Fishing off season of the East China Sea is over and the fishing season has commenced, a large number of fishing boats will operate or sail in the East China Sea. Passing vessels should strengthen lookout and use good seamanship to avoid accidents.

  1. Fault Emergency Repair on S4 of the TPE Submarine Optical Fiber Cables in the East China Sea

(MSA Translation)

HHH(2019) No.410

China MSA 9 September 2019


  1. Work duration: 8 September 2019 – 7 December 2019, day-night operation.
  2. Work site: water areas outside the East China Sea of Changjiang Estuary, bounded by the following six points in order:

    A: 31°21′37.50″N/122°35′24.87″E;

    B: 31°19′27.62″N/122°35′24.31″E;

    C: 31°19′21.69″N/122°47′36.43″E;

    D: 31°11′22.55″N/122°53′51.58″E;

    E: 31°12′35.35″N/122°55′56.71″E;

    F: 31°21′32.19″N/122°49′27.90″E.

  3. Work mode: cable laying ship “CS FU AN” (LOA: 141.5m, molded breadth: 19.4m) 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 S4 of TPE submarine optical fiber cable in the work site. During the operation, “CS FU AN” will not drop anchors and will adopt dynamic positioning and her navigation speed is relatively slow.
  4. Cautions:
    1. The work boat should exhibit regulated lights and shapes in obvious places day and night and keep AIS normally open.
    2. The work boat should strengthen lookout and 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 safety distance with the work boat, sail cautiously and pay attention to the avoidance.
    4. The operation should be suspended when the force of wind is over the scale of 7 or the visibility is under 1nm.

      A: 38°37′37.290″N/118°59′00″E;

      B: 38°37′46.953″N/119°17′19.914″E;

      F: 38°34′15″N/119°07′00″E;

      E: 38°34′15″N/119°01′45″E;

      G: 38°32′00″N/119°07′00″E;

      F: 38°34′15″N/119°07′00″E;

    3. Work Area III: water areas bounded by the following 4 points:
    4. C: 38°30′27″N/119°17′26.072″E;

      D: 38°30′27″N/118°59′00″E;

      H: 38°32′00″N/119°01′45″E;

      G: 38°32′00″N/119°07′00″E;

    5. Work Area IV: water areas bounded by the following 4 points:

      A: 38°37′37.290″N/118°59′00″E;

      E: 38°34′15″N/119°01′45″E;

      H: 38°32′00″N/119°01′45″E;

      D: 38°30′27″N/118°59′00″E.

  4. Workboat: “Hai Yang Shi You 751”, “Rui Yuan 166”, “Xin Ye 241”, “Hai You Kan 1” and “Hai Tong Tuo 168”.
  5. Signals: Workboats should exhibit shapes of “Ball-Diamond-Ball” and hang towing flag at day and display lights of “Red-White-Red” at night
  6. Cautions: Workboats should keep watch on VHF 16; Workboats should pay attention to the movements of passing vessels constantly and contact passing vessels in advance. Passing vessels should avoid the work site where the operation is in progress.

  5. Coordinate System: 2000 National Geodetic Coordinate System (equal to the World Geodetic System WGS-84 in navigational purposes)
  6. Cautions:
    1. Passing vessels should strengthen contact with the workboats through effective communication methods such as VHF;
    2. Passing vessels should timely amend the sea chart and mark the work sites on the same;
    3. Passing vessels should ensure the seaworthiness of the vessels and the competence of the crew and strengthen duties;
    4. Navigating crew should use safe speed and sail cautiously.
    5. Irrelevant vessels are forbidden to enter into the work site.
