DEVICE FOR PREVENTING ENTANGLEMENT OF ANCHOR CHAINS FOR SHIP

摘要

PURPOSE:To prevent anchor chains from being entangled by calculating azimuths connecting a ship and two anchoring points and the azimuth of bow based on data from a ship position measuring device and a bow azimuth measuring device, and adjusting the position of said ship when these azimuths are above a defined angle. CONSTITUTION:A ship position measuring device 1 measures the position data of a ship using a radar, a loran C, an Omega, etc., while also measuring the data of bow azimuth of the ship using a gyrocompass, a magnetic compass, etc. And, relative angles between two anchoring points A, A' and the bow azimuth B of the ship are calculated based on these data. When the relative angles reach a defined value, a control signal is outputted to the driving part of the ship to adjust the position of a hull. When a ship is at anchor, a dangerous condition that can possibly cause the entanglement of anchor chains, can be accurately detected, preventing such a condition from taking place.
