«Petersburg Oil Terminal» — one of the biggest terminal in the Baltic region, Russia, for the oil products transshipment, transportation and storage; the up-to-date specialized transshipment-complex; and the stevedoring company of the Big St. Petersburg Port. The Enterprise (CJSC) was established on June 16, 1995. It’s situated in the south-eastern part of the Gulf of Finland on area of 37 ha. Its capacity is 12.5 million tons of oil products per year.

«Petersburg Oil Terminal» is worked on our equipment from 2006. Based on the digital communicational systems DVS-21 the following functional was implemented:

  • Intercom System;
  • Public Address System;
  • Vandal-proof weatherproof and ex-proof intercom stations with feedback;
  • Explosion Protection Handsets with acoustic-optic signaling devices;
  • Communications Server (NEC PABX) interfacing as with a telephone network so with mobile providers’ subscribers;
  • The Output from telephone terminals and mobile telephones (wireless handsets DECT) to the Public Address network;
  • Automatic and manual fire signaling system.

The first stage of the project was accomplished in 2006. It was consisted of delivery and installation of the digital-exchange unit ProCom DVS-21 and 3 desktop intercom stations, namely: 2 units of DTA-30 (30-keys) and 1 unit of DTA-12 (12-keys).

The desktop intercom stations were installed in the premises of a shiftman, a senior foreman and a railway controller. The task of the scheme was to provide the existing public address network management for the Petersburg Oil Terminal.

During the second stage of the project the 7 intercom stations were in-lined into the system. 5 of them were explosion-proof and 2 of them — weatherproof ones. The explosion-proof intercom stations were located on the terminal’s wharves assigned for the oil-products loading, and the weatherproof ones were located on the territory of boiler-houses № 2 and № 3.

To construct the integrated telecommunication system of the company the digital-exchange unit DVS-21 was interfaced with the digital communication server NEAX 7400 (NEC PABX) due to the relay actuator system (it was done by oil-terminal engineers). The above case was considered to be the exclusion of the rule because for such telecommunication-type the particular card USE2 had been worked out. The present solution allowed to the managing staff of the Petersburg Oil Terminal to control the technological processes and in case of force-majeure to make public addressing via fixed and radio telephones. Also there was implemented the installation of the explosion-proof telephone-sets FHF (EEX Resistel) with optic-acoustic signaling devices.

During the next stage the second digital-exchange unit DVS-21 was installed into the system. It was located in the pumping-house at a 1,5 km distance from the building with the 1st —DVS-21 system. The 2nd —turn digital-exchange unit is linked with the fire-safety system and assigned for the public address provision in case of force-majeure. Both stations (DVS-21) are connected with each other via analog channel with the aid of the specific card 4NSA.

Therefore, there was organized the public address and signaling system which allows to solve the full-range of distance management issues and control the work of the terminal as in day-to-day life so in out-of-control one.
