In Hamburg presented drone to deliver goods by sea: a robotic barge with electric motor
Corporation Amazon, probably was the first company to introduce a viable project delivery of goods over short distances through the air, using drones quadrocopter. However, lawmakers banned the use quadrocopter to deliver goods within the city, but Amazon does not give up and continue to work on the project.
Besides, now underway, and similar work on creating an automated system of delivery of cargoes by sea. Engaged in this project research company DNV GL, which presented the first results of the work on marine technology exhibition in Hamburg.
Development DNV GL - automatic barge without a team, with the electric motor. This barge can transport TEU-100 standard containers at a relatively small distance at a speed of 6 knots. Since there is no command barge, it does not need any safety equipment or cabins, nor any other infrastructure, which is typical for a ship with a crew of sailors.
Servicing barges need much less money than usual maintenance of the ship. Consequently, under similar terms and volumes of cargo delivery, marine drone will cost the company owning the ship is much cheaper with the team. Operating expenses, including salaries, various insurances, food, rescue equipment - reduced several times. According to the developers of the project (by the way, his name ReVolt), robotic barge shipowner cost a million dollars a year cheaper than a similar capacity (or if you use the nautical term - displacement) and other parameters of a diesel vehicle.
ReVolt causes minimum damage to the environment, due to the lack of a diesel engine and all of the same team.
