Abstract
A system for blast-cleaning a barge bottom providing for safety and avoidance of damage to the barge and to persons, where a barge is blast-cleaned with a blasting tractor having a transverse track beam along which positioning units move blaster heads. In one embodiment, the blasting tractor is controlled by a person in a cab of the blasting tractor, where the operator can see the blaster heads. In another embodiment, the blasting tractor is robotically controlled from a robotic controller which has access to a three-dimensional plan of the barge, communicating with the robotic blasting tractor via RF antennae, and receiving real-time data from sensors located on each blaster head. Optionally, the system for blast-cleaning a barge can provide blaster-head cameras for real-time remote monitoring of operations and for recording of the operations allowing review of any issue, such as damage, that might arise.

AMENDED CLAIMS
received by the International Bureau on 30 September 2019 (30.09.2019)
I claim:
1. A system for blast-cleaning a barge bottom, supported on blocks in a work building, by a human operator, the system for blast-cleaning a barge bottom comprising:
(i) a blasting tractor adapted to move longitudinally along the underside of the barge and adapted to house an operator within eyesight of the blast- cleaning operation;
(ii) a transverse track beam mounted upon a front of said blasting tractor and extending outwardly from the tractor in a direction transverse to longitudinal movement of the tractor, said transverse track beam having longitudinal dimensions substantially similar to transverse dimensions of the barge bottom;
(iii) at least one positioning unit adapted to move along said transverse track beam; and
(iv) at least one blaster head mounted upon said positioning unit adapted to move with said positioning unit and move relative to said positioning unit; where, in use, said positioning unit with said blaster head is moved along said transverse track beam, and said blaster head is moved in relation to said positioning unit, under the control of the operator, such that all unblocked surfaces of the barge bottom are reached with blast media.
2. The system for blast-cleaning a barge bottom of claim 1, further comprising a blaster-head camera.
3. The system for blast-cleaning a barge bottom of claim 1, further comprising a blaster-head sensor.
4. The system for blast-cleaning a barge bottom of claim 1, further comprising a blaster-head sensor adapted to sense objects through a cloud of blast media.
5. The system for blast-cleaning a barge bottom of claim 1, further comprising a blaster-head sensor adapted to make sensor readings during pauses between pulses of blasting.
6. The system for blast-cleaning a barge bottom of claim 1, further comprising a blaster-head sensor adapted to determine absolute location from fixed reference beacons placed inside the work building.
15
