Knuckle boom crane, for offshore application

A knuckle boom crane suitable for offshore application, which knuckle boom crane comprises:

• a crane house,
• a knuckle boom, carried by said crane house,
• operating means for operating said crane house and said knuckle boom, and
• control means, for piloting said operating means,
• said knuckle boom comprising a main boom and a jib, in series, said main boom and said jib each including an upstream end and a downstream end,
• said crane house comprising knuckle means for defining a slewing motion of the knuckle boom about a slewing axis,
• said crane house and said upstream end of the main boom cooperate through upstream knuckle means to define a luffing motion of said main boom about an upstream knuckle axis,
• said downstream end of the main boom and said upstream end of the jib cooperate through downstream knuckle means to define a folding motion of said jib about a downstream knuckle axis,
• said operating means including:
• at least one slewing actuator, for generating the slewing motion of said knuckle boom,
• at least one first linear actuator, for generating said luffing motion of said main boom, and
• at least one second linear actuator, for generating said folding motion of said jib,
• and said control means include an active compensation module that is designed to pilot said operating means, taking into account data coming from a motion reference unit, in such a way as to stabilize the downstream end of the jib.
