Abstract

The article is devoted to the scientifically substantiated selection of the main dimensions of the FPSO for operation as a pipe-laying vessel on the Caspian shelf at the initial design stages. On the basis of practical experience of using specialized pipe-laying vessels it is proposed to use universal subsea engineering support vessels (SESV). A system analysis was carried out and a mathematical model was formed to determine the main dimensions of SESV when using pipe-laying equipment. The influence of pipe-laying operations and equipment on the main dimensions of SESV was assessed. On the basis of the research, the previously developed nomogram of formation of main dimensions of SESV taking into account the use of pipe-laying equipment has been supplemented. The model of optimization of the main dimensions of SESV obtained on the basis of the performed dependences and the developed nomogram was formed. With the help of this model the parameters of SESV are determined for pipe-laying operations in the Caspian Sea basin.
