Rolls-Royce: The un-manned ship

Giving a push to the trend of unmanned vehicles Rolls royce is known for it's luxury class of cars, now indulged in producing car engines and turbines has stepped forward for making ship
powered by artificial intelligence not by humans. The team of rolls-royce (blue ocean development team) are working on this project. According to the company the project will be more cheaper,safer and greener results will be there.

The plan has not been started yet but it's a noble thought in the company's mind to work on it.. the 360-degree view of this model is kept in the  Alesund office in Norway.

The concept is unique in its self as it will be a futuristic methodology to have for huge amount of ships.. The human labor will be saved. With just one man handling we can control hundred of ships and the much demanding crews in thousands for these ships will also not be there.. These ships are likely to be there in Baltic Sea within the next decade but are unlikely to reach a global scale due to some hurdles.
These ships will be 12 to 16 percent fuel saving in comparison to loading cargo... Also these ships will be 5-7 percent lighter than the normal ships.
However there are allots of concerns of safety issues.. More is to be spend on the controlling part of these ships and the transmission of signals to it.. It should not matter what is the ship position.. Proper transmission should be there to make it safer and more handy..
Hope these type of things will be soon be seen in this world.. What your ideas about it???
Do you find this concept useful???
