Controlling a Hydraulic Motion Compensated Gangway to Improve Access to Offshore Wind Turbines
Author: Andrew Clegg, Industrial Systems and Control Ltd.
Challenge:Creating a system to safely transfer personnel and equipment to and from offshore wind turbines in rolling seas and bad weather.
Solution:Using NI LabVIEW and NI CompactRIO to develop a movable gangway with an algorithm that computes the inverse kinematics of the gangway tip using measured boat motions to provide the required hydraulic cylinder lengths to maintain its position.
