De Bock Maritiem
Ship management and
seamless sea-river logistics
De Bock Maritiem is a young and ambitious shipping company specializing in dry cargo vessels with low air drafts and shallow drafts.
From its base in Alkmaar, the company focuses on sea-river shipping, a seamless and efficient transport method that combines coastal and inland waterways without transshipment. This saves time, reduces costs, and minimizes cargo damage, offering clear advantages to clients. With a modern fleet and a commitment to innovation, De Bock Maritiem is charting a course toward a more sustainable and efficient future in sea-river logistics.

Wind on
the radar
Gilbert met Frank Nieuwenhuis of Econowind years ago. He monitored the development and results of the company closely. After considering various wind-assist technologies Gilbert ultimately chose VentoFoils for their practicality and efficiency.

Econowind
“Compared to alternatives in the market, VentoFoils are lighter and can fold to pass under low bridges, which is essential for river navigation,” Gilbert notes.
Their integration into the newbuild’s modular diesel-electric setup further aligns with De Bock Maritiem’s strategy for future adaptability. The modular design also allows the vessel to incorporate future technological advancements, such as alternative fuels or additional energy-saving measures.

“The maritime industry is evolving, and we must evolve with it. VentoFoils offer a practical solution for improving efficiency and reducing emissions, helping us future-proof our fleet while maintaining our commitment to innovation.”

Installation
process
The VentoFoils were seamlessly installed during the vessel’s construction at Holland Shipyards.
The foundations were integrated into the ship’s structure, and pre-laid wiring ensured a clean and efficient setup. Gilbert de Bock highlighted the collaboration: “The shipyard and Econowind handled the installation professionally, ensuring that the VentoFoils became an integral part of the vessel without disrupting its overall design.” This thorough preparation ensured the ship was ready for optimal performance from day one.

Benefits and
results
The integration of VentoFoils has delivered tangible benefits for De Bock Maritiem’s new vessel. The ship now achieves speeds of 0.5 to 1 knot faster, resulting in fuel savings exceeding 10%.
These improvements not only reduce operational costs but also significantly lower the vessel’s carbon footprint. The system’s user-friendly interface has been well-received by the crew, and its contribution to the ship’s overall efficiency aligns with the company’s commitment to sustainability. Additionally, Gilbert de Bock emphasizes the smooth communication with Econowind, ensuring ongoing support and collaboration to maximize the system’s performance and potential.
