Summary
Investigation of a subsea gas and condensate release during high pressure cap removal at Åsgard’s S template. The cap was removed with an isolation valve open. Findings examine barrier testing and securing, unclear responsibilities, deficient operational procedures and risk assessment. How the valve changed position remains unknown.
