The elongate member 14 includes a tapered supporting surface 18, which may be provided on a tapered stress joint or flex joint 16. The receptacle 20 includes a mounting bracket 22 secured to the structure 10, and a basket housing 30 which has a tapered interior surface 34 for mating engagement with the exterior surface 18. According to the method, the mounting bracket is fixed to the structure, and the receptacle basket positioned about the elongate member and the assembly then positioned for being supported on the bracket. The supporting surface on the basket may be arranged for positioning the elongate member at a selected azimuth and declination relative to the offshore structure.
