Dewar Electronics have announced that Lantech Maritime series of industrial Ethernet switches consists of control room switches and device-end switches, all which have passed comprehensive DNV test criteria.
Marine network applications, one is On-shore and the other is Off-shore. On-shore applications include lighthouse surveillance, wind power controlling and monitoring systems, and tide power controlling and monitoring systems. Off-shore includes IP networking for oil platforms, battleships, yachts and cruise liners.
The challenges of marine network applications include coping with harsh environmental conditions. These conditions include extreme operating temperatures, heavy moisture, erosion, extensive shock and vibration. Also, extensive EMI can prevent some equipment used in the ship, especially compass and navigation systems, from operating properly.
Problems caused by erosion, heavy moisture and extreme working temperatures are common in marine applications. Lantech Marine series industrial Ethernet switches are designed to cope with these problems. Given the diversity of locations that the switches may be used, industrial Ethernet switches are needed for the various types of approvals under DNV classification.
DNV (Det Norske Veritas) maritime certification specifies the test criteria for all equipment used in ships, high speed and light water craft as well as Off-shore oil platforms. The DNV organisation originated in Norway. Initially, DNV was to provide consulting services for managing the risk and quality control systems on-board ships. DNV Maritime is recognised by 80 national maritime authorities in managing their risk for ‘Tough’ maritime environmental conditions.
DNV uses test categories to verify products for satisfactory operation in typical on-board environments. These tests among others include temperature, humidity, vibration, EMC and compass safe distance.
