Abstract:

В статье описываются основные этапы построения укрупненной математической модели заводского изготовления металлоконструкций стационарных глубоководных оснований морских платформ для добычи нефти и газа. На основе полученной модели разработана укрупненная методика, предназначенная для расчета трудоемкости и себестоимости заводского изготовления стационарных глубоководных оснований на ранних стадиях вариантного проектирования. У статті описуються основні етапи побудови збільшеної математичної моделі заводського виготовлення металоконструкцій стаціонарних глибоководних основ морських платформ для видобутку нафти і газу. На основі отриманої моделі розроблена методика, призначена для розрахунку трудомісткості і собівартості заводського виготовлення стаціонарних глибоководних основ на ранніх стадіях варіантного проектування.

Description:

During first stage of design of any new construction forms of the jackets of the deep-water platform for oil and gas recovery designer has not detailed information about many parameters of such jackets. Usually he has only most general information, such as: the weight of this system, general amount of the linear elements, joint connections and other. Consequently he has not possibility to realize direct and detailed calculation of real price of fabrication and installation for every variants of developed jackets. And using of any computers program also is impossible, because for realization their algorithms we need very detailed information concerning many jacket’s parameters. But creators of different system of jackets have necessary to select most effective (in economic sense) variant of the metal structures even during early stage of creation. Therefore they need such type of methodic for analyzing of economic efficiency, which have very simple entrance parameters. This idea (for usual metal structures) was suggested by professor J.M. Lickhtarnickoff and he was founder of domestic scientific school of economic analyzing of metal structures. And the suggested method, based on the simple mathematic model of plants fabrication of such specific metal structures, is the next step of development of this school. For creation of this model was necessary to describe (mathematically) full technological process of fabrication of all elements of the jacket at the real plant. For this goal the Azerbaijan’s (in Baku) plant of fabrication of the deepwater metal structures was selected. Most modern technology of fabrication of different type jackets for deep-water platform was realized at this plant. During several years the detailed mathematical description of all technological processes and operation was created. In the article the basic stages of creation of the integrated mathematical model of factory manufacturing of metal structures of the jackets of the stationary deep-water platform for oil and gas recovery are described. On the basis of the received model the integrated technique intended for calculation of labour placing and the prime cost of factory manufacturing of the jackets of the deep-water platform at early stages of alternative designing is developed.
