Great Dionaea V1

Spilled oil collecting device whereby pollution prevention is possible using non-pollution prevention boats in linkage with oil collection fence. As a non-powered type without additional energy consumption, oil and water can be Quick and effective response to oil spill accidents (high efficiency, wide area and automation)
All-in-one attachment/detachment system : spilled oil gathering-collection-storage

• Usable by installing in costal fishing boats, not existing disaster prevention ships.
• Spilled oil gathering, collection, and storage become easy with dismountable all-in-one system.
• Automatic spilled oil collecting device for large area can quickly and effiectively respond to spilled oil accidents.

Inspired by Nature. Driven to Protect it.

Field sampling is essential to monitor the impact of our cleanup, and it helps shape our strategy.
Observational and applied studies are at the heart of our research on oil leak pollution. Systematic and
accurate field data enable us to better comprehend the nature and evolution of ocean sustainability.

To refine our knowledge of sources and transport of ocean oil leak, we conduct experimental tests that monitor how different oil is displaced. We look at the actions of wind, rain, and gravity – both on land, as well as in oceanic currents, waves, and wind at sea.
What we learn is applied to our analysis, giving us greater confidence when predicting the fate of ocean oil leak pollution and the long-term evolution of ocean oil leak patches if left untouched.
