Abstract
The use of abrasive entrainment waterjet technology to cut objects located at the bottom of a body of water. Abrasive is conducted to an abrasive waterjet cutting head under the control of an abrasive feed and metering system that monitors the differential pressure between the cutting head and reservoir of abrasive material and maintains the pressure at the abrasive reservoir greater than the pressure hydrostatic pressure at the cutting head.
