Ship and a method adapted to generate tensile stresses in a pull line extended between the ships and an object to which a pull is to be applied

摘要

The present invention concerns a ship which is adapted to generate tensile stresses in a pull line extending between a ship and an object to which a pull is to be applied. The ship, which includes at least one line pull winch, includes equipment in the form of a holding line and a holding line anchorage which is laid out in the desired tensioning direction from the object with a view to generating tensile stresses. At its stern, the ship moreover has at least one line entry opening and force-absorbing line supports for the pull and holding lines. At least one of the supports is adapted to guide the line concerned in a direction toward the line pull winch. The force-absorbing line supports are interconnected via a tension-absorbing constructional element. The resulting ship is capable of generating very high pull forces in a pull line extending in an arbitrary direction from an object to which a pull is to be applied. The invention also concerns a method of applying a pull from a ship of the invention to a pull line, and a use of a ship of the invention for testing the tensile strength of anchorages, for applying a pull to grounded ships and for applying a pull to vessels during towing.
