The E/V Nautilus is perhaps the most famous exploration vessel in the world.

Maritime Management took over the management of the vessel in 2008 and have since operated and updated its capabilities through numerous modernisation projects over the years.

Our Client Ocean Exploration  Trust (OET) is a not- for- profit organisation, founded in 2008 by Dr. Robert Ballard to engage in pure ocean exploration.

OET’s international programs centre on underwater scientific and educational exploration.

Expeditions commenced in the Mediterranean and Black Sea in 2009 and extended to the west Mediterranean and Eastern Atlantic while operating from a base in Turkey.

In 2013 NAUTILUS crossed the Atlantic to commence operations in the Mexican Gulf and Caribbean until 2015.

2015 saw the vessel transit to the Pacific via Panama Canal to embark on series of groundbreaking expeditions on the USA west coast, Canada and Mexico, venturing as far afield as Hawaii and Samoa.

NAUTILUS is now a state of the art exploration vessel with sophisticated Satellite communications to broadcast live video feeds from ROV cameras to a depth of 6000m.

The vessel is also equipped with high performance Multibeam echo sounding, ADCP, USBL, Sub Bottom Profiler, Dry and wet labs, DP capability, moonpool, ROV command centre, 4m hull extension, New fuel efficient main engine, generators and ship systems.

The multiple upgrade work on all of the vessel systems which have been carried out under the watchful supervision of the Maritime Management team are detailed in the PROJECT links on the website.

NAUTILUS is a multi functional vessel providing the ability for our client to provide expedition programmes including detailed High Res mapping, marine biology, geology, oceanology, volcanology, marine archeology, 4k video formROV’s, platform for launch and control of AUV’s, ASV’s and experimental vehicles.

During the COVID 19 pandemic, a lot of Nautilus’ busy calendar was halted. We at Maritime Management are taking things a step further to ensure continued success in the ships future. Nautilus is getting a near complete mechanical upgrade. Beginning in 2018/19 off season, the Nautilus has been refitted with a new traction winch allowing scientists and marine biologists to reach depths of 6000 metres in ROV exploration. In the current off season 2019/20, despite the ongoing challenges of the COVID-19 pandemic, our management and excellent crew on board successfully continued to undertake the long planned re-engining of the Nautilus. The new ABC 8DZ four stroke engine installed is a modern, fuel efficient, lower emissions propulsion system that perfects Nautilus’ ocean surface manoeuvrability, as well as a cleaner more environmentally friendly way of exploring our oceans. It will give greater utility for mapping and station keeping that is crucial to oceanographic research where accuracy is paramount.  See below some images of the project so far. More updates to follow in our news section.
