This document describes the objectives and functional requirements for the control and mitigation of fires and explosions on offshore installations used for the development of hydrocarbon resources.
This document is applicable to the following:
— fixed offshore structures;
— floating systems for production, storage, and offloading.
Mobile offshore units as defined in this document and subsea installations are excluded, although many of the principles contained in this document can be used as guidance.
This document is based on an approach where the selection of control and mitigation measures for fires and explosions primarily caused from loss of containment is determined by an evaluation of hazards on the offshore installation. The methodologies employed in this assessment and the resultant recommendations will differ depending on the complexity of the production process and facilities, type of facility (i.e. open or enclosed), manning levels, and environmental conditions associated with the
area of operation.
NOTE Statutory requirements, rules, and regulations can, in addition, be applicable for the individual offshore installation concerned.

This document covers single and double leaf, hinged and pivoted, steel based doorsets. Throughout this document the term “doorset” will be used to cover both doorsets and door assemblies. It prescribes the methodology for extending the application of test results obtained from fire resistance test(s) conducted in accordance with EN 1634-1.
Subject to the completion of the appropriate test or tests, the extended application may cover all or some of the following examples:
— integrity (E), integrity/radiation (EW) or integrity/insulation (EI1 or EI2) classification;
— door leaf
— side, transom and/or overpanels;
— louvres (ventilation / air transfer grilles);
— wall/ceiling fixed elements (frame/suspension system);
— glazing for door leaf, side, transom and flush over panels;
— items of building hardware;
— decorative and protective finishes;
— intumescent seals and non-intumescent (smoke, draught or acoustic) seals;
— alternative supporting construction(s).
This document does not cover horizontal doorsets.
The effect on the Classification ‘C’ for the doorsets following an extended application process is not addressed in this document.
