First Claim:
Show all 7 claims |
Now, therefor, I claim:
1. The method of removing sea-growth from the surface of an object comprising the steps of:
- (a) forming a network from an explosive cord, said network including a plurality of sequentially detonatable segments connected together with connecting means, said connecting means comprising nonpropagative connectors and detonation delay units;
- (b) positioning the network substantially parallel and at a predetermined spaced relationship away from the surface of the object, said spaced relationship being effective to remove sea-growth from said surface and to substantially prevent damage to said surface upon detonation of said cord; and
- (c) detonating said segments sequentially, while maintaining the network and the surface submerged in a liquid.
