What is ISO/TS 35105 - Material requirements for arctic operations about ?
ISO/TS 35105 provides recommendations for material selection, manufacturing and fabrication requirements, testing and qualification of steel structures and components for offshore and onshore petroleum and natural gas facilities operating in Arctic and cold environments.
ISO/TS 35105 is intended to be used as a supplement to existing standards for steel structures where the particular operating conditions in Arctic regions are not sufficiently addressed.
ISO/TS 35105 gives particular requirements to ensure safe operation with respect to the risk of brittle fracture at low temperatures.
Note- The requirements in ISO/TS 35105 are applicable to any operating temperatures, but particular requirements related to de-rating (loss of strength) at high temperatures are not addressed. Limitations to the applicable minimum design temperature caused by the capability of the materials’ low temperature performance can exist, but are not a limitation for the scope of ISO/TS 35105.
As a practical guideline for the use of this document, low temperature is defined as lowest anticipated service temperature (LAST) below –10 °C.
Who is ISO/TS 35105 - Material requirements for arctic operations for ?
ISO/TS 35105 on material requirements for arctic operations is useful for:
- Petroleum and natural gas industry
- Offshore and onshore companies in Arctic and cold environments
Why should you use ISO/TS 35105 - Material requirements for arctic operations ?
Operations in an Arctic environment are characterized by low ambient temperatures, the presence of sea ice and ice bergs and icing of structures and components. In many cases they are also associated with remote locations relative to infrastructure and logistics. Maintenance operations are therefore expensive and accidents leading to emissions can have severe environmental consequences.
Structural failure is in most cases failure of materials and caused by well-known degradation mechanisms such as fatigue and corrosion. Under Arctic conditions, failure due to possible brittle materials behaviour needs to be given special consideration.
ISO/TS 35105 was developed to bridge the gap between the functional requirements to offshore structures in Arctic environments given in design standards and the material requirements given in material and fabrication specifications where Arctic operating conditions have not been considered in sufficient detail.
ISO/TS 35105 also gives guidance which is helpful:
- To mitigate the operational and integrity aspects related to snow and ice accretion on topside structures
- To take into account the particular Arctic operating conditions in corrosion assessments and requirements for corrosion protection systems
- For particular operational requirements to ensure safe operation in Arctic regions
