PRODUCT SHEET SUBSEA DATA AND POWER MANAGEMENT Dependable operation of complex underwater sensor and environmental monitoring networks The -4H-Underwater Node routes shore or battery power to the sensors, instruments and equipment in even the largest, most complex underwater monitoring networks, while simultaneously providing secure global access to the system and individually connected elements (dependent on individual capabilities). As a complete system for long-term underwater operation for a variety of subsea monitoring applications that depend on multi-sensor, multi-parameter data, the -4H-Underwater Node is designed to facilitate fast, resilient automated and remote operation. OPERATING PRINCIPLE -4H-Underwater Nodes are seabed residents that act as the interface for networked underwater observatories (RS232/ RS422/ 100BaseT/1000BaseT) ensuring reliable, easy access for operators to collect sensor data and configure parameters according to current requirements. The system also deploys a Smart Safety Concept to automatically secure and protect the subsea network should a failure occur. CUSTOM PROJECTS We support customers to configure Underwater Nodes to their exact requirements including Customer-specific design of measurement setups. Further options, add-on and variables include: ● Back-up battery or primary batteries for non-cable power to smaller sensor networks ConnectorBox for connection of single sensors or complex sensor systems Lander – durable frames for optimised sensor mounting either standalone or integrated to a subsea network T echnology agnostic system with customerspecified sensors and

PRODUCT SHEET -4H-Underwater Node APPLICATIONS The -4H-Underwater node can be used for power delivery, operational control and data management for any subsea monitoring network and is set to be a key enabler for new offshore wind farm developments. Developed under the COSYNA (Coastal Observing System for Northern and Artic Seas) framework, -4H-Underwater Nodes can be installed with a cable connection to shore up to 30 km for year round operation. Through this, it provides the opportunity for continuous observation of processes in the oceans and coastal areas for commercial and scientific users....
