Technical Research on Engineering Ships Based on Exploration Geological Conditions

Abstract

As the main ship type for offshore oil and gas field exploration, the comprehensive geological survey ship has multiple functions such as drilling and sampling, marine hydrological survey, and seabed topography and geomorphology survey. The paper briefly introduces the main technical features, general layout features, ship performance and ship positioning system design of a comprehensive geological survey ship. To improve comfort, the ship optimized the layout of the superstructure. At the same time, the positioning and operation of ships at sea are affected by the disturbance force of the marine environment, and the mathematical model of the dynamic positioning system controller is established. The system uses an active disturbance rejection controller to observe the ship’s motion status and the total disturbance of the power system in real time, and uses nonlinear feedback to compensate according to the system disturbance.
