The article reports that a German company is producing sails that may help propel ships across the sea faster and cheaper than modern engines. The system is called SkySails, and it consists of a towing kite and navigation sof...
mounted on one side: this dampens the wave motion.16) • One attraction of floating technologies is the possibility of putting the turbine on the substructure in port and towing the complete unit to its moorings in one piece, reducing the amount of construction work to be done at sea. Ho...

In addition, ship speed and power performance under the respective wind profiles can be complemented with model tests and sea trial results. In general, ship model tests and sea trials are conducted under calm water conditions, where the required ship power/thrust levels for a selected range of...
With a weight of 4,900 metric tons and a longer tower barrel than an ordinary wind power project, it caused great challenges in transportation and handling and brought difficulties to offshore towing and navigation safety assurance work.
accurate predictions of vessel performance which will be compared to the demonstration vessel Pacific Grebe as part of the project. This will require innovative numerical simulations backed up by experiments conducted in our highly instrumented 138metre Boldrewood towing tank and RJ Mitchell wind tun...
The primary market for SKYTUG is bulk carriers and tankers of Handymax scale and above. Ro-Ro vessels can also benefit greatly from wind propulsion, and container ships could make significant savings by hiring SKYTUG towing services; in fact, SKYTUG is the only known solution that can provide...
