The thesis focuses on the legal basis regarding the coastal state's measures against transboundary environmental pollution following an act of terrorism or sabotage against offshore oil and gas installations. Whereas states have an obligation under the law of the sea to protect and preserve the marine environment from activities under their jurisdiction and activities from their vessels, the law of the sea is rather ambiguous regarding the rights of coastal states in cases of transboundary pollution due to acts of sabotage or terrorism towards offshore oil and gas installations.
