Drilling Vessels: Movement, Displacement and Holding

Abstract

The monograph considers the features of the dynamics of drilling vessels designed to work in the sea. The complex of theoretical studies included in the monograph is aimed at solving problems related to substantiation of features of dynamic positioning system of a drilling vessel, necessary for its operation in the open sea conditions.
The conditions for operation of the automatic position-keeping system of a vessel are determined by the wind and wave roughness and the allowable flow speed.
The proposed algorithms for solving problems of control of a drilling vessel represent a digital-analog complex, that is due to non-linearity of tasks being solved and the presence of logical conditions in the algorithms.
The control model developed by the authors provides the possibility of its technical implementation.
