Abstract

See full text

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