Abstract
Description
- The invention relates to a heavy duty monopile fastening system for retaining a monopile of a windmill during transport, comprising a frame for supporting the monopile, which frame comprises supporting elements at a predetermined distance from each other, which distance is selected to enable the frame to receive and support the monopile.
-
EP 3 109 531 - It is a disadvantage of the known system for retaining an elongated monopile that it requires ancillary equipment like the hydraulic cylinders which makes the system relatively costly and also subject to regular maintenance in order to secure its proper operation.
- It is remarked that from
DE 41 23 430 a retaining element of plastic is known, for holding at least one pipe or cable with a bearing portion mountable on a support and a holding portion with two opposing shell parts interconnected in a lower region of these parts, which are connected on both sides of said lower portion with a resilient intermediate piece, which merges into a storage area, wherein the shell parts in their upper region are connectable to each other via engagement elements, and wherein the shell parts each have an elastic web interconnecting and attached to an inner and an outer end of the shell parts for holding pipes of different diameters. This retaining element ofDE 41 23 430 is obviously not suitable for the heavy-duty application to retain a monopile of a windmill during transportation. It therefore does not relate to the subject matter of the instant invention. - It is an object of the invention to provide a monopile fastening system of simpler and therewith cheaper design, which hardly requires maintenance, if any at all.
- It is a further object of the invention to provide a monopile fastening system which is capable of receiving and supporting monopiles in a vast range of different diameters.
- It is still a further object of the invention to provide a monopile fasting system which is equipped to be used with relatively large diameter monopiles and without damaging such monopiles that are more prone to be indented due to their disadvantageous ratio of wall thickness versus diameter.
- Still a further object of the invention is to provide a monopile fasting system which is capable to compensate the limited capacity of cranes that are used to handle monopiles of relatively large weight.
- The heavy duty monopile fastening system of the invention has the features of one or more of the appended claims.
- According to a first aspect of the invention the supporting elements are embodied as vertically straight uprising standards, wherein at least a first vertically straight uprising standard is provided with at least one pivotable and upstanding substantially straight arm having its pivot in common with the first vertically straight uprising standard, and that at least one flexible element or band is provided to connect the first vertically straight uprising standard with a second vertically straight uprising standard, wherein the at least one flexible element or band is embodied with two extremities distant from each other, and that a first extremity of the at least one flexible element or band connects to the upstanding arm at a position distant from the pivot which the arm has in common with the first vertically straight uprising standard, and that a second extremity of the at least one flexible element or band connects to the second vertically straight uprising standard.
- Since it concerns a heavy-duty system, same cannot be embodied in plastic. Usually the supporting construction of the system -except for the at least one flexible element or band- is embodied in a construction metal, preferably steel.
- The construction of the heavy duty monopile fastening system of the invention provides that it is essentially a self-adjusting system which is capable to receive and support monopiles of different diameters, without need to make much adjustments to the system. The system employs gravity in that the heavy weight of the monopile itself arranges for a close engagement of the flexible element or band against the outer circumference of the monopile which secures that the monopile is safeguarded against longitudinal motion by friction, and secured against lateral motion by the suspension between the vertically straight uprising standards.
- Although some variation is allowed it is preferable that the second extremity of the at least one flexible element or band has a point of engagement with the second vertically uprising standard at a height which is level or approximately level with a height at which the first extremity of the at least one flexible element or band connects to the upstanding arm when said arm is in an upright orientation.
- The construction with the at least one pivotable and upstanding arm having its pivot in common with the first vertically uprising standard arranges that the flexible element or band will tightly engage and to the largest possible extent against the circumference of the monopile, which is beneficial for providing the largest possible frictional contact area between the at least one flexible element or band and the monopile.
- It is further preferable that at or near the connection of the at least one flexible element or band with the upstanding arm of the first vertically uprising standard and at or near the point of engagement of the at least one flexible element or band with the second vertically uprising standard, engagement blocks are provided for engaging and resting against the monopile. These engagement blocks are preferably of rubber or caoutchouc and can provide a further frictional contact with the monopile and may prevent damage to the monopiles, such as indents in the outer surface of the monopiles.
- The functionality of the engagement blocks can be optimized by arranging that each engagement block is provided with a curved surface that approximately matches the curvature of the monopile to be supported.
- Although the basic construction of the monopile fastening system as discussed hereinabove is already capable to receive and support monopiles of different diameters, this capability can be further promoted by arranging that the flexible element or band is length-adjustable.
- In one embodiment the first standard and/or the second standard is provided with multiple connectors for the at least one flexible element or band. This feature provides an easy way when the length of the at least one flexible element or band is to be adjusted and tailored to the diameter of the monopiles to be supported.
- The capability to receive and support monopiles of different diameters can be further promoted by arranging that the first and second vertically uprising standards are movable with respect to each other.
- Particularly when the first and second vertically uprising standards are movable with respect to each other, but also in other situations, stability of the construction according to the invention can be promoted by arranging that the first and second vertically uprising standards are provided with at least one distance arm to secure a predetermined distance between the first and second vertically uprising standards.
- It is beneficial that the distance arm has a feature selected from a group of features comprising an adjustable length by intermediate pieces, a telescopically extendable extension part, several connecting hooks at different locations along the length of the distance arm. Any such feature can be applied for arranging that a suitable distance arm or distance arms can be applied for promoting stability of the construction according to the invention.
- Preferably the at least one distance arm is mounted adjacent to a lowest part of the at least one flexible element or band.
- Further it is preferable that at ground-level the first and second vertically uprising standards are connected with harmonica arms. This is not only beneficial for securely moving the first and second vertical standards into a selected distance from each other, but is also beneficial for arranging that the vertically uprising standards are collectively movable to and fro a crane for handling monopiles. This enables that even a crane of limited capacity can be used for handling relatively heavy monopiles.
- Preferably the vertically uprising standards are mounted on rails. The rails can like the crane be mounted on a ship or be mounted on shore.
- The invention will hereinafter be further elucidated with reference to the drawing of some exemplary embodiments of a monopile fastening system according to the invention that is not limiting as to the appended claims.

For each flexible element orband 9 it holds that it is embodied with two extremities 9', 9'' distant from each other, and that a first extremity 9' of the at least one flexible element orband 9 connects to theupstanding arm 7 at a position distant from thepivot 8 which thearm 7 has in common with the first vertically uprising standard 5'. A second extremity 9'' of the at least one flexible element orband 9 which is distant from the first extremity 9' connects to the second vertically uprising standard 6'. -
Figure 3 schematically shows in a side view a part of the monopile support system of the invention whereindifferent diameter monopiles 3 are supported, notablymonopiles 3 of 8 m, 8.5 meters and 9 m diameter. With reference to bothfigure 3 andfigure 4 is shown that thesecond extremity 9" of the at least one flexible element orband 9 has a point of engagement with the second vertically uprising standard 6' at a height which is level or approximately level with a height at which the first extremity 9' of such at least one flexible element orband 9 connects to theupstanding arm 7 when saidarm 7 is in an (approximately) upright orientation. -
Figures 2 ,3 and4 show that at or near the connection of the at least one flexible element orband 9 with theupstanding arm 7 of the first vertically uprising standard 5' and at or near the point of engagement of the at least one flexible element orband 9 with the second vertically uprising standard 6',engagement blocks monopile 3. Theengagement blocks -
Figures 3 and4 show that eachengagement block monopile 3. - To match different length of the flexible element or band or flexible element or
bands 9 it is shown infigure 4 that the second standard 6' is provided withmultiple connectors 12 for the at least one flexible element orband 9. This could likewise be embodied on theupstanding arm 7 or another part of the first standard 5'. -
