RN01: CO-ORDINATION OF DELIVERABLES // APPENDIXDetail Description of New Work Item ProposalsBARENTS 2020 PROJECT PHASE IVNew Work Item Proposal forISO TC67 Arctic International Standards DevelopmentNWIP1TITLE OF PROPOSALNew ISO Standard: Ice Loads in Structural Design (alternatively revision of ISO 19906)SCOPE OF PROPOSALBackground informationBarents 2020 is developing a guidance document for design against ice loads on stationary floating structuresthat may serve as a common Russian-Norwegian separate supplement to ISO 19906 for the Barents Sea. TheGuidance Document may be submitted, partly or in full, to ISO for their consideration in connection with thefirst update of ISO19906.ProposalBarents 2020 has identified ten (10) topics for considerations as amendments to or changes in ISO/DIS 19906or topic for separate standard on ice loading. The ten topics which were identified by the group are listed inprioritized order below (prioritized meaning largest gaps on top of list):1. Floating structures2. Load combinations3. Ice data collection4. Ice management5. Ice basin model tests6. Improved guidance on when and how the ice load approaches in ISO19906are applicable and their ranges of validity7. Ice induced vibrations8. Loads from icebergs9. Uncertainties10. IcingPURPOSE AND JUSTIFICATIONPrepare a document for design and operations in the Arctic that will include the identified gaps and may beused as input to the first update of ISO19906 or separate standard.Information on floating structures in the ISO 19906 is limited. E.g., only generalities are offered in thenormative part A8 or A13 involving check lists and general recommendations for design, but no guidance oninduced ice actions, including ice scenarios is offered.Ideally one would like a standard/code to include information and guidance on a methodology that isaccurate. Currently this is missing for floating structures in ice infested waters.RELEVANT DOCUMENTS TO BE CONSIDERED• ISO 19906• Guidance document from Barents 2020, planned end 2011.280RUSSIAN–NORWEGIAN COOPERATION PROJECT
RN01: CO-ORDINATION OF DELIVERABLES // APPENDIXBarents 2020BARENTS 2020 PROJECT PHASE IVNew Work Item Proposal forISO TC67 Arctic International Standards DevelopmentNWIP2TITLE OF PROPOSALNew ISO Standard: Arctic Operations – Topside FacilitiesSCOPE OF PROPOSALTo make a stand-alone standard for topside oil & gas production facilities with amendments to existingstandards. See 2a, 2b, 2c and 2d as examples.Reference is also made to list of standards requiring modification for use in Arctic environment given inBarents 2020 <strong>report</strong> <strong>phase</strong>3.PURPOSE AND JUSTIFICATIONISO 19906 “Arctic Structures” is covering arctic operation specific additional requirements to existingstructural ISO TC67 standards. Similarly an “Arctic topsides” standards could be a collection of arcticoperation specific additional requirements for topsides systems and installations.RELEVANT DOCUMENTS TO BE CONSIDERED• ISO 19906• Guidance document from Barents 2020, planned end 2011.Report no 2012-0690 281
