Dynamic positioning is a crucial technology that allows the vessel to maintain her position and heading in varying environmental conditions by using own propellers and thrusters.
Vessels with accurate sensors and powerful propulsion may achieve centimeters accuracy of positioning even under strong environments.
Navis is a leading expert in this field, with over 20 years of experience and a portfolio of more than 800 DP vessels operating worldwide.
Navis DP control systems are installed on a wide range of vessel types, from newbuilds to retrofits, including:
– Anchor handling vessels (AHV, AHTS)
– Platform supply vessels (PSV)
– Offshore supply vessels (OSV)
– Fast support interventional vessel (FSIV)
– Fast crew boats (FSV)
– Service operation vessels (SOV)
– Multicats
– Drilling vessels
– Jack-up vessels
– Pipelay vessels
– Cable layrepair vessels

Overview of the DP5000 system
Advanced ergonomic workstation design
The DP5000 is the next generation Navis Dynamic Positioning System, combining the best of the legacy system, the Navis IVCS series, with the latest advances in technology and design, designed to meet the needs of experienced Dynamic Positioning System operators, recent changes in classification society requirements and market trends.
User interface design
The DP50000 user interface has been developed in close collaboration with dynamic positioning system operators and ergonomics experts. The priorities were simplicity, consistency, unambiguous presentation of information and quick access to all functions. The design of the new user interface does not use Windows system controls, instead it uses instrument-like controls.
A high-quality, marine-certified touch screen and next-generation control panel with a high-resolution color display and few control buttons provide a user-friendly and intuitive user interface.
Voice alert features for alarm messages help you maintain a high level of awareness in any situation.
Diagram for providing the necessary stops
The diagram for providing the necessary stops is a unique development of our company. In real time, it allows you to have an idea of what stops can be reached by the ship’s actuators based on their configuration, power and achievable angular momentum.
Since each stop can be considered as a vector, the diagram is a bounded set on the plane, where each point corresponds to a certain combination of stops achievable under given conditions.
This set of stops depends on the amount of required angular momentum. In case of any changes in parameters or conditions, the diagram is automatically updated.
If the given force vector goes beyond the boundaries, and the real force vector is on the border of the diagram, the system seeks to minimize the difference between these vectors.
System health monitoring
The DP5000 system constantly monitors information from the ship’s power plant management system, such as: the load on each generator and actuator, their connection to the power bus, and the connection of the power busses to each other.
In the event of a propulsion system shutdown, the DP5000 automatically calculates new thrust and angular momentum requirements based on each generator’s power generation limits and distributes the thrusts to the ship’s actuators, minimizing the effect of a drop in propulsion power on keeping the vessel at point/on course.
Power system monitoring and emergency shutdown prevention
The system constantly monitors its components (programmable logic controllers, computers, buses, etc.), sensors, propulsion system, generators and power networks in real time. Relevant information is also available to the operator in the form of text messages, or in the form of a simple and clear diagram displayed on the screen upon request.
The diagram uses different colors to display the state of the components and the relationships between them. In the event that a component or connection changes its state (i.e. becomes active or inactive or fails), the color of the rendered component also changes.
Оsitioning relative to multiple targets
The Target Following mode allows you to keep your boat on course or position your boat within specified limits relative to a selected target.
The DP5000 system provides both a single target tracking mode and a multi-target mode.
