Offshore Fish Processing Structure for Fresh Food Supply at Sea
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an offshore structure system and method that can quickly manufacture and supply food, such as bread or sweets, using fresh fish from fishing vessels at sea to meet the nutritional and taste demands of consumers, while addressing issues of fish spoilage during distribution and the long duration of fishing trips.
Innovation Solution
An offshore structure system comprising a loader, classification sensor, fishmeal producer, collagen producer, dough maker, and food producer, which processes fish into fishmeal and collagen, mixes with additives, and heats the dough to produce food, utilizing sea wind or solar heat for drying, and includes a fertilizer producer for waste utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If fish are dried and distributed to consumers, then fish can be preserved and transported, but the fish runs rancid easily during distribution and consumer taste cannot be satisfied
Solution Approach 1:
The patent applies preliminary action by processing fish into fishmeal and collagen extracts before distribution. The fish is dried, ground into meal, and extracted with solvents to create stable, shelf-ready products that won't spoil during transport. This preprocessing ensures food quality is maintained throughout the distribution chain.
Solution Approach 2:
The patent changes the physical and chemical parameters of fish through drying (removing moisture to prevent spoilage), grinding (changing particle size to meal), and solvent extraction (isolating collagen). These parameter transformations create products with improved stability and extended shelf life while maintaining nutritional value.
2Productivity
If fishing vessels spend long time at sea, then they can catch more fish, but it becomes difficult to secure food for the crew
Solution Approach 1:
The patent applies self-service by enabling fishing vessels to process their own catch into food products at sea. The vessel uses its own fishing equipment to catch fish, then processes the fish into meal and collagen extracts that serve as food for the crew. This self-sufficiency eliminates the need for separate food supply chains.
Solution Approach 2:
The patent applies multi-functionality by creating a system where the fishing vessel performs both fishing and food production functions. The same vessel that catches fish also processes it into consumable products, making the system versatile and self-contained for extended operations at sea.
3Reliability
If fish are processed quickly to prevent spoilage, then food quality is maintained, but the processing system becomes complex
Solution Approach 1:
The patent applies segmentation by dividing the fish processing into distinct functional modules: drying unit, grinding unit, extraction unit with solvent circulation. Each module performs a specific function and can operate independently, making the overall system manageable despite its complexity. The segmented approach also allows for easier maintenance and operation.
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 produces high-quality fishmeal, collagen-based food, and fertilizers directly at sea, supplying fresh food to fishing vessels and land consumers, while minimizing energy consumption and ensuring food quality.

AI summary
Proposed is an offshore structure system, the offshore structure system comprising: a loader configured to load fish caught from a fishing vessel on an offshore structure; a classification sensor configured to classify the fish by type; a fishmeal producer configured to produce fishmeal from the first kind of fish classified by the classification sensor; a collagen producer configured to produce collagen from the second type of fish classified by the classification sensor; a dough maker configured to generate fish meat dough by adding additive to the fishmeal and the collagen; and a food producer configured to produce food by heating the fish meat dough.
