|
The original inventor of the DCVG technique, back in the 1980‘s, was John Mulvany, an ex Telecom Engineer, who worked with Dr. John Leeds now the Managing Director of DCVG Ltd. They worked extensively in developing and proving the technology through hundreds of kilometres of survey and more than 1000 excavations. DCVG Ltd has further developed the technology and techniques to supply equipment and training to Engineers and steel pipeline coating Survey Companies to the oil and gas industry, in more than 55 countries world wide. Some companies have purchased more than 20 sets of DCVG & CIPS equipment. |

|
DC Voltage Gradient Technology and Supply Ltd. is the worlds leading company in DC Voltage Gradient Technology with very active research into the technology and the design and manufacturing of DCVG and CIPS survey equipment, for the global pipeline industry. |

|
DCVG Ltd. is also market leader in running Training Courses in DCVG and CIPS technology, thereby allowing companies to arrange their own pipeline surveys with appropriately certified Engineers. In this respect, many companies who may be in competition to the DCVG / PIM / APRT Group are actually conducting field surveys using our DCVG and CIPS equipment. |
|
More than 25 years real experience in designing, manufacturing, using, analysing data collected & excavating many thousands of DCVG coating fault indications gives us, as suppliers of equipment, unparalleled expertise in DC Voltage Gradient Technology and its accurate interpretation; knowledge that is passed on to engineers & operators through the detailed training courses. |
