Ramón Quereda y Cristina Soriano, from ‘El Pardo Campus’ of INTA, were the winners of the first prize of the 57th Congress of Naval Engineering and Maritime Industry, organized by the Association of Naval and Ocean Engineers of Spain, held at the facilities of the Port Authority of Valencia from October 23 to 26, 2018.
The Association of Naval and Ocean Engineers of Spain (AINE) organizes each year the Congress of Naval Engineering and Maritime Industry in a different location in Spain. This year 2018 has been the edition number 57 in Valencia, with the presentation of papers covering various topics, among which we can highlight the geometric definition of the sections of the blades of a propeller, unmanned boats, measurements of the forms of a ship through laser scanning, propulsion systems with performance improvements, ship repair and vessel operability.
In this occasion INTA was represented by Ramón Quereda, naval engineer PhD, who presented the work entitled "CRP-POD propulsion system on future ships ". The naval engineers Juan González-Adalid and Mariano Pérez Sobrino, from SISTEMAR, and Cristina Soriano, from INTA, are also co-authors.
The Professional Technical Committee of AINE selected 14 papers among all the applications received and awarded three of them. The prize for the best paper presented at the congress went to Ramón Quereda. The paper highlights the advantages of a propulsion system with two aligned propellers rotating in opposite directions with the stern propeller installed in a POD. The energy recovered by the rear propeller increases the performance of the system, reducing fuel consumption and reducing the emission of CO2 into the atmosphere. This propulsion system was tested in El Pardo, and it was necessary to design and manufacture special devices for revolutions, torque and thrust measurement in the POD propeller during the open water and self-propulsion tests.
