Portable Abrasive Water Jet Cutting
Aquablast’s simple and highly practical field cold cutting equipment can be used for even the
biggest jobs.
These pictures show an Aquablast cold cutting gear in use where a floating tank roof in a large
oil storage tank at the MotorOIl complex near Athens had collapsed.
The roof sections had to be cut up into manageable sections to allow removal by crane from the
tank bottom. Extensive crude residues in the foot of the tank precluded any conventional hot
cutting methods.
An Aquacutter cutting nozzle transport ‘bug’ was used to guide the low reaction force abrasive
jet over the 6 mm buckled plates at an average cutting rate of 7 metres per hour. Garnet consumption
was less than one kilo per minute and the use of a 200 – ton crane allowed very large sections to
be removed at each lift.
