OPERATIONS & MAINTENANCE
durability,” Bjørkedal says. He adds that both product families
are “bottom-line sustainable” due to their maintenance-free design. By eliminating the need for regular servicing and the associated downtime, they ensure continuous operation. This not only removes the necessity for service engineers to visit the vessel but also results in substantial cost savings. Consequently, the uninterrupted performance and reduced operational expenses directly enhance the financial health and efficiency of the operations.
ACCURACY IS KING The MRU and MGC form the core of Kongsberg Discovery’s Seapath platforms targeting complex hydrographic surveys and seabed mapping. The latest Kongsberg EM2042 MBES brings the miniMRU fully embedded to simplify installation and create a unified INS and multibeam system. The inertial sensor works together with state-of-the-art multi- frequency GNSS receivers and processing algorithms to provide the best possible position, velocity, attitude, time and heading data. All available GPS, GLONASS, Galileo, Beidou and QZSS satellites are used in the position solution.
The MiniMRU provides a SWaP-C of high-end inertial sensors
onboard a vessel – for navigation, cranes, DP, you name it. That is revolutionary,” says Bjørkedal. Similar to the MRU family, the MGCs
are scoped to cater for different use cases and accuracy requirements. The MGGs are built using a different gyro technology, with ring-lasers (RLG) replacing the MRUs’ MEMS- based gyros. These gyros are so sensitive they are able to detect the Earth’s rotation, enabling the MGC to calculate true north.
SIMPLIFYING NAVIGATION For vessel navigation, the stability of the MGC can be translated to less rudder usage and thus reduced fuel consumption and emissions. “This is
because fewer course adjustments are necessary, which reduces the impact of the rudder and extends the lifespan of the steering system. That also goes for high-speed vessels,” Bjørkedal says. The exceptional north-seeking
capabilities of the MGC outperform conventional gyrocompasses, and this is especially visible in high latitudes. “This capability is beneficial not only for dedicated Polar ships but will also be very relevant if northern sea routes are used amid retreating Arctic sea- ice,” Bjørkedal adds. The latest generation of MRUs
and MCGs is built on the legacy of more than 30 years of experience. “Customers report that the units just keep on working, which is a clear testament to their reliability and
CUSTOMISED TO REQUIREMENTS In summary, inertial technology is critical for robust and accurate maritime operations and all Kongsberg Discovery’s MRU/MGC solutions are uniquely flexible. “The segments we serve tend to be bespoke, so in addition to providing standalone units for integration into third- party systems, we also collaborate directly with customers to adapt the technology to their unique challenges.” Bjørkedal says.
