Apparatus for dislodging an accretion of a substance from the vicinity of a vessel, includes apparatus for generating gas-borne shock waves in the vicinity of a vessel, thereby to expose a substance accrued on a surface thereof to separation forces causing at least partial separation of the substance from the surface, so as to facilitate removal of the at least partially separated substance therefrom; and support apparatus for supporting the apparatus for generating shock waves in a selected association relative to the vessel.

Method and apparatus for dislodging accrued deposits from a vessel

A self-firing and self-propelling gas impulse device which includes a housing having a longitudinal axis, a gas inlet port, and one or more gas discharge ports; an inlet chamber, arranged for gas communication with a source of compressed gas via the inlet port and operative to receive compressed gas therefrom; a pressurization chamber arranged for gas communication with the inlet chamber thereby to facilitate a build-up of pressurized gas therein, and arranged for selectable gas communication with the one or more discharge ports; and a piston unit arranged along the longitudinal axis of the housing between the inlet chamber and the pressurization chamber. The piston unit is selectably movable between a first operative position and a second operative position, whereat in the first operative position the piston unit prevents gas communication between the pressurization chamber and the one or more discharge ports, and whereat in the second operative position the piston unit is retracted so as to facilitate gas communication between the pressurization chamber and the one or more discharge ports.
