CCTV Solution Kit for Hazardous Areas on Offshore Platforms

Mar 29 2010

R. Stahl (Germany) has compiled a scaleable package comprising cameras and a recording system for camera surveillance in hazardous areas on gas and oil rigs. In addition to making operations safer, it enables users to carry out a thorough study of causes and fix any problems in the case of incidents, since the system supports both live monitoring at HMI stations as well as complete documentation of events.

The standard package includes four cameras whose video signals can be recorded manipulation-proof for up to ten days. This net-work-compliant solution also permits authorised remote access to images via the internet. If users wish to integrate more image sources, the system can be easily expanded to include twice or four times as many cameras. While the standard package features a 500 GB hard disk, the recording capacity can also be easily expanded to meet specific application requirements. Resolutions of up to 4CIF, i.e. full PAL format with 704 x 576 pixels, can be selected for the H.264 compressed digital video files. A PTZ control module is available for the remote control of the pan/tilt/zoom functions of the cameras.

The standard set includes four type EC-710 spherical cameras for zones 1 and 2 designed to endure even very rough conditions on offshore platforms in ex-treme climates. Their steel housing can withstand aggressive chemical substances and protects the cameras from substantial mechanical stress. It can be installed in ambient temperatures ranging from -30°C to +75°C. A heater is used to prevent condensation or frost forming on the surface. With a diameter of only 55 mm and a mere 435 grams, the cameras can be fitted into the smallest of spaces.

The fixed viewing angle of the hardened lens is +/- 90° horizontally and 68° vertically. In addition to the EC-710 and other camera models, video server and recording technology, various HMI station types for local surveillance, and suitable software solutions, R. Stahl can also provide any peripherals as part of the system solution. A broad range of cables, switches, explosion-proof terminal boxes as well as additional input devices such as keyboards or joysticks for remotely controllable camera models are available.
