Wave, current and tide monitoring systems help Chinese vessels to safety

Nortek in China advances harbor and navigation safety at Jingtang and Qinhuangdao ports with the installation of real-time Nortek AWAC systems for wave, current and tide monitoring.

For decades, vessel pilots navigating the waters of the Bohai Sea off China’s north-east coast had to depend on their own experience and very limited weather reports in order to decide when and where to bring their vessels into port. This frequently created unsafe conditions for both those on board the vessels as well as those on the coast. For the pilots, it meant a great deal of stress as they did their best to make careful judgments based on limited data.

The benefit of real-time directional wave, current and tide data.

Understanding the need to improve this situation, local authorities in Hebei province have recently partnered with Nortek China to provide real-time directional wave, current and tide data for ports in Qinhuangdao and Jingtanggang. Nortek China provided two real-time
 AWACs, each connected via Nortek’s fully integrated interface system and cables, along with installation and complete support for the data telemetry.

The data from each system is fed to a central station where it is processed and displayed on a designated website and also broadcast to the boat pilots. The pilots now have direct and real-time access to current, wave and tide conditions and no longer need to rely on just their eyes and experience in order to safely dock their vessels.
