Abstract

The riser is a component structure with complex forces in the LNG loading arm, and due to the requirements of installation and structural function, the bottom of the riser needs to open the installation and access hole, which damages the integrity of the riser and puts forward a more severe test for the stability of the riser structure. In this paper, the buckling analysis of the loading arm riser is carried out, and the theoretical formula of the critical buckling load of the riser under the condition of opening defect and reinforcement is calculated by combining the stability theory of the pressure rod and the principle of moment of inertia. The finite element model of open and reinforced riser was established, and the influence law of open hole defect size, reinforcing structural parameters, the relationship between reinforcing and open hole position on the critical buckling response of the riser was analyzed by numerical simulation, which has guiding significance for the design and manufacture of open hole riser of LNG loading arm in engineering.
