2 D2.27Manual of Wave instrumentation Survey of laboratories ABOUT MARINET MARINET (Marine Renewables Infrastructure Network for emerging Energy Technologies) is an EC-funded network of research centres and organisations that are working together to accelerate the development of marine renewable energy - wave, tidal & offshore-wind. The initiative is funded through the EC's Seventh Framework Programme (FP7) and runs for four years until The network of 29 partners with 42 specialist marine research facilities is spread across 11 EU countries and 1 International Cooperation Partner Country (Brazil). MARINET offers periods of free-of-charge access to test facilities at a range of world-class research centres. Companies and research groups can avail of this Transnational Access (TA) to test devices at any scale in areas such as wave energy, tidal energy, offshore-wind energy and environmental data or to conduct tests on cross-cutting areas such as power take-off systems, grid integration, materials or moorings. In total, over 700 weeks of access is available to an estimated 300 projects and 800 external users, with at least four calls for access applications over the 4-year initiative. MARINET partners are also working to implement common standards for testing in order to streamline the development process, conducting research to improve testing capabilities across the network, providing training at various facilities in the network in order to enhance personnel expertise and organising industry networking events in order to facilitate partnerships and knowledge exchange. The initiative consists of five main Work Package focus areas: Management & Administration, Standardisation & Best Practice, Transnational Access & Networking, Research, Training & Dissemination. The aim is to streamline the capabilities of test infrastructures in order to enhance their impact and accelerate the commercialisation of marine renewable energy. See for more details.

8 1 INTRODUCTION The present report gives guidance on the instrumentation and techniques in the various Marinet facilities. The report does not provide additional guidance on best practises compared to the books that already exist (see references). Instead the report provides a survey of wave generation and analysis equipment and techniques used in existing facilities of the Marinet partners. Page 5 of 84
9 2 RESULTS OF SURVEY Results of the survey are given for the wave laboratories of the Marinet partners. Laboratory facilities are divided into flumes (appendix B) and basins (appendix C). Flumes are facilities for unidirectional wave generation where the length is much larger than the width. In the case of wider flumes sometimes segmented wavemakers are used for practical reasons, but for unidirectional wave generation only. Today most basins have segmented wavemakers with multidirectional wave generation ability. The laboratories that participated in the survey are mainly with in-house designed or Edinburgh Design wavemakers. This is not a true representation of the population as some of the major wavemaker manufacturers are underrepresented here (Bosch-Rexroth, DHI, HR Wallingford, VTI, etc.). In any case the survey gives an insight intothe many different configurations available, but this overrepresentation should be kept in mind. For example it can be mentioned that the surveys have a bias in showing that dry back is very common even for small scale facilities. This is expected to be caused by this principle being used for most Edinburgh Design wavemakers, while this is not representing an average small scale facility. The following laboratories participated: Aalborg University (B1, C1, C2, C3) University of Florence (B2) University College Cork, HMRC (B3, C6, C7) Ifremer (B5) CNR Insean (B6) University of Strathclyde (B7) ECN (C4) FloWave TT (C5) Plymouth University (C8) Queen s University Belfast (C9, C10) 2.1 OVERVIEW OF FLUMES Seven wave flumes participated in the survey ranging from deep water to shallow water facilities. An overview of the results can be found in Table 2.1 and the detailed results in appendix B. The flumes range tremendously in size as width varies from 0.8 to 12.5 m and length from 22 to 220 m. The widest and longest flumes are deep water flumes operating in the typical scale for small scale testing. However, these wide and long flumes have typical ship testing as a main working area. Typical flumes for shallow water testing are 1-3 m wide and 20 to 40 m long. For wave flumes a large part of the wavemakers use in-house built software and in several cases are without active absorption capabilities. However, most flumes operating in shallow water have active absorption capabilities or this capability is under preparation. The required time to settle down from one test to the next is in some facilities very large. This applies especially to the wide and long flumes without active absorption capabilities. This might be explained by cross-modes which are more easily developed in wide flumes than in narrow flumes. Cross-modes in flumes are in general difficult to damp due to the fully reflecting sidewalls. Page 6 of 84

11 2.2 OVERVIEW OF BASINS Ten wave basins participated in the survey ranging from deep water to shallow water facilities. An overview of the results can be found in Table 2.2 and the detailed results in appendix C. The size of the basins very tremendously, but with a quite clear tendency that basins for deep water testing are larger than basins for shallow water testing. It can also be seen that for recently built basins electric actuation is much more typical than hydraulic. With respect to paddle discretization (segment width) a typical value is m. For most wavemaker types only box mode discretization is practical. However, for the piston wavemakers two types of segmentation are possible, i.e. vertical hinged or box mode. For the same quality of the generated waves a larger segment width can be chosen for vertical hinged. It is interesting to see that the survey shows that for facilities working at approximately the same scale the used segment width is not larger for facilities with vertically hinged paddles compared to facilities with box mode paddles. This seems to indicate that the vertical hinged type is in most cases not selected to reduce investment costs, but instead to improve quality of waves for the same investment. Moreover, it appears that today most basins have active absorption systems, while in the survey by Mansard et al. (1997) this was only available in approximately half of the basins. Active absorption is typically much more important in flumes, but the survey shows that it is more typical to have this capability in basins instead of flumes. This is probably because in-house machine and software is much more typical for flumes than in basins. Finally it appears that reflective sidewall configuration (6 labs) is more typical than absorbing (1 lab) and reflecting/absorbing sidewall (2 labs) configuration. The advantage of the fully reflective walls is that space is not wasted on absorption elements and no diffraction effects exists for head-on unidirectional waves. The absorbing walls are very effective in dampening radiated and reflected waves from models which otherwise will re-reflect at the sidewalls and disturb the wavefield. Another advantage of the absorbing sidewall is that cross-modes are damped so they never reach a critical level. A configuration of reflective and absorbing sidewalls is a compromise used in two of the tested basins. One basin uses wavemakers with active absorption on all boundaries. In this case it is a circular basin, but it could as well be a rectangular basin with wavemakers on several sides. It is a costly solution, but gives also several advantages in terms of control of the wave field. The disadvantage might be that dampening of high frequency wave components is typically not as good as with a passive absorber.

13 3 CONCLUSIONS AND RECOMMENDATIONS The conclusions are: Facilities very tremendously in size and capabilities. Facilities for deep water testing are typically much larger than other facilities. This applies especially to the flumes with ship testing as the main working area. Commercial software is available in all basins, while in-house software is very common in flumes. Most basins have active absorption capabilities. The same applies to most shallow water flumes. Flumes working in deep water usually deal with short tests or structures reflecting only a small part of the energy. This is probably the reason for active absorption not being typical in these facilities. Wavemaker type is chosen dependent on water depth. Hinged wave makers are typical in deep water facilities and piston wavemakers are typical in shallow water facilities. These choices reflect the best reproduction of the target velocity profile to minimize nearfield disturbance. Segmentation in wave basins is a compromise between investment costs and quality and capabilities in terms of oblique and short-crested waves. In coastal facilities vertical hinged pistons are in some cases used to improve wave quality for the same costs. Fully reflective sidewalls are more typical for the basins in the survey (60%) than absorbing or partly absorbing and partly reflecting (30%). Active absorption on all boundaries is used in one facility (10%). All flumes and basins measure waves with wave probe arrays, but a few basins are additionally able to use other methods like η-u-v array and mapping of entire wave fields. Page 10 of 84
