    $10 Loads, load effects and resistance Loads that may affect installations or parts thereof, shall be quantified.

    Guideline

    To $10 Loads, load effects and resistanceTo satisfy the requirements to loads, load effects, resistance and combinations of loads on the pipeline system the following standards should be used: ISO 13623 section 6 and DNV OS-F101 section 3, 4 and 5 for rigid pipelines,

    Conditions for development of codes

    ISO- Developed by committees- Rely on knowledge and resources of the individual committee members - Tries to achieve consensus

    DNV - DNV-OS-F101 is based on Joint Industry Projects with the resources to perform work- DNV is dependent on good relations with the industry and send all offshore codes on

    external hearings. As a result, the offshore codes are updated prior to final issue. Enables DNV to respond more promptly to industry needs.

    What do you think?

    What shall be the premises for designing a structure from structural point of view?

  • Pipeline Technology Basic Course Slide 1304 March 2009

    Safety Philosophy

  • Pipeline Technology Basic Course Slide 1404 March 2009

    The design shall also consider the consequence!

    Safety philosophy

    But some buildings are design for the unlikely event of aeroplane impacts!

  • Pipeline Technology Basic Course Slide 1504 March 2009

    Safety philosophy

    Criteria for modern design

    A pipeline shall be designed considering the likelihood of loads and consequence of failure!

  • Pipeline Technology Basic Course Slide 1604 March 2009

    Safety philosophy

    Risk is a combination of- Probability of failure- Consequence of failure

    Risk/SafetyR ~ P C

  • Pipeline Technology Basic Course Slide 1704 March 2009

    Safety Philosophy

    A pipeline shall be designed considering the likelihood of loads and consequence of failure!

    The pipeline shall be designed so that the risk is acceptable!

  • Pipeline Technology Basic Course Slide 1804 March 2009

    What do you think?

    What is acceptable risk?

  • Pipeline Technology Basic Course Slide 1904 March 2009

    Consequences

    The consequences are normally divided into- Human- Environmental- Economical

    For pipelines, this can normally be expressed in terms of:- Content (Environment)- Location class (Human)

    The consequences are divided into Safety Classes,

    Hence, the safety class depend on- Content- Location

  • Pipeline Technology Basic Course Slide 2104 March 2009

    603 As far as possible, nominal target failure probability levels shall be calibrated against identical or similar pipeline designs that are known to have adequate safety on the basis of this standard. If this is not feasible, the nominal target failure probability level shall be based on the failure type and safety class as given in Table 2-5.

    Target safety levels

    Design philosophy of DNV-OS-F101

    SystematicReview (QRA)

    Safety Objective

    Safety Class Methodology

    Quality Assurance

    Shall be established, plannedand implemented

    No single failure shall lead to life threateningsituations or unacceptable damage to facilities

    or the environment. Quantitative Risk Analysis

    Safety Class depends on fluid, location and phase of project.

    Partial Safety Factor methodology means that factored design loads do not exceed factored design resistance for any of the considered failure modes. The factors are related to limit states and calibrated for the different safety classes.
