| Abstract | The TurkStream pipeline system is currently being constructed across the Black Sea for supply of natural gas from the Russian coast near Anapa to landfall on the Turkish coastline. The pipeline design is extremely challenging from a technical perspective with water depths along most of the route exceeding 2200m, difficult seabed conditions with steep slopes and geohazard risks, a potentially aggressive and corrosive subsea environment, and high gas deliveries requiring a large pipeline diameter. The combination of diameter, wall thickness, and quality requirements for the TurkStream linepipe is at the limit of leading mills around the world, and outside their normal production envelope. In order to demonstrate that the manufactured linepipe will meet target reliability levels, a material development program was completed, which included a major testing program involving testing prototype TurkStream pipes manufactured by both the UOE and JCOE methods of linepipe fabrication. The results from this test program formed the basis for a probabilistic verification of the pipeline wall thickness. This paper presents the reliability-based verification of the wall thickness for the TurkStream subsea pipelines. The collapse limit state was identified as the governing mode of failure, and was defined by a collapse prediction formula developed specifically for the TurkStream pipelines. The model was verified by full-scale tests from the test program, and then used to define the failure surface of the collapse envelope due to external pressure and bending. The probabilistic analyses resulted in reliability levels that exceed design code requirements. In addition, these analyses highlighted the need for certain criteria to be met during coated linepipe production. These requirements are summarized in this paper. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
