Book Review by: Sonu Chandiram

This book informs us of the scenarios that happen when two natural and material elements – the sea and the soil – interact with one other element – a man-made structure.

The goal is to build structures that will be stable enough to fully withstand the pressures of the movements of water such as waves, as well as the frequent instability of the seabed (as a foundation for the structure) due to sea currents beneath the water surface.

The author Dong-Sheng Jeng provides various scenarios that can destabilize the man-made structures, and what needs to be done to prevent each type of occurrence, accompanied by a full complement of updated mathematical and physical formulas. He then places the models in context with industry-relevant examples.

He also presents recent technological advances that have come about along with all the relevant math and physics, that make the tasks of stabilization easier to handle. He discusses the key equations involved, as well as the strengths and challenges of each one.

This book consists of eight chapters we list below to give you a brief perspective:

  1. Overview
  2. Basic Seabed Mechanisms
  3. Soil Response in Marine Sediments Under Combined Loading of Waves and Currents
  4. Integrated Models of Wave-Seabed Interactions around Caisson-Type Breakwaters
  5. Mechanics of Weave-Seabed-Pipelne interactions
  6. Three-Dimensional Models of Wave-Seabed Interactions around Breakwater Heads
  7. Seabed Instability around Offshore Wind Turbine Foundations
  8. Physical Modeling: One-Dimensional Compressive Tests

Let us take a look at the main topics presented and discussed in chapter 2 entitled Basic Seabed System:

  • 2.1 – Introduction
  • 2.2 – Wave Models
  • 2.3 – Wave-Induced Oscillatory Soil Response
  • 2.4 – Wave-Induced Residual Soil Response
  • 2.5 – Progressive Nature of Wave-Induced Liquefaction
  • 2.6 – Solitary Wave Over a Sloping Seabed
  • 2.7 – Coupled Model for Wave-Seabed Interactions

This is an excellent book for those involved in marine engineering and construction that design and install structures such as offshore platforms for gas and oil exploration and extraction, submarine pipelines, wind power structures, and similar projects.
