Description

Apparatus and method for placement of a construction on the bottom of the sea
The invention relates to an apparatus and method for placement of a construction on the bottom of the sea, using a barge that is provided with legs for stably positioning the barge on the bottom of the sea, wherein the barge is fixable at 5 a pre-defined height of the legs.
The barge is used to transport the construction over the sea near to the position at which the construction is to be located on the bottom of the sea. After arrival at said position the operation has to be carried out by which the construction 10 can be converted from its transport position to its eventual erected position at the bottom of the sea.
The inventor has developed a new concept to implement this operation with an apparatus and method incorporating the features of one or more of the appended claims.
15 In a first aspect of the invention a handling device is mounted on the barge for supporting and holding the construction in a first transport position, which handling device is arranged to move the construction from the first, transport position to a second position in which the construction is placed at the bot-20 tom of the sea. To this effect the handling device is arranged with a first transport position wherein the construction is essentially horizontal, and a second position in which the construction is essentially vertical.
In another aspect of the invention the handling device 25 comprises adjustable clamping means for holding the construction while it is supported by the handling device. Preferably the clamping means has a clamping position in which it holds the construction, and a release position in which the construction is removable from the clamping means. This can effectively be 30 implemented with the clamping means embodied with arms and the handling device further comprising a frame, wherein the arms can pivot on the frame by the operation of first hydraulic jacks connected to both the frame and the arms.
In the method of the invention the barge is first fixed 35 at a pre-defined height of the legs, following which the construction may be moved from the first essentially horizontal transport position to the second essentially vertical position 2 in which the construction is placed at the bottom of the sea. Prior to moving the construction to the second essentially vertical position, at least part of the construction is moved over an edge of the barge. This may be done until the center of grav-5 ity of the construction is located slightly beyond the edge of the barge, so that it may assist in converting the construction from the first horizontal position to the second vertical position in a manner to be explained hereinafter.
In order to arrange that the center of gravity of the 10 construction may be conveniently moved over the edge of the barge, it is desirable that, the handling device is movable on top of the barge, preferably to the extent that the construction that is held by the handling device can be at least in part, be moved over the barge's edge. In a convenient arrangement this 15 can be implemented with the handling device arranged as a frame that is movable along a skidtrack on top of the barge.
A further preferable feature is that the handling device is arranged to be pivotal around the edge of the barge, so as to enable that it is convertible from an essentially horizon-20 ta.1 position to an essentially vertical position and make possible that the construction can be tilted from an essentially horizontal position to an essentially vertical position. In order to execute the tilting of the handling device it is preferred that the handling device is provided with a second hy-25 draulic jack.
During the tilting of the construction from the first essentially horizontal position to the second essentially vertical position, the handling device maintains holding the construction. Preferably the barge is then also provided with a 30 winch to which a line is connected that on the far side of the winch is connected to the construction, whereby the winch gradually release the line in order to control the position along the height of the construction at which it is held by the handling device during movement from the first essentially horizontal 35 transport position to the second essentially vertical position, from which the construction is eventually lowered to the bottom of the sea.
In order to avoid damage to the construction it is also preferable that guide wheels contact the construction during 40 movement of the construction from the first essentially horizontal position to the second essentially vertical position, and 3 its eventual resting position when it is placed at the bottom of the sea. To this end it is preferable that the guide wheels are mounted on the clamping means, so that the guide wheels can contact the construction when the clamping means is in the clamping 5 position.
The invention will hereinafter be further elucidated with reference to the drawing and with reference to an exemplary embodiment of the apparatus of the invention and a method of its operation.
10 In the drawing: -figure IA, IB and 1C show respectively a side view and frontal view of the barge of the invention, and a detailed view of the handling device mounted on the barge of the invention; -figure 2 shows a top view of the barge of the inven- 15 tion; -figure 3A, 3B and 3C show the barge and handling device of figure IA, IB and 1C while carrying the load of a construction; -figure 4, 5, and 6 shows the barge of the invention 20 standing with its legs at the bottom of the sea, whilst, the construction that is supported by the barge is moved from the horizontal transport position to an initial vertical position from which it will be lowered until it stands at the bottom of the sea.
25 Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.
With reference first to figure 1A and 3A, the apparatus of the invention is shown which is embodied with a barge 1 that is provided with legs for stably positioning the barge 1 on the 30 bottom of the sea. The barge 1 is fixable at a pre-defined height of the legs which is clearly shown in figure 4.
On the barge 1 an handling device 2 is mounted for supporting and holding the construction 11 in a first horizontal transport position as shown in figure 3A. The handling device 2 35 is arranged to move the construction 11 from a first transport position (also shown in figure 4) to a second position that is essentially vertical in which the construction 11 can be placed at the bottom of the sea. The transition from the first horizontal position to the second vertical position is shown in figures 40 4, 5 and 6 respectively.
Preferably the handling device 2 is movable on top of 4 the barge 1 to the extent that the construction 11 that is held by the handling device 2 is at least in part movable over an edge of the barge 1. Most suitably the handling device 2 is therefore arranged as a frame that is movable along a skidtrack 5 5 on top of the barge 1 as shown in figures 1C, 2, and 3C.
The conversion of the construction 11 from the horizontal to the vertical position will be elucidated further with reference to figures 4, 5 and 6. Figure 4 shows an initial position of the handling device or frame 2 on top of the barge 1, 10 and figure 5 shows a subsequent intermediate position of the frame wherein it is also shown that the frame 2 can pivot to this end around the edge of the barge 1. To be specific, it is preferred that the frame or handling device 2 can pivot around the edge of the barge 1 from an essentially horizontal position 15 to an essentially vertical position. Particularly figure 5 shows that the handling device 2 is provided with a second hydraulic jack 6 for tilting the handling device 2 from the first essentially horizontal transport position to the second essentially vertical position from which the construction 11 may be placed 20 at the bottom of the sea.
With reference again to figures 1C and 3C it is shown that the handling device 2 comprises adjustable clamping means 3 for holding the construction 11 (this is shown in figure 3C) while it is supported by the handling device 2. Figure 3C shows 25 the clamping position in which the clamping means 3 holds the construction, and the release position in which the construction is removable from the clamping means 3 is shown in figure 1C.
The clamping means 3 may suitably be embodied with arms 3 that can pivot on the handling device's frame 2 by the operation of 30 first hydraulic jacks 9 connected to both the frame 2 and the arms 3.
Most clearly shown in figure 3C is that the clamping means 3 is provided with guide wheels 13 that contact the construction 11 when the clamping means 3 is in the clamping posi-35 tion.
Figure IA, 3A and 4 show that the barge 1 is further provided with a winch 4 to which a line is connected that on the far side of the winch 4 is connectable to the construction 11 in order to control the position at which the construction 11 is 40 held by the handling device 2, at least during movement from the first transport position (see figure 4) to the second position 5 (see figure 6), and also thereafter when the construction 11 is eventually lowered and placed at the bottom of the sea.
With reference to figures 4, 5, and 6 the method of placing a construction 11 of the bottom of the sea is briefly 5 discussed hereinafter.
Figure 4 shows that the barge 1 carrying the load of the construction 11 is first fixed at a pre-defined height of its legs, following which the construction 11 is moved far enough over an edge of the barge 1 until its center of gravity 10 lies beyond this edge of the barge 1 and above to sea. After this is done the construction 11 is moved from a first essentially horizontal transport position as shown in figure 4, via an intermediate position shown in figure 5, to a second essentially vertical position shown in figure 6 from which the con-15 struction 11 may be lowered until it eventually rests at the bottom of the sea.
During this tilting of the construction 11 from an essentially horizontal position to an essentially vertical position, the handling device 2 maintains holding the construction 20 11. Also during this tilting operation as well as during the fi nal lowering of the construction 11, a winch 4 on the barge 1 gradually releases a line connected to the construction 11 in order to control the position at which the construction 11 is held by the handling device 2.
25 An important feature to avoid damage to the construc tion 11 is that, the earlier mentioned guide wheels 13 shown in figure 1C and 3C contact the construction 11 during movement of the construction 11 from the first essentially horizontal position to the second essentially vertical position and the subse-30 quent. lowering of the construction 11 for its placement at the bottom of the sea.
