Security of offshore oil and gas facilities: exclusion zones and ships’ routeing

Abstract

The article discusses the legality at international law of establishing security exclusion zones beyond 500 metres around offshore oil and gas facilities on the continental shelf and implementing ship routeing measures, and requiring ships, particularly foreign flagged ships, to comply with such zones and routeing measures. It also discusses state practice in with regard to safety or security zones and ship routeing measures as well as problems relating to enforcement of interferences with security or safety zones around offshore facilities or non-compliance with prescribed routeing measures and other related security arrangements.
