The purpose of the works was to determine the underwater condition of the concrete structure and better understand the river bed profile including locating any scour holes or undercut and or undermining from scouring issues. Any scour protection measures were to be recorded using digital 2D sonar imagery in nearly zero visibility murky silty water. 

Structural Surveys Of Bridges & Culverts Within The UK Infrastructure

A UK wide infrastructure company required a detailed visual inspection of their bridge assets to ensure the structural integrity of each underwater structure. UK Diving Services Ltd provided an inspection program including an assessment of every detail of the submerged structures making sure the bridges would be safe for continued use by the general public. Many of the surrounding localised areas were considered as environmentally sensative and strict environmental controls and protocols were implemented in line with our environmental policy.

The scope of our work included developing a project plan and safety program including field inspections and detailed written reports, Additionally much of the scope included recommending maintenance and or remedial repairs, recording video and photographic images. From the conclusive evidence UKDS provided rehabilitation or replacement options with associated cost estimates and options for developing technical and executive reports summarizing the findings. Our bridge surveyors and inspection teams developed carbon friendly access routes and scheduling systems that enabled efficient completion of the work. The bridge inspections were complied inline with BD 97/12 THE ASSESSMENT OF SCOUR AND OTHER HYDRAULIC ACTIONS AT HIGHWAY STRUCTURES for bridges, culverts and water management structures.

UK Diving Services Ltd ensured state government owned infrastructure remains safe allowing the bridges to continue to be a vital link within the communities they serve.

Underwater Sonar - The Tool Of Choice 2022

Sonar is quickly becoming the tool of choice for aiding the underwater inspection of bridge structures. They have the ability to create detailed high resolution images around bridge footings, piers, cut water's and abutments including other areas such as sea walls, dams, river walls, ports and harbors. Sonar inspections provide valuable information on underwater submerged bridge structures which may include details of damaged components, water depths and structural measurements including undercut and scour measurements. They are ideal for creating detailed scour surveys in difficult water conditions. Underwater subsea assets and infrastructures worldwide need to be surveyed regularly for problems caused by conditions including undercut, scour, impact and or structural damage. Corrosion, debris and other causes can also cause major problems needing regular inspection. Diving surveyors and inspection engineers will provide visual surveys when water conditions are clear allowing easy working. When conditions worsen and visibility becomes impaired due to murky water a more tactile hands on survey is usually required. These underwater environments can present many hazards to working divers and fortunately todays technology gives the option to reduce risk with the aid of modern sonar devices. The detail and accuracy of these sonar devices can create safe working environments for divers prior to water entry by simply understanding what the area looks like prior to getting wet. These sonar systems provide high accuracy 2D and 3D sonar scans of underwater structure and provide environmental data in zero visibility water conditions. 

Our sonar surveys provide high resolution detailed images and video in any water conditions. The sonar services we offer include simple 2D data imagery and live video imagery through to more complex 3D point cloud data. Our sonar transducers can be attached to or deployed from small work vessels, attached to poles, tripods and,ROVs. Each sonar whatever the deployment method can be used for principle and general inspections, environmental and structural evaluations and real time underwater works monitoring.



UK Diving Services Utilise New Sonar Technology To Find Underwater Vehicles And Fixed Structures

Our new sonar technology uses live sonar imagery to find underwater sunken vehicles, vessels and many other lost assets. The sonar system allows constant monitoring of any underwater object from any angle and depth. This unique system provides high resolution sonar video with exceptional detail and accuracy for later viewing. The sonar is perfect for viewing fixed structures where the water quality and visibility is poor allowing for a comprehensive visual understanding of what is happening beneath the water surface. The sonar scans assets such as bridges and culverts, dock walls and pilings, piles and sheet pile walls, pontoons, aqueducts and viaducts. Deliverables are in the form of a video file and can be linked to GPS.

Sonar is now a complimentary service with all UK Diving Services underwater surveys.

Underwater Survey And Sonar 

For the third consecutive year UK Diving Services have provided underwater services on various Bridge assets throughout Scotland on behalf of Transport Scotland.  UKDS provided a full underwater scour and condition surveys of many of the bridge structures and concluded that urgent repairs were required to several of the structures. Some of the bridge structures exhibited deeper channel piers where sea bed levels had dropped and the supporting Hercules piles had become exposed.  Repairs were undertaken including concrete grouting and the placing of extensive rock armour. Rock is a good fundamental scour protection however by protecting one pier generally tends to pass the scour problem to the next adjacent unprotected pier. We have now introduced sonar backed diving surveys for monitoring a structure's scour protection.
