IMO - International Maritime Organization

IMO

Several rules and regulations govern the dimensioning of a HI-FOG® system for marine or offshore installation. These stipulations are issued and maintained by the International Maritime Organization (IMO), which is a special agency of the United Nations charged with the responsibility of the safety and security of shipping and the prevention of marine pollution by ships. Member states work within the IMO to draw up internationally agreed standards which can be applied to every ship.

In practice, the IMO rules and regulations are formulated by many different maritime safety parties, including classification societies, ship owners, ship builders, safety system manufacturers, flag states, port states, insurance underwriters, shipping financiers, oil companies and chatterers, among others. Marioff has been very active in the IMO Fire Protection Sub-Committee since 1991 in formulating water mist related rules and regulations. In fact, most of the IMO fire test protocols for water mist systems are based on Marioff testing and initiative. 

In short, the IMO sets the rules and the criteria regarding how to fulfill them, whereas the classification societies interpret the rules and apply them to shipbuilding and maintenance requirements. However, owners, as well as flag states and insurance companies, may have certain special requirements.

The most important convention concerning ship safety is SOLAS (Save Our Lives at Sea), and the requisite requirements for firefighting can be found in chapter II-2.
