This article is devoted to the construction of offshore pipelines, taking into account protection environment. Initially, information was provided on conditions pipelines. Then there a discussion about methods laying their pros and cons, therefore choice method, which economically viable takes We know that main factor in choosing any method submarine pipeline economic environmental factors. Und...

Indonesian Navy (TNI AL) is the main component for Maritime Security and Defence. Because of that, TNI AL needs Indonesian Warship (KRI) to covered Maritime area. The main requirement from KRI is fulfilled by demand. To pock of fuel demand from KRI at Naval Base, it needs a new pipeline of fuel distribution network system. The pipeline network system used for maximum lifetime must be protected ...

Economical design with sufficient fracture resistance is of high importance in any offshore pipeline projects. Using an Engineering Critical Assessment (ECA), alternate acceptance criteria for pipeline girth weld inspection can significantly reduce the cost of constructing of offshore oil and gas pipeline by minimizing unnecessary repairs. Offshore pipelines consist of short pipeline segments c...

Free-span occurs normally in a pipeline at uneven seabed, dynamic seabed and pipeline crossing. Free spanning in pipeline causes Vortex Induced Vibration (VIV) fatigue, fracture and bursting. In this paper, a pipeline located in South Pars Gas Field is assessed against local buckling and VIV fatigue using probability of failure theory based on the recommended methodology by Det Norske Veritas (...

Abstract The prevention of gas overrun in the panel is one key issues on green mining. In this paper, a physical goaf model was established based geological production conditions coal seam mine Henan Province, and combined drainage technology by burying spilling pipeline upper corner proposed. Fluent software used to simulate changes mass fraction flow field distribution when extracted from wit...

this paper presents a k- turbulence model for simulation of steady current and itsinduced vortex shedding caused by the presence of an offshore pipeline. performance of the modelaround a circular cylinder above a wall with gap to diameter ratios of 0.1, 0.35 and 0.5 underdifferent flow regimes with reynolds numbers of 1500, 2500 and 7000 is studied. the flow field iscomputed with solving the re...

Objectives: In this study, we intend to propose a network analysis-based pipeline for drug repositioning using social service data.Methods: We collected and analyzed 778 final posts on Cozaar-tab, representative antihypertensive drug, from (2008-2022) of Naver Cafe, the largest channel in Korea. For analysis, defined three filter dictionaries Cozaar-tab based WHO-ART, an international classific...

With the rapid growth of oil and gas storage, transportation, pipeline industries, it is necessary to improve construction process pipelines. By combining technical advantages horizontal directional drilling pipe jacking construction, direct laying method suitable for crossing in different strata gas, water conservancy hydropower, municipal industries due its less land, high speed, reversibilit...
