The following work presents modelling. simulation and results of hydraulic motor and hydraulic cylinder position measurement for a hydraulic active heave compensation system (AHC). In order to perform experimental research the authors developed a test stand. A hydraulic cylinder is used to carry out a simulation of sea waves. https://www.ngetikin.com/mega-save-NHL-Calgary-Flames-Home-Jersey-iPhone-XR-Skin-p120897-hot-value/
