METHOD AND APPARATUS FOR MODULE INSERTION DURING PIPELINE INSTALLATION

摘要

A system and a method for introducing a module (7) into a pipeline (6) during deepwater pipeline installation wherein a hang-off clamp (4) supports a pipeline (16) and translates from a pipeline feeding position (20) to a module connection position (21) wherein a module (7) is connected to the pipeline. By-pass lines (12) support the pipeline and module and lower them past the hang-off clamp (4). The hang-off clamp resumes support of the pipeline and returns to the pipeline feeding position (20) with the pipeline and module.
