Design Method of an Expansive Stressed Grouted Clamp on a Joint of a Jacket Platform

This paper introduces the design method of an expansive stressed grouted clamp on a joint of a jacket platform. The general design requirements are summarized initially. Then the four design principles are put forward. The principles including the verifications of slip capacity, bolt prying force and crushing loads help to determine the basic dimensions of clamp structure. The structural st ength is checked by finite element method referring to the principle of structural strength. A design example that the clamp is used for repairing a K-joint of an offshore jacket platform located i n the Bohai Sea is introduced to make a clear description of the design process.
