A captive shotblaster machine was successfully deployed at an oil platform off the North West shelf to prepare the platform for repainting.
The Blastrac 1-10D shotblaster from Kennards Concrete Care propels shot at high velocity onto a surface. The shot rebounds back into the machine while dust and debris is removed via a vacuum system.
According to the company, the machine is commonly used to remove old coatings and overlays from concrete surfaces, but it is also effective on steel.
The machine was hired by Temco Distributors to be used on the oil platform. The platform was covered by a substrate of deteriorated epoxy coating and sound coatings.
The machine was equipped with 85% steel shot and 15% grit to remove the coating and leave a surface profile suitable for repainting.
According to Temco, it opted for the shotblaster because the open abrasive blasting alternative would be disruptive to the day-to-day operations of the rig.
Open abrasive blasting creates a large amount of noise, dust and abrasive, requiring affected areas to be isolated. The shot blaster allowed most operations to continue in tandem.
