ADASA installed three maritime stations in Togo to protect and monitor its Gulf of Guinea coastline


  • Installed three new coastal marine stations and two current meters for continuous measurement of meteorological variables and sea waves.
  • Provided a web service giving real-time meteorological and maritime data to the fishing and merchant port of Lomé.

Lomé’s Maritime Office wanted to strengthen the environmental monitoring capabilities along its Gulf of Guinea coastline. ADASA was entrusted to install and operate three coastal maritime stations, the first of their kind in Togo’s waters. The stations now help the Togolese maritime administration ensure sea safety, prevent pollution episodes, and safeguard the marine environment. They also protect marine and underwater infrastructures along Togo’s coast.

The three stations, equipped with meteorological sensors, were distributed along a 65-kilometre stretch of coastline in the Gulf of Guinea. In addition, two of the stations — located one kilometre offshore and at a depth of 15 metres — have meters that monitor seawater flows and waves. These current meters continuously measure and transmit data on water temperature, pressure, and current speed and direction at every metre depth. The meters also send representative wave information such as the direction, frequency, and the maximum and significant wave height.

Each current meter’s was integrated with the data logger using the NMEA standard communication protocol, commonly used in marine instrumentation and GPS receivers.

Stations transmit data to a cloud using M2M SIM cards, giving Lomé’s Maritime Office real-time access to data that they can now share among managers from any location. This connectivity facilitates decision-making about the operation of Lomé port’s fishing and merchant activities, including mooring petrochemical vessels on the Kpémé platform, Lomé’s commercial phosphate port.

This project consolidated ADASA’s position as the prime hydrometeorological solutions provider in Africa, where we cover everything from environmental control to the protection of maritime infrastructures against adverse phenomena.
