RN01: CO-ORDINATION OF DELIVERABLES // APPENDIXBARENTS 2020 PROJECT PHASE IVNew Work Item Proposal forISO TC67 Arctic International Standards DevelopmentNWIP2aTITLE OF PROPOSALUpdating/Amendment toISO 13702 “Control and mitigation of fires and explosions on offshore production installations”SCOPE OF PROPOSALAmend existing with Arctic specific requirements within areas of:• Containment (prevent releases of hydrocarbons, chemicals and/or toxic substances)• Ignitions source control• Gas detection• Active fire protection• Passive fire protection• Effect of ice/snow on passive fire protection• Ventilation (natural and mechanical)• Design and proper operation of HVAC systems in cold environments.• Explosion mitigation and protection• Effect of active weather panels on explosion overpressures.• Explosion risk management• Guidance on methodology for explosion risk modelling.PURPOSE AND JUSTIFICATION• The main reference for guidance and requirements for technical safety barriers is “ISO 13702– Control and mitigation of fires and explosions on offshore production installations”. Theobjectives and main principles of the standard are generic and can be used for the Arctic.• The standard should include an informative reference to ISO 19906 forgeneral design principles of offshore arctic structures.• The functional requirements of ISO 13207 can be used as they are. The informative parts ofISO13207 should be updated to reflect specificities related to design of offshore structures incold climate. The need for update of the different sections in ISO 13207 giving requirementsand guidance on each specific safety barriers is described in the B2020 phase 3 report.Topics include:• Containment (prevent releases of hydrocarbons, chemicals and/or toxic substances)• Ignitions source control• Gas detection• Active fire protection• Passive fire protection• Effect of ice/snow on passive fire protection• Ventilation (natural and mechanical)• Design and proper operation of HVAC systems in cold environments.• Explosion mitigation and protection• Effect of active weather panels on explosion overpressures.• Explosion risk management• Guidance on methodology for explosion risk modelling.RELEVANT DOCUMENTS TO BE CONSIDERED• ISO 19906• Barents 2020 phase 3 report282RUSSIAN–NORWEGIAN COOPERATION PROJECT
