![]() On this purpose, Nord Stream pipeline system is provided with a safety instrumented overpressure protection system, namely Pressure Safety System (PSS), which continuously monitors pipeline inlet and outlet pressures and automatically closes the pipeline inlet shut-down valves in case pressure set points are reached. The reference code for Nord Stream Project design (DNV-OS-F101) allows a pipeline to be divided into segments with different design pressures and without physical barrier (like shut-down valves) between the segments, provided that there is an adequate system to protect the pipelines from overpressure. Pipeline, line of pipe equipped with pumps and valves and other control devices for moving liquids, gases, and slurries (fine particles suspended in liquid). For example, a lot of crude oil is exported from Saudi Arabia to. This requires inventory visibility knowing when to order, how much to. The goal of inventory management is to have the right products in the right place at the right time. Pipeline inventory is anything thats in the pipeline of the supply chain and hasnt yet reached to its final destination. Since the inventory is in-transit it is also called pipeline inventory and believe it or not it is a crucial part of inventory management. Inventory management, a critical element of the supply chain, is the tracking of inventory from manufacturers to warehouses and from these facilities to a point of sale. ![]() ![]() This was based on technical and economical evaluations of pros and cons with respect to: Transit inventory as the name suggests is the inventory that has been shipped by the seller but has not yet reached the buyer’s destination. ![]() Specific requirements during pipeline installation and pre-commissioning activities.ĭuring the optimisation of the stepwise design pressure, it was enhanced the no-need of mid-way gas compression and relevant intermediate service platform (along the pipeline route). Thermo-hydraulic and mechanical analyses.Ĭonsiderations about steel pipe procurement. In order to maximise the cost saving of the overall EPCI project, the number and the extension of the pipeline segments and the relevant design pressure values have been optimised in the Nord Stream Project taking into account the results of: Therefore the pipeline can be mechanically sized with reference to different design pressures, stepwise decreasing while moving from upstream towards downstream end, which consequently allow decreasing the pipeline steel thickness. The design pressure segmentation concept, already adopted in long distance large diameter Norwegian trunklines to Germany (Europipe II) and to the UK (Langeled), is based on the fact that the downstream part of a long transmission pipeline never experiences pressures close to the values required at export point. In presence of state-of-the-art control system and rational operational strategy, the long distance and the significant pressure drop involved in the Nord Stream Project suggested an offshore pipeline designed with design pressure segments, with the aim to minimise the steel demand. ![]()
