Harbour Management

HF ocean radar data can enhance the information for vessel traffic management. Dangerous currents in shipping channels can be identified and even short term forecasts can be provided to improve the safety of navigation in particular at harbour entrances.

These shore based radar systems offer highest reliability and very high data availability in all weather conditions. With the drift prediction software, the WERA data can be used to forecast critical ocean currents or waves at particular locations and automatically generate an alert. In case of oil spills or lost containers, it can be an important tool for environmental protection.
