ABSTRACT:
A well support system is provided including a tubular riser connecting a subsea well to a surface platform. A flexible elastomeric mounting column is providing for supporting the tubular riser from the surface platform. A first support structure supports the lower end of the flexible mounting column from the surface platform. A second support structure supports the tubular riser from an upper end of the flexible mounting column, so that a weight of the tubular riser is supported in compression by the flexible mounting column. The flexible mounting column provides a substantially constant supporting force over a range of compressed displacement corresponding to a range of expected relative movement between the riser and the platform. The flexible mounting column is preloaded in compression to within its constant force output range.
