  3. Mobile Safe Operation zone:
    Water area in the above work site within 300 meters in front of and behind the cable laying ships, "Jian Lan 1" and "Chang Yan 19" respectively, and within 300 meters from the port and starboard side of the above vessels respectively.
  4. Work mode:
    The cable laying ships, "Jian Lan 1" and "Chang Yan 19" use two anchors mooring in the above work site and carry out cable laying operations in the sequence of operation. During the operation, “Kang Nuo Tuo 7”, “He Xie Tuo 16”, “Kang Nuo 16”, “Kang Nuo 18”, “Zhong Nan 988” will carry out auxiliary works such as towing and security.
