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).
