Frontmatter

Chapter 1. Introduction

Abstract

The deepwater area is rich in oil and gas resources (Weimer et al. 2006; Zhang et al. 2007; Wu et al. 2009; Wu et al. 2018). However, deepwater oil and gas development has experienced many geological disasters that do not occur in shallow marine. Compared with land drilling, deepwater drilling is quite costly with high-risk.

Chapter 2. Submarine Landslides

Abstract

Submarine landslide is a downward movement of unconsolidated loose sediments or rocks.

Chapter 3. Gas Hydrate Disasters

Abstract

Marine gas hydrate hazards pose a significant threat to submarine pipelines, drilling platforms, and the near-shore environment. These hazards are caused by the formation and decomposition of hydrates, which are closely related to the environmental conditions in which they occur. Gas hydrate is a crystalline substance formed by natural gas and water under high pressure and low temperature. Gas hydrates are cage-like inclusions of gas and water molecules widely distributed in seafloor sediments along the continental slope, island slope, and marginal sea of the world ocean. These sediments occur in various forms, including layered, disseminated, and veined structures. With the increase of offshore drilling activities, the problem of geological hazards caused by gas hydrate has attracted more and more attention.

Chapter 4. Shallow Gas Disasters

Abstract

Shallow gas is generally referred to in the seabed below 1000 m of gas accumulation in the sediments. The components of shallow gas have simple structures, including methane, carbon dioxide, hydrogen sulfide, ethane, etc. Shallow gas has the characteristics of small molecule, small density, high buoyancy, low viscosity, small adsorption capacity, strong diffusion, easy to dissolve, volatile, and so on.

Chapter 5. Shallow Water Flow

Abstract

Shallow water flow (SWF) is a drilling disaster caused by overpressure driven upward flow of coarse sediments.

Chapter 6. South China Sea Earthquake and Tsunami Disaster

Abstract

Tsunamis are a series of giant waves with super-long wavelengths that occur and migrate through the ocean, most of which are caused by earthquakes (that occur below or near the ocean floor), underwater volcanic eruptions, landslides, and potentially coastal landslides.
