Understanding ISO 35106-19: Technical Requirements for Arctic Operations Metocean, Ice, and Seabed Data

A comprehensive guide to the international standard for collecting and managing environmental data in Arctic petroleum and natural gas operations

Scope and Application of ISO 35106-19

ISO 35106-19, formally published as ISO 35106-1:2019 and adopted by the Canadian Standards Association as CSA ISO 35106-19, establishes the requirements and guidance for the collection, management, and quality assurance of metocean, ice, and seabed data used in design, construction, and operations of petroleum and natural gas facilities in Arctic and cold-weather regions. This standard is part of the ISO 35106 series, which systematically addresses all aspects of Arctic operations—from data acquisition to the design of structures and facilities. The scope of ISO 35106-19 specifically covers the environmental data programs that are essential for understanding the physical environment, including meteorological, oceanographic (metocean), sea ice, and seabed conditions. These data sets support risk assessment, engineering design, environmental impact assessments, and operational planning. The standard applies to all phases of a project lifecycle, from feasibility studies to decommissioning, and is relevant to operators, regulators, survey contractors, and engineering firms working in polar, subarctic, and seasonally ice-covered marine environments.

Key Technical Requirements and Data Specifications

ISO 35106-19 defines technical requirements for data collection programs, sensor specifications, measurement methods, data processing, and storage. It emphasizes a risk-based approach to data acquisition, where the level of detail and duration of monitoring is proportional to the complexity and potential risks of the operation. Key areas include:

  • Meteorological Data: Minimum requirements for wind speed and direction, air temperature, relative humidity, precipitation, and visibility. Standards for sensor placement, sampling intervals, and maintenance are specified.
  • Oceanographic Data: Requirements for current speed and direction, water temperature, salinity, water level/tidal data, and wave characteristics (including extreme wave analysis).
  • Ice Data: Dynamic ice conditions such as ice drift, concentration, thickness, floe size, ridges, and ice features (e.g., stamukhi, icebergs). The standard outlines monitoring frequency and remote sensing validation.
  • Seabed Data: Bathymetry, soil stratigraphy, geotechnical properties (shear strength, bearing capacity), permafrost extent, and seabed slope stability. Guidelines for geophysical and geotechnical surveys are provided.
  • Data Quality and Management: Requirements for calibration, metadata, uncertainty estimation, and data archival. The standard also specifies the use of standardized formats and data sharing protocols where applicable.
Tip: ISO 35106-19 should be used together with other parts of the ISO 35106 series—such as ISO 35106-2 (Physical environmental data) and ISO 35106-3 (Ice management)—to ensure comprehensive coverage of Arctic data requirements.

Implementation Guidelines for Arctic Data Collection

Effective implementation of ISO 35106-19 requires a structured approach that addresses logistical and environmental challenges unique to the Arctic. The standard recommends the following practices:

  • Program Planning: Develop a Data Acquisition Plan (DAP) that defines objectives, parameters, uncertainties, and a schedule aligned with seasonal windows (e.g., open water, winter roads) and project phases.
  • Equipment Selection: Use instruments rated for extreme cold, icing conditions, and ice impact. Redundant power and communication systems are recommended.
  • Data Validation: Implement real-time and post-processing quality control checks. Cross-reference data sets (e.g., satellite observations with in-situ measurements) to identify systematic errors.
  • Data Integration: Use a common geospatial database to store and manage all environmental data. Apply consistent coordinate systems (e.g., WGS84) and ensure traceability to national reference systems.
  • Reporting: Prepare annual data reports that summarize findings, flag anomalies, and update design criteria. Reports should adhere to the template suggested in annexes of ISO 35106-19.
Warning: Harsh Arctic conditions can severely affect sensor performance. Unexpected sea ice interaction, icing on anemometers, or blowout of moorings may cause data gaps. Contingency plans must be part of the DAP to maintain continuous data records.

Compliance, Certification, and Auditing Considerations

ISO 35106-19 is a normative standard often cited in regulatory frameworks for Arctic offshore activities, particularly in Canada, Norway, and Russia. Compliance involves demonstrating that the data program meets the requirements of the standard. Key notes for stakeholders:

  • Third-Party Verification: An independent qualified entity should review the DAP, instrument type approvals, and calibration records. This is typically required before issuing a licence to operate.
  • Certification: The standard can be used as the basis for certification of data providers (e.g., survey firms) under an accreditation scheme such as ISO/IEC 17025 for testing and calibration.
  • Auditing: Internal audits should examine data completeness, measurement traceability, compliance with QA/QC metrics, and archive integrity. Non-conformities must be resolved with corrective actions.
  • Continuous Improvement: The standard encourages the use of feedback loops—lessons learned from operational incidents and new research are incorporated into updates of the DAP.
Success: Adherence to ISO 35106-19 reduces the probability of under-designed Arctic structures, lowers operational risk, and facilitates regulatory acceptance. It also improves the reliability of environmental assessments and supports sustainable resource development.
Critical: Non-compliance with ISO 35106-19 can lead to catastrophic design failures, environmental harm, and legal liabilities. In cold regions, missing or inaccurate ice data has been a contributing factor in serious incidents (e.g., Kulluk grounding, 2012).
Q: What is the difference between ISO 35106-19 and the other parts of the ISO 35106 series?
A: ISO 35106-19 (the data requirements standard) focuses specifically on the collection and management of metocean, ice, and seabed data. Other parts cover broader topics such as physical environmental data (part 2), ice management (part 3), and facility design (part 4). They are meant to be used as a suite for comprehensive Arctic operations management.
Q: Who needs to use ISO 35106-19?
A: This standard is essential for oil and gas operators, engineering contractors, environmental consultants, and survey companies involved in Arctic and subarctic projects. Regulatory bodies also reference it when establishing permit conditions for exploration, drilling, and production activities.
Q: Does this standard apply to shipping or mining operations in cold regions?
A: Although originally developed for the petroleum and natural gas sector, the data principles in ISO 35106-19 can be adapted for other offshore and coastal operations in ice-affected waters, such as maritime transport, wind farm development, and seabed mining. However, sector-specific standards may also apply.
Q: How does ISO 35106-19 address the challenge of limited historical data in the Arctic?
A: The standard encourages use of regional climatology, hindcast models, and satellite-derived data to supplement short-term on-site measurements. It also provides guidance on Bayesian and extreme-value analysis methods to manage uncertainty when observed records are less than the recommended durations.
