Dynamic positioning (DP) is a computer-controlled system used to maintain a vessel‘s position and heading by automatically activating propellers and thrusters to counteract the displacing effects of the external environment. Sensors provide information to the control system which incorporates a mathematical model of the vessel including information about the vessel’s dynamics, its machinery and its responses to environmental and other displacing forces. The model information together with the sensor data enables the DP system to calculate the required output for each thruster and propeller to...

The experience to redefine DP We know DP, deeply. Since the 1970’s we’ve built more than 800 systems, from joystick maneuvering and “simple” DP to multi-redundant DP and Thruster Assisted Mooring Systems (TAMS). Our technological range is coupled with front-line, hands-on expertise in all vessel types. No one is better positioned to develop the DP system you need. By applying our engineering intelligence, and understanding your maritime operations, we’ve evolved DP to the next level. The result: a new range of DP systems developed to deliver the reliability, efficiency and effectiveness you demand....

Unprecedented flexibility for effective maritime operations Putting the Operator in Control GE’s latest range of DP systems is a mariner-focused solution, enhancing situational awareness and rebalancing attention from system management to true seamanship. It delivers the following benefits: • nprecedented flexibility U for effective maritime operations. • n energy-efficient nautical system A to reduce operational costs and emissions. • fully integrated system configured A for optimum power & propulsion performance. GE’s new direction in DP control systems sets new standards of excellence in ship...

Intuitive graphic interface Easy to use – quick to learn for DP operators switching from other DP systems 26-inch touch sensitive multi-touch screen Reduced need for data processing by operator; increased focus on seamanship Configurable displays show data in clear and uncluttered form Easier and faster system navigation Operator/task specific information prioritization Improved focus on positioning the vessel rather than manipulating the control system Screen tilt angle adjustable Enables standing or seated operation Helps reduce screen reflections and glare Screen display available in different...

An energy-efficient nautical solution GE’s expertise in DP and in power and propulsion systems has prompted the development of DP capabilities which impact on fuel economy, emissions, machinery wear, and machinery maintenance (time/cost). Operational costs are reduced and overall system up time/availability may be increased. Mode Operation Energy Efficient Mode A utomatic position and heading control. Using predictive software to anticipate position variation and to limit thrust changes if the vessel is predicted to remain within the ‘soft’ operating window. the vessel is predicted to move outside...

GE as a full system integrator Positioning DP in the Big Picture At GE, we see the whole ship. That’s because we engineer and supply so much of it, from gas turbines and diesel engines to rotating machines, variable speed drives, drilling systems and automation and control. We power, propel and position the industry. As engineers with broad vision, we understand the role of the DP control system relative to the entire vessel’s operations; its integrated role in a network involving power generation and distribution equipment, propulsion and maneuvering machinery, digital controllers, electrical...
