In-Service Inspection (ISI)

All engineered equipment has a finite life cycle and deteriorates over time with use. Vertech provides comprehensive in-service inspection services across a range of industries to assist our clients with their asset integrity management.

We actively reduce risk, reduce cost and ensure the safety of people, operations and assets in a potentially dangerous environment. Vertech’s knowledge and experienced inspectors ensure industry compliance with code, statutory regulations and legislative requirements.

Pressure Vessel In-Service Inspection (ISI)

In-Service Inspection (ISI) is essential to the safe and reliable operation of pressure vessels and pressure piping systems. Legislation such as AS/NZS 3788 requires that ISI of pressure equipment begins immediately after baseline inspections and the commissioning of pressure vessels for operation and includes the inspection of pressure vessels, boilers, and certain classes of pressure pipe systems that may interconnect items of the pressure plant. Pressure vessel inspection is performed to ensure the safety and integrity of pressure vessels.

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 standards 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 570, API 579, API 653 and ASME codes ASME B31.3, ASME B16.5.

Integrity Engineering Services

Vertech can assist clients to manage their assets by applying best practice engineering principles to develop bespoke solutions. From high-level strategies through to detailed engineering analysis, inspection planning and implementation, we can help achieve optimal life cycle cost, quality and profitability.

Across the industry, it is essential that plant and equipment are maintained in good condition as the failure of a component can have safety, financial, and environmental costs. Vertech offers a wide range of asset integrity management services across a diversity of plant asset types, enabling our frontline experienced inspectors to provide a best-in-class service and the right data required.

Manned In-Service Inspection Services

Vertech have been carrying out intrusive inspections of pressure vessel equipment for plant operators and assets across Australia and New Zealand since its inception. All our statutory pressure equipment inspectors are well trained in in-service inspection with either AICIP services and/or API in-service inspection certification qualifications.

Our in-service pressure vessel equipment inspectors hold complementary certification qualifications in NDT (Non-Destructive Testing), Confined Space Entry (CSE) and IRATA rope access as a minimum. They are well versed in the controls required for safe access and egress of pressure vessels and confined spaces.

Our manned in-service inspection services include:


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 Areal Vehicles (UAVs), and Mini- and Micro-ROVs.

RDVI uses remote digital systems such as robots or crawlers to internally inspect and assess difficult to access areas without the need for Confined Space Entry (CSE). RDVI is effective for Foreign Object Search and Retrieval (FOSAR), condition assessments 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 International Association of Classification Societies (IACS) and is a recognised member of the American Bureau of Shipping (ABS) for ‘Remote Inspection Techniques: UAV Inspection’. When combined with marine surveyors, ACIP, or API inspectors our CASA-accredited pilots are able to complete safe, efficient, and cost-effective inspections of processes, plants, or structures without the need for manned alternatives such as rope access or CSE.
