Dynamically positioned vessels/Суда с динамическим позиционированием

Издание на английском языке
This publication is devoted to dynamic positioning systems for ships and their application in the maritime industry. The book examines the purpose of DP, its advantages over manual control, the types of vessels and operations for which such systems are used, as well as the main control modes and position-holding principles. It describes DP system components, position measurement instruments, gyrocompasses, wind sensors, satellite, laser, hydroacoustic, and inertial systems. Special attention is paid to energy, propulsion, redundancy, DP classes, IMO, classification society, and industry organization requirements, as well as inspections, FMEA, annual testing, ship documentation, checklists, logbooks, and DP operator qualifications.
