摘要
由于水下生产设施位于水下,如果附近有渔业活动,渔具系统可能会与水下生产设施发生碰撞,导致水下生产设施保护架被船拖坏并引起管道、脐带缆等损伤。主要针对东海海域采用理论和数值分析方法建立了在一定航速、缆索长度、网具类型等控制参数下的渔具系统运动轨迹的数值模型,并与相关文献的数值结果进行了对比,验证了本文数值模型和计算方法的正确性,最终根据我国东海海域实际水深及渔业情况,界定出该海域以水下生产设施为中心的渔船安全作业半径不得小于350 m。
The subsea production system is located underwater. Fishing gear system may collide with subsea production system. The fishing vessel will destroy the valve protection frame and result in pipe damage. Therefore, a numerical model of fishing gear trajectory with control parameters of vessel speed, cable length, type of nets, etc has been established by using theoretical and numeri- cal methods for East China Sea. Compared with the results in some literatures, the numerical model and calculation method are confirmed. Ac- cording to the water depth and fishery situation in East China Sea, it is determined the radius of fishing vessels safe operation zone at the center of subsea production system should not less than 350 m.
