inspections without manned entry, significantly enhancing safety by minimising the risks associated with confined space operations. It can perform remote operations, steering, and full rotation on its axis, producing data contributing to statistical analysis for non-invasive inspection justifications.
