<p><P>PROBLEM TO BE SOLVED: To provide a suspending device for a riser, the device almost completely releasing bending moments in all directions generating between a marine structure and a riser which is used for transporting or the like of fluid resources or the like from the sea bed or the like, and also releasing shear load generated between the marine structure and the riser, absorbing an instantaneous relative displacement in a compression direction along the riser axis, and having a suspending member disposed outside the riser, and to provide a connecting device of a mooring pipe. <P>SOLUTION: The suspending device of a riser includes: a riser 1 for transporting a fluid to a fixed pipe 3 of a marine structure; a flexible pipe joint 8 disposed between the fixed pipe 3 and the riser 1 and connecting both; a plurality of rotary suspending elements 12 and 15 and a plurality of flexible suspending elements 13 and 16 disposed around the flexible pipe joint 8, for suspending the riser 1 from a bottom plate arm 11 of an ocean floating body to give flexibility in the relative displacement of the riser 1 with respect to a bottom plate 7 of the ocean floating body; and an intermediate ring 10 achieving relative angular displacement or relative horizontal movement of the riser 1 with respect to the bottom plate 7 of the ocean floating body. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
