We have three alternatives for upgrading Brunvoll control systems:
Propulsion Thruster Control (PTC) level 1
This is where we replace obsolete physical components in an older control system with a conversion kit. No new functionality added.
PTC level 2
At level 2, we replace obsolete physical components, upgrade some of the system’s functionality, and upgrade the control system’s graphical user interface.
PTC level 3
This is where we replace an entire existing control system with a brand-new system with our latest technology, such as replacing a BruCon 3 system with a BruCon 5 system. We can do a retrofit project like this to any known control system.
Most of our projects are PTC level 1, as this is the most cost-effective, time-efficient, and non-intrusive alternative. But whatever level is chosen for the upgrade, upgrading a ship’s control system is a smart and sustainable choice. Unlike some competitors who replace entire systems on a fixed cycle, Brunvoll focuses on upgrading only the components that are no longer available on the market. This approach extends the operational life of ships while ensuring safety and efficiency—without forcing customers to replace functional parts that could outlast the vessel itself. By minimising unnecessary production, shipping, and waste, we help reduce both environmental impact and costs.
In December 2024, a team from Brunvoll travelled to Ølensvåg, near Haugesund, Norway, to carry out a significant retrofit on the MS Stril Mariner. Their mission was to replace a competitor’s old control system with a state-of-the-art Brunvoll solution. This project marked a milestone for Brunvoll, as it was the first time we delivered and installed the BruCon DP2 dynamic positioning system alongside the BruCon PTC and BruCon JS (joystick)—a full suite of advanced control technologies working seamlessly together.
The installation was successful, demonstrating our ability to efficiently execute complex ship retrofits with minimal downtime. The team worked with precision, ensuring the smooth integration of the new systems, from installation to rigorous technical testing and sea trials. The members who remained onboard the longest spent 20 days ensuring that every detail met our high standards. Their dedication and expertise reinforced Brunvoll’s reputation for delivering high-quality, future-ready solutions to the maritime industry.
“At Brunvoll, we believe in smart, sustainable upgrades—extending a vessel’s life without unnecessary waste. Our first DP2 retrofit on Stril Mar was a breakthrough success, leading the same customer to return for even larger-scale upgrades on Stril Mariner and Stril Mermaid, covering the entire maneuvering control system on the bridge. This success has sparked industry-wide recognition, with more operators choosing Brunvoll for advanced DP retrofits. Whether it’s a targeted component swap or a full-system upgrade, we deliver cutting-edge solutions with minimal disruption and maximum value for our customers and the environment, says Brunvoll’s Sales Manager Retrofit, Jim Varmedal.
