DEVELOPMENT AND UNDERSEA TEST OF UNDERWATER TRENCHER (UT)

The underwater trencher (UT) was developed for excavating trenches for laying oil flow line pipes at the sea bottom down to 70 m below the surface, dredging deep sea bottom and excavating plane foundations for undersea construction. Power is fed to the UT through an undersea cable by a generating unit installed on the main support ship on the sea surface, and the UT is a self-propelled type sea bottom pump dredger which is remotely controlled. All components, such as the travelling vehicle, hydraulic mechanism and electric equipment, are of a submersible type, which are specifically developed for use in deep sea.
