In this paper a new method to reinforce X joints is presented depended on the connection between pontoon and leg of semi-submersible. As a part of total research, this paper extends numerical study to sleeve reinforced X-joints subjected to compression load through systematic variation of the main geometric parameters. The load transferring mechanisms and failure modes of such joints, with different sleeve size, are investigated and compared with corresponding un-reinforced joints. Within the range of geometric parameters investigated, the sleeve is observed to provide strength enhancement up to 200% for the corresponding un-reinforced joint. Design recommendations are provided for this joint type.
