a mainstream line of a pipeline for transporting a working fluid therethrough;
a bypass line including an inlet and an outlet fluidly coupled to mainstream line;
a scraper receiver vessel coupled within the bypass line, the scraper receiver vessel including a receiver housing arranged to receive a scraper therein and a hatch removably coupled to the receiver vessel housing;
at least one kicker valve coupled within the bypass line downstream of the scraper receiver vessel, the at least one kicker valve operable to throttle a flow of the working fluid through the bypass line to zero;
a filter apparatus coupled within the bypass line upstream of the kicker valve, the filter apparatus operable to remove sludge and solid particles from the working fluid passing therethrough to prevent the sludge and solid particles from being carried to the at least one kicker valve; and
a pair of block valves fluidly coupled to the filter apparatus, a first block valve being coupled upstream of the filter apparatus and a second block valve being coupled downstream of the filter apparatus.
