Global Micro ROV Specialist

We are a specialist ROV inspection company providing services to the offshore oil & gas and renewables industry.
Whether inspecting a riser, caisson, conductor or the jacket structure itself, our bespoke, cost-effective, safe and efficient solutions are deployed by our highly skilled team of pilots and inspection coordinators providing exceptional service.

With more than 40 years of experience, we pride ourselves on understanding our client's requirements and providing exceptional service. We have a fleet of quality assets capable of accessing restricted underwater locations safely and efficiently, giving you access to your assets where and when you need them.

Our ROV Systems

Small and lightweight, our specialist micro and inspection ROVs can be deployed at short notice from any location to ensure effective turnaround for your priority jobs.

With the capability to access restricted underwater locations safely and efficiently, our ROVs enable you to understand exactly what's happening under the surface.

Our remote access capabilities and detailed insight reports give you visual access to your assets whenever you need them, helping you to improve asset safety and integrity while significantly reducing risk and cost.

At HPR ROV, we provide an intelligent inspection service you can trust.

Tools and Accessories

Gas Sampling

HPR ROV has developed a bespoke gas sampling unit which is attached to one of our micro ROVs. The unit collects sub-surface gas into sealed bags which are resistant to a wide range of chemicals, including most acids and acid mixtures weak bases, halogens, halogenated solvents, hydrocarbons, alcohols, salts, and oxidants. The gas sampling system is recovered to the surface and the valves on the bags are closed before the sample bag is sealed in a separate bag and delivered to the client in a Peli case for dispatch to a laboratory shore for analysis.

Cathodic Protection Surveys

The UCP1A contact probe is a lightweight and versatile instrument that has been specifically designed for use with ROVs to carry out underwater cathodic protection potential measurements. When the stainless steel probe tip of the UCP1A makes contact with the surface under test, the resulting voltage can be read on a suitable high-impedance or digital voltmeter. The UCP1A is used extensively across a wide range of applications including production and drilling platforms, ship hulls, jetties and other marine works.

Cleaning and Caviblasting

The CaviBlaster is an innovative subsea cleaning tool which is easily deployed from an ROV. The system consists of an electrically driven topside pump unit, 100 metres of hose on an air-operated reeler and if required, a 40-metre lightweight hose for primary attachment to the lance. We can offer a selection of lance options, 50/50%, 60/40% and 100%. We also have lances with multiple nozzles to suit your specific requirements.

Laser Scanning

C-Gauge System

The field-proven C-Gauge underwater measurement system offers sub-millimetric underwater measurements. The highly compact and rugged package comprises C-Laser, laser detector, and deployment detector frame designed to fit onto even our smallest of ROV Systems. Subsea measurement applications include pipeline crack, gap and ovality inspection, with precise point-to-point distance, diameter, redial and angular measurements.

C-Scan System

C-Scan is an optical 3D scanning system that can generate accurate dimensional measurements from internal and external scans. Target applications include caissons, pipes, piles, flanges anodes, and other subsea structures. The laser triangulation system takes measurements 15 times per second, generating 700 discrete data points per scan, and may be rotated through 360˚ to build up a complete 3D data point representation. A range of software tools allow data manipulation, visualisation, measurement and export to CAD packages.

FMD Inspection

The Cygnus FMD probe has an innovative and compact design which self-aligns, ensuring correct contact with the member, even when approached from an angle and can be easily deployed by ROV.

Designed to assess flooding within a parallel pipe, FMD Systems utilise ultrasound to analyse the area. If there is flooding, ultrasound will travel easily through the liquid, creating multiple reflections off the inside wall of the pipe. On the other hand, ultrasound cannot travel through the air, so if there is no flooding, no returning echo will be detected.

Leak Detection

With an almost 100% detection rate, OceanSENSE is a market-leading subsea leak detection system. A single OceanSENSE unit can detect both leaks from subsea infrastructure, and cement dye from cementing processes. When deployed in a commissioning role, OceanSENSE can be used to prove the structural integrity of spool tie-ins and subsea structures beyond the capability of the human eye to see trace dye in water.

TMS Systems

Until recently, subsea valves and structures with over-trawling frames and cocoons have not been inspected due to the tight access and egress which is too small for a large ROV to enter, and too small and dangerous to allow a diver to attempt to enter.

The HPR ROV “Buddy ROV” system combines the VideoRay Pro 4 with a garage tether deployment system (TMS) and connects them to a work-class ROV.

The unique feature of this TMS system is that there are no slip-rings and no oil compensation, removing the major fault potentials from those of conventional TMS systems. The present design can accommodate some 75 metres of tether which is more than adequate for most operations.

Further benefits include the removal of potential environmental contaminants including compensator oil and a reduction of failure points and maintenance time. The need for operator training is reduced, and safety is improved due to the removal of the need to bleed air from a slip-ring system.

Ultrasound Inspections

Designed specifically for suitcase ROV systems, the Cygnus probe can be easily attached to the VideoRay, Outland and Falcon systems. A simple gimbal arrangement allows the probe tip to stay in contact with the steel even in adverse conditions.

Key features of this ultrasound inspection solution include not needing to remove coatings; greatly reduced inspection time and cost; and being able to overlay the reading on the ROV monitor to display the exact position of the reading.

This system is accepted by major classification societies and delivers fast, accurate and repeatable inspections.
