SMOOTH Seakeeping & Manoeuvring


Recently, MARIN concluded the sea- keeping and manoeuvring model tests for the SMOOTH EU project.


On September 1st and 2nd, the first conference on Advanced Model Meas- urement Technology for the Maritime Industry was held at the École Centrale de Nantes.


The two-day event was organised by the Hydro-Testing Alliance, a network of excel- lence that is supported by the European Commission’s Sixth Framework Programme. The Hydro-Testing Alliance (HTA) network aims to improve and accelerate the hydro- dynamic measurement technology develop- ments of the 18 European-member organi-


sation. MARIN is coordinator of the HTA and has 11 researchers active in the various programmes. AMT’09 welcomed over a 100 people, mostly from EU countries but also from the USA, Canada and South-Korea. In total, 35 presentations were held on subjects rang- ing from high speed video, Particle Image Velocimetry to free-running model control and pod thruster drives on scale models. The next HTA activity is the Second Sum- mer School in Norway. More information will be provided in a few months on www.hta-noe.eu.


This project aims to achieve energy efficien- cy gains through the application of air bubble lubrication and through advanced coatings. In this technique, air is injected from various locations under the ship in a bid to reduce frictional resistance. Addition- ally, special coatings are used to improve the effect. Along with other ongoing research, MARIN performed model tests to determine if this type of air lubrication has an influence on seakeeping and manoeuvring behaviour. Free sailing tests in the Seakeeping & Manoeuvring Basin were conducted with a model that featured a comprehensive air injection system.


Results show that air lubrication has minimal effect on manoeuvring and no noticeable effect on seakeeping behaviour. A paper, which also includes results on powering and full-scale tests, was present- ed at the 2009 SNAME Annual Meeting & Expo (see www.marin.nl for download).

MARIN aims to be ADEPT at reducing ship emissions


MARIN joined the Dutch Advanced Ener- gy and Emissions Concepts on Ships Operating in the Coastal Zone (ADEPT) project, which runs from 2009 until 2011. The goal is to reduce ship emis- sions to at least the levels required by IMO Marpol Tier III and IV (to apply in 2011 and 2016 respectively) and to increase fuel efficiency.


The following tasks are planned to achieve the objectives: - Selection of new technologies for energy production and emission mitigation systems


- A service based design approach to integrate the systems in the ship design


- Comprehensive voyage simulation technology to assess the new designs. MARIN’s contribution here is to employ its Gulliver voyage simulation tool alongside TNO’s GES energy simulation tool. Other participants in ADEPT are: Alewijnse Marine Systems, Damen Shipyards Group (project leader), MTI Holland, Conoship International, Delft University of Technology, Netherlands Defence Academy, TNO Built Environment and Geosciences, Wärtsilä Netherlands and Sastech. Project coordina- tion is done by CMTI.
