According to the rapid growth of population and industrialization, humankinds in the 21th century are faced on the shortage crisis of spaces and resources.

Therefore, the ocean is spotlighted as an effective alternative for new space development. 

However, the ocean has environmental difficulties such as, high water pressure, tidal variation for sustainable and cost-effective development.

Especially, technical characterization on the ocean floor is insufficient. Thus, geotechnical simulation and characterization of the ocean geology is a prior requirement in the ocean engineering field.
