SUBSEA INSPECTION SERVICES
Subsea Inspection Services in the UAE
Frogmen Technologies is a leading commercial ROV service provider in the UAE, delivering specialized subsea pipeline inspections, underwater hull surveys and industiral tank inspections. Using ROVs in place of diver-led inspection where appropriate, we help clients different sectors reduce risk, downtime and cost without compromising the quality or accuracy of the data collected.
WHY CHOOSE ROV INSPECTION OVER DIVERS
Reduce personnel exposure, downtime and inspection cost.
Frogmen Technologies positions ROV inspection as a safer and more cost-effective alternative to sending divers into pipelines, tanks and other confined or hazardous underwater spaces.
No draining or shutdown required
Tanks and systems can remain in service during inspection, with ROVs entering through existing access points.
No confined space entry
Removes personnel exposure to toxic atmospheres, oxygen deficiency and other confined-space hazards.
Lower cost
Typical savings of 50 to 70 percent compared with traditional tank inspection methods that require draining and confined-space entry.
Faster deployment
ROV mobilisation and reporting can be arranged quickly with minimal disruption to ongoing operations.
SUBSEA INSPECTION SERVICES
Inspection coverage for marine, structural and specialist operations.
Scopes are configured around the asset, access conditions, water environment and the evidence required by the client.
Marine asset
ROV Pipeline Inspections
External visual inspection, pipeline route survey using side scan and multibeam sonar, free-span detection and measurement, burial and scour assessment, leak detection using water-quality sensors, and emergency damage assessment following anchor drags, vessel impacts or storms.
Marine asset
ROV Tank Inspection
Internal and external surveys of water, oil, chemical, marine, wastewater and industrial tanks without draining or confined-space entry. Coverage includes floors, walls, internal structures, anodes and cathodic protection.
Marine asset
ROV Hull Inspection
Inspection of ship hulls, offshore platforms and floating structures to identify fouling, corrosion and structural issues, helping clients avoid unnecessary dry docking.
Structural asset
Dam Inspection
Assessment of spillways, foundations and intake structures on dams and hydroelectric facilities, capturing data in deep or turbulent conditions to support structural integrity and regulatory compliance.
Structural asset
Bridge & Tunnel Inspection
Underwater inspection of bridge and tunnel infrastructure, including piers and supports, to check for cracks, scour or erosion affecting structural stability.
Specialist support
Sonar Assisted Search & Recovery
Detection and retrieval support for lost equipment, debris and other submerged objects in low-visibility or deep-water conditions.
Specialist support
ROV Rental Services
Frogmen Technologies also offers ROV units for rental to clients running their own underwater inspection, survey or subsea operations.
OUR EQUIPMENT
Inspection-class systems selected around the task.
Frogmen Technologies operates observation and inspection-class ROVs selected according to the inspection scope. Depending on the unit deployed, operations can be carried out to depths of hundreds of metres.
CHASING M2 S
A compact inspection-class ROV for general visual monitoring and lighter underwater survey tasks, suited to tanks, hulls and shallow- to mid-depth infrastructure checks.
CHASING M2 PRO MAX
A higher-specification ROV within the CHASING M2 range, equipped with more advanced sensor options for detailed assessment work on pipelines, dams and structural assets.
CHASING X SERIES
Part of our observation-class fleet, used for rapid visual surveys and site reconnaissance ahead of a full inspection scope.
CHASING Gladius Mini S
A compact, 4K camera equipped underwater drone rated to 100 metres depth with a 200 metre horizontal range with extended runtime.

INSPECTION PROCESS
A controlled inspection workflow.
Our six-phase process is drawn from our inspection workflow and applied consistently across our inspection services.
Pre-Ops , Calibration & Risk Assessment
On deck systems check, equipment calibration, and review of the asset, environment and access conditions to identify hazards
General Visual Inspection
An initial observation pass to assess the overall condition and structure of the asset in situ, before any detailed work begins.
Cavitation Cleaning
Safe, high efficiency removal of marine growth and biofouling from the structure, without damaging underlying coatings.
Close Visual Inspection
High definition optical mapping and defect logging once the surface has been cleaned.
NDT & CP
Ultrasonic thickness gauging and weld integrity assessment, alongside CP probe readings to confirm the corrosion protection system is performing correctly.
Reporting
A structured report with annotated imagery, findings and measurement data, formatted for client, class or regulatory use
FREQUENTLY ASKED QUESTIONS
ROV and subsea inspection questions, answered.
Use these answers as a quick guide when scoping an underwater inspection or survey.
What are ROV inspection services?
ROV inspection services use remotely operated vehicles to carry out underwater structural surveys of pipelines, tanks, hulls and other submerged assets.
What is a subsea inspection service?
A subsea inspection service is an underwater structural survey used to assess marine infrastructure, pipelines, hulls and other submerged assets.
Do you provide underwater survey services for tanks and pipelines?
Yes. Our underwater survey work covers pipeline route surveys, tank inspections, hull assessments, dam surveys, and bridge and tunnel checks using ROVs fitted with sonar, cameras and measurement sensors.
What is your subsea inspection workflow?
We perform equipment checks and calibration first, followed by cavitation cleaning where required, close-visual inspection, and non-destructive testing.
Why use cavitation cleaning before an underwater inspection?
Cavitation cleaning removes marine growth from the inspection area, exposing the underlying surface so structural defects and measurement points can be assessed accurately.
What assets do your commercial ROV services cover?
We inspect ship hulls, subsea pipelines, dams, offshore platforms, jackets, tanks and other submerged infrastructure.
How long can an inspection ROV stay underwater?
Many inspection ROVs operate through a surface tether that provides continuous power and communications. Operational endurance is therefore governed primarily by the inspection plan, equipment limits, environmental conditions and crew requirements rather than a small onboard battery.
