Perforated and Closed-Bottom Cable Trays

Cable trays are used in the industrial plants to protect the laid cables. Specifically, the PS and AR perforated series are characterized by more lightness and by a good ventilation of the cable inside. The typology FC (closed bottom) is particularly suitable for environments where the cable isolation is essential.

Thermal expansion: Our joints with crossed slots allow an even greater deviation between the elements, recovering any possible expansion without damages.

Electrical continuity: The electrical continuity of the cable trays is guaranteed by the correct assembly of joints and/or the copper bonding jumper; for this purpose, properly marked grounding holes are made on the cable trays and cable tray accessories.

Berri Oil Field Expansion

The Berri field, situated along the eastern coast of Saudi Arabia, is undergoing expansion through the Berri Increment Program (BIP) to increase its crude production capacity to 500,000 barrels per day (bpd). Initially discovered in 1964, the Berri field commenced crude oil production in 1970, with the Berri gas plant starting operations in 1977. Currently capable of producing 250,000 bpd of Arab Light crude, the field’s expansion program aims to double its crude production capacity through enhanced oil recovery techniques.

New Hydrogen Production Unit – Porto Marghera

The project aims at implementing two hydrogen production lines for the Venice biorefinery in Porto Marghera. Its primary objective is to increase the availability of hydrogen at the biorefinery to fulfill the requirements of the EcofiningTM unit in terms of quality, quantity, and availability, all while optimizing energy efficiency. As part of a phased transition to producing decarbonized hydrogen, these units are designed to significantly reduce the emission of fossil CO2 into the atmosphere by utilizing biogenic charges recirculated by the EcofiningTM unit.
