As reported, the burial depth of three submarine pipelines in Tangshan Sea Area, i.e. NB35-2CEP to QHD32-6SPM, QHD33-1WHP to QHD32-6WHPC and NB35-2WHPB to NB35-2CEP are not deep enough so part of the submarine pipelines came out of the bottom of the sea, relevant issues are hereby announced as follows:

  1. Submarine Pipeline Route:
    1. Route of Submarine Pipeline NB35-2CEP to QHD32-6SPM is linked by following 4 points in order:

      A) 39°04′14.27″N,118°54′58.02″E;

      B) 39°04′31.89″N,119°12′09.56″E;

      B) 39°04′14.27″N,118°54′58.02″E。

  2. Cautions:
    1. Coping down, drilling, piling, dropping anchor, dragging anchor, bottom trawling, standing net, cultivation or other offshore operations that might damage the safety of the submarine pipelines are forbidden in the area within a range of 500 meters from both sides of the submarine pipeline route.
    2. Anchoring vessels nearby the submarine pipelines should strengthen duties and be cautious against touching submarine pipelines due to dragging anchors.
