Abstract:

Methods and apparatus for attaching a pressure washing device to a storage tank that allows adjustment of the location of the pressure washing device. One embodiment includes a mounting plate adapted to be connected to a tank opening, a second plate hingably attached to the mounting plate, and a pressure washer attachment plate hingably connected to the second plate. The hinged connections may be arranged such as to allow rotation about two axes that are substantially perpendicular to each other. Linear connection apparatus may also be provided to control the relative location between the plates. A roof mounted system includes a vertical extension arm that is suspended from a roof-mounted manway. The vertical extension arm supports a primary pivot point about which a first extension arm deploys. The first extension arm carries a telescoping extension arm that has a secondary pivot point about which pivots a wash head arm having a wash head mounted on the end.

Abstract:

A closed-loop system for cleaning vessels containing drilling fluid residue. High pressure jets of water-based cleaning fluid are used to clean the interior of a vessel. The resulting slurry is sent to one or more solids/liquid separation stages to remove drill cuttings and other drilling fluid solids. The substantially solids-free cleaning fluid discharge is recycled.
