Fuel Cell Ship Tank Compartment Layout for Hydrogen Leak Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel cell ships lack adequate safety measures to mitigate risks associated with combustible fuels like hydrogen, particularly in preventing theft and ensuring safe storage and handling.
Innovation Solution
The fuel cell ship design includes a tank compartment for the fuel tank, positioned below the deck and separated from other compartments, with dedicated ventilation and detection systems to monitor and control fuel gas leaks, and a compartmentalized layout to minimize risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fuel tank is placed in a shared compartment with other equipment, then the device complexity is reduced, but the safety risk increases due to potential fuel leaks affecting other systems
Solution Approach 1:
The ship is divided into separate compartments, with the fuel tank placed in a dedicated tank compartment that is separated from the engine room and other equipment areas by bulkheads. This segmentation isolates the fuel storage function, preventing fuel leaks from affecting other systems while maintaining overall system reliability.
2Object-affected harmful factors
If active hydrogen discharge is implemented to prevent theft, then the anti-theft capability is improved, but the safety risk increases due to potential hydrogen accumulation and explosion hazards
Solution Approach 1:
The fuel tank is extracted and placed in a separate tank compartment isolated from the engine room and other equipment by bulkheads. This spatial extraction ensures that even if active hydrogen discharge occurs for theft prevention, the hydrogen is contained within the dedicated compartment and cannot accumulate in areas with ignition sources, thereby eliminating the explosion hazard while maintaining theft prevention capability.
3Ease of operation
If the fuel tank is positioned above the deck for easy access, then the ease of operation is improved, but the safety decreases due to higher risk of accidental damage and exposure
Solution Approach 1:
Instead of positioning the fuel tank above the deck for easy access, the tank is placed in a dedicated compartment below the deck level. This dimensional change prioritizes safety by protecting the fuel tank from accidental damage and exposure, while the compartmentalized design with dedicated ventilation and detection systems ensures that fuel management operations can still be performed safely through controlled access points.
