Anchor risk evaluation program, anchor risk evaluation system, and anchor anchor risk avoidance system

摘要

Problem to be solved: to provide an anchor anchor risk evaluation program, etc., which accurately evaluates the risk of the anchor anchor by accurately estimating the ship motion of the ship anchoring at the time of anchor anchor and anchor staying at the time of rough weather.Computer 10DataDriving method dataAnchor and anchor chain dataMeteorological and Oceanographic DataThe data acquisition step S1 for obtaining the anchor data pertaining to anchor and anchorAn estimation of the external force acting on a ship using the ship data and meteorological and Oceanographic DataA driving force estimation step S3 for estimating the driving force of a ship using ship data and driving means dataAnchor chain and anchor chain dataAnchor dataEstimation of the anchor chain tension estimated by using the ship's attitude and wake at one time step and one stepApplication of the external force, the driving force, and the tension of the anchor chain to the equation of motion to calculate the attitude and the wake of the ship.An output step S11 for outputting the calculated attitude and wake is executed.Diagram
