FREQUENCY ANALYSIS OF FAILURES ON GAS PIPELINES OPERATING IN THE NORTH

Puyang river basin is located in the north central part of Zhejiang Province, which is one of the most important river basins in Zhejiang Province. The lower reaches of Puyang River are easily influenced by tide in Hangzhou Bay and flood in Qiantang River. When Puyang river floods, it often meets Fuchun River and floods occur at the same time. The flood discharge of Puyang river is blocked and the water level rises and rises, which makes the Puyang River vulnerable to disaster. Water level frequency analysis is the basis of Puyang river planning and flood control plan. The representative flood control water level stations of Puyang River include Zhuji station and wenjiayan station. The frequency analysis of these representative stations is helpful to determine the water level of these key nodes under different frequencies, and to provide basic data for accurate flood control of Puyang River and ensure the safety of flood control.

Australia's relative isolation and the harsh environment in Bass Strait have led to many innovations in offshore oil and gas developments. The initial developers were moving into frontier territory when Bass Strait was developed, with the harsh sea state and the water depths presenting major challenges. The original development of Bass Strait in the 1960s was tied to a wet gas pipeline philosophy, which was a novel step-out from normal industry practice. For example, the North Sea developments, which started shortly after Bass Strait, adopted dry gas export pipelines and required substantially larger platforms to process the gas for export. The cold waters of Bass Strait require an active hydrate management strategy and the success of hydrate inhibitors has been a key element in using wet gas pipelines. The initial development relied on methanol for hydrate inhibition, but this changed to a glycol-based hydrate inhibitor within 10 years of production start-up, due to challenges in the onshore production facilities. The use of mono-ethylene glycol for management of wet gas pipelines was demonstrated in Bass Strait. The success of the initial developments has given operators the confidence to pursue marginal field developments that rely on wet gas transport to the beach. The Minerva, Casino, Thylacine and Longtom gas field developments in Bass Strait have all adopted the same strategy, in part because of the confidence provided from operating the initial developments for many years.

New Settlements

The article analyses the settlement of the Tyumen Region from the perspective of the interaction between the traditional settlement scheme that has developed over the last four centuries, and a group of settlements, where oil pumping and/or gas compressor stations of main oil and gas pipelines are located and maintained. The genesis of this interaction revealed two main directions: eastern and northern. In the first case, the junction points of the Trans-Siberian Railway, which served as administrative outposts, initiated the process of forming agricul-tural, commercial and then industrial zones (and, accordingly, new settlements); the north direction reflects the main stages of Russia's advancement to the North, including the massive industrial development of a unique West-Siberian oil-and-gas province. The homogeneity of the considered settlements in terms the production, terri-torial and social aspects allows us to interpret them as a territorial and production cluster. The organising role of the pipeline transport network in the further development of this cluster is shown. Firstly, it contributed to the emergence of new settlements, and secondly, former small settlements turned into the nodal points of the trans-formed settlement scheme. The result of the cluster formation is correlated with the dynamics of the urbanisation process and is presented in the form of a framework for the development and settlement of the Tyumen Region and its scheme. The consideration of the subject matter is multidisciplinary in nature due to its complex and multi-aspect character. In this study, elements of various methods and approaches were employed: historical-geographical and economic-geographical when studying the genesis of the settlement structure; ethno-demographic when considering the processes of natural and forced migration; socio-cultural and economic-organisational when trying to create a sociocultural scheme of a territorial community.
