Following its construction in the Netherlands by U-Boat Worx, this Cruise Sub 7 underwent harbour and sea trials before being delivered to a client in Asia.
Since delivery, it has never been used, meaning the submersible is virtually brand new.
She has been stored in a suitable environment, ready to embark on an adventure.
Due to its period of inactivity since original delivery, the submersible needs to be serviced by the manufacturer.
It also needs to complete its 300-meter sea trials.
The original manufacturer is ready to provide these services, which will also be overseen by its classification society — DNV — to ensure compliance with applicable standards.
Don’t hesitate to contact SUB71 for more detailed information about timelines.
