Thanks to the high qualification of our specialists, LVR Fleet provides hydrographic services in accordance with the international standards and quality requirements.
We use 2 specially equipped hydrographic vessels LĪNE and LĪVA for seabed survey. In 2022, an unmanned surface vehicle – OTTER was added to our fleet, which is the first drone of its kind in the Baltic States. OTTER increases the mobility of the LVR Fleet in providing hydrographic services not only in the port, but also in other water bodies. With OTTER, we have already made surveys in the Riga Freeport, lake Dridzis, Riga City canal, Ogre HPP, Freeport of Ventspils, Plavinas HPP, Liepaja SEZ, Lielupe river in Jurmala and Jelgava.
