Conceptual Liquefied Natural Gas (LNG) terminal design for Kuwait

摘要

This research study investigated a new conceptual design for a modular structural configuration incorporating storage for Liquefied Natural Gas (LNG) within the base of the platform structure. The structure, referred to as a modified gravity base concrete structure (MGBCS), was envisioned specifically to be constructed at a suitable site off the coast of Kuwait. Coastal offshore bathometric information, environmental data and existing data on onshore facilities were examined in the site selection portion of the study. A finite element model of the MGBCS was developed using an industry standard finite element code that allows preliminary sizes of structural models to meet appropriate design codes. A variety of parametric and design load scenarios were investigated. This research tackles some preliminary issues that are adequate for an initial evaluation of the proposed design concept. The proposed design concept needs a lot more scrutiny in order to be sufficiently developed as a concept where it can be confirmed as a truly viable concept and investment. It was confirmed that quartering sea conditions, waves approaching at a 45 degree angle, are the most critical scenarios for the terminal based on maximum values and ranges of shears and moments. In addition, there are several interesting issues in this concept that should be further looked at for this design to be further developed. The limitations of our study must be mitigated in future designs if the proposed design concept is to be carried to the implementation stage.
