# Self-contained transportable electric heave compensation system

## Abstract

A mobile active heave compensation system (10) provided with a first attachment device (12) allowing said mobile active heave compensation system (10) to be suspended from a load bearing device (14) and provided with a second attachment device (16) allowing said mobile active heave compensation system (10) to carry a payload (18), said mobile active heave compensation system (10) comprising: - a control unit (20), - a heave compensation part (22) comprising an electrically driven actuator (24), - a sensor arrangement (26) producing input signals for said control unit (20) to control the heave compensation part (22), - an electric power source (28) provided with supercapacitors (30), such that, in a first heave compensation phase, when the heave compensation part (22) generates energy, electric power is stored in said supercapacitors (30) and, in a second heave compensation phase, when the heave compensation part (22) requires energy, electric power stored in said supercapacitors (30) is supplied to said electrically driven actuator (24).
