The Brazilian Navy Hydrographic Center and Petrobras launch the first national meteo-oceanographic buoy noticias

The Naval Hydrography Center and Petrobras provided the first buoys on October 21st, which were launched in the so-called Pre-Sal region in order to set up a data acquisition network and validate operations. As one of the deepest meteo-oceanographic buoy moorings ever made in South America, with a depth of more than two thousand meters, incorporating several technological advances in the special mooring line and using a new data collection method with three coupled cameras that validates new wave data acquisition system and introduction new collection buoys of reduced size (observation buoys).

Meteorological and oceanographic information is important for marine operations and in all phases of a business in the offshore oil industry. In 2019, the Marine Hydrographic Center and Petrobras signed the Oceanographic Modeling Observation Network (REMO) collaboration period to set up a network for the collection of oceanographic meteorological data and develop a buoy using Brazilian technology: the National Oceanographic Meteo Buoy. (BMO-BR).

The companies involved in the development of the BMO-BR are MessenOcean and Holos. The launch into the sea is carried out in the first fortnight of November by the hydro-oceanographic research vessel Vital de Oliveira, which belongs to the group of hydro-oceanographic vessels. This joint effort of the various military organizations under the coordination of the Directorate for Hydrography and Shipping will lead to a reduction in costs and a higher availability of meteorological oceanographic information for the Navy and will also contribute to the development of the national industry.

BMO consists of a single platform on which environmental sensors are installed in order to record, among other things, meteorological data, gravitational waves, currents and physico-chemical parameters of seawater according to customer requirements. The collected data can be transmitted to a virtual server via satellite, radio or GSM and then made available for viewing and downloading on a web portal. In this way, the BMO offers a complete data acquisition system for meteorological and oceanographic monitoring in real time. It is an autonomous platform powered by solar panels to collect directional measurement data from waves, winds and currents in the ocean.

Each BMO has an inertial motion sensor and a complex system for measuring the direction of waves, currents and winds, essential data for the safety of navigation and offshore projects. (Javier Bonilla)
