Projects Under Development

Underwater/Marinised NDT pigs, AC Potential Difference (ACPD), Air abrasive centre hole drilling (AACHD), Waste handling systems and Funprojects

While some of the following products are at prototype stage, the processes on which others are based are still being developed/tested. However, all are viable and will be brought to the market within the short term - anyone with specific interest in any aspect of these products is welcome to contact us to get an update on the stage of development, more information or projected completion date.

Underwater/Marinised NDT pigs

Unscheduled failure of a drill pipe can result in costly delays. By using our fracture mechanics and stress measurement services one can predict how long a pipe will last with a known flaw size. However, pulling a drill string for inspection can be prohibitively expensive.

The solution is our Eddy Current crack detection pig that can be used for high-speed inspection of the internal bore of the drill pipe while it is deployed.

Originally developed for the marine industry, the pig has been designed for use in harsh environments and able to measure in water depth up to 200 meters.

As the system is computer based, calibration and setting of suitable alarm levels can be achieved for a wide variety of drill configurations. Distance measurement along the string will also allow for pinpointing the exact flaw location, allowing replacement strategies to be developed before lifting of the string.

AC Potential Difference (ACPD)

Once a flaw in a component has been found, fracture mechanics principals can be used in conjunction with measured/theoretical stress levels to determine how long that component would last. However, accurate information regarding crack size and orientation is critical in determining residual life of the component.

The solution: ACPD. By measuring minute changes in electrical potential across the flaw, accurate determination of the extent and angle of the fractures can be determined. Repeatable accuracy to within 40 micron (μm) of crack length has been measured in steels, aluminium and most conducting materials.

A wide range of devices are available, ranging from a compact hand held device to a computer based system that can map the entire flaw profile. A database for the more common material and geometrical configurations is provided with the system to assist with calibration. Calibration of other geometries and material types can also be done in our laboratory.

Air abrasive centre hole drilling (AACHD)

A common method of measuring the residual stress in a component is the centre hole drilling technique, whereby a specialized strain gauge is attached to the component being measured. The strain is measured while drilling a small hole at the centre of the gauge and used to calculate the residual stress.

Drilling of the hole, however, can introduce significant residual stresses - thus influencing the accuracy of the results. Air abrasive centre hole drilling introduces minimal amounts of residual stress during the drilling process and can be used on a wide variety of materials, from diamond to plastics.

Our drill is compact; easy to operate and has been developed to give square sided holes with repeatable drilling times allowing accurate depth determination. Accurate location is assured by an indexing micro camera, which can be interfaced with either a monitor for manual operation or with an integrated computer system that can measure stress while monitoring hole depth to give an accurate and detailed residual stress profile.

Waste handling systems

Compaction at source - the way of the future. Origen is working on a method to commercialise a cost effective, franchise-able, employment creating and efficient system.

Advantages:

  • Single compaction
  • More compact solid waste for disposal on the landfill site.
  • Removes the need for transfer stations.
  • More efficient collection of household waste.

Fun/oddball projects

Environmental concern and allowing diversity ensures that Origen remains a dynamic lateral thinking organisation and has spawned a number of projects somewhat diverse from our engineering orientated world.

Although these projects are classified as fun/pet projects they are being pursued actively - but as time allows. Interested parties are invited to contact Origen.

These projects include:

Cat feeder

Tired of having to make it home to feed your cat? Our cat feeder feeds your cat food and water at regular intervals. The unique design does not require electricity or batteries, making it reliable and convenient.

Trolley wheel

The sure way of preventing the loss of supermarket trolleys. The specialized device measures the distance travelled after leaving the store and stops the trolley at that point. A customized key system allows easy retrieval of the trolley by authorized personnel.

Bags for sand, stone, and rubble

Convenient durable flexible containers used to deliver building materials to site

Advantages:

  • Site cleanliness
  • Use of non-specialized trucks
  • Can deliver sand stone and bricks in a single load

The containers can be used to remove building waste from site - use of specialised trucks optimised.

Toilets (non water)

In a dry climate such as South Africa using potable water for water borne sewage disposal is criminal. However, the hygiene, odour reduction and general luxury of water borne sewage disposal is hard to beat. Members of Origen are working on methods of retaining this comfort but without the waste of water.
