Jospa Tug

As it is wave-powered, costly fuel and emissions do not arise: as it is unmanned (remote-guided), the costs of a crew are also saved. At some time soon “autonomous” – unmanned, remote- controlled via e.g. satellite, -operation, as is also now being planned for autonomous cars, will be permitted. The “Jospa Tug” concept has been proven (and advanced to “TRL4” in technical terms), protected by European and US patents. The tug potentially competes in all ocean-shipping modes. Initially it must prove itself in applications where its slow speed is desirable.
