ABSTRACT:
A system for removing deposits from an underwater structure comprises a series of interconnected dog members which can be formed into a ring and adjusted angularly relative to one another to conform to the underwater structure. The series of dog members is supported by floats, which allow a preassembled line of dog members to be moved into position and wrapped around an underwater structure. The free ends of the line of dog members are connected together by a pin having a latching spring which can be operated easily underwater. Multiple rings can be used, one above another. An annular net, secured to concentric rings and suspended underneath one or more deposit removal rings, catches dropped deposits. The inner one of the concentric rings can also be used as a deposit removal ring. The dogs can also be disposed in a vertical ring for removal of deposits from a horizontal underwater structure, and a suspended basket is used to catch dropped deposits. For removal of deposits from the hull of a ship, an arrangement consisting of two longitudinal deposit removal structures extending alongside the ship, and multiple parallel transverse deposit removal structures extending underneath the hull, is used.
