Failure Modes Analysis of Box Structure of the Containment System in FLNG

Abstract

Abstract:

The global and local finite element models of the mainstream containment system GTT NO96 of the floating liquid natural gas unit (FLNG) are established to evaluate the structural safety of tanks under the sloshing load. The failure modes of the models under quasi-static loading are systematically simulated by finite element method. The failure zones and extreme loads for different failure modes are obtained, which could provide a reference for the design of FLNG containment system. The results suggest that the main failure mode of the current design of FLNG container is the strength failure of the cover plate of the secondary insulation box at the intersection between the bulkheads of the primary and secondary boxes, and the extreme load is 0.38 MPa.
