Telescopic Buoy

Portfolio Description

Conventional navigation buoys share a critical flaw: their fixed height leaves them vulnerable to submersion when water levels rise, compromising visibility precisely when maritime safety matters most. Tasked with reimagining this essential infrastructure, KEVOS® developed a telescopic buoy concept that adapts seamlessly to fluctuating water conditions—delivering reliable visibility without dependence on motors, sensors, or electronic systems.

Our design response centred on a buoyancy-driven telescoping mechanism, engineered through concentric sliding sections that extend and retract in direct response to water elevation. As levels rise, internal buoyant force activates each successive segment, preserving a consistent beacon height above the waterline at all times. The system is entirely passive—mechanically elegant, energy-independent, and built for long-service environments.

Complementing the core mechanism, the concept integrates stabilising fins for performance in choppy conditions, marine-grade composite materials for corrosion resistance, and a high-visibility reflective head for round-the-clock navigation safety. The result is a sleek, cylindrical profile that performs reliably across rivers, ports, flood-prone zones, marine construction sites, and tidal coastal waters.

While the project remained at proof-of-concept stage due to stakeholder budget realignment, it successfully validated a forward-thinking solution to a persistent maritime challenge—and reinforced our methodology for designing under variable environmental conditions while balancing innovation against real-world commercial constraints.
