Abstract

According to the invention, there is provided a device for a winch (2) for pulling a riser in to a fixed or floating offshore installation (1), wherein an actuator-operated manipulator arm (6) is attached to the winch (2). The manipulator arm (6) is able to guide a wire (3) with which the riser is hoisted up, the manipulator arm (6) pulling the riser in a horizontal direction into the desired installation position once the riser has been hoisted up to the right height. According to the invention, there is also provided a method for a winch (2) as disclosed above.

Description

Device and method for a winch for pulling a riser up to a fixed or floating offshore installation
The present application relates to a device and a method for a winch, as disclosed respectively in the preamble of independent claims 1 and 5.
In previously known solutions, risers are pulled up from subsea installations for securement on oil platforms using fixedly mounted winches which by means of blocks and guide pulleys are directed to the pull-up point of the riser in question. This solution takes up large areas on deck, and involves risks in connection with tensioning and possible breaks in the steel wire rope. When risers are to be placed in their intended point of suspension, the hoisting wire must be controlled by means of other winches (tugger winches) for positioning prior to lowering to the locking point. In the same way as for the hoisting winch, pull-in at the different locking points will involve danger when blocks and guide pulleys are used.
Therefore, for riser connection, previously known solutions make use of a winch for pulling the riser up to the securement point on the rig. When sufficient height/position has been reached, the riser is thus brought into position for securement and connection, and this pulling in is usually carried out using winches that pull the hoisting wire in to the fastening position. This operation thus involves a huge risk of damage to equipment and injury to crew, and requires extra manpower.
According to the invention, the aforementioned problems or defects are sought to be solved, and the aforementioned risks reduced or eliminated by means of a device and a method as disclosed respectively in the characterising clause of independent claims 1 and 5.
Advantageous embodiments of the invention are set forth in the dependent claims.
The invention is described in more detail below, with reference to the attached drawings wherein:
Figures Ia and Ib show a first embodiment of the device according to the invention in two different positions; and
Figure 2 shows a second embodiment of the device according to the invention. Referring first to Figs. Ia and Ib, there is provided on an installation 1, for example, an oil platform or a drilling vessel, a winch 2 for lateral movement to a required point for the pulling in of a (non-illustrated) riser hanging from a wire 3 with mounted slips 4. When the wire 3 with the riser has been hoisted up to the necessary height (the position shown in Figure Ia), it is precision-positioned over a required locking point 5 with a locking seat by another lateral movement into the exact position. The wire 3 with the riser is then pulled in to the locking point 5 (the position shown in Figure Ib) before it is lowered into locking contact at the locking point 5 with the slips 4 located in the locking seat. The pulling in is performed using a manipulator arm 6 with sufficient force to position the riser to the locking point 5 before lowering it to the locking seat.
The manipulator arm 6 controls the position of the winch wire 3 and prevents undesired movement. The arm 6 is fastened to the winch 2, and is dimensioned to pull the wire 3 in to the correct securement point after sufficient height has been reached, as mentioned above.
The winch wire 3 is first run to the correct height for securement/locking. The manipulator arm 6 is then moved sideways in the horizontal plane and brings the riser into the right position for securement/locking. Then the arm 6 pulls the riser in to the locking point 5, as indicated by the arrow in Figure Ib.
The manipulator arm 6 advantageously also controls the winding of the wire 3 on the winch drum during the reeling in and paying out of the winch wire 3. The movements of the arm 6 are preferably made in that one or more hydraulic cylinders 7 are driven to desired force and position. Instead of hydraulic cylinders 7, it is conceivable that other actuators, as for example electric or pneumatic actuators, may be used.
The manipulator arm 6 shown in Figures Ia and Ib includes a parallelogram linkage 8, where, between two diagonal linkage points, there is arranged a hydraulic cylinder 7. Two rollers 9 are attached to one end of the manipulator arm 6 for guiding the wire 3.
Figure 2 shows an alternative embodiment of the manipulator arm 6, this embodiment being essentially U-shaped and supported in the winch 2 at both ends of the U. Two hydraulic cylinders 7 are arranged between two points of attachment on the winch 2 and two attachment lugs 10 at a distance from each end of the U. In the centre of the U is arranged a roller 9 for guiding the winch wire 3. The manipulator arm 6 may, in addition, be equipped with a smaller (non-illustrated) winch for rigging assistance and the pulling in of steel wire rope from auxiliary vessels. The use of the manipulator arm 6 for this purpose allows an efficient handling of auxiliary equipment during the installation of risers.
