Standardization in the field of offshore structures used in the oil & gas and lower carbon energy industries, which includes as it pertains to the substructure (for generation and substations) for:

  • Oil and gas
  • Offshore structures for use of lower carbon/renewable energy production (e.g., wind, wave)
  • Offshore CO2, H2, NH3 storage
  • Platform re-use in new locations and/or re-purposed
  • Installation and removal
  • Life extension


Aspects of offshore structures subject to IMO [International Maritime Organization] requirements" which are covered by TC 8 (Ships and Marine Technology) and directly by IMO and Classification Societies or by IEC TC114 Marine energy - Wave, tidal, and other water current converters and TC88.

Note: Application specific requirements for different energy industries will be taken from the relevant industry overarching standards. One example of this is for offshore wind turbine support structures, where the IEC standards would be expected to define wind loading, return periods and other high level requirements that offshore turbine wind support structures shall meet.
