Sim One: A Revolutionary Tsunami Monitoring Device

He Li, Nankai Cheng and Li Yang's Innovative Approach to Tsunami Detection

The Sim One device is a response to the urgent need for more accurate tsunami detection methods. Current warning systems, based on earthquake data simulations, have proven to be lagging and inaccurate. Sim One's design allows for real-time monitoring of the ocean's internal dynamics, providing a more accurate and timely warning system. This innovative approach has the potential to save tens of thousands of lives.

Sim One's design is not only innovative but also practical. The device is anchored in the open sea by an offshore work vessel and fixed by special ropes. Its buoyancy is provided by an empty compartment inside the device, allowing it to be suspended at a fixed depth. The structural shell is primarily made of aluminum bronze and titanium, with an inorganic seawater anti-corrosion coating on the surface.

The device's unique properties extend to its operation. Several devices are anchored in the ocean along a chain distribution, each separated by 30-50 kilometers. This forms a monitoring network for the ocean's internal movement. When a device detects dangerous ocean currents, it releases a communication buoy that floats to the sea surface to send out early warning signals and data. If several adjacent devices emit tsunami signals almost simultaneously, an alert is issued to coastal areas.

The Sim One project began in February 2020 in China and was completed on January 27th, 2023, in Lisbon. The project's research provides a guiding significance and a theoretical basis for the new design, mapping tsunami propagation properties and discovering critical points for tsunami monitoring. This research has led to the design of an accurate and reliable tsunami early warning system, which can reduce the threat of marine disasters to coastal residents and provide comprehensive ocean state data.

The Sim One device has overcome several challenges, including wave spectrum monitoring, anchoring in deep waters, monitoring data modeling and analysis, and ensuring reliable and long-time functioning. Despite these challenges, the design team has finalized a feasible and applicable solution. This innovative design has earned the Golden A' Product Engineering and Technical Design Award in 2023, a testament to its outstanding and trendsetting creation.
