RISER FOR AN OFFSHORE PLATFORM Abstract of the Disclosure A riser having a 90° bend at its lower end is installed at an offshore platform by mounting the riser within casing with a horizontal leg from the 90° bend extend- ing through a hole in the wall of the casing and lowering the casing through guide funnels extending inwardly from the framework of the platform. The guides have openings in their side walls facing inwardly through which the 90° bend passes as the casing and riser are lowered. When the 90° bend is a short distance above the ocean bottom, a lug on the casing enters an oblique slot in an orienting funnel. Further lower- ing of the casing causes orientation of the casing as the lug travels through the oblique slot to a position with the hori- zontal leg of the bend in the riser extending along the desired azimuth.
