ISO 13702:2024

Overview

ISO 13702:2024 - Oil and gas industries - Control and mitigation of fires and explosions on offshore production installations - Requirements and guidelines - defines objectives and functional requirements for preventing, controlling and mitigating fires and explosions on offshore production installations. Its primary goals are safety of personnel, environmental protection, asset protection, and minimization of financial and consequential losses. The standard applies to fixed offshore structures and floating systems for production, storage and offloading (FPSO/FSO); mobile offshore units and subsea installations are excluded (though principles can be used as guidance).

Key topics and technical requirements

ISO 13702:2024 is organized around risk-informed, performance-based requirements and includes:

• Management system and risk framework
  • Risk assessment process, hazard identification, analysis, evaluation and treatment.
• Risk treatment and design strategy
  • Prioritization of mitigation measures and verification of performance standards.
• Installation layout
  • Functional requirements to reduce fire/explosion propagation and facilitate emergency response.
• Emergency shutdown (ESD) and blowdown
  • Hierarchy and functional requirements for safe shutdown to limit escalation.
• Control of ignition and spills
  • Measures to prevent ignition sources and limit hydrocarbon releases (including guidance for floating LNG).
• Emergency power and resilient systems
  • Requirements to maintain critical safety functions during incidents.
• Fire and gas (F&G) detection systems
  • Detection objectives, sensor functions and performance expectations.
• Active and passive fire protection
  • Firewater systems, deluge, fixed firefighting systems, and passive barriers (A-class and H-class introduced).
• Explosion mitigation
  • Blast description, mitigation measures and protection of pressurized equipment.
• Response, inspection, testing and maintenance
  • Operational response, periodic testing, inspection regimes and lifecycle considerations.
• Annexes
  • A: Typical hazardous events; B: Guidance on control and mitigation practices; C: Design examples for large integrated installations.

Practical applications and users

ISO 13702:2024 is intended for use across the lifecycle-design, construction, commissioning, operation, maintenance and decommissioning-by:

• Offshore installation owners and operators
• Design and engineering companies
• Safety, process and risk engineers
• Regulatory bodies, classification societies and auditors
• Emergency response planners and maintenance teams

Use cases include developing fire/explosion strategy, specifying F&G systems, establishing ESD logic and verifying layout and passive/active protection for FPSO, fixed platforms and floating production units.

Related standards

ISO 13702:2024 references normative documents and should be used alongside other industry standards and local regulations governing offshore safety, process design, and firefighting systems. Consult the normative references listed in ISO 13702:2024 for specific cross-references.
