Retractable sample scoop and method for pipeline sampling

A retractable sample scoop mountable to a pipeline for taking samples from the pipeline, said pipeline comprising an opening in a pipeline wall for taking said samples, said pipeline being operable for transporting fluid comprising at least one of liquid oil, oil, gas, or petroleum products, said retractable sample scoop comprising:

• a retractable mounting mechanism attachable to said pipeline wall;
• a tubular supported by said retractable mounting mechanism, said tubular comprising a scoop end, said tubular defining an internal bend at said scoop end leading to a face that defines an opening for said samples of said fluid comprising at least one of liquid oil, oil, gas, or petroleum products, said tubular being extendable into said opening of said pipeline and retractable from said pipeline;
• a resilient seal for said retractable mounting mechanism operable to seal off around said tubular with respect to said pipeline, said resilient seal and an outer surface of said tubular being configured to permit said tubular to allow movement of said tubular through said resilient seal to permit insertion, retraction and rotation of said tubular with respect to said pipeline;
• a non-resilient seal around said tubular, wherein said non-resilient seal comprises a ferrule and said resilient seal comprises an O-ring;
• and
• a plurality of supports for said retractable mounting mechanism, a movable yoke that is secured around said tubular, interconnections between said movable yoke and said plurality of supports operable to permit movement of said movable yoke with respect to said plurality of supports and said pipeline, and a fixed yoke, wherein said fixed yoke being selectively mountable with respect to said pipeline, said fixed yoke being selectively mountable to said pipeline at a position closer to said pipeline than said movable yoke, said non-resilient seal further comprising a compression nut positioned to apply pressure to said ferrule, said non-resilient seal being configured for operation in a first mode and a second mode, in said first mode said compression nut is sufficiently tight against said ferrule to prevent rotation of said tubular with respect to said non-resilient seal, and in said second mode said compression nut is sufficiently loose against said ferrule to permit rotation of said tubular within said resilient seal and said non-resilient seal with respect to said pipeline,
• wherein said tubular is configured to be rotatable within said resilient seal with respect to said pipeline to allow said face to be oriented within said pipeline when said non-resilient seal is in said second mode of operation, said tubular is secured to said movable yoke, and said movable yoke, said plurality of supports, and said fixed yoke are configured to rotate with said tubular.
