OASI

This system can recover the loss of hydrocarbon in the sea. It has been created to be a quick solution against the oil leaking situations. Oasi is extremely ductile because it can be successfully applied in all the oil leaking situations: it can be used with all the weather-atmospheric conditions, it recover all the hydrocarbon mixtures, from the liquid ones to the dense ones.

Oasi is a whole new concept, different from the others hydrocarbon recovery systems due to its flexibility to act in all the weather-marine situations and to collect in the first time the whole oil slick, without struggling with different densities problems.

This is an easy and intuitive system, not hard to assemble, who can speed up, simplify and coordinate the acting operations. The design process makes the whole building process easier because a strength point of the product is the interchangeability of its parts and it can be used in all the different threats we need to face.

In case of a disaster with an extended oil leak, in order to elevate the speed of the recovery operations, the OASI system is also suitable with more recovery placement.

How does it works?

By arriving in the site, the operators relase a particular floating, articulated and modular device, able to face the sea stresses. It is covered by an innovative material, able to absorb the oil waste from the water (in 6 seconds, it can absorb 12 times his weight in oil waste).

Then, one of the two ends of the device is locked in the recovery system while the other run inside a motorizzed pulley system. Those pulleys allows the recover of the floating device and the movement created by them is able to grab the hydrocarbons and put them inside the recovery placement where they may be collected in safety. 

By recovering the float, the generated tide walks the oil throught the station. Here, the Hydrocarbons are pushed into a jetties system that, once crossed, it block the oil inside the central nucleus.   

Design and science against oil spill pollution

A new tipe of material can absorb oil from water

In this study, we present a novel composite material based on commercially available polyurethane foams functionalized with colloidal superparamagnetic iron oxide nanoparticles and submicrometer polytetrafluoroethylene particles, which can efficiently separate oil from water. Untreated foam surfaces are inherently hydrophobic and oleophobic, but they can be rendered water-repellent and oil-absorbing by a solvent-free, electrostatic polytetrafluoroethylene particle deposition technique. It was found that combined functionalization of the polytetrafluoroethylene- treated foam surfaces with colloidal iron oxide nanoparticles significantly increases the speed of oil absorption. Detailed microscopic and wettability studies reveal that the combined effects of the surface morphology and of the chemistry of the functionalized foams greatly affect the oil-absorption dynamics. In particular, nanoparticle capping molecules are found to play a major role in this mechanism. In addition to the water-repellent and oilabsorbing capabilities, the functionalized foams exhibit also magnetic responsivity. Finally, due to their light weight, they float easily on water. Hence, by simply moving them around oilpolluted waters using a magnet, they can absorb the floating oil from the polluted regions, thereby purifying the water underneath. This low-cost process can easily be scaled up to clean large-area oil spills in water.

Storyboard

*All recovery times change according to the amount of oil dispersed.
8 AM - A ship releases a large amount of oil into the sea.
12 PM - The collecting station is deployed and a Coast Guard boat start to releases the float covered with absorbent material all arround the oil stain.
One of the two ends of the floating device is locked in the collecting station while the other floating device end run inside a motorizzed pulley system.
2 PM - All the oil stain is circumscribed by the floating device so the oil it can't be able to scatter itself.
The motorized pulley system allows the recover of the floating device and the thrust created by them is able to grab the hydrocarbons and put them inside the recovery placement where they may be collected in safety. 
8 PM - All the oil stain has been recovered inside the floating collecting station.
11 PM - The Coast Guard boats recover the hydrocarbons in safety
02 AM - The Coast Guard boats carry the hydrocarbons ashore where they will be destroyed.
