Abstract: A site selection study was undertaken as part of the development of an LNG terminal in Moheshkhali, Bangladesh. The main aim was to establish the optimum location for the Terminal within this challenging area, which is affected by poor, low-lying ground conditions and extreme monsoon met-ocean conditions. Key assessment criteria were identified, which included waves, currents, water levels, shipping, navigation, dredging requirements, and then allocating weighting to each criteria. A site visit was undertaken to observe all potential locations in an unprejudiced manner, independent from any previous preferences, and then to discard immediately any no-go areas. A review and analysis of all relevant available data and documents was undertaken. GIS constraint mapping was used to analyse and present the results of the data and a data-gap analysis was undertaken to highlight any important gaps that required to be completed in future phases of the project. This resulted in a short list of potential sites that were then further analysed using a multi criteria matrix evaluation (MCE). A MCE was carried out by assigning the score to each criteria and to its sub parameters. These scores were weighted according to importance of a particular criteria and a sensitivity analysis was undertaken using different weighting for the criteria. To facilitate the application of the MCE a tool was created and shared with different stakeholders, which allowed them to apply their own weightings. Based on the results of the MCE, combined with our expertise a recommendation of the preferred site was made.
