Canada Oil and Gas Installations Regulations — 62
62 (1) Every subsea production system shall be designed to withstand major damage under the loads listed in Part B, Section 4, of Det norske Veritas Guideline No. 1-85, Safety and Reliability of Subsea Production Systems . (2) Where the concept safety analysis required by section 44 indicates a risk of damage to the subsea production system components from ice, dropped objects, trawl board nets or anchors, the design of the system shall include measures to minimize such damage. (3) The rigid risers in the subsea production system of a fixed offshore platform and the steel flowlines and flowline connectors in every subsea production system shall comply with National Standard of Canada CAN/CSA-Z187-M87, Offshore Pipelines . (4) Every subsea production system and its components shall be subjected to equipment integration tests in accordance with section 7.2 of American Petroleum Institute RP 17A, Recommended Practice for Design and Operation of Subsea Production Systems . (5) Every subsea production system shall be installed in accordance with section 7.3 of American Petroleum Institute RP 17A, Recommended Practice for Design and Operation of Subsea Production Systems . (6) Every subsea wellhead system and subsea tree located in a caisson, silo, or glory hole shall be designed and installed in such a manner that (a) the effect of silting is minimized; and (b) where practicable, inspection and maintenance during its production or injection life is possible. (7) Every subsea production riser shall be designed and operated in accordance with section 6 of American Petroleum Institute RP 17A, Recommended Practice for Design and Operation of Subsea Production Systems . (8) Every subsea production riser shall be designed (a) to withstand the maximum pressure to which the riser may be subjected during its service life; (b) so that every component that is used to transport oil or gas from the seafloor to the production installation can withstand without failure the wellhead shut-in pressure, except where the component is equipped with an isolation valve at the seafloor and a pressure relief system at the platform to relieve the internal pressure of the component; and (c) to withstand any ice loads to which it may be subject as determined pursuant to section 45, except where failure of the riser will not lead to uncontrolled pollution. (9) Flexible flowlines and risers in a subsea production system shall be designed in accordance with Det norske Veritas Technical Note TNA 503, Flexible Pipes and Hoses for Submarine Pipeline Systems . (10) The end fittings of flexible flowlines or risers in a subsea production system shall have pressure integrity and load-bearing capacities greater than that of the pipe. (11) The fatigue life of risers in a subsea production system shall be at least three times the service life of the production riser. (12) Adequate provision shall be made in the design of the risers in a subsea production system and in the configuration of their individual components, including production, injection, control and instrumentation lines and their attachment assemblies, for the safe and efficient maintenance and inspection of the risers and their components during their service life. (13) The analysis required by section 41 of the risers in a subsea production system in relation to fatigue and stress of the riser components and risk to the personnel and equipment as a result of failure or malfunction of individual components of the risers shall be performed using the methodology specified in section 6.5 of American Petroleum Institute RP 17A, Recommended Practice for Design and Operation of Subsea Production Systems . (14) Every riser in a subsea production system shall be equipped so that it can be disconnected (a) before heave or excursion limits specified in the operations manual are exceeded; or (b) when ice conditions pose a threat of major damage to the production platform. (15) Every riser on a subsea production system
