Project Tugboat: Explosive Excavation of a Harbor in Coral
Abstract
A portion of a planned small boat harbor was explosively excavated in a weak coral material using twelve 10-ton charges of an aluminized ammonium nitrate slurry explosive. The charges were emplaced approximately 36 feet deep in the coral reef which was overlain with about an average 6-foot depth of water. Charges were spaced 100 feet and 120 feet apart. A series of five calibration tests preceded the main harbor detonations. The detonations resulted in a channel varying in width from about 150 feet to 260 feet at a minimum project water depth of 12 feet. The berthing basin is almost a square area 400 feet on a side at the 12-foot water depth contour.
