Fifty years ago, on 10 July 1976, the explosion of reactor A101 at the ICMESA plant in Meda (Milan) released 2,3,7,8-TCDD, known as “Seveso dioxin”, into the environment. It was the world’s most severe case of contamination by this substance and marked a definitive turning point in the global perception of environmental risk, contributing to the first European Directives on

SEA Marconi has just completed a dehalogenation treatment (performed on-load, with the transformer energised and under load) at a hydroelectric power plant in Romania. These activities are routine for SEA Marconi, which performs 20 to 25 transformer treatments simultaneously every day in different areas of the world. In this specific case, however, the intervention was successfully carried out despite particularly

  On May 27, 2025, the CEI – Italian Electrotechnical Committee hosted in Milan a technical seminar titled: “Dielectric liquids for transformers: from mineral oil, through PCB, to esters”. Sea Marconi took part as a sponsor and speaker, offering a perspective that bridges the past and future of asset and risk management for transformers. The first presentation, by Vander Tumiatti,

We are particularly proud to be able to recount another positive update in the “PCBs free Program for Japan” project: the arrival of the first order for the development of a system (DMU) for the dehalogenation of oils and transformers contaminated by PCBs. To completely understand the extraordinary nature of this news, we need to take a look at theRead more

The treatment was performerd on-siteRead more

During the last week in November, Sea Marconi received a delegation coming from the Philippines. The Sea Marconi’s experts have visited the Republic of the Philippines several times (we have already reported in April 2011 the official invitation to Vander Tumiatti as expert in the management and decontamination of electrical equipment with insulating fluids) and thanks to the competency provided, the projectRead more

A few days ago the fabrication of a plant for Mongolia, finalised toward the dehalogenation of electrical equipment with insulating liquids contaminated by PCBs was completed. This plant is of a DMU (Decontamination Mobile Unit) type with extremely innovative configuration and technical solutions. It is a plant made of two modules designed and developed in a manner allowing the operators to work insideRead more

The topic of decontamination from PCBs is very much felt by the French Ministry of the Environment. In effect, last December, the minister Kosciusko-Morizet reminded that in all Europe, Directive EC no. 96/59 imposed to decontaminate or dispose of within 31stDecember 2010 all the equipment with PCBs exceeding 500 ppm (mg/kg). After this communication, an investigative campaign followed to verifyRead more

In the issue of the ERDF publication “PCB Actu” dated 7th February, the “Distribution “ division of the French energy colossus, reviews the situation of the decontamination program from PCBs of its electrical transformers. We point out that this activity is performed by Sea Marconi with reference to a multi-year contract signed (and then renewed) with the French company in 2005. Thus,Read more
