The oil sector is the third key industry where the technology appears to have a strong pull . As with the water sector , the low risk of using ice to clear pipes is an attractive proposition for an industry that operates with an inherently hazardous and valuable liquid product .
Following testing for one of the world ’ s largest oil companies , projects are now being studied that will inevitably stretch the technical limits of the technology . This includes projects involving delivery of ice pigging on oil platforms , the decommissioning of sub-sea oil pipelines , and cleaning pipes in some of the remotest parts of the world .
The experience with ice pigging is that many industries usually describe themselves as conservative , risk-averse , and slow to change — and probably with good reason . At the same time , the same industries often show great interest in innovation as a means of saving money , time and effort . The challenge is to recognise the paradox that this presents , remain patient with early adopters , and have the legs to stay in the game long enough until the innovation becomes the norm . u
