“An excellent anti-pollution supplement”: this new robot cleans the Santa Lucia port in Saint-Raphaël

A vacuum. One engine, two floats, the idea seems simple and yet it had to be invented. And adapt the pump to perfect depollution, offering cleaner ports to users. Created by a French company, the DPol has just appeared in the new port of Saint-Raphaël. It sucks up the liquid, at a rate of 26,000 liters per hour, swallows the waste and stores it in its nets.

Until now, cleaning the waters of Santa Lucia was carried out by an agent who, at least once a week, collected the rubbish manually. From now on, the employee will be able to concentrate on the maintenance of the mooring and mooring equipment, from the bollards to the organeaux and other mother chains. The DPol will take care of collecting macro-waste.

Easy to move, simple, autonomous… and inexpensive

“We found that cigarette butts, cans, plastic bottles, fenders… any suspended matter was accumulating in certain places. It was therefore appropriate to invest in this brand new high-performance robot, explains Nicolas Marty, municipal councilor from Raphaël, delegate for the sea and the legal coast.

DPol was chosen because it can act on hydrocarbons, which is very interesting. We want Santa Lucia, like the Old Port, to keep their Blue Flag label. This is part of the quality approach of the town’s ports”.

After eight years of effort, seven prototypes, numerous exchanges with ports such as Toulon, DPol was born, simple in design, solid, practical and efficient, easy to move, small and autonomous, easier to handle than a boat… and much cheaper. So much so that the port authority was able to acquire two for Santa Lucia, at the rate of 3,000 euros excluding tax per unit. Purchase which offered regional subsidies due to the positive ecological impact of the device.

Attached to the quay in a corner of the basin, the small machine of only 35kg, developed without electronics or remote control and consuming little, sucks up the waste pushed by the waves and the wind, collecting up to 4kg of waste per minute in its retention bag , a 150 liter filter, easy to clean as soon as it is full. Several nets are thus available, made with more or less fine meshes depending on the type of fines targeted.

The system sucks up the hydrocarbons

Several robots can be connected to form a sort of floating barrier, thus multiplying the area cleaned.

A good way for the marina, which is committed to the preservation of aquatic environments and the development of coastal and marine activities, to retain its European certification of “Clean Port”.

“For example, if a boat sinks, the DPol is placed, which is largely surrounded by a barrier of retention tubes attached to its floats. The engine sucks up the oils, the petroleum which it rejects behind it, in the perimeter where place oil-absorbing blotters. It is an excellent anti-pollution supplement”, explains Mathieu Bertora, director of the Saint-Raphaël ports authority.

An innovation from the Roquefort-La Bédoule shipyard in the Bouches-du-Rhône which will help preserve the bay of the seaside resort.
