  6. Cautions:
    1. The workboats should display regulated lights and shapes in obvious places, visible marks should be displayed at day and lights should be irradiated at night towards the direction where the anchor cables are dropped in water. AIS should be kept normally open;
    2. The workboats should keep watch on channel and keep proper lookout;
    3. The vessels other than the workboats should try to avoid entering the worksite;
    4. Other vessels passing near the worksite should sail cautiously, keep a safe distance with the workboats and contact the workboats in advance if necessary;
    5. The operation should be suspended in case of bad weather in order to ensure the safety of the workboats.
