(author)The purpose of this paper is to highlight the stages where standardization is needed for model-based simulation as part of the holistic design and operational performance assessment of ship machinery systems. This need may rise in different stages of ship lifecycle, when model results are used and compared (e.g. as performance metrics for bids)...conference paper 2019

Bastiaansen, H.J.M. (author), Lazovik, E. (author), den Breejen, E. (author), Broek, J. (author)Maritime autonomous and unmanned shipping have considerable potential for cost-effective and safe cargo or passenger transport and other maritime operations. Such a manner of shipping will introduce operations chains with new roles and responsibilities. Widescale adoption requires an agreed upon overarching business process framework and...conference paper 2019

(author), Schutte, K. (author), Dijk, J. (author)Detecting maritime targets with electro-optical sensors is an active area of research. One current trend is to automate target detection through image processing or computer vision. Automation of target detection will decrease the number of people required for lower-level tasks, which frees capacity for higher-level tasks. A second trend is that...conference paper 2018

Janssen, J.A.A.J. (author), Hasenpflug, H. (author), Janssen, M. (author)Crews of naval vessels lack an up-to-date awareness of those aspects of a ship’s susceptibility to threats that are related to the actual ship signatures (acoustic, magnetic, infrared, etc.). The ship’s susceptibility depends among others on the current configuration of the ship, the environment, the enemy sensor capabilities and the related...conference paper 2018

Dijkers, H.P.A. (author), Hooijmeijer, P.A. (author)Ammunition transshipments are a key part of the logistical operations of the armed forces and are often executed via ships. These transshipments pose a risk to the people present in the area surrounding the harbor, where the loading/unloading of the ship takes place. A method is presented to perform a quantitative risk assessment of such...conference paper 2018

van Kempen, E.C. (author), Vredeveldt, A.W. (author), Hoogeland, M.G. (author)A three degree of freedom external dynamics calculation model for ship grounding has been made, which is used to predict the extent of bottom raking damage and the grounding force with associated decelerations of the ship in terms of surge, sway and yaw. When the ship decelerates, caused by a grounding event, these motions can be logged through...conference paper 2018

Jansen, H.W. (author), de Jong, C.A.F. (author)Thecontributionofshippingnoisetothebackground noise in the seas can be estimated by shipping noise maps. Noise maps can be made by applying appropriate modeling tools for underwater sound propagation and ship source levels to information on the acoustic environment and on the ship traffic in the area of the map. The development of reliable source...article 2017

Nieuwenhuizen, R.P.J. (author), Kruithof, M. (author), Schutte, K. (author)High resolution imagery is of crucial importance for the performance on visual recognition tasks. Super-resolution (SR) reconstruction algorithms aim to enhance the image resolution beyond the capability of the image sensor being used. Traditional SR algorithms approach this inverse problem using physical models for the image formation combined...conference paper 2017

Haag, S.R. (author), Hoogeland, M.G. (author), Vredeveldt, A.W. (author)Instantaneous insight into the structural damage sustained by a ship running aground, can be of great aid in the decision making following such a disaster. It should be possible to distil the extent of structural damage from acceleration measurement data of the entire vessel. Such measurements could possibly even be done using a simple...conference paper 2017

(author), Loeve, D. (author)This paper presents the results of a study into the functional requirements and optimisation of the CO2 shipping chain, with a focus on the offshore offloading system. The goal was to evaluate the feasibility of a generic approach to the development of ship-based CO2 transport and storage systems in the North Sea, using a range of typical North...article 2017

(author)Naval ships have camera systems available to assist in performing their operational tasks. Some include automatic detection and tracking, assisting an operator by keeping a ship in view or by keeping collected information about ships. Tracking errors limit the use of camera information. When keeping a ship in view, an operator has to re-Target a...conference paper 2016

Ainslie, M.A. (author), de Jong, C.A.F. (author)Because of the history of sonar and sonar engineering, the concept of “source level” is widely used to characterize anthropogenic sound sources, but is it useful for sources other than sonar transmitters? The concept and applicability of source level are reviewed for sonar, air guns, explosions, ships, and pile drivers. International efforts...conference paper 2016

Sertlek, H.Ö. (author), Binnerts, B. (author), Ainslie, M.A. (author)Sound mapping over large areas can be computationally expensive because of the large number of sources and large source-receiver separations involved. In order to facilitate computation, a simplifying assumption sometimes made is to neglect the sound speed gradient in shallow water. The accuracy of this assumption is investigated for ship...article 2016
