A new direction for DP - 2

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...

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...

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...

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,...
