Ev Nautilus

ev-nautilus-2015Maritime Management took on this exciting project in early 2009 when we were engaged by Ocean Exploration Trust (OET) to reactivate this experienced but tired East German research vessel. The ship has been dramatically upgraded, and modernized since then under our overall technical and project management and was achieved without interrupting the vessels operational season each year.

This was the start of a long and successful co-operation with OET under the leadership of renowned undersea explorer Dr. Robert Ballard.  Dr. Ballard is known for the discoveries of the Titanic, PT 109 and the Bismarck and being an inspiration to young and old to unlock the secrets on the ocean. The ship is equipped with state of the art ROVs operating at down to 4,000m and vast array of sensors and sonar equipment including  Kongsberg EM302 Multi Beam Echo Sounder MBES. The vessel is set up and ready service OET requirements for exploration of the Geology, Biology and Archaeology of the depths and through live broadcasting and outreach programmes, to bring the excitement to educators and students ashore.
