INTRODUCTION

This thesis aimed to investigate the prevention and compensation of transboundary damage resulting from the construction and operation of oil and gas pipelines. Five research questions were identified in Chapter 1:

In this Chapter, the key findings of this study are presented along the research questions reflecting the purpose of this thesis. In order to answer the research questions, this thesis employed different research methodologies. A comprehensive literature review and a systematic elaboration of the international legal regime governing cross-border pipelines have been carried out to answer research questions. Furthermore, economic analysis of law has been used to evaluate the design of environmental and safety regulations applicable to such pipelines.

CONCLUDING REMARKS

RISKS ASSOCIATED WITH PIPELINES

The first research question of the thesis concerns the risk associated with the construction and operation of oil and gas pipelines, in particular the possibility of occurrence of trans-boundary damage. In the thesis, an overview of data regarding the number of gas and oil pipeline accidents was provided. By considering the published data, it can be argued that, pipelines have not led to many accidents. Of course, the current number is still considerable. Furthermore, although the number of accidents is high enough to call pipelines hazardous activities, they have not frequently led to transboundary damage. However, as accident reports indicate, pipelines have the potential to cause personal injuries, environmental damage and economic losses in the trans-boundary context. A brief overview of the contribution of various causes of failure has been conducted in the thesis. It was revealed that external impacts and technical defects are the main failure causes in both oil and gas pipelines, although they slightly differ.
