船舶坐底运动姿态监测系统研发及应用

Development and application of motion attitude monitoring system for ship sitting on the bottom

在船舶坐底过程中需要重点关注船舶的运动姿态变化,以便及时对船舶状态做出调整,保障船舶坐底安全。针对船舶坐底过程,自主研发了运动姿态监测系统,对船舶的六自由度姿态、三轴速度、三轴加速度、船舶四个角点的垂向速度和船底距海床的距离等参数进行监测。结果表明:运动姿态监测系统在船舶坐底过程中能够实时监测船舶运动姿态关键参数变化情况并进行安全提示,实现了对船舶坐底运动姿态的全程监测功能。

During the process of ship sitting on the bottom,it is necessary to pay special attention to the motion attitude changes of the ship in order to make timely adjustments to the ship′s state and ensure the safety of ship sitting on the bottom.An independent motion attitude monitoring system has been developed for the process of ship sitting on the bottom,capable of monitoring six degrees of freedom attitude,three-axis velocity,three-axis acceleration,vertical velocity for the four corners of the ship,and the distance from the ship′s bottom to the seabed.The results show that the motion attitude monitoring system can monitor the changes in key parameters of ship motion attitude in real time,providing safety reminders during the process of ship sitting on the bottom,and achieving the full monitoring function for ship motion attitude during sitting on the bottom.
