UTILNAVOREP S.A. made all these signaling systems in accordance with international shipping regulations.
After commissioning, UTILNAVOREP S.A. ensures and provides maintenance for all of these systems.


a) Starting from year 2004 S.C. UTILNAVOREP S.A. established in collaboration with CN APMC (National Administrative Company of Maritimal Ports Constanta) the department of Aids To Navigation - Maintenance of signaling systems for the Black Sea ports.
– Taking over through a public auction the ensurance of maintenance of signaling system for the ports Constanța, Midia and Mangalia, UTILNAVOREP specialists learned step by step the functioning and maintenance of this system of a major importance for safe navigation.
– The rapid accumulation of knowledge in this field was facilitated with the collaboration of french company GISMAN one of the biggest manufacturers of this kind of systems.

The fact that we have managed, in a short time, to specialize in signaling systems is proven by the successful realization of two large-scale works for CN Administration of the Navigable Canals Constanța, works described in the chapter "Civil and industrial construction", respectiv : – Sistem of Navigation and Signalization on the Denubian-Black Sea Channel and
– Navigation sistem and signalization on the Channel Canalul Poarta Albă – Midia Năvodari

b) MAINTENANCE of systems and industrial equipment is rather a new activity for UTILNAVOREP but wich we intend to amplify. The beginning was started when UTILNAVOREP adjudicated the auction for the ensurance maintenance of the grapple crane from Section Flexicoking of PETROMIDIA Refinery.
– The contract was awarded also in the coming years, with very good results. This led to the expansion of cooperation with this company to provide maintenance for lifting equipment on the Petromidia Platform, and also for loading installations of petroleum products from the Petromidia Platform berths.
