Abstract

The validation of a real-time control system for the deployment of submarine communication cables presented. The control system allows the user accurately control cable bottom slack and position the cable along a pre-planned route. The system was successfully used to lay an underwater acoustic tracking range for the US Navy. A total of eight, 40 mile long cables, each having eight in-line hydrophones and several repeaters were laid in water depths of 40 m to 1800 m off San Clemente Island, California. The hydrophones were placed within specific targets along the cable route despite multiple abrupt turns in the paths, and a fully functional acoustic range is now in place. The flexibility and accuracy of the system in controlling cable bottom slack and cable bottom placement are presented using data from this Navy cable lay. The importance of properly measuring drag coefficient and forecasting currents for deep ocean cable lays is also discussed. The cable deployment control system proved that it can provide proper ship and cable engine commands to recover from unexpected full ship stops and resume deployment operations with no adverse effects on the cable lay.<>

松弛电缆布放实时电缆布放控制系统的验证

介绍了一种用于海底通信电缆部署的实时控制系统的验证。控制系统允许用户精确控制电缆底部松弛，并沿着预先规划的路线定位电缆。该系统成功地用于为美国海军铺设水声跟踪范围。总共有8条40英里长的电缆，每条电缆都有8个直线水听器和几个中继器，这些电缆被铺设在加利福尼亚州圣克莱门特岛附近40米至1800米的水下。水听器被放置在电缆路线上的特定目标上，尽管路径上有多个突然的转弯，现在已经有了一个功能齐全的声学范围。通过这次海军电缆敷设的数据，说明了系统在控制电缆底部松弛和电缆底部放置方面的灵活性和准确性。讨论了正确测量阻力系数和预测海流对深海电缆敷设的重要性。事实证明，该电缆部署控制系统可以提供适当的船舶和电缆引擎命令，以从意外的全船停机中恢复并恢复部署作业，而不会对电缆敷设产生不利影响。
