Abstract: The present invention relates to a unit (1) for offshore application, comprising a deck (2) equipped with a crane (3) with an articulated boom (4). which crane (3) comprises: a support structure (5), secured to said deck (2), and an articulated boom (4), carried by said support structure (5). The articulated boom (4) comprises a main boom (41) and a terminal boom (42), in series, which terminal boom (42) has a head (422) at the opposite side of said support structure (5). This deck (2) is equipped with a cradle (10), at a distance from the support structure (5), which comprises a receiving portion (101) on which a head (422) of said terminal boom (42) is intended to rest in said rest position.

Abstract: The present invention relates to a gangway system (1) for an offshore service vessel (N), suitable for the transfer of personnel between said service vessel and an offshore structure(S), in wave motion conditions. The gangway system (1) comprises a telescopic corridor (7), which has an upstream section (71) and a downstream section (72), movable in translation relative to said upstream section (71). The gangway system (1) further comprises means for maneuvering said gangway (5), in particular yaw maneuvering means (11), pitch maneuvering means (12) and translation maneuvering means (13). The maneuvering means (10) cooperate with control means (15) so as to stabilize the downstream end (722) of the gangway (5) at, preferably resting on, said offshore structure(S).

Abstract: Disclosed is an active compensation system, intended to compensate at least partially for the effect of an undulating movement on a load, advantageously in a vertical direction, preferably for the active compensation of the swell. The active compensation system includes: —an electrical supply electrically connected to electrical storage unit; —electrical energy dissipating unit; and —a controller for discharging the electrical storage unit during a first phase of the undulating movement, to participate in the electrical supply of the electrical motor in addition to the power supply, and to recharge the electrical storage via the electrical supply during a second phase of the undulating movement.

Abstract: Disclosed is a crane, in particular for offshore application. The crane includes a bearing the assembly between a pedestal and a carrier frame. The bearings are distributed over the height of the support structure and include upper bearing, which include a radial contact rolling bearing including rolling elements and a smooth cylindrical raceway, coaxial to the axis of rotation. The radial contact rolling bearing allows a longitudinal translational degree of freedom of the rolling elements over the height of the cylindrical raceway.

Abstract: Disclosed is a knuckle boom crane, for offshore application, the knuckle boom crane including a crane house, a knuckle boom carried by the crane house, a component for operating the crane house and the knuckle boom, and a controller for piloting the operating component. The controller include a active compensation module that is designed to pilot the operating means, taking into account data coming from a motion reference unit, in such a way as to stabilize a downstream end of the jib, advantageously in a horizontal plane and/or a vertical position, still preferably in all directions.
