The invention and development of Nivalis Ice Pigging
Although Ice Pigging is used in many industries and the equipment has been tried and tested over many years, we still want to see what else we can achieve.
In 2019 we were asked to Ice Pig fuel systems to remove bio contamination. “Can this be done?” asked the customer. “We're not sure” was our response. Fast forward to now, and we are seen as the best available technique for cleaning our customer’s ships fuel systems.
Read case studies about different Ice Pigging applications.I have been working with the Nivalis team members since 2006 on the development and deployment of the Ice Pigging technology in vastly different industries and applications. Their in-depth knowledge underpinning the technology based on their PhD research work and their awareness of what the technology achieves based on real-world experience, makes them unique.
