There are more than 1350 offshore installations in Southeast Asia. However, the international legal framework applicable to these installations is unclear and often poorly understood. The regional legal framework, which could provide the clarity lacking at global level, does not. This is due in part to the absence of a regional consensus and of regional agreements on the marine environment.

CIL has undertaken an important amount of research on the law, rules and regulations applicable to offshore installations on the basis that such law, rules and regulations will frame national and regional policy on such installations. The research, which includes a study of the overall geographic, political and economic context of the offshore industry, is divided into three distinct lines of enquiries. The first line of enquiry examines the legal framework applicable to different types of pollution from offshore activities, with a particular emphasis on the implications for Southeast Asia. The second line of enquiry concerns the abandonment and removal of disused offshore installations, which is called ‘offshore decommissioning’ by the industry. The third line of inquiry explores the possibility of converting decommissioned oil installations into artificial reefs.

This research guide includes the main legal instruments relevant to the area of research, as well as CIL academic publications, working papers and presentations on this topic. CIL intends to continue its work on offshore installations, marine environmental law and the law of the sea and to make relevant materials available on its website with the hope that law of the sea scholars, marine policy analysts, marine ecologists, government officials and offshore industry experts will find them useful.
