shore terminal, or Floating Storage Regasification Unit – FSRU) was presented based on holistic evaluation of the impacts of potential LNG terminal. The first step was to divide the entire observed area of the Adriatic Sea of the Republic of Croatia into smaller areas by using the Geographic Information System (GIS), and to select areas where installation of LNG terminal is technically feasible based on the pre-elimination criteria. Potential LNG terminal areas were selected taking into account all pre-elimination criteria and 14 areas were selected by using pre-elimination criteria in GIS smart charts tool that enables analyses of spatial data. The second step was based on elimination criteria analyses of 14 areas selected in the first step by pre-elimination criteria analyses. Six potential LNG terminal micro-locations were singled out based on defined elimination criteria. The third step included experts’ evaluation of 38 specific sub-criteria classified into five distinctive groups of sub-criteria: economic group (11 sub-criteria), ecological group (13 sub-criteria), safety group (4 sub-criteria), traffic connection group (6 sub-criteria) and gas needs (4 sub-criteria) for six areas singled out in previous step. The fourth step was to make multi-criterial expert analysis of the six locations selected in the previous step (for onshore terminals, offshore terminals and FSRU) for three different scenarios analysis by the PROMETHEE (Preference Ranking Organization Method of Enrichment Evaluation) method. In every scenario, one group of sub-criteria was selected as the most important according to its cumulative relationship with other groups of criteria (scenario 1 – economic group of the criteria, scenario 2 – ecological group of the criteria, scenario 3 – safety) and different importance was given to every of the sub-criteria (the sub-criteria weight). The methodology presented in this paper can also be used in decision making process for other marine and coastal activities where incorporating an ecosystem approach is an important issue taking into account safety and project costs, but the selection of pre-elimination criteria, elimination criteria and the sub-criteria should be carefully adjusted to the other situation or activities.
