Low-aspect ratio appendages for wind-assisted ships

Wind propulsion for commercial ships has been identified as a key component in the energy transition for the maritime industry. The sailing hybrid ship will operate with leeway (drift) angles to produce a lateral force known as sideforce, for steady operation under sail. In this paper, experimental results for the sailing performance of ships...

Sailing Efficiency and Course Keeping Ability of Wind Assisted Ships

Work Deck Evaluation

To provide security at sea and to provide security from the sea the Royal Netherlands Navy (RNLN) has a fleet consisting of different kinds of vessels in several classes. One class of vessels is the Alkmaarklasse Mijnenbestrijdingsvaartuigen (AMBV), the Alkmaar class mine countermeasure vessels. These vessels are starting to show their age and...

A Packing Approach for the Early Stage Design of Service Vessels

Naval architects often say that every ship is a compromise between many conflicting requirements. This widely-held belief immediately raises the question as to what kind of ship and, therefore, what kind of compromise, would suit the ship owner’s interest best. The approach presented in this thesis aims to improve the early stage design process...

Computational Cavitation Analysis of a Submerged Body at Different Depths

Transient's analysis is performed to determine the cavitation inception on a submerged body and flow dynamics under different working conditions. Cavitation causing hydrodynamic, structural and noise problems is essential to avoid. Cavitation analysis is done for a particular geometry to investigate the location and determine the critical...
