Firewater deluge (FWD) systems associated with hydrocarbon production and processing are safety critical elements that must operate reliably on demand in an emergency. The consequences of failure of FWD systems in an emergency may be extremely serious.

This guidance helps to identify, understand and manage the degradation mechanisms that cause failure in FWD systems and mitigate the risk to health and safety and human life. In accordance with relevant industry fire safety standards and regulations, this guidance covers the main aspects of the corrosion management of FWD systems:

• regulatory compliance;
• verification;
• corrosion risk assessment;
• materials of construction, and
• cleaning and chemical treatment programmes.

These guidelines are primarily intended as an aid to personnel working with upstream oil and gas production and processing facilities, particularly those located offshore and at coastal onshore terminals; however, persons working in other potentially hazardous industries may find benefit in applying this guidance. It can be applied to new, existing, and ageing installations.
