Method of determining the trajectory of seismic equipment in the stationary character of sea towing

Abstract

Over the past 50 years, the search for natural gas reserves to meet the needs of enterprises and farms has become more and more relevant. The main method of finding mineral deposits is seismic exploration. In connection with the reduction of resources on land, seismic exploration in the sea is promising, as evidenced by the high rate of development of marine seismic technology. And modern technologies in the field of seismic exploration have ensured the popularity of methods of searching for minerals both at sea and in the world as a whole. Since determining the trajectory of the movement of seismic equipment during a fast maneuver relative to the main course is a complex multidimensional task, it is advisable to use an analytical method. The analytical method will allow to study the dynamics of seismic equipment taking into account a number of assumptions and limitations. A complex of special equipment is used for conducting seismic exploration at sea, which includes on-board and off-board components. Seismic equipment should be considered as a low-sea facility. During a quick maneuver, the seismic equipment moves to a certain angle instantaneously relative to the tug, as a result, the movement of the seismic equipment should be considered non-linear. As a rule, seismic equipment is placed on ships with a wide stern, on which the suspended equipment is fixed. The research in the article is based on the use of well-known methods of scientific research: system analysis, risk management theory, mathematical modeling methods for determining maneuvering and movement indicators of the tugboat and seismic equipment. The article improves the method of determining the trajectory of seismic equipment in the stationary mode of sea towing. The peculiarity of the method is the replacement of the movement of the towing vessel and the seismic equipment with their characteristic points, which makes it possible to consider the trajectory of the movement of the seismic equipment as a gentle curve with rapid and moderate changes in the course of the tug, to determine during towing various kinematic characteristics of the shallow-water object and to take them into account when developing the towing project for a variety of environmental conditions in compliance with shipping safety standards
