Wind energy offers many advantages, which explains why it's one of the fastest-growing energy sources in the world. In Europe alone, the installed wind power is expected to reach 213 GW by 2020 according to the European Wind Energy Association (EWEA). The growth is driven by the upward trend in energy prices, and by national and international legislation aiming at de-carbonization of the energy sector to abate global warming and to obtain security of energy supplies.
This article focuses on how Scan can help wind turbine manufactures test new blade designs.
Static proof test
Generally, wind turbine blades are shaped to generate the maximum power from the wind at the minimum construction cost. Therefore, new- and more efficient blades are coming fast to the market. When a new blade is designed the prototype is thoroughly tested by the manufacture or a blade test center. The test program covers extreme loads to demonstrate that the blade can withstand all operational load conditions such as simulating the forces of a storm.
Scan winch blade test equipment
We have extensive experience, designing, manufacturing, testing and installation winches for static test of wind turbine blades with multipoint pull. We carefully plan and design the equipment to load the blade in the right manner and not to overload it.
“We use our more than 60 years of experience within the winch industry when we help our customers with winch solutions for static test” says Michael Vejlgaard, Managing Director of Scan.
Our static test winches may be carried out as a multipoint load application or a single point load application. The loads are introduced in all points simultaneously. Furthermore, the load may be applied in horizontal or vertical direction. The winch setup is designed to be very flexible, and can easily be moved to a new position.
Our winch equipment is designed to carry out both in-house tests as well as field tests. Scan offers a wide variety of services:
10 years for green conversion. Reduction in greenhouse gas emissions by 70 percent. That was the government's decision in 2020. It put a lot of pressure on the Danish district heating plants, which had to change their heat production from black to green. But not for Hvide Sande District Heating. They were already far ahead in their green transition.
In fact, we must go all the way back to the year 2010. Already by that time, they had seen a great business potential in the green transition. Therefore, they contacted Scan to find out if our boilers could contribute to their vision of providing sustainable and cheap heat for their customers.
After a thorough project analysis, the conclusion was clear. It would be a good financial investment for Hvide Sande District Heating to have an electric boiler installed. At the same time, it would also reduce their CO2 emissions. They ordered a 10MW electric boiler from Scan and started the green conversion. Since then, the boiler has been connected directly to 3 wind turbines. Today, it is an important heat source for the city. For example, from August 2019 to July 2020, the electric boiler produced 28,880 MWh and 2,880 full load hours. When taken the heat loss into account, the electric boiler supplied heat to 1,600 households in Hvide Sande.
“The electric boiler has been a really good investment for us and has been an important piece in our green transition. The best thing is that, in addition to the annual service, there is almost no maintenance on the plant. We pass by occasionally to check that it is running ok and otherwise it fits itself. It has gone quite well, seen in the light of how much we use the system” says Operations Manager, Martin Halkjær Kristensen from Hvide Sande District Heating.
The world’s biggest wellboat operator, Sølvtrans, plans to have 20 ships built over the next five years at a price of around £647m. Recently they have ordered 3 vessels from the Norwegian shipbuilder Aas Mekaniske Verksted.
Norwegian shipbuilder Aas Mekaniske Verksted is a shipyard with long traditions and recently the yard has specialized in designing and building live fish carriers for the fish farming industry. Over the years, Aas Mekaniske Verksted have designed and built several vessels for the Norwegian company Sølvtrans.
Sølvtrans is the world's largest wellboat company for transport of live salmon and trout. They operate 16 wellboats in Norway, Scotland, Tasmania and Canada. Sølvtrans states that quality is of most importance when they build our boats. They want the best equipment delivered from suppliers with the most innovative and sustainable solutions.
Scan has been awarded a contract to deliver auxiliary equipment to three wellboats that the shipyard is building for Sølvtrans. This follows several earlier deliveries of auxiliary equipment to Sølvtrans and Aas Mekaniske Verksted.
“We’re pleased to have entered an agreement with Aas Mekaniske Verksted on delivery of winches for their new buildings. We see this as a declaration of confidence and confirmation of our quality.” says Michael Ørts Vejlgaard, Managing Director for Scan.
“This large delivery underlines our position as manufacturer of high-quality winches, and we take pride in being a favored supplier to them”, adds Michael.
Due for delivery in 2022, the three new Sølvtrans vessels are of Aas Mekaniske Verksted’s own design. The well boats have a loading capacity of 3000 m3 and is designed for smolt transport and dewatering system for freshwater treatment of the fish. The 76-meter vessel has a cargo volume of 3000 m3 which provides a carrying capacity of 400-450 tons of live fish.
