Bespoke Camera Technology

Our camera specialists have been engineering and developing specialised bespoke camera systems for the past 3 years and have revolutionised pipeline inspection technology and cctv.

Special Pipeline Camera (SPC-15)

The SPC-15 camera was developed to record long distance potable water mains while they remain operating. The camera is launched into the pipeline and retrieved up to 14km downstream of the entry point. The footage is not live but instead is captured in 15 minute increments on an SD card which can be downloaded as soon as its retrieved.

This camera system can reach places far beyond the capabilities of any other cameras available on the global market. The SPC-15 camera is designed to be used in difficult to access places with the capability to withstand extreme conditions. This camera can operate in any type of pipe from water, sewer and industrial wastewater through to oil and gas. It can also operate in fully submerged rock shafts and bore holes on land and at sea.

It is also equipped with a tracking sonde capable of being used in steel pipes.

The camera system is capable of POI 3D scanning and for sections of the pipes that need closer inspection, these can be converted to 3D geometry when the camera is travelling at a slower rate. The scanned data obtained from the camera system needs to be analysed and processed by our team of engineers.

With the use of sophisticated 3D scanning software, data can be converted into 3D models or unwrapped on to a flat 2D image of the pipe or shaft. In addition to this, the camera can measure anomalies in the pipeline to 0.01mm which enables extremely accurate data for pipe internal diameters, angles of a pipe bend or the extent of a misaligned joint. It can provide the location and measurements of cracks and fissures in rock or be used to measure the volume of encountered obstacles.

Fibre Optic Cam

Since the development of the Rail Cam and the Tunnel Cam (see detailed below), there was need to provide footage of small diameter pipelines over long distances. Initially, there was nothing on the global market that could provide footage over long distances for small diameter pipe, so the concept of H&B’s Fibre Optic Cam was born.

The Fibre Optic Cam was initially developed for the Mt Albert sludge line repair project in Wellington. Two DN150 sludge pipes both 1.8km long concrete lined ductile iron pipes. Due to a seismic event towards the end of 2019, it was discovered that both pipes had broken and were pumping sludge into an interceptor tunnel. Neither of the sludge pipelines could be used forcing Wellington Water to run a fleet of vacuum trucks 24 hours a day, 7 days a week to transport the sludge at a cost to ratepayers of over $600,000.00 per week. The pipes were not able to be accessed by contractors, and Wellington Water had no way of inspecting and assessing the 1.8km long pipes. More project information can be found here.

The Fibre Optic Camera H&B developed can give a full live stream up to 3km of pipeline and it can also 3D scan and measure items of interest to 0.01mm accuracy. The high level of quality and accuracy that this camera system has enables thorough pipeline assessments to occur giving clients access to condition assessments of assets that has previously not been achievable until now.


Rail Cam

H&B first had the need to develop a specialised bespoke camering system for the Westport Tunnel project. A live feed was required to navigate the drill rig through the existing 1.2km sandstone tunnel and avoid striking timber shoring. The first 400 meters was achieved by installing a suspended rail cam which gave the operator a live feed during the installation which can be seen from the images.

Floor Mounted Tunnel Cam

For the remaining 800 meters of the installation, H&B developed and used another camera system that was tripod mounted and was able to obtain live footage from 700 meters away from the target area, which in this case, was the drill rig navigating through timber shoring. This was astonishing since the live footage was extremely clear, even in relatively low light conditions at such large distances, and could be relayed to the operator all whilst personnel were positioned outside of the tunnel during the entire installation. This aspect had immense health and safety benefit to the installation. The live footage obtained by the camera was captured on the monitor as shown.

Mini Swabbing Camera

This miniature camera was developed to attach behind pipe swabs / pigs. It is attached to the towing rope and footage is downloaded at completion of the pass to assess the effectiveness of the cleaning pass. This assists in determining whether the pipeline is ready for a dedicated high-definition camera pass or further swabbing.

Miniature Live Feed Inspection Camera and VR Headset

This camera head and lighting housing measures only 9.5mm diameter with a 100m long 4.86mm cable.

This camera was initially developed for camera inspecting 12mm diameter frozen pipelines under cold stores which had experienced slab heave after the heating system failed.


Troglotech T815 Crawler System (Tractor Camera)

Troglotech’s Crawler System is Lithium-Ion battery-operated and uses the latest technology for long mission times. The system is lightweight and highly portable which makes it very effective to use for both commercial and residential applications. As usual with Troglotech products, the system is highly robust with the crawler being machined from solid brass and stainless steel. With a range of quick-release wheel sets (the wheel bolts are locked into position for security) you can survey the full range of pipe sizes starting from 4” (100mm). The crawler is steerable and has a reversing camera and lights so that a survey can be performed in either direction. The batteries on the crawler have a long mission time (up to a full days inspection work) are quick-release and can be charged on-site or via a mains supply

  • Tractor 5

  • Tractor 3

  • Tractor 2

  • tractor 1

  • Tractor 4

Safety first

Troglotech’s systems are all battery operated so there are no dangerous voltages or generators required. The latest battery technology is used which provides a full days work from two crawler batteries and a single charge of the control unit battery.

 

Why battery power?

On most Troglotech Crawler Systems, up to 90% of the power is lost in the main cable. The cable could be increased in size with more copper to reduce this loss, but the crawler would need to be bigger and heavier to handle the increased load. In addition, the cable voltage at this size is often at lethal levels. The Troglotech’s Crawler System carries its own power source which means the main cable does not conduct any power. This aspect allows the unit to be much lighter in weight. The composition of the cable is mainly Kevlar and the three small conductors which only carry signals at safe voltages below 5V

Bespoke Specialised Pipeline Cameras

Given the extreme lengths and size of pipelines and tunnels that Hadlee & Brunton (H&B) work on with their trenchless technology, downhole vision is an essential tool, not only for the initial inspection works, but also during construction since this removes the need for manned entry and provides precise information for decision making.

Having struggled to find high-definition camera systems that could inspect distances in excess of 1km long and at pipe diameter ranges at both ends of the spectrum, H&B partnered with movie industry expert Piotr Wysocki (Fox) and have been developing highly specialised bespoke pipeline cameras for the last three years. The various cameras that have been developed to date have the ability to investigate, scan, measure to 0.01mm, 3D model and provide footage of pipelines that have internal diameters that range from 12mm through to 4000mm at distances of over 3km live stream and 14 km remote capture. On top of all of this, these cameras deliver movie standard image quality which far exceeds standard pipeline footage of the past.

Please refer to the images below showing the pipe scanning abilities of our bespoke cameras.


Digital Rope Counter (DRC)

Our advanced DRC has been designed to assist with work carried out in the field by counting the lineal meterage and speed of rope or cable that is being installed into the pipeline.

The biggest advantage of digital versus mechanical/analogue methods is the precision and clarity of the measurements displayed to the user.

The digital screen allows to check the measurements at any time, showing not only the length of the cable or rope but also the speed of entry in meters/min and km/h. Both those measurements allow the DRC to provide estimated time that’s needed to pull the required amount of cable/ or rope over the required distance.

The built-in high quality optical encoder ensures the precision of the taken measurements making it incredibly accurate even at long distances.

The DRC is capable of measuring ropes and cables with a maximum speed of 100km/h and length up to 99km and can measure between 1mm and 20mm diameter using a simple and quick height adjustment system.

The user-friendly simple design of the counter includes a rechargeable battery which will last for the entire day of operating which makes it portable to site and functional at sites with no power sources. It can also be operated while connected to the charger when power is available at the site.

To add to the specialised cameras that have been developed, H&B also operate a Swiss inspection drone which allows for immediate and fast inspection of most confined and inaccessible spaces above 400mm in size.


Inspection Elios Drone

Inspired by the ability of insects to keep their stability after an in-flight collision, the flight concept of Elios is the result of hundreds of millions of years of natural evolution. Using a unique and pragmatic approach, Elios solves the biggest challenges of flying drones indoor in complex and confined spaces or in contact with humans: the risk of collisions and injuries. Privileging tolerance to collisions over the attempt to sense and avoid obstacles, Elios provides the level of reliability that is expected by professionals operating in environments where failure to operate is not an option.
H&B use this inspection drone to inspect tunnels and pipelines with internal diameters upwards of 400mm. After the pipeline or tunnel has been flown, the data is extracted in the Inspector Software which enables points of interest discovered during the flight to be analysed further. There are also capabilities within the drone and software to provide thermal imaging of the inspected area.
