Prof. Rumen Kishev (Bulgarian Ship Hydrodynamics Centre)21/06/2018, 11:00Environment protection, electric system and ship energy efficiencyPaperBack in 2012, in its attempt to limit excess fuel consumption and green gas emissions respectively, IMO distributed MEPC.212(63) Resolution for calculation of the attained Energy Efficiency Design Index (EEDI) for new ships, which became mandatory since 2013. Attention has been paid to the account of the environment caused speed reduction, as directly related to the real operational...Go to contribution page

Federica Piastra (Cetena S.p.A.)21/06/2018, 11:15Environment protection, electric system and ship energy efficiencyPaperThe awareness of ship’s energy efficiency is undeniably one of the top priorities of ship-owners, designers and operators; the aim is to comply the continuously updated regulations and to optimize the configuration of electrical machineries and their consumptions to reduce emissions and costs. Therefore also monitoring systems, historically connected to the ship structural condition, have been...Go to contribution page

Prof. Blagovest Belev (Author)21/06/2018, 11:30Environment protection, electric system and ship energy efficiencyPaperThe International Maritime Organization (IMO), through its Maritime Environmental Protection Committee (MEPC), has been carrying out substantial work to provide the fundamental conditions for the reduction of greenhouse gas emissions from international shipping since 1997, following the adoption of the Kyoto Protocol and the 1997 MARPOL Conference. Many documents, issued in this respect, are...Go to contribution page

Prof. Carl-Erik Janson (Chalmers University of technology)21/06/2018, 11:45Marine renewable energyPaperA benchmarking activity of numerical methods for analysis of Wave Energy Converters (WEC) was proposed under the Ocean Energy Systems (OES) International Energy Agency (IEA) Task 10 in 2015. The purpose of the benchmark is to do a code-2-code comparison of the predicted motions and power take out for a WEC. A heaving sphere was used as a first simple test case. The participants simulated heave...Go to contribution page

Dr Mauro Bonfanti (Politecnico di Torino)21/06/2018, 12:00Marine renewable energyPaperIn this work, we address the use of Hardware In the Loop test rig for renewable energy application. Such test rig is designed to evaluate the performances of the wave harvesting system called ISWEC. The ISWEC is a floating, slack-moored, gyroscopic Wave Energy Converter. The full-scale prototype has an electric-mechanical Power take-off (PTO) composed by a gearbox and a brushless torque...Go to contribution page

Mr Sergej Antonello Sirigu (Politecnico di Torino)21/06/2018, 12:15Marine renewable energyPaperISWEC (Inertial Sea Wave Energy Converter) is an offshore pitching floating device designed to exploit wave energy through the gyroscopic effects of a spinning flywheel. The annual productivity of the ISWEC is strictly connected to the hydrodynamic performance of the floater, that represents the first step in the energy conversion chain. The hydrodynamic performance can be described by the...Go to contribution page

Mr Nicola Pozzi (Politecnico di Torino)21/06/2018, 12:30Marine renewable energyPaperNowadays, atmospheric pollution and climate changing have encouraged Governments to invest in renewable technologies for clean energy production. Wave Power constitutes an interesting option in the panorama of renewables and starting from the first results achieved in the ‘70s, in the last and present decade the major efforts have been concentrated to make Wave Energy Converters (WECs) more...Go to contribution page
