The tentative topics of symposium are as following. 

1. Engineering characteristics of marine soil.

   Conveners: Qing Yang( Yuxia Hu (

The engineering characteristics of marine soil are distinct from that of terrestrial soil due to its unique composition, fabric, and environment of sedimentation. The shore line deposits are sands on beaches and finer soil particles in lagoons and on tidal flats. The deep sea floor is covered mainly by brown clays and calcareous and siliceous oozes. Terrigenous deposits are derived from land; whereas, pelagic sediments settle from the water alone and contain the shells and skeletal remains ofmarine organisms and plants.

Ø Geotechnical properties of marine soil

Ø  Micro-structures of marine soil

Ø  Constitutive relationship of marine soil and numerical modeling

Ø  Calcareous sand/coral sand and challenging soil

2. Regional engineering geology & Offshore geohazards.

    Conveners: GuoxingChen ( QichengSun ( Urgeles (

Offshore geohazards are found in most parts of the ocean and are always related to geological conditions and geological processes, either recent or past. Important offshore geohazardsincludeslope instability, submarine mass movements(e.g.submarine landslide), pore pressure phenomena (e.g. seabed liquefaction) and seismicity.

Ø  Investigation and evaluation of engineering geological conditionsin typicalsea

Ø  Submarine landslide, turbidity current and its complication of tsunami

Ø  Submarine earthquake and earthquake tsunami

Ø  Seabed liquefaction

Ø  Other offshore geohazards

3. Coastal engineering geology.

 Conveners: Yu Huang (  Ping Yin ( Jin Sun (

With the rapid development of coastal resource exploitation and utilization worldwide, coastal engineering geology has become a key component in human activities.The session aims to provide a forum for engineering geologists who play a pivotal role in investigating, managing, using, exploiting, designing and protecting the coastal domains so that they can share their overall views, creative ideas and advanced knowledge.

Ø  Coastal erosion and protection

Ø  Engineering geological problems in land reclamation

Ø  Coasts at threat: causes and consequences of coastal settlement

Ø  Geodisaster prevention and mitigation in coastal regions

4. Marine engineering geological survey technology and data analysis.

Conveners: Jinhui Li ( Maarten Vanneste( Ting Zhang (  Tobias Mörz(

The technology and model of the seabed stratigraphy including quantification of engineering parameters for relevant layers is essential for engineering design of offshore structures. Desk study, geophysical investigation, and geotechnical investigation are the three stages involved in a complete site characterization. The theory behind the various techniques of geophysical and geotechnical measurements and interpretation of data is complex, requiring further development in the technology and the data analysis.

Ø  Marine geophysical survey

Ø  In-situ and laboratory testing

Ø  Long-term field observation

Ø  statistical characterisation of geotechnical data

5. Submarine soil-structure interaction.

   Conveners:Lizhong Wang (  Dong Wang ( Haixiao Liu (

Submarine soil-structure interaction refers to the behaviors of offshore foundations and pipelines in shallow or deep waters. This is one of the most active areas in offshore engineering, providing geological and geotechnical solution to the developments of oil and gas extraction and wind farms. The stability and displacements of a variety of structural elements during installation and daily operation stages are covered in this session.

Ø  Installation and operational safety of spudcan footings for jack-up rigs

Ø  Penetrations and pull-out capacities ofanchors used in shallow and deep waters

Ø  Displacements and consolidations of subsea foundations

Ø  Pipe-soil interaction

6. Marine engineering geology in offshore new energy development.

Conveners: Shaoli Yang (  Mingyuan Wang (

Marine engineering geology plays an important role in offshore new energy development.Offshore wind power or offshore wind energy refers to the construction of wind farms in bodies of water to generate electricity from wind.A significant growth area in the renewable energy is wind power at sea. Offshore wind is a source of stable, inexhaustible and clean energy. Besides, the enormous amounts of methane hydrate under the ocean and beneath arctic permafrost represent an estimated 53% of all fossil fuel (coal, oil, natural gas) reserves on earth, about 10,000 gigatons. Gas hydrates are potential energy resource.

Ø  Offshore geological site investigation related to new energy development

Ø  Foundation design for offshore windfarm

Ø  Offshore soil parameters related to new energy development

Ø  Engineering geological challenges related to new energy development

Ø  Case studies in offshore new energy development
