Day 18: Fieldwork at Hammars Hill wind farm, SME, Scotrenewables and Orkney College

Group 1 Summary

Today we visited Hammars Hill Wind Farm in the northeastern of the main island, across the Rousay island. Alistair Gray, the chairman, showed us an area where four wind turbin are set up. Wind energy is one of the cheapest and the easiest among the renewable energy resources in term of investment and technology. Their wind energy technology is the latest generation that able to transform the energy into electricity effectively. The device tower has 42 m in high and 44 m of blade diameter that can produce about 900 MWH and run for 20 years. They spent about 7,8 million pounds investment to set up the devices, platform, maintenance and other costs with 4 years of break even point. With price of 150 pound/ MWH, the company supplies energy throughout Orkney and mainland of Scotland.

We moved to Hatston, Kirkwall to see John McGylnn, Project Manager Orkney, at Sustainable Marine Energy. Basicly, the company provides platforms that goes along with the technology. The early challange for them were finding the method to make the device works under the water and sit under the sea surface, but not on the sea bed. They produces two platforms so far, the first generation goes with two turbins devices have 4 m each in diameter, and the second generation with larger device, consists four turbins with 16 m each in diameter. The second generation platforms has two variants, the floating one that stay in the sea surface and the one that stay under the water. The floating one which has less energy production is intended to the developing countries, and another one which produces more energy is intended to Europe, America and more aggresive countries. The company are open to build any global collaboration and partnership to expand international opportunities.

Visiting the other company nearby, Scotrenewables Tidal Power, we met James Murray, Business Development Manager, who gave an overview about the company that established the device since 2012. Through some research and investigation, they focus on creating floating tidal turbin devices because the tidal current energy decreases with increasing the sea depth. One of the devices they produce is SR 2000 2MW that can sufficient about 1000 houses power need. It becomes the world most powerful tidal turbin in the market now. Learning from wind turbin devices, the devices consists turbins or generator made of a compsite, the LV converter, and the transformer. The location criteria for setting up the devices are water depth more than 25 m, considered high tidal current, and public acceptence.

In University Highlands and Islands, Orkney campus, we met Sean Page, Marketing officer and Scott Timpany, Enviromental Geoarcheologist of Archeology Institute. They gave an overview about the study program, the facilities and recent projects they have been conducting. Scott Timpany, Environmental Geoarchaeologist for ORCA Marine, highlighted the research led investigation looking at the compostion and character of Orkney’s past woodlands through the study of submerged forest tree remains and intertidal peats in some of the sheltered bays of the Orkney Isles. He showed us the process of data collecting in the field, pollen and charcoal observation, and analyse the result.


Group 2 Summary: Visits to Hammars Hill windfarm, Suistainable Marine Energy, Scotrenewables, and University of Highlands and Islands Orkney College (OC)


Workshop I: Hammars Hill windfarm

After breakfast, we went to Hammars Hill Wind Farm at 08:50 am. We met  Mr. Alistar Gray at 09.20 am, the Chairman of Hammars Hill Energy. The Hammars Hill windfarm in Orkney has had a record beating year, producing over 20,000 MWh of electricity, equivalent to providing the annual needs of 4000 households. The five turbine windfarm was largely funded by local investors and is a very successful example of a locally owned and locally managed renewable energy project. Orkney Islands Council, the local authority, is the largest investor ( From this workshop we learn about the steps required to bridge research and implementation as well as scaling up and commercialising research output.

Workshop II: Sustainable Marine Energy Ltd, Hatstom, Kirkwall

At 10:45 am we visited the Sustainable Marine Energy and met it Project Manager Orkney, Mr. John McGlynn. Sustainable Marine Energy Ltd (SME) is a marine engineering company, focused on bringing a cost-effective solution to the tidal energy market. SME is aiming to deliver the next generation technology that will challenge the current tidal energy industry on price and performance. Based in Cowes on the Isle of Wight, SME has access to a wealth of maritime knowledge from an area steeped in marine innovation and history ( They have their next generation tidal turbine that suitable for 3 mps tidal velocity. They have constraints in developing their technology, namely money. Therefore, to build an international platform, they are very open to establish a partnership. They will start build a partnership with Singapore by doing a demonstration next year in Singapore.

Workshop III: Scotrenewables Tidal Power Ltd, Hatston, Kirkwall

We visited Scotrenewables office which placed in front of Sustainable Marine Energy office at 11:30 am. There we met James Murray, bussines development manager of Scotrenewables Tidal Power Ltd. The company was engaged in cost effective tidal and river hydrokinetic turbines. It has partnerships for turbine assembly with Harland & Wolff Shipyard, Belfast and an established supply chain for turbine construction.  In 2014, the company opened its own production facility for electrical system testing and assembly.  The company has patents protecting the key design advantages of its technology and an excellent health and safety record. In 2016, the company launched, a 2MW turbine, known as the SR2000, the culmination of more than 12 years of research, design and testing.  This is the largest and most powerful tidal turbine in the world. Talking about environment issue, Scotrenewables employ a dedicated environmental consents manager to manage the consenting and monitoring programmes associated with the company’s test turbines and developments. are committed to protecting the marine environment and to contributing to the evolving understanding of the potential environmental impacts of the SR2000 and the wider tidal industry.  Since the early prototype turbine testing, an environmental monitoring programme has been undertaken around the turbine (

Workshop IV: University of Highlands and Islands Orkney College (UHI OC)

At 12:30 am we have a free time to get our own lunch in Kirkwall, the St. Magnus Cathedral become our meeting point. After luch we went to University of Highlands and Islands Orkney College. There, Mr. Sean Page tell us about how UHI OC organizes long distance lectures using video conference technology. The advantages of using video conference technology to support long distance lectures is it can be recorded so that if something is not clear, the video recording of the lecture can be played back. After that, Dr. Scott Timpany took us to the botanical archeology laboratory. There he introduces the tools used, the activities carried out in the lab, and also some of the research publication results. He explained mainly about palaeoecological approach into the research of past natural woodland in the Scottish Highlands. The visit at this university ended around 04:00 pm and we returned to the hotel.
