Our ambitions: Brunvoll will ensure the highest quality, energy efficiency, security and environmental reliability in our products and services. We will be known for delivering products that secure little to no risk of environmental pollution or cyber security breach.

Our achievements in 2023

  • ISO27001 certification – Cyber Security
  • Contract to provide Auto-Crossing technology for new Fjord1 ferries

Quality and long-term perspectives

We have designed and manufactured maritime equipment since 1912. Our products are designed with durable and reliable operation as one of the main objectives. With proper use, service and maintenance, our thrusters and propulsion equipment will outlive the lifetime of the vessel. Utilising well-built equipment for the complete lifetime of a vessel will have a lower impact on the environment and the overall operational cost as opposed to a strategy for maintenance by replacement.

Since 1965, we have built and installed around 12 200 high quality thruster and propulsion systems in some 6 100 vessels of which the vast majority are still in daily operation.

“All thruster and propulsion systems fail from time to time. However, Brunvoll’s systems just fail more rarely than other systems. If there is a failure, Brunvoll is immediately there to remedy the issue with relevant spare parts and correct expertise.”

Energy-efficient products and services

We continuously invest considerable time and resources in developing new and more energy-efficient products. This includes novel propeller and thruster solutions, control and monitoring systems, drive systems and autonomous systems. Our R&D departments accumulated 75 000 hours in 2023, and a large proportion of our new-sales revenue is realised through the offering of products and services developed during the last five years. Many thrusters and propulsion systems already in operation are also upgraded with state-of-the-art technology which extends the lifetime of the vessels and contributes positively to energy savings and reduction in GHG emissions.

All Brunvoll thrusters and propulsion systems are delivered with the Brunvoll control system, BruCon. In-house production of both the thrusters and propulsion systems along with the control system has helped us develop robust, smart and energy efficient ways of operating a vessel with today’s technology.

Part of our business model is the aftermarket, where service and maintenance is offered on-site at yards across the globe, requiring us to travel. To reduce the carbon footprint of travel, we rely on digital tools and a global presence through local service stations in strategic areas. Today, we are represented with local service stations in 40 countries, and we have developed a Condition Monitoring System (CMS) enabling remote diagnostics and support. The CMS also allows for further condition-based maintenance instead of the traditional preventive maintenance model. 205 of our units were equipped with CMS at the end of 2023, which is an increase of 38 units from the previous year.

As the normalisation of the pandemic has made travelling easier, we see a rise in our business and service travels from 2021 to 2023. Service travel has increased because of increased revenue in this segment. Business travel was artificially low in the pandemic years, but we are continuously working on decreasing our emissions from business travel. Meetings in Microsoft Teams have replaced a lot of travel, but we have also increased both our number of employees and our total revenue. These factors also impact our emissions from travel.

Product pollution

Today, most thrusters and propulsion systems from Brunvoll are prepared to operate on Environmentally Acceptable Lubricants (EALs). Conversion into EAL operation is also available on systems in service, allowing the vessels to be VGP (Vessel General Permit) compliant without replacing their thrusters and propulsion systems.

Cyber security

As various products and functions in a vessel are more and more interconnected, cyber security is one of our top concerns. We follow the recommendations from Center of Internet Security (CIS) and National Cyber Security Center (NSM), and are now certified according to ISO 27001. No cyber security breaches were reported in 2023.
