1. A hydrocarbon transfer system, comprising: a first structure with a first direction and a transverse direction, the first structure having a frame carrying a vertical arm and a fluid connecting member at an end of the vertical arm for connection with a second structure moored alongside the first structure,wherein the connecting member comprises a winch and first guiding means for engaging with a second guiding means on the second structure via a wire connected to the winch at a first end of the wire and to the second structure at a second end of the wire, and a tension device for moving the vertical arm away from the second structure for tensioning the wire,wherein the frame is rotatable around a vertical axis, and comprises a rotatable support frame part extending upwardly from a deck level of the first structure,wherein the rotatable frame part has a transverse arm connected thereto, the transverse arm including a transverse fluid transfer duct, and a secondary arm extending downwardly from a movable joint on the transverse arm so that the secondary arm is pivotable about a first axis extending substantially in the first direction, the secondary arm including a secondary fluid duct,wherein the transverse arm is pivotably connected to the rotatable frame to pivot about a second axis through the rotatable frame, and a counterweight is connected at an end of the transverse arm, andwherein the secondary arm comprises a first actuator to pivot the vertical arm about the first axis, and the transverse arm comprises a second actuator to pivot the transverse arm about the second axis. 2. The hydrocarbon transfer system according to claim 1, wherein the secondary arm comprises a rigid arm connected to the transverse arm via a swivel. 3. The hydrocarbon transfer system according to claim 2, wherein the rigid arm comprises a secondary counter weight connected via a pivot element to an end of the rigid arm and located proximate to the vertical axis. 4. The hydrocarbon transfer system according to claim 1, wherein the secondary arm comprises a flexible hose. 5. An apparatus for connecting a fluid transfer duct to a floating vessel, comprising: a base part extending upwardly from a first structure;a first substantially horizontal arm with a counterbalance system, the first arm being pivotably connected to an upper end of the base part;a second substantially vertical arm supported by the first arm;a pivoting force element between the upper end of the base part and the first arm for controlling an inclination of the first arm relative to the base part; anda first coupling part which is pivotably connected to a lower end of the second arm so that the first coupling part can pivot around three axes, the first coupling part having a horizontally placed first flange for making a vertical fluid connection with a horizontally placed second flange of a second coupling part fixed on a vessel for the transfer of fluids,the first coupling part further provided with a pull-in line winch for a pull-in line, and a first downwardly orientated guide means configured to cooperate with a second upwardly orientated guide means proximate to the second coupling part such that when the second arm is lowered towards the vessel during a connection procedure, the final displacement between the first and second flange is in a vertical direction. 6. The apparatus according to claim 5, wherein the apparatus comprises hydraulic control lines along the arms to control a heading of the first coupling part. 7. The apparatus according to claim 5, wherein the first guide means and the pull-in winch are placed on opposite sides of a vertical axis of the first coupling part such that the first coupling part is balanced in a horizontal plane. 8. The apparatus according to claim 5, wherein the first arm is placed plus or minus 10 degrees from the horizontal, and the second arm is plus or minus 10 degrees from the vertical during connection of the first coupling part with the second coupling part. 9. The apparatus according to claim 5, further comprising: a system for manipulating an orientation of the first coupling part during connection of the first coupling part with the second coupling part so that the first coupling part is always more or less perpendicular to the longitudinal axis of the vessel to align the first and second guide means and the first and second flanges. 10. The apparatus according to claim 9, wherein said manipulating system comprises a hydraulic system. 11. The apparatus according to claim 10, wherein the system for manipulating the orientation of the first coupling part consists of a hydraulic system which is driven by an offset of the first or second arm. 12. The apparatus according to claim 5, further comprising: a pivoting force element that is re-adjustable for an additional weight of ice building up on the first and second arm during transfer of LNG. 13. The apparatus according to claim 5, wherein the first arm is displaceable relative to the base part in a direction transverse to the vessel. 14. The apparatus according to claim 5, wherein the first structure is an offshore placed floating unit moored to the seabed. 15. The apparatus according to claim 6, wherein the first guide means and the pull-in winch are placed on opposite sides of the vertical axis of the first coupling part so that the first coupling part is balanced in a horizontal plane. 16. A method of connecting a fluid transfer apparatus to a vessel, the apparatus comprised of a base part extending upwardly from a first structure, a first arm with a counterbalance system, the first arm being pivotally connected to an upper end of the base part, a second arm pivotally supported by the first arm, a pivoting force element between the upper end of the base part and the first arm for controlling an inclination of the first arm relative to the base part, a first coupling part pivotally connected to a lower end of the second arm so that the first coupling part can pivot about three axes, the first coupling part having a horizontally placed first flange for making a fluid connection with a horizontally placed second flange of a second coupling part fixed on a vessel for the transfer of fluids, the first coupling part further provided with a pull-in line winch for a pull-in line and a first downwardly orientated guide means configured to cooperate with a second upward orientated guide means proximate to the second coupling part, the method comprising the steps of: connecting the pull-in line to the second guide means and tensioning said line with the aid of the winch;generating a small upward tension force in the second arm with the aid of the pivoting force element;lowering the second arm by pulling in the pull-in line via the winch;vertically aligning the first and second flanges with the aid of the first and second guide means while pulling in the pull-in line; andlowering in a vertical direction the first flange onto the second flange and securing a fluid tight connection between the two horizontal flanges.
