50m Ex.Government Research & Survey Vessel

Updated: Feb 12


A well designed and stable hydrographic survey ship that operated mainly in the rough waters of North Sea to survey the Belgium and Dutch coastlines. Always government owned she had an extensive maintenance schedule throughout her life. Offshore Solutions Unlimited took on the design and management for her new role as expedition ship. Just out of dry dock a few weeks ago! Also had her interior refitted with addition of 8 bathrooms. Fuel saving and lower emissions through the addition of a MicFil Nano Filtration System that even eliminates the need for oil changes on all 5 engines!


With her large accommodation she represents good potential for further conversion to a luxury expeditionary cruiser, explorer yacht or dive support vessel. As a government vessel she was never classed under a civil society but we are currently arranging same with little effort as she is very well designed and built for service in the North Sea. She is now under San Marino Flag with all new statutory certificates for a vessel above 500GT and run by an experienced Captain and qualified crew! A rare opportunity to charter a vessel of this calibre with this volume and a very low draft!
