Replacement of 2 existing PLCs (for tank loading and fire-extinguishing) with a modern and comprehensive automation solution.
SOLUTION
RESULT
We completed the upgrade in less than 36 hours.
AS Hellas has been cooperating with ELPE since 2011, and when they wanted to replace two old PLCs for the tank loading and fire-extinguishing operation at Ionia Thessaloniki, they called upon us. The migration to the new system was completed in less than 36 hours, as it had been thoroughly prepared at the premises of AS Hellas. We essentially avoided any downtime in the ELPE facilities.

The existing system had considerable difficulties finding spare parts and keeping up with maintenance, while the lack of scalability and the outdated technology made it imperative to replace. They requested the replacement of the SYLVANI system with a modern andunified automation solution.
HELLENIC PETROLEUM (ELPE) is one of the most important energy groups in Southeastern Europe.
From 1962 until today, the Group’s contribution to the economy of Thessaloniki region, in particular, is significant. Over the past five years alone, the group invested more than 400 million euros in the area. It is estimated that ELPE provides about 1.7% of the city’s GDP and ensure its energy supply.
SIEMENS’ new integrated automation system consists of a PLC in redundancy mode and incorporates the two functions (Fire Extinguishment, Operation). Both imaging and remote control are performed from two touchscreens. The use of fail-safe (hardware, software) equipment covers the specifications of the project.
The system consists of the following elements:
On-site work on the migration from the old to the new system included the following:

Before
After
The new hardware significantly improved the reliability of the system, operation, and handling, and at the same time reduced maintenance costs due to direct support and spare parts availability.
Also, the installation can support new features and can easily interface the system with other data capture and processing systems.
Finally, programming will no longer be a problem since this system is the most popular in the market and there are a lot of developers to work with.
