A spill preventing device for use on a tubular portion of a well head is provided. The device has at least two sections forming an open-topped container with a bottom, the container being of a size to receive spills around the well. The container sections have a central opening in the bottom of the container of a size to fit around a tubular portion of a well head. An upstanding centrally located cylindrical flange is provided to fit around the tubular member. The flange is formed with upwardly extending walls from the container sections, which are releasably connected together to form the flange. A splash suppression assembly is positioned in the open-topped container to prevent liquid from splashing out. The splash suppression assembly has a plurality of rings mounted above the bottom of the container. The rings are concentrically positioned about the central cylindrical flange.
A device for use on a tubular portion of a well for reducing spills comprising:
Environmental well installation comprising a well casing and equipment attached to said casing, an open topped container positioned around said installation, said container having side walls and an exterior rim axially positioned above the bottom of the container, and a centrally located cylindrical flange in the center of said container, said cylindrical flange extending axially from the bottom of said container to an axial height at least as high as the rim on the side walls of said container, at least one drain in the side wall of said container, a conduit connected to the drain, a pump with the intake side connected to the conduit, a tank connected to the discharge of said pump for accumulating liquids pumped from said container, said container comprising at least two sections releasably connected together by flanges along the interface between the two sections, seals between the interfacing surfaces on the two sections, releasable fastener means joining the two sections together.
