Presents recommendations for designing, fabricating, and operating TFL (through flowline) equipment. Procedures are guidelines presented are for hydraulic servicing of downhole equipment, subsea tree and tubing hanger, and pipelines and equipment within the pipelines. This document primarily addresses TFL systems for offshore, subsea applications but it may also be used in other applications such as highly-deviated wells or horizontally-drilled wells. Subsea separation, boosting, metering and downhole pumps are outside the scope of this document.
This edition of 17C is the identical national adoption of ISO 13628-3:2000, Petroleum and natural gas ndustries-Design and operation of subsea production systems-Part 3: Through flow line (TFL) systems.
