Apparatus for treating a surface bounding a space within which a bulk supply of flowable material can be contained

In combination:

• a) an apparatus for treating a surface bounding a space within which a bulk supply of flowable material can be contained, the apparatus comprising:
• a support having a working portion with spaced working sections;
• at least one flexible tube at each of the working sections through which a fluid from a pressurized supply can be directed,
• the at least one flexible tube on each of the working sections movable continuously in a whipping action to thereby cause a force to be applied to a surface at or adjacent to which the flexible tube is located to thereby at least one of:
• a) apply a fluid;
• and b) separate matter adhered to a surface at or adjacent to which the flexible tube is located,
• the at least one flexible tube in each of the working sections simultaneously engageable at different locations on a surface to be treated;
• and
• a moving assembly for the elongate support,
• the moving assembly operable to controllably reposition and/or reconfigure the elongate support thereby to controllably place the at least one flexible tube on each of the working sections at different selected locations with respect to a surface to be treated by the apparatus;
• and
• b) a floating vessel in which a bulk supply of flowable material can be stored and transported on a navigable body of water, the floating vessel having a cargo hold with the surface bounding the space within which a bulk supply of flowable material can be contained and within which the apparatus at least partially resides with the at least one flexible tube moving continuously in a whipping action to thereby cause a force to be applied to the surface.
