Sif manufactures steel foundation piles (monopiles) for oil and glass platforms and offshore wind farms. We supplied 136 steel tubulars for the foundation jackets for the Beatrice Offshore Wind Farm, which were installed by Seaway Heavy Lifting (SHL) in the North Sea off Scotland.
In collaboration with various parties in the wind sector, including Sif Netherlands, this week the Dutch Government launched an international campaign entitled Wind & Water Works. This campaign was launched during an offshore wind energy masterclass organised by the Netherlands for ten guest nations. The name of the campaign conveys a clear message and reflects the expertise and professional approach of Dutch companies and government bodies in the field of wind energy at sea. Wind & Water Works demonstrates how Dutch companies are now applying their offshore expertise developed over many years to offshore wind energy.
Tuesday the 31th October we had a visit from the board members and management of Norther Offshore Wind Farm. The shareholders in this project are all parties with the necessary expertise and experience in developing renewable energy projects. Norther is ultimately owned by three parties: Elicio, Eneco, and Diamond Generating Europe.
Humans have been harnessing the power of wind for more than 2,000 years. But the use of wind to generate electricity is a more recent phenomenon. And this development is now beginning to bear fruit. Grid parity has now been achieved, which means that the cost price of offshore wind is the same as for energy obtained using fossil fuels. But there is no end in sight to the development of wind energy and other renewable energy sources.
The development of Centre Line Alignment for welding cans of large diameter tubulars is an exciting proposition for designers. This development allows for more weight-efficient designs, as the magnitude of any change in wall thickness may be increased and the design stresses associated with plate thickness transitions are reduced to yield longer design fatigue lifetime.
