Below is a multiple question test to check your knowledge on DP systems. 7.1. General Questions on DP What is the difference between ‘DP current’ and real current? ‘DP current’ is the current value that the DP system shows on the DP screen. It is equal to the total thruster force minus the Wind Force. DP current = Thruster force …

Dynamic Positioning Systems, Principles, Design and Applications
What is dynamic positioning (DP)?
Dynamic Positioning (DP) is a vessel capability provided via an integration of a variety of individual systems and functions*. A computer control system automatically maintains a vessel’s position and heading by using her own propellers and thrusters.
What is dynamic positioning?
Introduction to Dynamic Positioning 1.1. Dynamic Positioning Systems For many offshore operations it is necessary to keep a vessel at a fix position and heading. Traditionally this has been done using an anchor spread. Nowadays, Dynamic Positioning (DP) systems are replacing anchors.
What is a positioning system (DP)?
The positioning system, usually a GPS, monitors the position of the vessel. When the vessel moves off the intended position the DP computer will calculate the required thrust which will then be applying by the thrusters in order to maintain the position of the vessel. 1.2. The use of DP systems
What is a dynamic positioning operator (DPO)?
Dynamic positioning systems require specially trained and skilled personnel to handle the systems at sea. The person who mans the entire system and ensures the smooth functioning of a DP vessel is known as a DP operator. The dynamic positioning operator (DPO) needs to be trained appropriately before taking up the reins of the demanding profession.
What are the applications of Dynamic Positioning System in maritime industry?
As the applications of Dynamic Positioning System increase in the maritime industry, different types of ships are now being fitted with DP systems to improve control and handling over vessels at sea.
How do schools use the dynamic placement test?
Schools, universities and companies use the test for a variety of purposes, including testing incoming students pre- or post-arrival, assigning learners to specific courses, and filtering job applicants based on their English. Find out more about how these institutions (and others) use the Dynamic Placement Test.
What is the importance of capability curve in DP operation?
The capability curves allows to find the limiting wind speed for safe DP operation of the vessel.
To prepare a DP capability curve for a certain vessel wind, current and waves are normally taken to act in the same direction. What is consequence analysis DP? Consequence analysis is used to verify the safety of a DP operation. It is used to check whether there is sufficient running power and thruster capacity available to retain sufficient …
How does the system track the position of the object?
Once the initial position is inputed to the system it able to track the any movements and determine the relative position from a start point. The systems is accurate for a limited time period.
What is position tracking and how does it work?
Position tracking systems are also adept for mapping rooms, facilities, and transit routes for different electronics. Some companies, like Accuware, use a hybridized system for tracking and sensing. This mapping-and-positioning method employs a camera as a sensor. The camera also enables continuous tracking in a 3D space.
How does an optical tracking system work?
By using a model of this configuration of each object, the optical tracking system is able to distinguish between objects and determine the 3D position and orientation of each object. Optical tracking has proved to be a valuable alternative to tracking systems based on other technologies, such as magnetic, acoustic, gyroscopic and mechanical.
What is a tracking system?
A tracking system, also known as a locating system, is used for the observing of persons or objects on the move and supplying a timely ordered sequence of location data for further processing. There are myriads of tracking systems.
How do the tags track the position of the object?
The tags triangulate their 3D position using the anchors placed around the perimeter. A wireless technology called Ultra Wideband has enabled the position tracking to reach a precision of under 100 mm. By using sensor fusion and high speed algorithms, the tracking precision can reach 5 mm level with update speeds of 200 Hz or 5 ms latency .
