Keuning, J.A. (author)The invention concerns a vessel (l) comprising a transfer system for transferring persons or goods from the vessel while subjected to waves and/or swell towards a substantially stationary destination, wherein the transfer system comprises a platform (2) having a first mass for supporting the persons or goods during transfer, and platform...patent 2014

Keuning, J.A. (author)The invention concerns a ship whereby the hull and the mechanical propulsion device are designed such that the Froude number is larger than 0.5. In the aft ship the hull has a bottom with V-shaped bottom surfaces with a deadrise angle that is less than 40 degrees and the hull has substantially vertical sides. In the hull are a passenger...patent 2014

van der Kolk, N.J. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author)Wind energy as an auxiliary form of propulsion for commercial ships has again become of great interest as a possible response to volatile fuel prices and increasingly stringent environmental regulations. A well-founded performance prediction tool is a key prerequisite for the further development of this promising technology, and with the support...conference paper 2016

Bordogna, G. (author), Keuning, J.A. (author), Huijsmans, R.H.M. (author), Fossati, Fabio Vittorio (author), Belloli, Marco (author)In recent years wind-assisted propulsion for commercial ships has gained an increasing interest as valuable alternative to reduce fuel pollutant emissions. However, the development of feasible and commercially viable wind propulsion systems to partially (or fully) propel a ship is nowadays hindered by the difficulties of modelling the...conference paper 2016
