Definitions
- the present invention relates to methods for lowering and hoisting, respectively, of a load to or from the ocean floor from a vessel that floats on the ocean surface, where a first lifting line from a load holding winch is coupled to the load and a second lifting line from a positioning winch is coupled to the load.
- This description has as an aim to describe an invention relating to a concept for installation and lifting that comprises equipment for anchor handling operations, and also a crane or positioning winch for subsea operations.
- the system is initially described installed on an anchor handling vessel, but can also be adapted to other vessels, such as barges, cargo ships, etc.
- the core of the system is initially described installed on an anchor handling vessel, but can also be adapted to other vessels, such as barges, cargo ships, etc.
- invention is that one gets a possibility to handle a load, with a crane or the like, that is much bigger than the lifting capacity of the crane by using, for example, an anchor handling winch (load holding winch) in a constant tension mode, while the crane can operate in an active heave mode.
- an anchor handling winch load holding winch
- the object of the invention comprises use of one of the drums belonging to the anchor handling winch as a load holding winch, while the subsea crane/positioning winch positions the load.
- the crane/positioning winch can be coupled to the main line with the help of, for example, a triangle plate.
- a method for the lowering of a load to the ocean floor from a vessel that floats on the ocean surface comprising the features:
- the positioning winch lets out the second lifting line for the lowering of the load, while the load holding winch follows behind by releasing the first lifting line.
- a method for the hoisting of a load from the ocean floor by a vessel that floats on the ocean surface comprising the features:
- the load holding winch lifts the load in a constant tension mode and the positioning winch lifts the load in a constant tension mode .
- the fraction of the weight that the load holding winch takes up can be more than 80% of the weight of the load and the fraction of the weight that the positioning winch takes up can be less than 20% of the weight of the load.
- the positioning winch is preferably mounted to a deck crane on the vessel.
- the deck crane can be set in an active heave compensation mode.
- the deck crane can be set in an active heave compensation mode.
- FIG. 1 shows a diagram of a vessel equipped with a crane and a winch.
- the figure shows a vessel 10, such as an anchor handling vessel which is equipped with a load handling winch 12, such as an anchor handling winch.
- the vessel 10 is further equipped with a deck crane 14 fitted with a heave
- a positioning winch is mounted, indicated by the reference number 14a, such as a winch for subsea operations.
- the heave compensated crane 14 can, for example, comprise a lower vertical boom and an upper horizontal boom that are mutually connected via an articulated piece, and where the vertical boom is
- a tension stay can be arranged between the base socket and the articulated piece at a distance from the vertical boom and on the whole in parallel with this, in a normal position for the crane.
- the vertical boom can be driven by at least one cylinder and the movement of the upper crane boom with respect to the lower boom can be driven by an intermediate-lying cylinder arrangement, where the cylinder arrangement can comprise at least one single acting cylinder and at least one double acting cylinder.
- Other cranes that can be heave compensated can, of course, be used.
- first and second lifting lines 20,22 where the lifting lines can run, for example, over the stern roller of the vessel, indicated by the reference number 26, or through the ship's moon pool 16. In the latter case, the lifting line 20 can then run over one or more pulleys 28 or the like mounted on the deck, or in the moon pool .
- the first lifting line 20 runs from the load handling winch 12 and to the load 18 and the second lifting line 22 runs from the positioning winch 14a.
- the first and the second lifting line can be connected to the load 18 with the help of, for example, a triangle plate 24 or the like.
- the crane/positioning winch When the crane/positioning winch is connected, it can lift with about 10% of the weight of the object. Thereafter the load holding winch is set in a constant tension mode and adjusted so that about 90% of the weight is compensated. The crane/positioning winch can now be used to guide the load down to the ocean floor, while the load holding winch follows. On placing the load on the ocean floor the crane/positioning winch can be set in an active heave compensation mode and the load can be put down without being influenced by the movements of the ship.
- the crane/positioning winch is used to hold the lifting appliance at the connection, and if necessary in an active heave compensation mode.
- the crane can be set in a constant tension mode, and the load holding winch can lift the load in a constant tension mode free from the ocean floor.
