Device for temporary closure of defective oil riser pipe arrangement - has housing with at one end an opening at which housing can be attached to defective arrangement

摘要

Device has a housing (8) with, at one end, an opening at which the housing can be attached to the defective arrangement. At the opposite end of the housing, there is a movable plate (14). Pref., an additional moving plate (21) is provided with one or more openings for the oiltight insertion of a rod with, at its bottom end, a probe (25) for investigating a borehole, and a means of moving the plates (14, 21). USE/ADVANTAGE - If oil is escaping from riser pipes, it is necessary to close them quickly, and if the arrangement includes a number of pipes or boreholes it is also necessary to trace the defective ones (which cannot be seen because of the escaping oil) so that they can be permanently closed or be rectified. This device deals effectively with such occurrences.
