Monopile fastening system
The invention relates to a monopile fastening system for retaining a monopile 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 discloses such a system for retaining an elongated monopile during transport ashore or offshore on sea. The known system comprises two pivotable supporting elements which are arranged at a distance from each other that during use support the monopile. The monopile is secured against movement in the longitudinal direction by friction between the supporting elements and the monopile. The pivotable supporting elements are actuated by hydraulic cylinders to position them with the proper orientation to receive and support the monopile .
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 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 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 vertical standards, wherein at least a first vertical standard is provided with at least one pivotable and upstanding arm having its pivot in common with the first vertical standard, and that at least one flexible element or band is provided to connect the first vertical standard with a second vertical 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 vertical standard, and that a second extremity of the at least one flexible element or band connects to the second vertical standard.
The construction of the 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 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 vertical 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 vertical 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 vertical 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 provid ing 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 vertical standard and at or near the point of engagement of the at least one flexible element or band with the second vertical 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 vertical standards are movable with respect to each other.
Particularly when the first and second vertical 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 vertical standards are provided with at least one distance arm to secure a predetermined distance between the first and second vertical 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 vertical 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 vertical 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 vertical 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.
In the drawing:
-figure 1 shows a monopile fastening system according to the invention as mounted on a ship;
-figure 2 shows the monopile fastening system of figure 1 ;
-figure 3 schematically shows the use of a monopile fastening system of the invention with different diameter monopiles;
-figure 4 shows an embodiment of the monopile fastening system of the invention suitable for adjusting to different length of flexible element or bands;
-figure 5 shows several distance arms for use with a monopile fastening system of the invention; and
-figure 6 shows the mobile fastening system of the invention embodied with harmonica arms at ground-level.
Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.
Making reference to figure 1 a monopile fastening system 1 is shown at the railings at opposite sides of a ship for retaining monopiles 3 during transport.
As is better shown in figure 2 the system 1 of the invention comprises a frame 4 for supporting the monopile or monopiles, which frame 4 comprises supporting elements 5, 6 at a predetermined distance from each other, which distance is selected to enable the frame 4 to receive and support the monopiles. The supporting elements 5, 6 are embodied as vertical standards 5', 6', wherein at least a first vertical standard 5' is provided with one or more pivotable and upstanding arms 7. Each arm 7 has its pivot 8 in common with the first vertical standard 5' .
Further figure 2 shows that one or more flexible element or bands 9 are provided to connect the first vertical standard 5' with a second vertical standard 6'. For each flexible element or band 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 or band 9 connects to the upstanding arm 7 at a position distant from the pivot 8 which the arm 7 has in common with the first vertical standard 5'. A second extremity 9'' of the at least one flexible element or band 9 which is distant from the first extremity 9' connects to the second vertical standard 6'.
Figure 3 schematically shows in a side view a part of the monopile support system of the invention wherein different diameter monopiles 3 are supported, notably monopiles 3 of 8 m, 8.5 meters and 9 m diameter. With reference to both figure and figure 4 is shown that the second extremity 9'' of the at least one flexible element or band 9 has a point of engagement with the second vertical 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 or band 9 connects to the upstanding arm 7 when said arm 7 is in an (approximately) upright orientation.
Figures 2, 3 and 4 show that at or near the connection of the at least one flexible element or band 9 with the upstanding arm 7 of the first vertical standard 5' and at or near the point of engagement of the at least one flexible element or band 9 with the second vertical standard 6', engagement blocks 10, 11 are provided for engaging and resting against the monopile 3. The engagement blocks 10, 11 can be flat or have a curved surface.
Figures 3 and 4 show that each engagement block 10, 11 is provided with a curved surface 10', 11' that approximately matches the curvature of the monopile 3.
To match different length of the flexible element or band or flexible element or bands 9 it is shown in figure 4 that the second standard 6' is provided with multiple connectors 12 for the at least one flexible element or band 9. This could likewise be embodied on the upstanding arm 7 or another part of the first standard 5'.
Figure 6 depicts that the first and second vertical standards 5', 6' are movable with respect to each other. This is in this example embodied with harmonica arms 13, 14 connecting the first and second vertical standards 5', 6' at ground-level. Going from left to right in figure 6 the harmonica arms 13, 14 are shown in a collapsed situation, a half angled orientation, and in a straight orientation in each-others extended direction, thus providing for less or more room between any combination of first vertical standard 5' and second vertical standard 6' of the frame.
Turning back to figure 2 it is shown that the first and second vertical standards 5', 6' are provided with at least one distance arm 15 to secure a predetermined distance between the first and second vertical standards 5' , 6' . The at least one distance arm 15 is mounted adjacent to a lowest part of the at least one flexible element or band 9 to provide best results in stability. Figure 2 also shows that when multiple flexible element or bands 9 are used, the flexible element or bands 9 can cross each other.
Particularly but not only in relation to the movability of the first and second vertical standards 5', 6' , the distance arm 15 has a feature selected from a group of features comprising an adjustable length by intermediate pieces 15' (see figure 5 - in the middle), a telescopically extendable extension part 15'' (see figure 5 - top), several connecting hooks 15''' at different locations along the length of the distance arm 15 (see figure 5 - bottom). With any one of these features stably maintaining the distance between the first and second vertical standards 5', 6' can be maintained over their entire height.
Turning back to figure 1 it is remarked that the frame 4 comprising the vertical standards is movable to and fro a crane 16 for handling the monopiles 3. For this purpose it is appropriate that the vertical standards of the frame 4 are mounted on and movable over rails 17.
Although the invention has been discussed in the foregoing with reference to an exemplary embodiment of the monopile fastening system of the invention, the invention is not restricted to the particular embodiments as discussed herein, which can be varied in many ways without departing from the invention. The discussed exemplary embodiments shall therefore not be used to construe the appended claims strictly in accordance therewith.
