Rescue towing with DV to a place of safety
ORIGIN of the word SALVAGE: mid 17th cent. (as a noun denoting payment for saving a ship or its cargo): from French, from medieval Latin salvagium, from Latin salvare ‘to save.’ The verb dates from the late 19th cent.
Steel plate patches, wooden patches, security bolts, lifting bolts, spinter boxes, cofferdam work, salvage purposes, sacrificial anodes bolting, etc. are allowed with the use of a submarine bolt driving gun
This is an explosively actuated gun, which instaneously and without previous preparation of the plate (Mild Steel, H.T. or D. Quality Steel), drives at high velocity, special steel alloy threaded bolts into steel plate up to 1 inch thick. The bolt is of special 100-ton tensile steel with shearing strength of 10 tons per bolt.
The lengthy and costly business of drilling, threading and bolting by norrnal methods is replaced by this most effective process. Bolts can be immediately and rigidly secured in the structure with strengths considerably in excess of the mild steel bolts usually employed.

Bolts have been driven through a solid brass plate over 5 inches thick.
Bolts are available for wide variety of applications (Threaded bolts, Punch bolt, Hollow bolts)
It is of heat-treated alloy steel, and of a tensile strength of 90 tons per square inch, and will take a 15° bend before yielding. A pressure of 12 tons is required to force the boit out of 1" plate. Bolting strengths are considerably in excess of those obtained with the usual mild steel bolts.
