Autonomous Floating Platform for Continuous Maritime Surveillance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current maritime surveillance technologies, such as vessels, buoys, airplanes, satellites, and unmanned vehicles, fail to provide continuous, simultaneous surveillance of specific maritime areas including sea surfaces, aerial, and underwater spaces due to limitations in stability, maintenance requirements, cost, and coverage range.
Innovation Solution
An unmanned, autonomous floating platform anchored to the seabed, equipped with sensors like radars, lidars, sonars, and unmanned vehicles, which remains stationary to provide continuous surveillance of maritime areas, supporting energy autonomy and self-sustenance, and accommodating various surveillance systems for extensive coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vessels are used for maritime surveillance, then surveillance coverage can be provided, but high operational costs and frequent maintenance are required
Solution Approach 1:
The floating platform is equipped with autonomous power generation systems (wind turbines, solar panels) and self-sufficient life support systems, enabling it to operate indefinitely without external resupply or maintenance. The platform monitors and maintains its own systems, eliminating the need for periodic returns to base for maintenance and personnel renewal.
Solution Approach 2:
The invention extracts the surveillance function from mobile vessels and anchors it to a fixed floating platform. This separation allows the platform to remain permanently stationed at strategic locations, providing continuous surveillance without the logistical constraints of vessel operations.
2Ease of manufacture
If buoys are used for surveillance, then deployment is simple, but surveillance range is limited due to small size and low sensor mounting height
Solution Approach 1:
The platform utilizes vertical dimension by deploying a tall mast structure (40-50 meters) to elevate sensors above the sea surface. This vertical elevation overcomes the earth's curvature limitation and dramatically extends the surveillance range in the horizontal plane, allowing detection of objects at much greater distances.
Solution Approach 2:
The invention merges the simplicity of buoy deployment with the capabilities of a large stationary platform. The floating platform maintains easy deployment characteristics while incorporating extensive sensor arrays and unmanned vehicle operations, combining advantages of both simple and complex systems.
3Ease of manufacture
If buoys are used, then deployment is easy, but stability is poor due to undesirable movements and inclinations
Solution Approach 1:
The platform employs active stabilization systems that use sensors to detect motion and control systems to counteract it, effectively creating a stable reference frame despite the floating environment. This allows the platform to maintain operational stability comparable to land-based systems.
4Speed
If airplanes are used for surveillance, then mobility is achieved, but continuous fixed-location surveillance cannot be provided
Solution Approach 1:
The invention extracts the surveillance function from mobile aircraft and anchors it to a fixed floating platform. This separation allows the platform to remain permanently stationed at strategic locations, providing continuous surveillance without the logistical constraints of aircraft operations.
5Area of stationary object
If satellites are used for maritime surveillance, then broad coverage is achieved, but underwater surveillance capability is lacking
Solution Approach 1:
The floating platform serves as a universal surveillance hub capable of detecting objects across multiple domains: air (radar, electro-optic), surface (visual, radar), and underwater (acoustic, optical). This multi-functional capability allows a single platform to replace multiple specialized systems.
6Area of stationary object
If satellites are used, then broad coverage is achieved, but stable positioning above a region of interest cannot be maintained
Solution Approach 1:
The platform uses anchoring systems with counterweights and tensioning mechanisms to resist environmental forces (waves, currents, wind) and maintain a stable position. The anchoring system compensates for the floating nature of the platform, providing position stability comparable to land-based installations.

AI summary
An unmanned, autonomous, self-sustaining and self-repairable floating platform which is positioned at a fixed location within the sea, capable of constantly monitoring, without having to be removed, a specific maritime zone including a sea surface area and the aerial and underwater space pertaining to this sea surface area, the platform comprising telecommunication means adapted to exchange surveillance related information with a Command, Communication and Control center. The platform comprises a deck maintained well above sea surface through a connecting member with an underlying, fully or partially submerged, system of floaters and is equipped with a variety of sensors and surveillance systems such as radar, Li-dar, sonar, electromagnetic, unmanned vehicles (UAVs, UUVs and USVs), active and passive self-protection systems as well as research and rescue equipment. A mast having a substantial height (usually 40-50 m) and equipped with appropriate surveillance devices is mounted and ex-tends vertically upwardly the deck.
