Unmanned Floating Platform Station-Keeping Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional long-term surveillance at sea involves expensive and hazardous human-occupied craft for detecting and intercepting unknown vehicles, with shore-based remote sensing providing limited observation capabilities and no effective means for unmanned surface vehicles to conduct extended-duration missions without manned assets.
Innovation Solution
An unmanned floating platform equipped with a hull, hangers, and a liquid storage compartment for fueling unmanned vehicles, enabling continuous surveillance and dispatch of unmanned vehicles for observation and interception, with optional sensor equipment and communication systems for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If human-occupied craft are used for surveillance, then observation capability and interdiction capability are improved, but operational cost and personnel risk increase
Solution Approach 1:
The unmanned floating platform performs surveillance, fuel storage, and vehicle deployment operations autonomously without requiring human operators on board. The system serves itself by maintaining station-keeping position, managing fuel reserves, and coordinating unmanned vehicle operations independently, thereby eliminating personnel risk while maintaining surveillance capability
Solution Approach 2:
The floating platform acts as an intermediary between shore-based command centers and remote surveillance targets. It provides a localized base that extends the operational reach of unmanned vehicles while maintaining continuous communication with shore-based control, enabling persistent surveillance without requiring manned assets
2Object-affected harmful factors
If unmanned vehicles are deployed for extended missions, then operational cost and personnel risk are reduced, but endurance and remote basing capability deteriorate
Solution Approach 1:
The floating platform pre-stores fuel in its liquid storage compartment before unmanned vehicles depart. This preliminary preparation allows vehicles to conduct extended missions beyond their normal endurance limits by refueling at sea, effectively extending operational duration without requiring larger vehicle fuel tanks or more frequent returns to base
Solution Approach 2:
The fuel supply system is segmented between shore-based storage and mobile floating storage. The floating platform carries a portable fuel supply that can be transferred to unmanned vehicles at sea, separating the large-scale fuel storage function (performed by shore facilities) from the mobile refueling function (performed by the floating platform), thereby enabling extended operations
3Object-affected harmful factors
If shore-based remote sensing is used, then operational cost is reduced, but observation capability and response time worsen
Solution Approach 1:
The floating platform transitions the surveillance function from a two-dimensional shore-based radar system to a three-dimensional mobile platform positioned in the maritime domain. This dimensional shift allows the platform to physically relocate closer to surveillance targets, dramatically improving observation capability and response time while maintaining the cost benefits of unmanned operation

Function Achieved in This Case
The solution provides cost-effective, low-risk continuous surveillance and interception capabilities, expanding the safety perimeter around fleet assets and enabling persistent monitoring with minimal resources, reducing operational costs and personnel risks.
Implementation Method 1
The hull has a submerged portion and a floating portion. The liquid storage compartment supplies fuel to the on-board equipment and to the unmanned vehicle. For static stability, the compartment is disposed in the submerged portion.

AI summary
An unmanned floating platform is provided for continual surveillance at a station-keeping position at sea. The platform is equipped to dispatch an unmanned vehicle to conduct at least one of observation and rendezvous. The platform includes a hull, first and second hangers, and a liquid storage compartment. The hull has a submerged portion and a floating portion. The first hanger is equipped for stowing, deploying and retrieving a self-propelled unmanned vehicle and is substantially disposed in the floating portion. The second hanger houses equipment for electrical power and on-board functions. The liquid storage compartment supplies fuel to the on-board equipment and to the unmanned vehicle. For static stability, the compartment is disposed in the submerged portion. The platform may also include a superstructure for housing sensor equipment. The superstructure can be disposed above at least one of the first and second hangers. The second hanger may additionally house a tetherable observation aerial post.
