<p>There is provided a construction for a traction winch for serving a hoisting line, for implementing a heave compensation, comprising two mutually separated traction drums (32, 34) whose drum outer surfaces each comprise at least two mutually separated line tracks (41, 43; 45, 47) for arranging the line in a number of loops around the drums, and it is characterized in that a number of regulating sheaves (60, 62) are adapted to form extra loops of line between the traction drums (41 to 47) and the spooling up unit (10), in that the regulating sheaves (61, 62) are adapted for individual operation (70, 72), or to be freely coupled, for regulating the tension in the line between the traction drums (32, 34) and the spooling up unit (10). The invention concerns also an apparatus for a winch for serving a hoisting line, for implementing heave compensation, comprising in series: a traction winch, a tightening unit and a secondary winch for the line, wherein the tightening unit arrangement provides a buffer for holding the line between the traction winch and the secondary winch with substantially constant tension. There is also described a use thereof.</p> |
