Definitions
- the present invention relates generally to system for transporting objects to ocean structures.
- Known boarding solutions are for example hanging transport baskets, wave compensated gangways or cranes mounted on the boat transporting the personnel or equipment to the ocean structure.
- boat lifts for use with ocean structures including one or more mount components for attaching to side regions of a boat.
- One or more mechanisms are coupling between the one or more mount components and the structure for operatively lifting up or down the mount components relative to the structure.
- Such boat lift is known from GB2479742 A.
- a drawback with this systems is that the mechanisms, in the form of upright members, are welded or otherwise affixed to the ocean structure by a plurality of connection points between the upright members and the structure forming a rigid connection.
- a further drawback with such system is that it comprises many components which makes it expensive both to manufacture, as well as install and/or replace on the ocean structure.
- An object of the present invention is to provide a system for transporting objects to ocean structures which prevents personal injuries and reduces the risk of damage to the boat/equipment transported to the structure or the structure itself.
- a further object of the present invention is to provide a system for transporting objects to ocean structures which is stable yet less susceptible to bending forces.
- the bending forces may cause damage to the structure due to wear as a result of prolonged use, which in turn increases the risk for operators or crew members.
- a further object of the present invention is to provide a system for transporting objects to offshore structures which are cost effective to manufacture and install as well as replace.
- the invention provide a system for transporting object from a sea level position to an elevated position on a structure, wherein the sea level position is movable in relation to the elevated position.
- the system comprises; an elongated guide device configured to be arranged to the structure in one end and to extend below the sea level with a second end, an attachment device configured to be arranged on said object and for attaching said object to the elongated guide device, wherein the attachment device is configured to allow a relative movement between the attachment device and the elongated guide device along a first direction parallel to the extension direction of the guide device, and to restrict movement along a direction perpendicular to the first direction, a lifting device configured to transport the object from the sea level position to the elevated position ,
- the system is characterized in that a weight is arranged to the second end of the guide device below the sea level for stabilizing the guide device, wherein the second end is a free end and the weight is a free weight.
- the mass of the weight, the position of the weight and second end of the guide device sufficiently submerged below the sea level provides a stable guide device adapted to be used for lifting heavy objects, at the same time as it does not have to take up as high bending forces.
- the attachment device allow a movement along one first direction and restrict movement in a direction essentially
- the guide device has a free end with a weight for stabilizing the device, the guide device is able to pivot around its attachment point to the structure and hence move slightly relative the structure.
- the guide device withstands less bending forces on the respective parts than the previously known transport and boarding structures with a fixed guide member.
- such a system is not as susceptible to wear, will have a longer life span and require less service than the previous known solutions.
- the attachment device is configured for guiding the object from the sea level position to the elevated position along the elongated guide device when transported by the lifting device.
- the weight is arranged to the second end of the guide device at a position at least 5m below sea level, preferably at least 10m below sea level, whereby the guide device is unaffected by motions of the sea.
- the transporting procedure is simplified since the guide device is kept straight and stretched and stay unaffected of rough seas.
- the distance below sea level depend on the conditions present at the site where the structure is located.
- the weight shall be arranged at a depth unaffected by waves and sea current but shall hang free and not be attached to or rest on the bottom of the sea.
- the guide device comprises two parallel arranged guide wires having a distance from each other.
- Said guide wires are in one embodiment made of steel.
- Using two parallel arranged guide wires enables two attachment points to the object to be transported. Thus, it enables hoisting of the object without the object rotating and swinging. It is also easier to keep the object horizontal during lifting.
- the distance between the guide wires is kept constant by a beam extending between the guide wires or wherein the weight is made in one piece and extend between the guide wires. [0020] A constant distance between the guide wires simplifies the attachment procedure when the object is docked to the guide device.
- the attachment device comprises a first and a second attachment device part arranged to grip the respective guide wires.
- the attachment device parts may for example be placed on opposite sides of a stern or stem if the object is a boat or vessel. If more than one object is to be attached to the guide device at the same time, for example a boat and a container where only the container is to be lifted, it is preferred that the respective attachment device parts are arranged at the respective object so that it is possible to attach the objects on different horizontal levels.
- the weight comprises two separate blocks connected by a beam. According to one embodiment, the weight has a mass of 3- 10 tons.
- a weight having this specific mass is complicated to transport out to the structure at sea. It is therefore an advantage if the weight can be made or assembled at the structure. A weight comprising several parts is easier to handle and transport.
- the weight of the mass is dependent on the type and weight of the object to be transported. It may also be chosen to be above a certain mass so that it stays essentially unaffected by motions of the sea.
- the structure comprises beams or davits extending from the structure, wherein the first end of the guide device is
