Welcome and purpose

Welcome readers, I am very glad to start this blog, my name is Irene and I am a 23 years old naval engineer from Barcelona. Currently, I am doing my Master in Hydrodynamics for Ocean Engineering at École Centrale de Nantes. Since I was young I had a huge interest in sciences, technology and engineering. […]

Stability analysis of a fishing vessel

The purpose of this work is to analyze the intact stability of a 18 meter length French flagged fishing vessel. For this aim, the parameters of influence over the stability will be analytically computed for a later comparison with the ones obtained through the software Maathydro++. After the results validation, these parameters will be evaluated […]

CFD software approaches and nummerical methods used within ocean engineering

Hydrodynamics is the branch of fluid mechanics that studies the motion of isovolume fluids and the forces acting on solid bodies inmersed in it. These analysis is performed in order to find the solution of problems like the formation of freak waves and its impact with structures. Usually, the definition of these problems implies a […]

Infusion system design for a composite material sailboat hull

Introduction The implementation of composite materials within the naval industry involved a great change and improvement. It opened a wide range of possibilities, some yet to be discovered, of new materials that can be created in function of its later application. With the passage of time, composite materials gained relevance over the conventional ones used […]

Stability calculation of a grounding in a ship model basin

Basic theory of stability The Archimede’s principle is the main basis of ship stability; it states that the weight of a floating object is equal to the weight of the displaced water. In the case of a grounding, when an end of a ship comes into contact with the ground or a rock, at this […]

Optimization of the bulbous bow by means of CFD analysis

The wave resistance is generated due to the navigation of the ship across the free surface of the water. This phenomenon is mainly influenced by the effect of gravity in contrast to the effect of viscosity, therefore this last one can be neglected in order to simplify the computation time. This simplification is done by […]

Propulsion in double-ended ferries

Double-ended ferries belong to the class of the RoPax ships and as well as regular ferries, they are manly used to transport car and passengers carrying out multiple trips per day. Therefore, the efficiency in its operations is an important factor since it has a great economical impact. This requirement is the reason of designing […]
