Type: Poster presentation
Session: Poster session
Based on the data from the multi-beam bathymetric survey, the sub-bottom profiling and the high-resolution multi-channel seismic exploration carried out in the Liwan 3-1 Gas Field, the first deep-water gas field in China, the geo-hazard types that have been identified along the deep section of the submarine pipeline route in the area studied include submarine canyons, seafloor landslides and collapses, paleo-coral reefs, seafloor sand waves and mega-ripples, shallow faults, submarine scarps, bluff and abrupt slope, debris flow deposits and turbidity current deposits. Of them, the seafloor landslides and collapses are well developed on the upper continental slope and the wall of submarine canyons, and the paleo-coral reefs, the submarine canyons, and the seafloor landslides and collapses are the potential geological risk factors for the layout and safe operation of the submarine pipeline.
