ROV Inspection and Pipeline Inspection

Long Distance Pipeline Inspection

Our fibre optic crawler systems carry out pipeline inspection up to 2km from a single access point, with the capability to reach up to 4km depending on site conditions. Fibre optic control keeps live imaging sharp across the whole run and removes the need for confined space entry.

We inspect submerged pipes and tunnels from 200mm diameter upwards, in static, surcharged or fast-flowing water. A typical day covers up to 1km, so long runs are surveyed with minimal disruption.

All our pipeline inspection services include live CCTV recording, with optional 3D LiDAR scanning. See the 1.3km crawler survey case study for an example.

ROV Inspection Services

We operate remotely operated vehicles (ROVs) to reach places that are unsafe or inaccessible for confined space entry or divers. From sewer pipelines to tunnel networks, ROV inspection gives you detailed, recorded evidence of an asset’s condition without putting people inside it.

Every ROV survey can include high-resolution CCTV, sonar mapping and 3D LiDAR scanning. The data supports accurate reporting, condition assessment and planning for repairs.

Our pipe inspection services cover:

  • Pipeline and tunnel CCTV surveys

  • Sonar mapping of submerged pipes and structures

  • 3D LiDAR scanning

  • Large culvert and storm drain surveys

  • Non-destructive testing (NDT)

See how it works in our sonar and CCTV ROV survey case study.

ROV and Pipeline Inspection FAQs

What is an ROV inspection?

An ROV inspection uses a remotely operated vehicle, controlled from the surface, to film and survey assets such as pipelines, tunnels and culverts. Nobody has to enter the asset.

How far can you survey from one access point?

Up to 2km as standard, and up to 4km depending on site conditions.

What size pipes can you inspect?

From 200mm diameter upwards.

Can you inspect pipes that are still in service?

Yes. We survey in static, surcharged and fast-flowing water.

What will I receive?

Live CCTV recording as standard, with sonar mapping and 3D LiDAR scanning available to support your reporting and repair planning.

Confined Space Entry and Rescue

When manned entry can’t be avoided, safety comes first. Our teams are fully trained and equipped to carry out high-risk confined space work safely, efficiently and in full compliance with industry regulations.

We are regularly trusted with confined space operations on high-profile sites across the water, power and infrastructure sectors. All operatives are City & Guilds certified and work in line with the Confined Space Regulations 1997 (HSE), and every entry is planned, controlled and backed by a trained rescue team.

Our confined space work on the Blackfriars flume earned an award for efficiency from Tideway. If diving is the better option for your site, see our commercial diving services.

Testimonial 

“I was highly satisfied with MMP Marine and Inspection Ltd’s performance during the recent confined space inspection works we undertook together. The communication was excellent, with Robert and his team providing clear and timely information both on-site and beforehand. The equipment was in good condition and readily available, ensuring a seamless operation. MMP Marine and Inspection Ltd were well-coordinated, demonstrating their ability to control the site effectively while adhering to all safety protocols. Access to the confined space was well-managed, and the training of the rescue team was evident in their capable handling of the environment. MMP Marine and Inspection Ltd’s commitment to safety and their proactive approach to service improvement were particularly commendable.”
