Marine Class Inspection

Vertech’s Marine and class inspection department prides itself on its industry-leading services and its proactive, solutions-based approach. The marine team is a highly experienced, dedicated team of office and site-based professionals who live and breathe hull structures and class rules. Our team specialises in statutory inspections for the classification of ships such as tank surveys, crop and renew surveys, UWILDS, special surveys and other applicable class inspections for offshore floating structures and subsea infrastructure.

We use the latest technology, proprietary inspection tools and cutting-edge software solutions to not just complete the inspection in the most efficient manner but also to provide high-quality, repeatable and compliant reports, models and data sets that make it easy for the accrediting surveyor and client to achieve all of their specific project requirements.


Vertech Group is known to provide best-in-class service when it comes to these statutory inspections. By innovating the inspection methodologies, and technologies and through our world-class, in-house class team we have delivered safe and effective class services to every FPSO and FSO in Australia, New Zealand as well as services in West Africa, Brazil, the Gulf of Mexico, and Asia.

Through our Group companies including Vertech, Geo Oceans, AUAV, Blue Ocean Marine Services and Sonomatic, as well as partners such as 3X engineering, we have access to a global network of the best inspection, integrity, and composite technologies available to support our clients.


Marine Class Integrity Services

With innovation being one of Vertech’s core values, we are striving be at the forefront of an ever-evolving market. We provide a broad array of engineering and repair capabilities to support marine class inspections, as well as providing ongoing integrity management of Mobile Offshore Drilling Units (MODUs), Floating Production Storage & Offloading facilities (FPSOs), Floating Storage and Offloading vessels (FSOs), Floating Liquefied Natural Gas (FLNG), and Merchant Marine Assets.

Vertech holds accreditation’s with all major societies for close up surveys, thickness measurements, in-water surveys, and remote inspection including: AS/NZS 45001:2018, NATA NDT Inspection, American Bureau of Shipping (ABS), Bureau Veritas (BV), Det Norske Veritas (DNV), and Korean Register (KR). Over our years of service, we have developed strong working relationships and gained extensive industry knowledge, allowing us to minimise the impact of the inspection on production and resources.

Manned Marine Services

As a testament to our client focus, high quality service and specialist marine packages, we have been chosen to complete complex campaign and compliance inspections on every FPSO in Australia and New Zealand as well as many others in the wider Asia Pacific and West Africa regions.

In addition to oil and gas assets we have completed integrity and class inspections on merchant shipping vessels, barges, tugs, and defense vessels.

Unmanned Marine Services

Vertech group has led the charge and invested heavily in reducing and eventually removing manned inspections through advanced robotics such as Unmanned Aerial Vehicles (UAV’s), Remote Digital Video Inspection (RDVI), robotic crawlers, and mini-ROV’s.

Geo Oceans, a Vertech Group company, have been innovators in the subsea inspection and marine sectors from its inception. This multi-award-winning business has driven a paradigm shift in the oil and gas market, seeing them now operate on a global scale.

The team have developed the Advanced Robotics System (ADV-ROV), designed to perform asset deployed ROV inspections of vessel hulls, jackets, moorings, and riser systems from the splash zone to subsea. The robotic system is powerful, robust, and lightweight, perfectly designed for work in challenging conditions such as the splash zone.

ADV-ROV capabilities include conventional UT and CP NDT, crack detection methods & corrosion mapping, advanced NDT, FMD, and marine growth & scale removal.

Vertech has recently gained class accreditation with International Association of Classification Societies (IACS) and is recognised member of the American Bureau of Shipping (ABS) for “Remote Inspection Techniques: UAV Inspection”.

When combined with marine surveyors, AICIP or API inspectors, our pilots are able to complete safe and cost-effective inspections of marine structures without the need for manned alternatives such as rope access, or confined space entry.
