ABSTRACT:
A submerged object, such as a barge, is cut into pieces by a cutting apparatus suspended from a floating vessel. The apparatus comprises a blade carrier which forms channels in which a cutting blade is mounted for vertical movement. In practice, the blade carrier includes a pair of pointed anchor studs at the lower end thereof. The blade carrier is suspended above the submerged barge and is dropped thereon so that the anchor studs are impaled in the barge to hold the carrier in positionally constrained relationship therewith. Thereafter, the cutting blade is dropped onto the barge while the carrier is positionally constrained relative to the barge by the anchor studs. By repeated performance of those steps, a series of aligned cuts can be made through the object in order to divide the object into separately raisable pieces.
