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 2015. 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 aim of the initiative is to streamline the capabilities of test infrastructures in order to enhance their impact and
accelerate the commercialisation of marine renewable energy. See www.fp7-marinet.eu for more details.

EXECUTIVE SUMMARY Open Ocean Energy Ltd. (OOE) were granted MaRINET funding to undertake optimisation tests of their device, the
Tidal Flyer. The Tidal flyer prototype (not tested under MaRINET) is made up of 10 arrays which travel between 2
cables around pulleys to generate power. The tests under MaRINET specifically investigated the forces acting on 1
array with 6 degree-of-freedom sensors to obtain lift and drag forces for the lifting foils.
In addition, these tests were designed so that the exact centre of pressure of the main foils could be obtained for
various self-trimming tail locations. The exact position of the centre of pressure is necessary for the self-trimming
tail to control the angle of attack of the main foils effectively. The tests were a success with all of the above data
being recorded which will allow OOE to develop the Tidal Flyer system for the next stage of development. The
results have also indicated areas of the design which can be improved before the next stage.

1.2.2 Plan For This Access
The objective of the tests conducted in September 2012 (not under MaRINET) was to obtain the power curve for the
system; the proposed tests under MaRINET had a greater emphases on research of various aspects of the device.
The proposed tests, under MaRINET, focused on research into the component parts to improve the efficiency of the
device by optimising the different components. All of this knowledge will go towards improving the system to
ensure its viability.
We will test, in water, for lift and drag forces on a single array in a frame using a '6-degree of freedom' sensor to
better understand the relationship and differences between the air and water fluid mediums. This will allow us to
transfer all of the tests conducted in the Wind Tunnel into useful data for the actual system to be developed for an
ocean environment. The vast majority of existing data for aero- and hydrofoils is either for significantly different
Reynolds Numbers (aero-foils) or for very different planforms (rudders and keels). It is therefore necessary to obtain
the data relative to our hydrofoils in the kind of velocities we will operate in.
We will investigate the size, profile and number of tails to be used in each array. The theory suggests that a tail,
which has an area of 10% of the foils, should be sufficient to control the foils if located at the centre of pressure
which is also designed as the centre of mass for each array. Initial tests in this area has suggested that a tail of 20% of
the foil area is more appropriate (or 2 tails of 10% each) but greater understanding of the centre of pressure and its
precise location now suggests that the original theory needs to be investigate again for our system.
In addition, we will also conduct further tests on the exact centre of pressure for the various different cambered foils
as presented above along with the effects of, mass balancing or having an mass imbalance for each array.

2 OUTLINE OF WORK CARRIED OUT
2.1 SETUP
2.1.1 The '6-Degree of Freedom' load cells
As this tests were essentially optimisation tests, very similar tests were conducted throughout the week with slight
changes to the equipment for every test. In order to achieve this, it was only possible to test one flyer (i.e. a pair of
foils with either one or two tails in a frame). This meant that the tests were going to be static tests which are
different to dynamic tests of the full system but for optimisation, static tests are essential to understanding.
Discussions with the staff at Ifremer were held at an early stage to ensure that a single flyer could be fixed within 2
No. '6-degree of freedom' load cells; one at the top and one at the bottom. Figure 1 shows to top load cell with the
top of the flyer and the angle reader. The top load cell and coupling is shown in detail in Figure 2 below.
Fig 1 - Flyer attached to top load cell Fig. 2 Top load cell and coupling
The Ifremer staff devised a way to insert and remove a flyer without having a diver in the water which saved time
and allowed the tests to continue smoothly. The essential design criteria was that the system had to be free to
rotate and that the forces produced, would be measured in 6 directions. Special couplings were incorporated
between the top load cell and the flyer and between the bottom load cell and the flyer that allowed this design
feature.

Page 10 of 27
The top load cell was securely fitted to the underside of an 'H' Beam, which itself was clamped between 2 No. 'H'
beams spanning the tank. The bottom load cell was securely fixed to a 'U' Channel which spanned the bottom of the
tank and was securely fixed to each side of the tank.
Fig. 3 - I & H Beam set-up Fig. 4 - Flyer connected to bottom load cell
It was then simply a case of slotting the flyer into the couplings and tightening the equipment before the tests could
begin.

2.1.2 The Flyers
As indicated in Figure 4 above, each flyer is comprised of a pair of foils located between 2 flat plates. The distance
between the foils is equivalent to 3 chord lengths. Above and below the foils are self-trimming tails positioned
centrally and behind the foils at varying distances (as part of these tests).
The two main elements of the tests were to determine the exact centre of pressure and to determine the best
position of the tail (behind the foils). From previous observations and tests in the Ifremer tank, the approximate
position of the centre of pressure was known but without conclusive data, the exact position was not known. It was
decided to investigate 3 different centre of pressure positions in combination with 3 different tail positions.
This led to 3 separate flyers being assembled, each one with a different configuration as shown in Table 1 below.
The first 3 flyers were assembled for Tests 1 to 3 inclusive. The intention being that once Tests 1 and 2 were
completed and while Test 3 was underway, the configuration for Test 4 could be assembled and made ready. each
test continued in this fashion. Each piece of equipment which corresponded to either a Tail Position or a Centre of
Pressure position was colour coded to avoid any confusion in changing parts over between flyers.
Due to time constraints, it was not possible to test different cambers for the main foils and this will have to form
separate tests in the future.
2.2 TESTS
2.2.1 Test Plan
As discussed in Section 1.2.2 above the aims of these tests were to collect Lift and Drag forces, in addition to the
various moments acting on a flyer and to look at these forces for the various configurations described in Section
2.1.2 above. The set up by Ifremer staff ensured that all tests would generate the force and moment data required.
The preparation of the different flyers assemblies would ensure that the various configurations would provided
enough information to determine the best location for the tail, whether one or two tails was required and to
determine the exact centre of pressure for this flyer configuration (camber, planform, etc.). The following matrix of
tests was developed, as presented in Table 1 below.
Test No. Tail Position Centre of Pressure
Test 1 1 1
Test 2 2 2
Test 3 3 3
Test 4 1 2
Test 5 2 3
Test 6 3 1
Test 7 1 3
Test 8 2 1
Test 9 3 2
Table 1 - Matrix 1
This series of tests was conducted with 2 tails (as shown in Figure 4 above). The matrix was repeated for the 2nd
serves of tests with just 1 tail (the top tail) which were Tests 10 to 18 inclusive.
Infrastructure Access Report: Tidal Flyer Junior
Rev. [Revision Number, e.g. 01], [Pick the revision date]
Page 12 of 27
The Tail and Centre of Pressure positions were:
Item Measurement
Tail Position 1 1.2x Chord
Tail Position 2 1.3 x Chord
Tail Position 3 1.4 x Chord
Centre of Pressure 1 45%
Centre of Pressure 2 47%
Centre of Pressure 3 49%
Table 2 - Positional detail
For example: Tail position 1 had the pivot of the tail 1.2 x Chord length behind the main pivot of the foils and Centre
of Pressure 1 was where the main pivot was located 45% back from the nose of the foils.
The tests outlined above (Tests 1 to 18 inclusive) were the main body of tests. However, to understand the results
fully, other, associated tests were required and these were conducted on the last day of testing. These were:
1. Tail position in regard to top or bottom being a better position (Test 19);
2. Non-Mass Balanced test (Tests 1 to 18 were conducted with the flyers mass balanced)(Test 20);
3. Drag Test - Flyer without main foils (Test 21);
4. Lift Tests - Flyer with foils but without tails (where the foil angle was manually varied)(Tests 22, 23 & 24);
5. Drag Test - with tail set at various angles (Tests 25 & 26).
In all tests (unless otherwise specified), the tail angle was set to 15 degrees.

3 MAIN LEARNING OUTCOMES
3.1 PROGRESS MADE Comparing the Achievements against the plan for the tests, approximately 95% of the plan for the tests was
completed. While the analysis is still being undertaken in regard to the results obtained, OOE now has the raw data
with which to make decisions in regard to the optimum design for the Tidal Flyer system. Our understanding of the
Lift and Drag forces involved in a static system including the magnitude and direction of those forces is significantly
greater than prior to the tests.
In addition, with the number of varying positions for the centre of pressure and the varying tail configurations
(position and number), we can now make an informed decision as to the optimal location for the main shafts and the
number and position of the tail(s). We did not look at different tail profiles and this will have to be undertaken in
future tests.
The analysis of the raw data will continue.
3.1.1 Progress Made: For This User-Group or Technology
It is considered that the most crucial piece of the design of each array is the location of the centre of pressure, which
is where the main shaft is located. The main shaft is the point of rotation of the main foils. From these tests, OOE
have gained the knowledge of where the centre of pressure is located which varies depending upon the location of
the self-trimming tail and various positions of tail location were tested too and therefore, a considerable amount of
data was obtained.
It was also learned that the location of the centre of pressure is an exact location and that a few millimetres either
side of the exact point can have a significant effect on the forces produced. Of course this tolerance will grow as the
system is scaled up in size but with the exact location obtained, all future systems can be designed with optimum
performance in mind in regard to this aspect.
3.1.1.1 Next Steps for Research or Staged Development Plan – Exit/Change & Retest/Proceed?
It is considered that that next step for the research is to examine how the system can be scaled up to a 1/8th or
1/4th scale prototype model. With the increase in size and (more than likely width), a suitable site will need to be
found for this type of system. In addition, it will be necessary for OOE to raise money to develop the system for the
next development stage.
3.1.2 Progress Made: For Marine Renewable Energy Industry
It is understood that the tests undertaken by OOE at IFREMER were the 1st of their kind and therefore, the
knowledge gained in this process can be made available to other companies who which to look at similar devices or
with parts of systems with similar characteristics.
In addition, the test set up was unusual in that we had a rotating shaft which was connected to 2 No. '6 degree-of-
freedom' load cells; one at the top and one at the bottom, which was the 1st time that type of configuration was
used at IFREMER and the set up and tests with this configuration was a success.

3.2 KEY LESSONS LEARNED • Record as much data as possible;
• Use video recorders at all times and as many as you can manage to record the tests from different angles (as
appropriate). If possible also have a method to synchronise video with raw data.
• Make your own notes in regard to recorded data; do not just rely on the electronic recording of data which
usually does not allow for observations.
• Discuss the tests with the team and with IFREMER staff as they are being undertaken to develop a deeper
understanding of potential improvised changes to the test rig for future tests.
• Make sure to have enough personnel for all the tests you want to undertake including making changes
between tests.
