Cleaning up the cable route is a time-consuming undertaking. First, the route is driven with metal detectors, and points are marked where the device deflects. A Remotely Operated Vehicle (ROV) is then launched into the water to identify the property. If the object is too deep in the ground for ROV detection, it is flushed free with a lance. The lance can penetrate up to six meters into the ground and blow air into the ground. If the object is then exposed, the diver goes into the water and hides it. The whole procedure is based on the assumption that it is remains of ammunition or duds because nobody should be harmed by carelessness.
Due to the predicted wave height of 2.60m for the next day, we drive back to the port. At this wave height, the recovery cannot continue, and we are waiting for better weather. This shows once again how dependent one is on the weather conditions when working offshore. It is better to go to the safe harbor once more than to endanger people or machines.
