NOR Subsea Winch 10Te with Lifting Frame

Description

The NOR Subsea Winch 10Te with Lifting Frame is a hydraulic subsea winch intended for offshore subsea pulling operations. The winch is operated locally and powered hydraulically from an external HPU supplied by ROV, through a 60 mm valve stab.

The NOR Subsea Winch 10Te has a maximum rope pull of 10 Te. Operating pressure is 226 bar with an oil flow of 73 l/min, and maximum back pressure is 5 bar on the return line and 1.5 bar on the drain line. Rope speed is 10 m/min on the 1st layer, 10.8 m/min on the 2nd layer, 11.6 m/min on the 3rd layer and 12.5 m/min on the 4th layer.

The drum is 800 mm long with a flange diameter of 1000 mm, and the rope is stated as 28 mm (257 m at the 4th layer). The winch alone weighs 1680 kg in air; with the lifting frame it weighs 2912 kg in air and 2537 kg in water. Stated dimensions are 3053 mm length, 2422 mm width and 1459 mm height. The winch is supplied on a certified lifting frame, which can be delivered with mud skirts for placement on soft seabed (optional).
