On inspection of a complex culvert system UK Diving Services confined space team discover extensive damage to a reinforced concrete invert due to scour followed by undermining. Our inspectors measured the voids underneath each area of concern and recommended urgent remedial works to prevent further damage threatening the integrity of the structure. All data was recorded in accordance with the Roads & Bridges Manual BD63/17 and BD 97/12 and a scope for remedial works implemented. UKDS is one of the UK's leading bridge inspection companies for investigation of underwater assets.

UKDS have provided work boats and pontoons for urgent repair and maintenance works at Prudhoe Paper Mill. The recently refurbished sludge/pulp tank required water baffles to be adjusted to allow a more even flow over the circular perimeter of the tank. UKDS provided trained commercial divers and boat skippers to assist with the project which was completed ahead of time.

UK Diving Services Ltd have provided a complete under and above water model of Thrapston Nine Arches Bridge to determine if any structural damage or underwater scour is present. Our diving team and underwater surveyors scanned the structure over a period of 5 days. Deliverable's were laser and sonar data in .pts and .xyz files allowing viewing of a point cloud.

UK Diving Services Ltd are working with Kier WSP on behalf of Northamtonshire Highways providing diving services supported by hi resolution three dimensional sonar surveys on a nine arch masonry stone bridge. The 3D mapping data in .xyz format for point cloud will show undermining and scour holes within the structure and adjacent areas. The invert, piers and abutments are scanned by placing a transducer on a tripod as well as fixing to a vessel using gps. 

UK Diving Services Ltd have recently completed 4no x underwater principle inspections for Kier WSP on behalf of Northamtonshire Highways. The surveys from our dive service identified scouring and undermining to some of the upstream elements of the structure. Repairs included placing of underwater scour packs into voids beneath the masonry structure and placing scour protective rock up to adjacent bed levels. This is a typical example of how important dive services are when protecting underwater structural assets from scour and undermining

UK Diving Services have successfully provided dive surveys to numerous bridge structures across Kent, Sussex, Surrey and Scotland. The surveys were to assess the condition of recent remedial works undertaken at each structure. Written reports were provided including detailed digital photography and video.

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. 

UK Diving Services Ltd have undertaken a full underwater sonar and diving inspection of the intake screens on behalf of Zenith for Scottish Power. The intake screens  and forebay were at 12m depth and clear of debris. NDT inspection of the steel work was carried out. 2D sonar provides helpful underwater images to back any diving inspection or survey

UK Diving Services Ltd have undertaken an internal inspection of of a decommissioned concrete sewage effluent pipe. the purpose of the survey was to understand the condition within the pipe to determine if the structure is structurally sound to support plant crossing the adjacent access road. The pipe was in a flooded state during inspection.

UK Diving Services recently completed a variety of principle bridge inspections on behalf of ATKINS engineering. The works included underwater inspection and sonar surveys of two large multiple arch bridges spanning the Ladybower reservoir. The structures were built during the second world war prior to damming and flooding of the valley and villages below. An interesting project that demanded extensive planning and skill due to the depth of the bridge piers which met bed level at 31m.

UK Diving Services have been contracted on behalf of CAPITA to provide a river wall condition survey to determine suitability prior to the construction of a new road to link to the new River Wear crossing. The new road bridge will be a two span cable stayed bridge with an A-frame pylon rising to 105m crossing the River Wear between Castletown and and Pallion. The new bridge will have two lanes of traffic in each direction, plus cycleways and footpaths along its full length. Our dive team inspected a variety of structures along the wall from concrete piers and sheet pile walls to areas of timber fenders and rock embankments.

UKDS have secured a river wall inspection in Sunderland north east England. The survey involves underwater inspection of the tidal river wall over several hundred meters. Due to likely poor visibility within the area divers will be using tactile probing methods of inspection backed by 2d sonar images.

UK Diving Services have been awarded and undertaken 30 bridge inspections on behalf of SWECO and Glasgow County Council. The bridges include most of the roadway bridges on both the tidal and non tidal river Clyde. The inspections included underwater sonar and video recorded to BCI format.

As an add-on to our conventional underwater diving inspections UK Diving Services Ltd now provide Hi-resolution 2D & 3D multi-beam sonar surveys  to survey  river beds, stone piers, concrete bag work, sheet pile walls, docks, moorings, scour holes and abutments etc. For further details please email us.

After severe flooding earlier this year UK Diving Services assisted with an urgent requirement to provide underwater surveys to several bridges on the river Dee and Don to assess their structural integrity. The surveys were completed on time successfully and written reports and video footage submitted. Other bridge inspections were also undertaken on smaller waterways including some confined space access

UK Diving Services win a confined space access contract with AECOM. Services include providing access to flooded culvets where diffrential pressure and other site specific hazards are present. The inspection will include cctv, UT readings and ndt.

UK Diving Services Ltd have taken delivery of a new aluminium  lifting barge to assist with our day to day diving and marine operations. The vessel comes complete with spud legs for extra stability for lifting heavier loads onto the large storage deck. The vessel is road transportable so can mobilise to any UK location at short notice. Lifting capabilities are up to 5 ton. Call our team for further information if you wish to hire or charter this pontoon lifting barge.

UK Diving Services Ltd recently undertook an inspection of a bridge with flooded box beams.The inspection involved surveying inside the chambers of the flooded box beams including the voids and diaphragms between them. CCTV footage was taken during the inspection.

UK Diving Services Ltd provided the diving expertise to assist Commercial Boat Services with recovering a sunken Camper & Nicholson motor cruiser on the river Trent in Nottingham. Our 5 man HSE dive team attached 6no x 5ton IBU's to the the vessel whilst she was laying on the river bed at Holme lock. Once the motor cruiser was re-floated the team from CBS towed her to a local crane site where she was lifted to shore in one piece.

UK Diving Services Ltd provided safety boat services whilst operatives took core samples and screw pulls along Albert Embankment as part of the Thames Tideway Tunnel project. As part of any works on the tidal Thames where operatives are working on the foreshore the PLA (Port Of London Authority) require a safety boat to be in position in the event the tide were rise and cut off any person from safe egress. Other considerations are swells up to 1.2 m from passing vessels. Our team were security checked by the MET Police.

UK Diving Services Ltd deployed a commercial dive team to inspect the underside of HMS Gleaner whilst she was moored at Harwich. The ships commander was experiencing vibration at increased rpm. Our diver found and removed nylon netting from the starboard propeller and prop shaft solving the technical issue.

UK Diving Services Ltd have provided dive support for a salvage vessel in the North Sea. UK Diving Services Ltd were contracted by Boskalis Westminster to assist with a possible slipped anchor

UK Diving Services Ltd were contracted in to provide rescue and safety boat services for operatives working in shallow water underneath a rail bridge in Yorkshire. In addition our company provided floating platforms and work boats to assist with the essential bridge maintenance. The scaffold was erected and dismantled one arch at a time so not to overload the weak bridge.

UK Diving Services Ltd were contracted in today to Southampton docks by Carnival UK to remove a mooring line sucked into a bow thruster of the cruise ship Queen Victoria. On arrival at port side 5 hrs prior to the ships scheduled departure our dive team were made aware of a mooring rope snagged to the underside of the forward section of the ships hull. On investigation it was found the line had been pulled into the thruster duct. Our diver removed the line within a couple of hours and the vessel sailed as scheduled
