Overview
ISO 13354:2014 - Petroleum and natural gas industries - Drilling and production equipment - Shallow gas diverter equipment specifies requirements for selecting and applying diverter systems used when drilling shallow-gas‑bearing formations. The standard covers both onshore and offshore operations and addresses auxiliary equipment for floating rigs. It focuses on the safe selection, design considerations and operation of primary diverter components including annular sealing devices, vent outlets, diverter valves and diverter piping. ISO 13354:2014 also highlights safety concerns for marine floating drilling supports and prescribes important pre‑spud actions and preparedness measures, while giving general guidance on responding to shallow‑gas flows.
Key topics and technical requirements
- Scope and definitions: Terms and definitions for components such as annular sealing devices, bag preventers, and control functions.
- Diverter system equipment: Selection and functional requirements for:
- Annular sealing devices (torus‑shaped housings and packing elements)
- Vent outlets and their placement
- Diverter valves (types and actuation)
- Diverter piping and associated fittings
- Design considerations: Separate guidance for land/bottom‑supported rigs and floating rigs, including control systems, kill‑line provisions and auxiliary equipment for riser drilling.
- Floating rig specifics: Use of marine risers, additional diverter functions, and differences among moored drill ships, DP drill ships and semi‑submersibles.
- Preparation and operations: Requirements for pre‑spud checks, pre‑spud meetings/drills, crew preparedness and basic well‑control measures.
- Maintenance and certification: Guidance on diverter system maintenance, certification/recertification and manufacturer documentation.
(Note: ISO 13354:2014 provides selection and procedural requirements and general guidelines; it does not replace site‑specific engineering analysis.)
Applications and practical value
- Helps operators and drilling contractors specify and select diverter equipment appropriate for shallow‑gas risk environments.
- Guides rig designers and equipment suppliers in integrating diverter systems into new or modified rigs (land and offshore).
- Supports drilling supervisors, HSE teams and well‑control specialists in preparing pre‑spud plans, drills and emergency response procedures for shallow‑gas scenarios.
- Improves safety by standardizing considerations for dynamic loads, erosion risks, vent routing and control systems on floating supports.
Who should use this standard
- Oil & gas operators and drilling contractors
- Rig designers and equipment manufacturers
- Well‑control engineers and HSE professionals
- Regulatory bodies and certification authorities evaluating diverter system compliance
