Invented by the Eng. Giancarlo Ravagnan in year ’70, to solve a steel mill problem: separate water from floating oil. A mechanical layout, hydraulic type, with separation by discs was chosen.

A solution which was gradually consolidated over time, introducing increasingly more appropriate systems and machines to resolve the main purpose of separating water from hydrocarbons.

During the years DISCOIL was choosen by Italian Coast Guard and the Italian Navy, as the best oil skimmer to operate in case of oil spills in the sea. In fact it operated with success in many oil spills, such as “Haven” disaster in 1992, “Agip-Abruzzo”, “Moby Prince” in 1991, and to solve the hydrocarbons problem due to the collision between two ships near the Corsica in 2018.

O.C.S. OFFICINE COSTRUZIONI SPECIALI S.p.A. fabricates the oil skimmer DISCOIL, which has been invented in 1970 by the engineer Giancarlo Ravagnan. It has 50 years of experience and offers to its customers personalised solutions.

DISCOIL, patented by OCS, is an oil skimmer, hydraulic type, able to recover hydrocarbons by separation of insoluble floating oil on the surface of water.

The most frequent application is the separation of water from hydrocarbons (petrol, diesel, fuel oils, lubricating oils, crude oil, etc…) and fatty substances in general (animal and vegetable fats, etc…)

The operating principle is based on the adhesion of the oil to the surfaces of stainless steel discs which are arranged perpendicularly and partly immersed in the water, to be treated, while they are kept rotating on their horizontal axis. Molecular cohesion facilitates the recall of oily spots from a distance. As a result of this adhesion and cohesion, Discoil recovers oily products in their natural state at a considerable distance from the machine.

Another important OCS goal is product quality. It is fabricated with resistant materials that guarantee a long lifecycle, and the capability to work in many different and aggressive situations, including classified zones, working continuously 24h/day.

HIGH OIL RECOVERY CAPACITY
It recovers all floating hydrocarbons on the surface of water, creating attraction by discs at distance.

ECONOMICAL RETURN
The oil recovered is for the 98% oil with only 2% of water, so it can be reused in industrial process without any further treatments.

ROBUST MACHINE
It is fabricated with resistant materials that guarantee long-term use, requiring low maintenance.

SAFETY
It can be installed in environments classified as potentially explosive, certified to operate in ATEX Zone 0, 1 and 2.

ENVIRONMENTAL MACHINE
Doesn’t create emulsions recovering oil from water, and working 24h/day doesn’t create sulphur fumes in the air, due to continuous and efficient tank cleaning
