Roermond, the Netherlands 20 April 2018. Sif Holding N.V. announces today that it has been awarded the production of 77 monopiles (68 Kton) for the Borssele III & IV offshore wind farm. Borssele III & IV is developed by a consortium (Blauwwind II) comprising Shell, Eneco, Van Oord, and Diamond Generating Europe, a wholly owned subsidiary of Mitsubishi Corporation. The contract has been awarded by Van Oord as the EPCI contractor for the project and is subject to financial close.

Offshore wind energy is becoming increasingly popular in Japan. However, Japanese and other Asian harbours are currently not equipped to deal with the large number of offshore wind foundations. There are just a handful of harbours that can carry the weights of offshore foundations heavier than 1,000 tonnes without requiring significant adjustments and investments.

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.

BLUE Piling Technology by Fistuca is an innovative technology that uses a combusted gas mixture to propel a column of water upwards. The column of water pushes the monopile down as it shoots up and drives the monopile further into the sea floor as it falls back down. The pile-driving technology produces much lower noise levels than conventional pile-driving and also minimizes fatigue to the foundation. The project will result in a direct reduction to the costs of installing wind turbines.

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.  

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.
