Brunvoll - Experts & Thought Leaders

Brunvoll has secured another contract with Myklebust Shipyard for the delivery of a comprehensive thruster package. This confirms the option for an additional vessel for REM Offshore, originally announced in May of this year. Like the previous contract, this agreement also includes an option for a third additional vessel. Brunvoll’s thruster package Brunvoll’s thruster package consists of two propulsion azimuth thrusters and a tunnel thruster Brunvoll’s thruster package consists of two propulsion azimuth thrusters, two retractable azimuth thrusters, and a tunnel thruster. This configuration is the same as the previous vessel announced in May, except that this vessel with be equipped with a slightly larger tunnel thruster. The thruster package does also feature Brunvoll’s Condition Monitoring system, BruCon CMS, for enhanced operational efficiency and decision support. Energy efficiency of vessels "We have implemented several measures to enhance the energy efficiency of these vessels," says Kristian Stavset, Head of Projects at REM Offshore AS, adding "For propulsion, we selected two retractable azimuth thrusters to improve station-keeping efficiency. Additionally, we installed a larger tunnel thruster specifically for this vessel to reduce noise and vibration, ensuring greater comfort and welfare for the crew onboard." Kristian Stavset adds, "This project would not have been possible without exceptional collaboration between multiple companies. We are immensely proud to have brought together so many suppliers from our local maritime cluster to bring this project to life." Goal of net-zero emissions Skipsteknisk and REM have emphasised low energy consumption and emissions when developing the vessel The vessel named MS “REM Ocean” is designed by Skipsteknisk and shares the same platform as the previous vessel, ST-245. Although the previous vessel is an Energy Subsea Construction Vessel (ESCV), will this vessel be equipped for Inspection, Maintenance, and Repair (IMR) within the offshore energy industry. Skipsteknisk and REM have emphasised low energy consumption and emissions when developing the vessel. This has resulted in a vessel that uses only half of the energy compared to other equivalent vessels of the same tonnage, with the goal of net-zero emissions. This will be achieved through a combination of different measures like; dual-fuel engines running on methanol, battery packs, lifting-equipment with energy recovery, and a highly efficient propulsion system from Brunvoll. Brunvoll’s traditional azimuth thrusters The vessel will, after commissioning, enter operation on a long-term contract with DeepOcean, providing subsea inspection, maintenance, and repair services for Equinor. One of the retractable azimuth thrusters is a newly developed and more compact version of Brunvoll’s traditional azimuth combi thrusters, where the thruster functions as a tunnel thruster in the retracted position. New combi thruster design The new combi thruster design has a lower building height using a deal for lowering and retracting The new combi thruster design has a significantly lower building height using a similar arrangement for lowering and retracting as used for the non-combi units, and offers increased efficiency in the retracted position. This statement is from the announcement of the first vessel back in May, but still as relevant now.  Low energy consumption and emissions Bernt Rune Riksfjord, VP Sales at Brunvoll AS, said, "Local owner, local yard, local designer, and local propulsion supplier is a testimonial for what the surrounding maritime industry is capable of when we work together. Kudos to REM for trusting local expertise and supporting the local value chain, to build this cutting edge vessel." He adds, "This type of multipurpose vessels is something we have a great belief in, and the low energy consumption and emissions will make it very attractive in any market."

Brunvoll is pleased to announce its partnership with Torghatten Nord in the construction of a new hybrid ferry, set to operate between Svolvær and Skutvik in Lofoten, Norway. Scheduled for delivery in 2026, the ferry will improve both capacity and sustainability on this key route. “Our goal is to build a hybrid vessel that operates electrically over shorter distances and in hybrid mode over longer routes, contributing to lower emissions across our operations,” says Eirik Olsen, Operational Director at Torghatten Nord. Brunvoll and Torghatten Nord partner on new hybrid vessel The 73.3-metre long vessel, with a breadth of 14.3 metres, will accommodate 50 cars and 199 passengers. Equipped with a 3600 kWh battery capacity, the ferry will operate on electric power between Svolvær and Skrova, and in hybrid mode during the summer to Skutvik, significantly reducing NOx and CO2 emissions. Brunvoll to supply essential systems for the ferry Brunvoll will supply essential systems for the ferry, including two pulling azimuth thrusters Brunvoll will supply essential systems for the ferry, including two pulling azimuth thrusters, an Auto-Crossing system, a remote condition monitoring system, and a bridge-to-blade control system (BruCon PTC), ensuring efficient and reliable operation. The ferry will be constructed by Western Baltija Shipbuilding, located in Lithuania, and is designed by The Norwegian Ship Design Company. The vessel is scheduled for delivery in 2026. Brunvoll and Torghatten Nord partnership “We are proud to support this project with our advanced propulsion and autonomy solutions,” says Nils Arne Øksenvåg, Sales Manager at Brunvoll. Brunvoll's Auto-Crossing system will be installed, featuring a bridge control panel. The BruCon Auto-Crossing system keeps the route and speed, steady and efficiently, with smooth accelerations.

Brunvoll has signed a contract with Aas Mek Verksted for the delivery of a propulsion, manoeuvring, and positioning system for Njord Aquashipping’s new live fish carriers. The delivery is for two vessels, with one additional vessel as an option. Brunvoll’s delivery for each of the two vessels consists of: Two ducted azimuth propulsion thrusters, a tunnel thruster, Brunvoll’s Propulsion and Thruster Control system (BruCon PTC), and Brunvoll’s Dynamic Positioning system with class 0 (BruCon DP0). Requirements for a DP system The class 0 DP system is ideal for vessels like live fish carriers and aquaculture service vessels "This is an exciting step for Njord Aquashipping AS. We are very pleased to build these vessels in Norway and to work with high-quality Norwegian suppliers like Brunvoll. We look forward to strengthening our fleet with these state-of-the-art vessels," says Tomas Okstad, CEO of Njord Aquashipping AS. The class 0 DP system is ideal for vessels like live fish carriers and aquaculture service vessels, where there are no class requirements for a DP system. The DP system helps the crew of the vessel to manoeuvre and hold the vessel's position during operations around the fish farm, increasing the safety of both the fish and crew, and at the same time reducing energy consumption. Azimuth propulsion thrusters The ducted azimuth propulsion thrusters are of the AUP84 type, which is a newly developed size to suit a wider range of vessels. The azimuth thrusters will have a propeller diametre of 2.1 metres and a power output of 1500 kW, each. The vessels will become Aas Mek’s new build no. 217 and 218. The vessels have a length over all of 89 metres and a loading capacity of 4.700 tons.
