    Based in Vanuatu, our Dive Vessel (Class 1) is catered for Salvage and Towing, operational at any time, ready to get under way and perform in crisis demand situations, such as the salvage of vessels or aircraft due to accident or storm.
    For Yachties, we can give assistance to Yacht, such as: by fixing hull (all materials) suffering from damage (underwater patching), engineering (propulsion & hydraulic sytems), towing, etc.

      • Refloating: sunken or grounded vessel, barge, aircraft, car, pipeline, explosive.
      • Emergency Salvage: small or large outside patching*, such as water inlet connection blown from ship's side, or large splinter damage, patching on tank, Ship repair.
        *
        We use explosively actuated gun which instantaneously drives solid or hollow screwed bolts and punches holes in steel plate, above or below water, which enable salvage divers and officers to carry out in a few hours that work which hitherto occupied days and weeks.
      • Clearance Salvage: consists in a coordinate removal or salvage of numerous vessels in a waterway or harbor (collision, cyclone, tsunami)
      • Rescue Towing to a place of safety.
      • Cargo and Equipment Salvage: Cargo may pose an environmental hazard or may include expensive materials, the main focus is on the rapid removal of goods.
      • Wreck Removal: Consists in removal of hazardous or unsightly wrecks by the cheapest and most practical method possible (hull cutting or vessel refloating and scuttling in deeper waters).
      • Afloat Salvage: Mostly unobtrusive, it involves primarily damage control work (hull welding, stabilization) and structural bracing.

    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.

    Underwater RAPID ATTACHMENT

    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.
