ABSTRACT:
A guide member having the advantage of the "J-tube" and "bending shoe" risers, for installing a riser pipeline between a submerged pipeline and an above water facility of an offshore apparatus, is disclosed. The guide member has a J-shape and has three sections: a long, tubular, vertically extending upper section, a short, tubular, substantially horizontal lead-in section, and a curved channel section extending between the upper and lead-in sections. The curved channel section is open on a side away from the lead-in section. The resulting guide member requires a substantially smaller pulling force than would be required with a comparable J-tube riser and avoids the manipulative complications of conventional "bending shoe" risers.
