Marine Class Inspection

Vertech’s Marine and Class Inspection Department prides itself on its industry-leading services and 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 renewal 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 only complete the inspection efficiently but also 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 regarding these statutory inspections. By innovating the inspection methodologies and technologies and through our world-class, in-house team, we have delivered safe and effective services to every FPSO and FSO in Australia, New Zealand, 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 strive to 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 accreditations 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 and 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 of merchant shipping vessels, barges, tugs, and defence vessels.

Unmanned Marine Services

Vertech Group has led the charge and invested heavily in reducing and eventually eliminating manned inspections through advanced robotics, such as Unmanned Aerial Vehicles (UAVs), Remote Digital Video Inspection (RDVI), robotic crawlers, and mini-ROVs.

Geo Oceans, a Vertech Group company, has been an innovator 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 globally.

The team has 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 the 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 recently gained class accreditation with the 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, AICIP, or API inspectors, our pilots can complete safe and cost-effective inspections of marine structures without the need for manned alternatives such as rope access or confined space entry.
