Abstract (en)
[origin: WO2014031004A1] A method is described for the lowering of a load (18) to the ocean floor from a vessel (10) that floats on the ocean surface, comprising the features: to couple a first lifting line (20) from a load holding winch (12) to the load (18), to connect a second lifting line (22) from a positioning winch (14a) to the load (18) and to adjust the positioning winch (14a) so that a fraction of the weight of the load (18) is taken up, to set the load holding winch (12) in a constant tension mode and to adjust the load holding winch (12) so that a fraction of the weight of the load is compensated, where the fraction of the weight that the load holding winch (12) takes up is greater than the fraction of the weight which the positioning winch (14a) takes up, and during lowering of the load (18), the positioning winch (14a) lets out the second lifting line (22) for lowering of the load (18), while the load holding winch (12) follows behind with letting out the first lifting line (20). A method for hoisting of the load is also described.
