news Tidal Current Turbine JIP launches papers


MARIN offers a wide selection of papers and doctoral theses in the field of hydrodynamics on its website at www.marin.nl.


The most recent publications include:


New guidelines for speed power trials, level playing field established for IMO EEDI H. van den Boom, H. Huisman, F. Mennen, SWZ Maritime, 2013


MARIN and Airborne Marine are initiating the first Joint Industry Project on the struc- tural and hydrodynamic design aspects of tidal current turbine blades, along with other participants. Based in the Netherlands, Air- borne Marine is a constructor of composite turbine blades. Tidal and ocean currents are the subject of interest for green energy because of their predictability and consistency. The design of tidal turbine blades constitutes a major issue for the successful introduction of reliable and productive tidal energy. The objective of the JIP is to investigate the


loads and operational efficiency of tidal tur- bine blades. MARIN plans to use its unique facilities such as the new Depressurised Wave Basin, in which environmental con- ditions and turbine-turbine interaction can be recreated, and dedicated cavitation and noise measurements can be undertaken. Further supported by CFD flow simulations, the JIP will deliver valuable information for the design of reliable turbine rotors.


Participants are welcome to join. For more information please contact Gert-Jan Zondervan, g.j.d.zondervan@marin.nl

aNyMOOR SAIL into a sustainable future


MARIN is participating in the ambitious SAIL project, which aims to develop hybrid wind propelled vessels in order to reduce emissions and fuel consumption, ultimately to achieve zero emission freight sailing. Seventeen partners from seven North Sea countries, including ship operators and knowledge institutes, are taking part in the three-year project, which will run until June 2015.


MARIN’s voyage and scenario simulation tools will be used. These are of particular interest because the performance of hybrid,

wind-based designs will depend strongly on the realised speed and power consump- tion that can be expected in real offshore wave, wind and current conditions on actual routes that could be sailed by the vessels under consideration. The project will look at the technical developments required, as well as the economic context, public-private partnerships, policy and legislation.


SAIL is an Interreg IVB North Sea Region Project, which has a budget of € 3.4 million. For more information see www.nsrsail.eu


a user-friendly interface for mooring system analyses


Mooring system analysis has just become more accessible and user-friendly thanks to recent developments.


In the past MARIN has delivered several time domain calculation programs but the main focus has always been accurate modelling of the physics and being user- friendly often came second. However, the development of a single time domain code for different applications opened the door for generating a user-friendly Graphical User Interface (GUI) to run the analysis.
