Vertech’s Marine Department was formed through the amalgamation of our Marine Class Team and Geo Oceans to form a single, cohesive team that prides itself on its pro-active, solutions-based approach. Vertech Marine is a highly experienced, dedicated team of office and site-based professionals. We specialise in the statutory inspections for the classification of ships and offshore floating structures and subsea inspections using the latest technology, proprietary inspection tools and cutting-edge software solutions.

Vertech's Marine Department is dedicated to unmanned and manned access, inspection and preservation solutions of marine structures. We are driven to innovate, develop and collaborate with subject matter experts and clients to be industry leading and to provide the safest, most cost-efficient service available.

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.

  • Class approved repair plans
  • Comprehensive survey planning
  • Operational audits
  • Vessel stability modelling
  • 360° interactive mapping surveys
  • Fatigue management
  • Anomaly tracking
  • Work pack generation

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. Our manned services include:

  • 3D Laser mapping
  • Pre-Docking surveys
  • Baseline inspection surveys
  • Special survey management & implementation
  • Crop and renew surveys
  • RBI driven class inspection

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.

  • Subsea Mag Nautilus corrosion mapping
  • Mechanical specialised NDT
  • Accredited Mini ROV ballast tank inspection & testing
  • ABS accredited UAV inspections
  • Next gen robotic crawlers and cameras
  • Cathodic protection inspection and testing
  • Mini-ROV mooring inspection
  • HP Blasting, cleaning and maintenance



Vertech has deployed our full suite of capabilities encompassing all project requirements through the successful delivery of 8 campaigns, over 6 years without s single recordable incident.This Project includes program and project management, Engineering, class inspections & liaison, advanced NDT corrosion mapping, asset deployed ROVs, welding, fabrication, maintenance, confined space entry & rescue capabilities, heat stress management and BA entries.


Vertech were contracted to provide a turn-key package to successfully complete the Ningaloo Vision Special survey 8. The scope entailed all project management, survey planning, scope and work pack development and delivery of the full special survey and NDT to a compressed schedule. The team proudly achieved or exceeded all Key performance indicators and delivered the Special periodic survey for our customer.


Vertech were engaged to mobilise a multi-disciplined inspection and specialist maintenance team with equipment to perform critical hull integrity inspections and heavy rigging for the replacement of the cargo piping system within the hull of an FPSO. The team were able to reduce time and cost and get the facility back to full production ahead of schedule and under budget.


Vertech were awarded a Contract to provide baseline class inspection services on two offshore floating facilities while they were under construction in South Korea.Our class inspection package streamlined the hull and tank inspection and reporting process to align with the shipyards aggressive schedule and successfully deliver the hull and tank baseline inspection package for input into each facility RBI. A total of 253 tanks were inspected in a contraction shipyard environment without a single recordable incident.


Vertech were engaged to deliver cargo tank inspection services on areas of the hull that were inaccessible by conventional methods. The successful UAV inspections reduce H&S risk to personnel and saved the client 3 week of additional work while significantly reducing the amount of confined space entry and working at height.


Vertech performed un-manned ROV ballast tank inspections on an offshore FPSO. We completed all 14 ballast tanks in a 3-week campaign satisfying the class society and client, saving them several months of additional work. This innovative Asset deployed ROV service removes the need for ballasting, isolation, initial entries and human intervention driving significant cost, time and resource reductions while improving safety through removing confined space entry
