Fire Resistance
Published in Mavis Sika Okyere, Fixed Offshore Platforms, 2018
A platform can be divided into a number of fire compartments. A production platform and an accommodation platform can be ‘separated’ from each other in this way. The intention of the compartmentalisation is to limit the spread of fire as much as possible. Compartmentalisation is achieved by placing partitions which are classified as class A, class B, class C and class H. Partitions of different strengths can be placed depending on the degree of compartmentalisation. In class A, B and H, the number after the letter shows how long (in minutes) the partitions are fire resistant or fire retardant. After the stated number of minutes, the rise in temperature on the side not exposed to fire is so high that the fire will spread by means of fire transport. The fire will no longer be resisted/delayed by the partition. H-120 is used especially as a partition wall between the production platform and accommodations. This wall is resistant to the extreme heat of a liquid fire for 2 hours. The start or the spread of a fire on an offshore installation should be prevented in the earliest stage possible (Nutec 2008).
Fire Safety of Historical Buildings: Principles and Methodological Approach
Published in International Journal of Architectural Heritage, 2019
Redundancies have to be introduced, so compartmentalization is supported by active control of pressure in areas that need to be free of smoke so that air flows from the safe place towards the fire and not the opposite (ex. Pressurized stairs). Means of egress can be duplicated in case one is blocked by smoke or fire. The fire service is the ultimate redundancy to the overall strategy. Details on the components and implementation of a fire safety strategy can be found in reference (Hurley and Rosenbaum 2015).
