Wärtsilä in the Nᴇᴛʜᴇʀʟᴀɴᴅs
Huge ship propellers are being produced in Wärtsilä’s plant. Wärtsilä began operating in the Nᴇᴛʜᴇʀʟᴀɴᴅs in 1827. Since then, Wärtsilä in the Nᴇᴛʜᴇʀʟᴀɴᴅs has undergone a number of name changes and acquisitions that have brought the company to where it is now. The merger of the Dutch machine and railway equipment works and Stork in 1954 led to the Finnish Wärtsilä and Stork Werkspoor B.V. being acquired in 1989, marking the company’s entry into the Benelux. In Fɪɴʟᴀɴᴅ, the Wärtsilä corporation was founded in 1834. Worldwide sales and services are provided by Wärtsilä in the Nᴇᴛʜᴇʀʟᴀɴᴅs for the marine and dispersed power industries.

Our seven locations in Drunen, Harlingen, Kampen, Kruiningen, Schiedam, and Zwolle, employ about 900 people. Wärtsilä offers ship owners a variety of supplies and nautical services under one roof. From propellers to complete engine propulsion systems, they offer it all. For all maintenance and repair tasks, big or small, Wärtsilä in the Nᴇᴛʜᴇʀʟᴀɴᴅs offers internal knowledge. They provide service packages that go well beyond straightforward diesel engine and propulsion system maintenance and repair.

Propellers with the hub and blades cast as a single unit are known as monobloc fixed pitch propellers. It is possible to manufacture Wärtsilä FP propellers with any number and size of blades needed. The FP propeller ensures optimal efficiency with the least amount of noise and vibration possible thanks to custom designs built with the most recent technology. Excellent casting, machining, and fatigue qualities are offered by the CunialR material employed. The simplicity of reparability is an additional benefit. When maximum efficiency, dependability, and robustness are needed, a fixed-pitch propeller is an option. For ocean-going ships, fixed pitch propellers are typically used.

The hull of a ship has unique properties. The propeller needs to be ideally matched with the engine and hull for the boat to operate at its best overall efficiency. Propeller designs are always customized for a particular use, and for this contemporary design, a highly sᴋɪʟʟed hydrodynamic design team used tools. The hydrodynamic engineers at Wärtsilä are also experts in high-end Fixed Pitch Propeller designs for more sophisticated uses, such as Common rules for underwater radiated noise levels apply to these vessels.

Wärtsilä Fixed Pitch Propellers can be fitted with either the EnergoProFin propeller cap, which saves fuel or the Energopac solution, which improves maneuverability and propulsion. A High-Performance Nozzle can be fitted when the propeller is substantially laden. By being able to carefully examine both the performance of the propeller and the interplay between the propeller and hull, OPTI Design achieves even larger fuel savings.
