OSTI ID:6987458
A system for running riser pipes from a floating vessel to each of a plurality of conductors set in the sea floor in a circular pattern. A vertically mooring guidance riser is first connected between the center of the pattern and the floating vessel. A permanent riser pipe is guided down to one of the conductors by use of a guide frame positioned on the guidance riser. When all of the permanent riser pipes are run, the guidance riser may be removed. Special running tools and guide frames are described.
