  3. Work mode: work boat “KDDI OCEAN LINK” (Chinese name: 海联; Nationality: Japanese; LOA: 133.2m; Molded breadth: 19.6m) will detect the fault location, salvage and cut off the defective cable, splice, lay and repair the cable, bury and repair the cable along route of S3 of the NCP International Submarine Cable in the work site. During the operation, the navigation speed of the work boat is relatively slow.
  4. Cautions:
    1. The work boat should exhibit regulated lights and shapes, when dropping anchors, display visible signs at day and flash lights at night towards where the anchor chains enter the waters and keep AIS normally open.
    2. The work boat should strengthen watch on VHF16, improve the dynamic notification and take the initiative to contact the passing vessels.
    3. Vessels passing the work site should keep a distance of more than 500 meters with the work boat, sail cautiously and pay attention to the avoidance.
    4. Irrelevant vessels should not drop anchors and carry out operations in the work site without permission.
    5. The operation should be suspended when the force of wind is over the scale of 7 or the visibility is under 1nm.
