  • a special object of the invention is to provide a pulling tool which in addition to the described object is equally well suited for pulling single pipelines, i.e. pipelines with no need for angular position before the coupling operation as well as for conduit or pipeline bundles requiring an accurate angular positioning be- fore being coupled to a complementary conduit or pipeline bundle mounted on the sea bottom installation.
  • the tool unit in accordance with the invention for pulling and optionally angular positioning and coupling of an initially loose free end on a submarine conduit, for instance in position on the sea bottom, to a complementary conduit mounted on a sea bottom installation is of the kind wherein the tool includes a downwardly open substantially U-shaped longitudinal yoke for receiving and positioning the submarine conduit in connection with the coupling, and includes further winch equipment mounted on the yoke or on a supporting frame in order to pull up the end section of the submarine conduit, means for axial movement of the submarine conduit in pulled-in position in the yoke for coupling the ends of conduits together, the end section of the submarine conduit encased in a mantle or jacket conforming to the transverse dimension of the yoke, and attachment means or fitting attached to the mantle for fastening a hoisting cable extending from the above mounted winch, and the invention is characterized in that the mantle on the end section of the submarine conduit at least along a part of its length is provided with non-circular cross-

  • Figures 4 a, b, c and d show schematic cross-sections through a under- water conveyer located on a sea bottom and illustrating the initial steps during the hauling procedure
  • Figures 5 a, b, c and d illustrate four different steps illustrating the final or terminating part of the pulling and positioning of the pipeline or conductor to its final position in the U-shaped tool.
  • Figure 1 is a side view illustrating a tool in accordance with the invention during the hauling of a submarine conveyer or pipeline 2 which is located on a sea bottom 3, frequently at some distance from the ROW supported tool which is mounted on a subsea installation 4.
  • On the installation 4 is mounted a permanently installed subsea conduit unit 8 with coupling means 10.
  • the operative ROV 12 seated on the support frame 14 is carrying a tool 16 which during the hauling and coupling operation is positioned on the installed bottom frame 4 or as shown on a support frame 6 in front of the stationary unit 8.

  • a drum winch 22 On top of the tool 16 is mounted a drum winch 22 with a pulling wire or cable 24 which in operation extends down through the top wall of the U- shaped yoke 26 the design of which appear in detail from figures 5a-d.
  • the winch 22 may optionally be mounted in the frame 14.
  • the yoke 26 consists as shown of a downwardly open U-shaped clamp device which preferably is made in the shape of one single integral unit or optionally in the shape of two or more interlinked parts.
  • the yoke has parallel side faces 28, 28 the upper ends of which are interconnected with a preferably arched top part 30 which in centre is provided with a suitable opening 32 for passing through the pulling wire 24.
  • the lower parts 31 ,31 diverges outwardly in per see known fashion in order to facilitate the introduction of the submarine conduit or pipeline.
  • the tool in accordance with the invention can be used for submarine conduits consisting of one single pipe or for submarine conduits comprising a mantle enveloping two ore more pipelines, cables or alike positioned in one single termination.
  • the tool in accordance with the invention is accomplished the necessary rotational adjustment prior to the coupling to a complementary submarine conduit mounted on a sea bottom frame.
  • the end section thereof must usually be provided with a mantle or termination as shown in the figures 1-3, firstly because the mantle diameter is adapted to the transverse opening of the yoke, and secondly in order to furnish the conduit with attachments 38 for the pulling wire.
  • the submarine conduit will usually have an oblique position both in the vertical and the horizontal plane as shown in figures 1 and 2, but will during the further hauling up from the sea bottom be vertically positioned from an oblique position as shown in figure 2 into an aligned position as shown in figure 3 obtained by the diverted inlet sections 31 ,31 lowermost on the yoke as shown in figure 5.
  • conduit mantle 36 is designed with non-circular cross-section and not circular cross-section, more particularly presenting two parallel side faces in mutual distance between which correspond to the distance or space between the parallel side faces in the yoke.
  • the shape of the mantle appear best from figure 5.
  • the submarine conduit is encircled by a termination or mantle 36 provided with parallel side faces 42, 42, a spherical top section 44 and preferably with a somewhat extended section 46 at the other end, preferably ending into a substantially flat cross-sectional end face 48 (see figure 4c).
  • the mantle is further preferably equipped with a pivotable bellyband 40 equipped with mounting means 38 for attaching a pulling wire 24.
  • the bellyband is preferably such arranged that it may pivot freely inside a defined angle, preferably 90° from a centre position, but dependent on the actual type of conduit it may be suitable to reduce or expand the pivoting possibilities for the bellyband.
  • Figures 4 a, b c and d illustrates the initial steps of the conduit in connection with the attachment of the pulling wire.
  • Figure 4a shows a conduit terminal with a non-circular mantle 36 as described, and where the submarine conduit incidentally is positioned on a sea bottom with the wire mounting 38 on a pivotable bellyband pointing straight down into the sea bottom as shown in figure 4a.
  • the bellyband is however provided with one or more auxiliary attachments in the shape of hook 50 on opposite side of the mantle, respectively.
  • a manipulating tool 52 on a ROV 12 the bellyband is moved 90° to the left, such that the mounting means 38 is accessible on the right side of the mantle as shown in figure 4b.
  • the pulling wire 24 is pulled down by the ROV tool and is attached in the mounting as shown in figure 4c.
  • the hauling may be initiated as shown in figure 4d.
  • the conduit When the conduit is pulled up into position as shown in figure 1 it will be lifted up from the sea bottom simultaneously as existing torsional stretches in the conduit 2 will be continuously equalised by the pivoting of the bellyband.
  • the conduit In the case with single pipelines having circular termination or mantle, the conduit can now be pulled directly up into top position in the yoke 26 as shown in figure 5d.
  • the conduit mantle comprises several built-in conduits, cables or alike, and such a mantle must be rotationally positioned prior to proceeding with the inter-coupling.
  • Figures 5a, b, c and d illustrate the rotational adjustment accomplished by the invention during the hauling up into the yoke prior to the finalising adjustment of the submarine conduit. If the mantle for instance contacts the opposing side faces as shown in figure 5a, it will pivot to the left because the distance from the mounting point for the pulling wire on the mantle on the right side is shorter than the corresponding distance from the pulling wire to the yoke wall on the left side, due to the extension of the mantle on the left side as shown. Consequently the mantle will pivot as shown in figure 5b, such that the pivoting is substantially completed as shown.
  • the mantle is pulled completely up into longitudinal contact with the top wall of the yoke, having into effect that the submarine conduit is completely positioned and adjusted both angularly and longitudinally such that the longitudinal axis through the conduit runs flush with the axis through the complementary conduit mounted on the bottom frame such that the aimed inter-couple of the two conduits can be accomplished.
  • the tool When the submarine conduit has been pulled up into the position shown in figure 3, the tool is moved forwards along the posts 18 in order to position the coupling termination against the complementary conduit mounted on the bottom based frame.
  • a winch having pivotal mounting on the tool, and wherein the support and tool is provided with operating cylinders such that the final hauling can take place directly by the hydraulic cylinders and thereby reduce the necessary power rating of the winch.
