Abstract
An autonomous junk collecting sleeve for a riser is provided. The sleeve is constructed and arranged to be independently lowered and seated above a subsea tree section and, subsequently, raised and removed independent of the work string. The autonomous junk collecting sleeve includes a first cylindrical structure, a second cylindrical structure concentric to the first cylindrical structure and which are joined together in spatial relation at a bottom end to form an interior J-channel basket. The J-channel basket is operable to collect debris traveling up through the bottom end and over of the second cylindrical structure for deposit therein.
