In a significant advancement for offshore wind energy, Van Oord completed the installation of three monopiles using a silent method at the Hollandse Kust West wind farm. This intervention marks the first time this technique has been applied on a commercial scale within the sector.

Additionally, the operation was carried out using the vessel Boreas, designed for offshore installation work. The project is part of a larger development that includes the installation of 52 foundations in total.

VibroJet technology and controlled vibration

Furthermore, the installation was supported by GBM Works' VibroJet technology, combined with CAPE Holland's vertical vibration tools. This system reduces soil resistance through controlled water injection and vibrations.

The process also allows monopiles to penetrate the seabed with less mechanical effort. This technique is particularly effective in areas with dense sand layers, such as the North Sea.

Reduced impact on the marine environment

In this context, one of the main objectives of the method is to reduce underwater noise generated during installation. This factor is crucial for protecting marine species sensitive to acoustic vibrations.

In fact, data collected during the operation will be used to validate predictive models on underwater sound behavior. This opens the door to wider adoption of solutions with lower environmental impact.

Collaboration among offshore sector stakeholders

At the same time, the project reflects coordination among multiple companies in the sector. Van Oord leads the execution, while GBM Works provides the VibroJet technology and CAPE Holland contributes with vibration systems.

Meanwhile, Ecowende, a joint venture of Shell, Eneco, and Chubu, is driving the development of the wind farm with a focus on sustainability and biodiversity.

Hollandse kust west and its energy contribution

As for the wind farm, it is located approximately 53 kilometers off the coast of the Netherlands and will have a capacity of nearly 760 MW. This production will cover about 3% of the national electricity demand.

Furthermore, the wind farm is expected to be fully operational by the end of 2026, consolidating its role in the expansion of offshore wind in Europe.

Boost for new practices in offshore monopiles

Finally, this advancement reinforces the development of monopile installation methods that are more compatible with the natural environment, driven by initiatives from companies like Van Oord. The combination of technical efficiency and impact reduction positions these solutions as a benchmark within the sector.

Consequently, the offshore wind energy industry continues to move towards more sustainable execution models adapted to current environmental challenges.

Oman refining production up in early 2026

Refinery production in Oman grew by 11.1% in the first months of 2026, driven by higher volumes in fuels such as diesel, aviation fuel, and naphtha. This increase reflects greater activity in the sector, with increments in both sales and exports across several key categories.

Diesel led the growth with a significant rise in production and exports, while aviation fuel also advanced strongly, supported by the recovery of air traffic. Other products such as liquefied gas and naphtha showed positive figures, although some segments experienced declines in sales or production, indicating mixed performance in certain areas.
