Protecting the perimeter at one of Central Europes largest petrochemical facilities.
Polski Koncern Naftowy ORLEN, better known as PKN ORLEN is a Polish company. It is one of Central Europes largest refiners of crude oil. ORLEN specializes in processing crude oil into world-class unleaded petrol, diesel, heating oil, and aviation fuel as well as plastics and other petroleum related products. Employing more than 20,000 people, PKN ORLEN operates 7 refineries, of which 3 are located in Poland: Plock, Trzebinia and Jedlicze. Another 3 are located in the Czech Republic and one in Lithuania. ORLEN processes mainly URAL blend crude oil, shipped from Russia via the Friendship pipeline. Retail network Security at ORLENs main complex in Plock, Poland Securing a surface of more than 800 hectares Thermal imaging: an extra addition to the security network I knew about thermal imaging technology and got in contact with Mr. Swies of Agtes, a FLIR Systems distributor in Poland, who demonstrated me the systems. We practically immediately decided to purchase and install a number of thermal imaging cameras. We opted for FLIR Systems SR-100 thermal imaging cameras. One of the reasons for choosing this type is the excellent range performance. The SR-100 can detect a man-sized target at a distance of no less than 1.6 kilometers away. In total darkness, in practically all weather conditions The FLIR Systems SR-100 thermal imaging cameras are installed along the perimeter and at certain highly restricted areas. The thermal imaging cameras are fixed mounted. They always overlook the same area. In the direct vicinity of the thermal cameras, there is also a CCTV dome installed. If an alarm goes off, and weather conditions permit, we can have a closer look at the situation with the CCTV cameras. Otherwise we send out a walking patrol to check out the situation. Seeing in daylight, through fog, vapor and smoke Thermal imaging and video analytics The FLIR Systems thermal imaging cameras are working perfectly together with our existing video analytics. One of the advantages of thermal imaging cameras is that they are always producing a high-contrast image. Not only during the night. Also in difficult light conditions where CCTV cameras are giving hardly any contrast. This makes thermal imaging perfect to work together with video analytics. Object Video Through a BNC-fiber optic converter, the images produced by the SR-100 are being transferred over fiber optics. At the end of the fiber optics, a fiber optic-BNC converter is installed and the images enter an Object Video Processor. From this processor the images are transferred to the Ethernet so we can look at them whenever and wherever we want. Most of the time we do not even look at the thermal images. Over Digital Signal Processors (DSP) we run Object Video VEW 5.0. Object Video Forensics is installed as an ad-on to this software. Object Video utilizes algorithms to detect objects, and immediately generates useful output such as real-time alerts or triggers for other applications. One of the algorithms we are using is trip wires. If someone or something crosses a certain line, which I can define myself in Object Video, an alarm goes off. Another algorithm is Areas of Interest (AOI). With this algorithm I can define a zone in which no access is allowed. Again, if someone enters the AOI, an alarm will go off. Filters are in place to minimize the number of unwanted alarms. One of the actions when an alarm is generated by Object Video, is that the thermal images are being shown immediately on a screen in the control room. If this happens, the operator decides about the next step that needs to be taken. Thermal imaging, a valuable tool For more information about thermal imaging cameras, please contact: FLIR Commercial Vision Systems B.V. - e-mail : flir[at]flir.com or visit:- www.flir.com | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
