Abstract

The grouted clamps will strengthen the offshore platform jackets which have fragile nodes and the damaged structure underwater. Theoretical analysis of buckling on the jacket was done with buckling theory under uniform axial compression and the method of finite element analysis under the condition of pipeline before and after the installation used by grouted clamp in order to ensure the reliability and safety of the offshore platforms. Experiments of grouted clamps strengthening the damaged pipe had been made and verified its reinforcement effect. This method of combining theory with experiments has sufficiently shown that the strengthening device of grouted clamp is a simple and feasible reinforcement method; it can solve the difficulties in offshore platforms nowadays by local strengthening technology on contact node of pipe and underwater steel bars.
