At the Abbiategrasso sluice gates, lowered gates had let weathered hydrocarbons build up, an iridescent sheen ran along the canal, and bituminous residues heavily contaminated the slipway and the north bank. The response had to contain the weathered oil, intercept the incoming sheen and protect the waterway downstream.
The first absorbent line (1) crosses the canal and holds back the dark oil film and floating vegetation (2). The second line can be seen further downstream.

The absorbents handled the sheen. Targeted manual and mechanical removal took out the solidified fraction of the hydrocarbons.
FoamFlex SorbTube (TB50), FoamFlex Carpet 2.0 (CRP20) and SLS20 were laid as two lines across the canal to intercept the incoming sheen and limit the build-up of oil at the sluice gates.
Targeted manual and mechanical removal took out the solidified fraction of the hydrocarbons alongside the absorbent lines.
The canal reach downstream stayed protected while the upstream sections were stabilized, so the slipway and bank were ready for final remediation.
The surface hydrocarbons accumulated at the sluice gates visibly decreased within the same day. The FoamFlex lines intercepted the incoming iridescent sheen.
The Naviglio reach downstream was not compromised during the work.
Absorbents handled the sheen and mechanical removal handled the solids, so containment started immediately and cleanup proceeded in stages. The contaminated slipway and bank were left ready for final remediation.
FoamFlex SorbTube (TB50), FoamFlex Carpet 2.0 (CRP20) and SLS20.
High-capacity absorbent sock for oil containment in industrial or marine areas, available in three different sizes.
Reusable absorbent carpet with velcro and handles, ideal for all types of spills and compatible with FF-WRING.
Two FoamFlex absorbent lines laid across the canal at Abbiategrasso intercepted the incoming sheen and limited oil build-up at the sluice gates. Lines placed across the flow catch the sheen as the water carries it onto them.
No. At Abbiategrasso the absorbent lines handled the sheen, and targeted manual and mechanical work removed the solidified fraction. Using both gave immediate containment and gradual cleanup.
Yes. At Abbiategrasso, keeping absorbent lines in place while the upstream sections were stabilized protected the downstream reach. It also prepared the final remediation of the slipway and bank.
