Underwater ROV Inspection Services

Utilizing underwater Remote Operated Vehicles, commonly known as ROVs, is a safe and cost-effective way to efficiently inspect and assess underwater infrastructure and assets that are not easily accessible by other means.  Areas that are prone to limited visibility and potentially tight spaces are ideal for ROVs as these specialized underwater vehicles use high resolution optical and sonar sensors and dynamic positioning equipment to enhance visual acuity and operational maneuverability.

Whether you are planning a new infrastructure project, expanding an existing asset or assessing an existing installation to ensure optimal operability and integrity, Intertek’s underwater ROV technology, part of our Advanced Unmanned Robotics Services (AURS) offering, is delivered worldwide by our team of expert technical personnel and provides the data and visibility you need to make critical decisions that help minimize safety risks and ensure success. 

Intertek’s AURS underwater integrity inspection ROV services focus on ports, industry and offshore wind and offshore oil & gas assets. At any of these locations, our ROV technology is able to provide ultrahigh-resolution underwater visual, video, photo and NDT inspection results validating integrity, corrosion condition and seabed clearance certification.  Intertek’s AURS team uses rapid deployable, state-of-the-art ROV’s with advanced navigation, DP capabilities, 3D stereo imaging systems, mechanical cleaning systems and subsea NDT systems.

PORTS

• for assets such as quays, sheet piles, mooring posts, wharfs, jetties, dock pillars, bridges and other constructions

INDUSTRY

• for assets such as cooling water systems, pipelines and valves, storage- and water tanks

OFFSHORE WIND

• for offshore wind assets such as wind farm foundations, underwater cables and offshore substations.
• optimized to deliver unparallelled structure integrity condition inspection, CPS inspections, corrosion mapping, coating condition, scour protection condition

OFFSHORE OIL & GAS

• for assets such as production platforms, drilling rigs, pipelines and FPSO’s.
• optimized to deliver unparallelled structure integrity condition inspection, riser-, conductor-, flowline- and wellhead inspections, corrosion mapping, coating condition, scour protection condition

In addition to the advanced inspection and survey ROV services, we also offer these ROV services:

• Subsea Digital Imaging – 0.1mm/m accurate 3D modelling and photogrammetry
• Marine Growth Management - 3D modelling and measuring, identification and growth predictions and treatment plan
• Microbiological Influenced Corrosion Management (MIC) – sampling and laboratory analysis and advice on treatment
• Advanced Subsea NDT – Ultrasonic Testing (UT), Cathodic Protection measurement (CP/ICCP), Flooded Member Detection (FMD – ultrasonic)
