Regulations are current to 2014-10-27 and last amended on 2009-12-31. Previous Versions

 Environmental Criteria and Loads

  •  (1) For the purposes of undertaking the analyses referred to in section 40, the determination of environmental criteria and loads on an installation shall be made in accordance with sections 5 and 6.5 to 6.13 of Canadian Standards Association CAN/CSA-S471-92, General Requirements, Design Criteria, the Environment, and Loads.

  • (2) For the purposes of undertaking the analyses referred to in section 40, permanent loads, operational loads and accidental loads shall be determined in accordance with sections 6.2, 6.3 and 6.4, respectively, of Canadian Standards Association CAN/CSA-S471-92, General Requirements, Design Criteria, the Environment, and Loads.

  • (3) For the purposes of undertaking the analyses referred to in section 40, for installations, load combinations shall be determined in accordance with section 6.14 of Canadian Standards Association CAN/CSA-S471-92, General Requirements, Design Criteria, the Environment, and Loads.

 Site Investigations

  •  (1) Site investigations shall be carried out, for the purpose of undertaking the analyses referred to in section 40, in accordance with section 4 of Canadian Standards Association CAN/CSA-S472-92, Foundations, Offshore Structures.

  • (2) Where permafrost is present at a production site, the geotechnical investigation for the purposes of undertaking the analyses referred to in section 40 shall include sampling of the permafrost.

  • (3) The analysis of all fill sources for an installation shall meet the requirements of section 7.3.2 of Canadian Standards Association CAN/CSA-S472-92, Foundations, Offshore Structures, and shall include sampled boreholes and laboratory testing of the recovered samples.

Geotechnical Parameters

 For the purposes of undertaking the analyses referred to in section 40, the geotechnical parameters used for stability, deformational and thermal analyses shall be selected in accordance with section 5.2.5 of Canadian Standards Association CAN/CSA-S472-92, Foundations, Offshore Structures.

Soil Deformation

 For the purposes of undertaking the analyses referred to in section 40, the analysis for determining the deformation of foundations shall be made in accordance with sections 5.2.4, 6.1.3, 7.1.3, 8.1.3 and 9.2.4 of Canadian Standards Association CAN/CSA-S472-92, Foundations, Offshore Structures.

Erosion Offshore

  •  (1) For the purposes of undertaking the analyses referred to in section 40, the analysis of the erosion offshore shall be made in accordance with sections 6.2.3, 7.2.2 and 9.3.5 of Canadian Standards Association CAN/CSA-S472-92, Foundations, Offshore Structures.

  • (2) Where there is a potential for erosion around a platform to a degree that would affect the stability of the platform, the platform shall be

    • (a) provided with means of erosion protection that eliminate or prevent that degree of erosion; or

    • (b) designed assuming all materials that are not resistant to erosion, determined from physical or numerical modelling, are removed.

  • (3) The operator of a platform or drilling unit that is placed so close to an existing platform as to cause erosion that affects the stability of the existing platform shall take measures to prevent that erosion.
