Kongsberg Maritime UT design vessel conversions Cargo conversions Design options available range from simply rebuilding the tanks to accommodate a different type of cargo, through moderate and reversible adaptation, to total cargo area conversion. Our conversions are designed with cargo handling systems and arrangements that ensure efficient and safe loading and unloading of cargo. There is a high focus on low acceleration to reduce wave slamming, improve vessel performance in a seaway, minimise potential cargo damage and provide optimal living conditions for the crew. Focused on safety Safety is at the forefront of everything we do and our customers can be assured that all of our conversion designs include the latest advances in safety improvement. As part of the conversion we are able to install equipment health monitoring solutions that support safer asset operation.

System conversions Cost saving, improved fuel efficiency and reduced environmental footprint Power and propulsion system re-powering or conversion can assist in achieving your operational targets to reduce fuel consumption and meet environmental requirements. It can also provide improved operational flexibility and increase the power and capability of your vessels. Hybrid propulsion solutions Our hybrid shaft generator (HSG) system is an advanced power electric system which supplies fixed frequency power to the switchboard even when the engine RPM varies. This enables much more flexible use of engine and propeller speed variations. It means that both propeller and engine efficiencies can be maximised by running them at their design points. Doing so also helps to reduce exhaust CO2 and NOx emissions. The HSG system provides efficient operation without compromising functionality over the vessel’s entire operating profile. As a dedicated system integrator, we ensure that all proprietary equipment functions coherently and safely. Vessel conversions Moving into a new market Whether your vessel is a Kongsberg Maritime design or not we are able to deliver innovative full concept packages to meet your requirements for value, functionality and performance. All vessels are individually re-designed for their new tasks, based on operational demands along with classification and overall vessel performance requirements. Close cooperation from the start of a project ensures that consideration is given to all aspects and that our customers’ valuable experiences become a vital part of the development of the design. Customers can benefit from customised tank solutions, deck design and cargo facilities.

High Precision Applications Primed for excellence, the MRU 5 is the optimal sensor for various motion compensatory functions used in multi-beam echo sounders, offshore cranes, hydroacoustic positioning systems, and dynamic motion monitoring on offshore structures. Its unparalleled roll and pitch accuracy of 0.02° RMS within a ±5° amplitude is proven and documented, ensuring reliable performance on any surface vessel or subsea vehicle. Advanced Sensor Technology and Configurability Integrating three top-tier accelerometers with three premier Kongsberg Seatex developed MEMS gyros of MRG type, the MRU 5 exhibits low noise characteristics alongside exceptional bias stability and gain accuracy. This high reliability is attributed to the use of solid-state sensors, which circumvents any mechanical wear. Adding to its feature set, this unit comes with specialized Windows-based configuration and data presentation software, which allows for the precise definition of vector arms to the center of gravity and two individually configurable monitoring points. Enhanced Data Output and Complementary Algorithms The MRU 5 is proficient in the output of critical motion-related variables, such as roll, pitch, and yaw angles as well as angular rate vectors across various adjustable frames. Furthermore, with the employment of the cutting-edge PFreeHeave algorithm, it overcomes the perils of long swell conditions and is ideal for applications that can utilize a delayed heave signal, commonly observed in seabed mapping operations. External speed and heading inputs are also accepted to augment the accuracy of heave, roll, and pitch under dynamic conditions.

The MRU 5 represents the pinnacle of marine motion sensing technology – embodying a specially designed fifth-generation device that excels in delivering high precision motion measurements within marine applications. It stands out in its ability to offer highly accurate roll, pitch, and heave measurements for the most demanding users.

Precision and Reliability The MRU 5+ provides documented roll and pitch accuracy of 0.008° and angle noise less than 0.002°. Every unit is delivered with an individual calibration certificate documenting this accuracy. This is made possible by use of accurate inertial sensors including three rate gyros and linear accelerometers of excellent tactical navigation grade performance. Very high reliability is achieved by using solid-state sensors with no moving parts and the proven MRU electrical and mechanical construction. Advanced Motion Sensing Technology The PFreeHeave algorithm uses past measurements to output a correct and phase-free heave from MRU 5+. It has an advantage in long swell conditions and for applications that can utilize a heave signal that is delayed some minutes, typical for seabed mapping applications. Additionally, a new MEMS based gyro is developed by Kongsberg Seatex AS called MRG5 (Mru Rate Gyro) model 5. The MRG5 is optimized for use in high-end applications. The MRU rate gyro combines very low noise, excellent bias stability and outstanding gain accuracy and is the best MEMS rate gyro available for maritime applications. Ease of Integration and Application Flexibility Interfacing the MRU 5+ to various sonar systems is made easy by including data protocols for the most commonly used multibeam echo sounder systems in the software. Using the configuration cable and the Windows version of the configuration software, MRC+, a series of simple menu prompts allow the user to choose the optimum configuration for his application.

The HiPAP 352P is a portable system designed for tracking

ROVs, tow fish, divers, and other subsea objects at several

thousand metres range. Operating in SSBL mode, it measures

the distance and direction to subsea transponders and computes

a 3D position in either local or geographical coordinates.

Featuring buit -in motion sensors, the HiPAP 352P compensates

for the vessel’s roll and pitch movements, enhancingpositioning

accuracy. Models such as HiPAP 352P-H and HiPAP 352P-5

incorporate MRU-H and MRU-5 motion sensors, respectively.

These models require no calibration for roll and pitch alignments

but do need to be calibrated in alignmentwith the vessel’s gyro compass.

Meanwhile, the HiPAP 352P-MGC combines a motion sensor and a gyro

compass,completely eliminating the need for roll, pitch, and heading

alignments calibration.
