某大型沉浮式深远海网箱压载水系统设计与试验OA
Design and experimental validation of ballast water system for a large-scale semi-submersible deep-sea cage
为提高深远海网箱应对极端天气的能力,依据规范要求对某深远海网箱进行了压载水系统设计,并在养殖海域进行了网箱沉浮试验,试验过程中采用倾角传感器与液位遥测换算两种方法记录网箱倾角.结果显示:网箱沉浮时间约 6h,满足设计要求;网箱沉浮速度与网箱截面积负相关,在截面突变处沉浮速度变化明显;网箱横纵倾测量最大值分别为-2.5°和1.25°,网箱横纵倾计算最大值分别为-1°和1°;沉浮试验中网箱倾角测量值与计算值的变化趋势一致性良好.通过沉浮试验验证了压载水系统的合理性,倾角传感器敏感程度更高,可用于网箱倾斜报警.双监测方案为深远海网箱的优化设计提供了高精度数据支持.
To enhance the cage's resistance to extreme sea conditions,a ballast water system was designed in compliance with regulatory requirements,and buoyancy tests were conducted at the farming site.During the trials,two methods-inclination sensor and liquid level telemetry conversion-were employed to monitor the cage's inclination.The results demonstrated that:The cage's buoyancy process lasted approximately 6 hours,meeting design specifications;Buoyancy speed exhibited a negative correlation with the cage's cross-sectional area,with pronounced velocity fluctuations observed at sectional transition points;The maximum measured horizontal/longitudinal angles reached-2.5°and 1.25°respectively,while calculated values peaked at-1°and 1°;The inclination data from both measurement methods showed consistent trends throughout the test.The ballast water system's performance was confirmed via buoyancy testing,where the inclinometer's enhanced sensitivity facilitated real-time net cage tilt detection.The dual-monitoring approach provided high-precision data for the optimization design of deep-sea cages.
