The new ISO 19906 standard and related arctic activities at DNV

ISO 19906, the new offshore standard on Arctic Offshore Structures, has been issued as International standard for the Arctic and cold regions. The standard represents consensus in the industry and the best practice on protection of personnel, the environment and assets when operating under Arctic conditions. The standard’s normative sections set requirements for performance while the informative sections include specific recommendations for meeting the normative requirements. Furthermore, Det Norske Veritas (DNV) is the Norwegian project manager for the Barents2020 project, with the objective of implementing a common set of rules and standards for health, safety and the environment in the Barents Sea. The focus is on Russian-Norwegian cooperation and the initiative is supported by the national governments. The project builds on the results of the ISO 19906 process and suggests how the results of ISO 19906 in general can be implemented in the Barents Sea region. DNV has an ongoing Joint Industry research Project “IceStruct” with the objective of supplementing the ISO standard with a design guideline document related to calculation of ice loads and other structural design parameters for structures located in ice. Of particular focus is the ability to predict ice actions and action effects on floating installations. This paper will present the current results of the ISO process and the relationship with the related mentioned DNV projects, with an emphasis on ice-related design issues. An example is included on how to determine, with the use of FORM, a contour in a space of two governing parameters where the contour is connected to a joint probability of those two parameters. In this example iceberg impact energy is chosen due to its simplicity. The results are compared against a probabilistic model.
