VALIDATION OF DUCTED PROPELLER DESIGN AND ANALYSIS TOOLS Authors: Huisman, J., Garenaux, M., De Jager, A. and Janse G. Conference/Journal: Working paper Date: May 17, 2021 Recently, a study was done on the validation of the design and analysis tools for ducted propellers. The validation was done using full-scale observations on board the TSHD Bonny
CFD INVESTIGATION OF THE EFFECT OF WATER DEPTH ON MANOEUVRING FORCES ON INLAND SHIP AuthorsOud, G., Bedos, A. Conference/JournalConference on Computational Methods in Marine Engineering (Marine 2021) DateJun 2, 2021 As part of a research program focusing on shallow-water manoeuvring of inland ships, a set of model tests is reproduced using CFD techniques. The aim
ON THE CONTRIBUTION OF ROUGHNESS EFFECTS TO THE SCALING OF SHIP RESISTANCE AuthorsEça, L., Starke, A.R., Kerkvliet, K., Raven, H.C. Conference/JournalConference on Computational Methods in Marine Engineering (Marine 2021) DateJun 2, 2021 Roughness effects are one of the main challenges of the prediction of ship resistance using traditional model tests and extrapolation procedures. Computational Fluid
Pushboat design considerations facing climate change Pushboat operators, especially those operating on the rivers, face the transition to zero emission propulsion in combination with longer periods of low water. This results in conflicting design specifications. By combining different disciplines, MARIN is extending the scope of its design support to cope with this challenge. Autonomy
AuthorsToxopeus, S., Kerkvliet, M., Vogels, R., Quadvlieg, F., Nienhuisz, B. Conference/JournalConference on Computational Methods in Marine Engineering (Marine 2021) DateJun 2, 2021 Traditionally, submarine hydrodynamic design has focussed mainly on requirements regarding operational range, powering performance and manoeuvring ability for deeply submerged conditions. To improve the effectiveness of the boat, attention is also paid to
Farwind has led to the development of a multihull that is fully propelled by the wind. And as it sails, water turbines underneath are powered to generate electricity. The harvested energy is stored on board and brought to shore. Farwind design concept At societal level, such a project could make a big impact
SafeTrans as a Service! Voyage simulations are an important aid in design choices, operational decisions, risk assessments, schedule predictions and many other activities. With increasing standards regarding safety, fuel consumption/CO2 emissions and scheduling accuracy, combined with increasing computational power, the significance of simulations in the maritime sector’s daily practice keeps growing. Within a Joint Industry
SCREENING WAVE CONDITIONS FOR THE OCCURRENCE OF GREEN WATER EVENTS ON SAILING SHIPS AuthorsEssen, S.M.van, Monroy, C., Shen, Z., Helder, J., Kim, D., Seng,S., Ge, Z. Conference/JournalOcean Engineering DateAug 15, 2021 Volume234 DOIhttps://doi.org/10.1016/j.oceaneng.2021.109218 Design loads for extreme wave events on ships, such as slamming and green water, are hard to define. These events depend on
Can bridge simulations support conceptual design? Within the EU Horizon project Holiship, MARIN has developed, together with partners, a Virtual Vessel Framework (VVF) in which real-time bridge simulations can be used to make key decisions in the concept design stage. This VVF can lead to a better performing ship or cost reductions. Figure 3: Bird-eye view
