    • (d) in respect of the foundation, section 5.4 of Canadian Standards Association CAN/CSA-S472-92, Foundations, Offshore Structures.

  • (2) Every vessel or barge used for the construction, transportation, up-ending or positioning of an installation or a component of an installation shall

    • (a) be classified by a classification society or have documentation to prove that a similar verification process has taken place;

    • (b) if manned, be equipped with lifesaving appliances in accordance with the Life Saving Equipment Regulations, as if it were in waters to which those Regulations apply; and

    • (c) be certified by the owner as being capable of performing the assigned task or tasks safely and as being otherwise fit for the services it is expected to provide.

  • (3) All slings, wire cables, shackles and any other component used for lifting and for securing loads during the construction, transportation, up-ending or positioning of an installation or a component of an installation shall have a minimum load factor of 3.

  • (4) Where loads developed during movement of a platform from the construction site to the production site or drill site or during installation operations are in excess of those that will be encountered after installation, the platform shall be provided with load- and strain-measuring devices during the movement or installation of the platform.

PART IVOperations and Maintenance

Manual, Plans and Programs for Installations

  •  (1) Subject to subsection (2), every operator shall prepare, adhere to and maintain, in respect of every installation, an operations manual that contains the following data:

    • (b) information as to environmental conditions at the site where the installation will be installed and the effect of those conditions on the installation, including

      • (i) environmental conditions for which an installation will be evacuated and the meteorological forecast following which such evacuation will be initiated,

      • (ii) the amount of snow and ice that may be allowed to accumulate on the installation,

      • (iii) the amount of marine growth that may be allowed to accumulate on the installation, and

      • (iv) for a mobile platform, any operating limits imposed by environmental conditions and the effect of wind, sea, snow, ice and marine growth on the strength, stability and seaworthiness of the platform while in transit, in the operating condition or in the survival condition;

    • (c) for a fixed platform, the characteristics of the platform foundation, bottom penetration and the maximum permitted amount of scour or other changing seabed conditions;

    • (d) for a mobile platform that is supported by the seabed,

      • (i) information concerning the different seabed conditions acceptable for the installation, including the varying capacity of the seabed, limiting values of seabed slope, and maximum and minimum penetrations of footings, and

      • (ii) a program for inspecting for scour at regular intervals and after storms of a specified intensity;

    • (e) for a floating mobile platform, information concerning stability, including all data and instructions necessary to determine whether any intended configuration of, or change to, the loading or ballasting will satisfy the stability requirement for the platform;

    • (f) information concerning permissible deck loads, variable load limits and preloading;

    • (g) details of any colour coding system used on the installation for the safety of personnel;

    • (h) information on corrosion protection systems used and any requirements for the safety and maintenance of the systems;

    • (i) details of openings and means of closure in watertight compartments;

    • (j) drawings that show

      • (i) the general arrangement of the deck structure, accommodation areas, helideck and equipment contained on the topside facilities,

      • (iii) for a gravity-base platform and a fill-retention platform, the lower concrete or steel platform including any skirt arrangements or piling, the deck structure connection to the lower structure, the risers and the conductors,

      • (iv) for a self-elevating mobile platform, the main and supporting platforms, the equipment for the elevating and lowering of the deck structure and any arrangements for towing,

      • (v) for a column-stabilized mobile platform, the main and support structure, the method for maintaining the station and arrangement for towing,

      • (vi) for a surface mobile platform and any similar-shaped platform, the hull structure and the positioning equipment,

      • (vii) for a fill platform, the erosion protection and a cross-section of the platform including the locations of the conductors,

      • (viii) the locations of escape routes, fixed fire- extinguishing systems and life-saving appliances,

      • (ix) the fire divisions and the location of associated equipment, such as fire dampers,

      • (x) the location of the hazardous areas on the installation, and
