APPARATUS, SYSTEMS AND METHODS FOR SEALING AND SEVERING A SUBSEA PIPELINE |
摘要 |
<p>Disclosed is an apparatus (100) for sealing and severing a subsea pipe adapted to convey fluids, e.g., hydrocarbons, and systems and methods using such apparatus. The apparatus (100) includes a housing (2) adapted to attach to the pipe, a piercing tool (28) for providing an opening in the pipe at a predetermined location and a mechanism for establishing fluid communication between a source of sealant material and space within the pipe adjacent the opening in the pipe, and a cutting mechanism (42) for cutting the pipe. Methods disclosed include piercing the pipe to form an opening, injecting sealant material through the opening into the pipe to form a fluid- tight seal, and cutting the pipe through the seal to form scaled cut ends.</p> |
