Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack effective solutions to mitigate the devastating effects of storm surges and tsunamis on coastal communities, as current methods fail to adequately disrupt or inhibit the destructive impact of these ocean phenomena.
Innovation Solution
The implementation of an offshore system that generates artificial Taylor columns by strategically placing cylindrical solid bodies within the path of oncoming storm surges or tsunamis, utilizing the warm water flow from an Ocean Thermal Energy Conversion (OTEC) system to create a whirlpool that disrupts the hydrodynamic flow and mitigates the damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If cylindrical solid bodies are placed offshore to generate Taylor columns, then the ability to disrupt hydrodynamic flow and mitigate storm surge/tsunami effects is improved, but the device complexity and installation requirements increase
Solution Approach 1:
The system divides the coastal protection function into multiple cylindrical solid bodies (Storm Surge Mitigation Structures or SSMS) distributed offshore. Each cylinder independently generates Taylor columns that collectively form a protective barrier, allowing the system to disrupt storm surge and tsunami flows without requiring a single complex massive structure.
Solution Approach 2:
The cylindrical structures serve multiple functions: they generate Taylor columns for storm surge mitigation, provide OTEC warm water intake, and create whirlpool effects. This multi-functionality reduces the need for separate structures for each purpose, thereby managing complexity while achieving multiple protective and energy generation goals.
2Reliability
If a series of cylindrical bodies are strategically placed to create Taylor columns, then the disruption of oncoming wave action is improved, but the installation and maintenance difficulty increases
Solution Approach 1:
The system transitions from traditional coastal defense (building barriers at the shoreline) to offshore deployment of cylindrical structures in the open ocean. This dimensional shift allows structures to be installed in deeper water where installation equipment is more readily available and maintenance can be performed by vessels, avoiding the need for complex shore-based installation infrastructure.
3Object-affected harmful factors
If OTEC warm water flow is utilized to create whirlpool and generate Taylor columns, then the mitigation effectiveness is improved, but the system complexity and energy requirements increase
Solution Approach 1:
The system merges storm surge mitigation with OTEC warm water intake operations. The same cylindrical structures that generate Taylor columns also serve as intake structures for OTEC, combining two functions into a single integrated system. This reduces overall complexity compared to having separate mitigation structures and separate OTEC intake systems.
Solution Approach 2:
The system converts the strong oncoming warm water flow (which could potentially cause operational issues) into a beneficial whirlpool effect that enhances Taylor column generation. The kinetic energy of the incoming flow is harnessed to create the rotational motion needed for effective storm surge mitigation, turning a potential challenge into an operational advantage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively inhibits the destructive effects of storm surges and tsunamis by creating a series of Taylor columns that disrupt the wave action before it reaches the shore, leveraging the OTEC system's warm water flow to enhance the disruption and mitigate damage to coastal infrastructure.
Implementation Method 1
A Taylor column is a fluid dynamics phenomenon whereby rotating fluids that are perturbed by a solid body tend to form columns (i.e. Taylor columns) parallel to the axis of rotation. With a Taylor column, a slowly moving object (in rotation) behaves nearly as a solid cylinder extended parallel to the rotation axis.
Implementation Method 2
An object moving parallel to the axis of rotation in a rotating fluid experiences more drag force than what it would in a non-rotating fluid.
Implementation Method 3
Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity.
Implementation Method 4
OTEC uses the ocean's warm surface water with a temperature of around 25° C. (77° F.) to vaporize a working fluid, which has a low-boiling point, such as ammonia. The vapor expands and spins a turbine coupled to a generator to produce electricity.

AI summary
Offshore apparatus generating artificial Taylor columns for the purpose on interfering with oncoming storm surge and/or tsunamis. A series of solid bodies are anchored relative to the ocean floor to provide structures capable of generating Taylor columns in response to water flow and/or currents. The strategic placement of a series of cylindrical bodies creates a corresponding series of Taylor columns in response to hydrodynamic flow, such as current flow or tsunami related flow. The presence of a series of strategically located Taylor columns is intended to inhibit or disrupt the devastating effects of storm surge and/or tsunamis.
