Describes the findings of an assessment study regarding valve problems in the UK Offshore Oil & Gas Industry as part of a wider initiative to reduce hydrocarbon releases. Three data-sets of information were used for the study. The valve problems were split into various groupings and generic trends by valve type were identified before the underlying causes of the problems were determined. The study shows that the underlying cause of the valve problems can be divided into two main groups - those that fall under the responsibility of the valve manufacturer and those under the responsibility of the operators or their maintenance or engineering subcontractors.
