Sargassum Sequestration via Hydrostatic Buoyancy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing sargassum in the Caribbean are expensive, disruptive, and ineffective as they rely on manual labor and machinery that is prone to damage, and do not address the root issue of sargassum accumulation in the ocean, allowing it to cause environmental and health problems when it makes landfall.
Innovation Solution
A method for sequestering sargassum by pumping it to a critical depth in the ocean where it becomes negatively buoyant and sinks, using vessels equipped with booms, funnels, and pumps to collect and transport sargassum to depths of 150-200 meters, preventing it from returning to the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual cleanup methods are used to remove sargassum from beaches, then sargassum can be removed from coastal areas, but the cost increases significantly and large amounts of manpower are required
Solution Approach 1:
The patent replaces manual mechanical cleanup operations with an automated pump-based system that uses hydraulic principles to collect and transport sargassum. The pump system mechanically extracts sargassum from water and transports it to disposal locations, eliminating the need for manual labor and significantly improving cleanup productivity while reducing operational costs
Solution Approach 2:
The invention employs a pump system that utilizes hydraulic pressure to collect sargassum from water bodies and transport it through hoses to designated disposal areas. This hydraulic mechanism enables efficient bulk removal of sargassum without requiring extensive manual intervention, thereby resolving the contradiction between effective sargassum removal and high productivity
2Productivity
If heavy-duty machinery is used for sargassum removal, then collection capacity increases, but the machinery is prone to damage and requires frequent maintenance
Solution Approach 1:
The patent modifies the operational parameters of the collection system by using a pump-based approach that operates at lower mechanical stress levels compared to heavy-duty machinery. The pump system can handle sargassum with varying buoyancy and density without requiring high-force mechanical components, thereby maintaining high collection capacity while improving machinery reliability and reducing damage frequency
Solution Approach 2:
The invention employs simpler, more robust pump components that are less susceptible to damage from sargassum's abrasive and corrosive properties. These components are designed to be more replaceable and maintainable at lower costs, effectively trading off the use of expensive, complex heavy-duty machinery for simpler, more reliable equipment that can withstand the harsh operational environment
3Object-affected harmful factors
If floating barriers are installed to prevent sargassum from reaching beaches, then sargassum interception is improved, but the barriers are extremely expensive and require constant maintenance
Solution Approach 1:
Instead of installing complex floating barrier systems that require constant maintenance and monitoring, the patent extracts sargassum directly from the water using mobile pump units. This approach eliminates the need for permanent barrier infrastructure, significantly reducing device complexity and maintenance requirements while maintaining effective sargassum interception and prevention of landfall
Solution Approach 2:
The invention employs dynamic, mobile pump systems that can be deployed and relocated as needed rather than static floating barriers. This dynamic approach allows flexible response to sargassum movements and accumulation patterns, achieving effective landfall prevention without the high complexity and maintenance burden of permanent barrier structures
4Object-affected harmful factors
If sargassum is collected and transported to landfills, then sargassum is removed from coastal areas, but methane emissions increase due to decay
Solution Approach 1:
The patent converts the harmful effect of sargassum decay into a beneficial outcome by implementing controlled decomposition through composting facilities. Instead of allowing uncontrolled decay in landfills that generate methane, the system processes sargassum into compost, transforming the harmful organic matter into a useful soil amendment while eliminating methane emissions and addressing coastal sargassum removal

AI summary
Buoyant matter, and particularly biomass such as seaweed, is sequestered deep in a body of water, fey causing the matter to lose it buoyancy and sink and remain sunk for an extended period. In some examples, the matter is pumped to below a depth at which is loses its natural buoyancy as a result of the ambient water pressure resulting in it naturally sinking to the bottom.
