Underwater RAPID ATTACHMENT for PATCHING
Water Ingress?… Fuel or Oil Leak?
Remote location? No possibility/time for Underwater Welding or dry docking?
Environmental Pollution Risk?!!
We can travel with our portable tool everywhere to assist you
We operate this underwater fixing tool for quick and reliable fastening of threaded studs and drive pins to secure patches approved by the maritime authorities
Underwater patching is a matter of minutes, up to 36 mm thick high tensile shell plating. Video: here
We can provide our customers with:
- Steel or aluminium patches with Epoxy Resin (drive pins or threaded studs driven through up to 36 mm marine steel with Epoxy Resin to perfectly seal the whole)
- Plywood patches (bolted with Epoxy)
- Security bolts and lifting bolts install
- Underwater grinding and cutting
- cofferdam work
- Safe fixing/lifting for Salvage purposes
- Sacrificial anodes bolting/riveting, etc..
Underwater Hydraulic Drill
Cox Submarine Bolt Driving Gun (obsolete)
(Replaced by SUPRAFIX: much lighter, faster and easier to use with a quick underwater reloading)
This is an explosively actuated gun, which instantaneously 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 normal methods (if no access to the opposite side) 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 bolt out of 1″ plate.
Bolting strengths are considerably in excess of those obtained with the usual mild steel bolts
