Abstract
The present invention relates to a wire cutting system and method for subsea cutting of large structures (6). The system includes two feeding towers (2) with feeding tower first ends secured into a seabed floor. A crossbeam (1) is located between the two feeding towers (2). Wire feeding trolleys (8) are connected to the feeding towers (2), whereby the wire feeding trolleys (8) are allowed to move a cutting distance along the feeding towers. A cutting wire (4) traverses between the wire feeding trolleys.
Claims14
A seabed attachable subsea wire sawing system comprising:
- a first feeding tower with a first feeding tower first end with a seabed attachment portion for attachment to a seabed floor;
- a second feeding tower with a second feeding tower first end with a seabed attachment portion for attachment to the seabed floor;
- a first wire feeding trolley connected to and linearly displaceable a cutting distance along the first feeding tower;
- a second wire feeding trolley connected to and linearly displaceable a cutting distance along the second feeding tower;
- at least two cutting wire pulleys on each wire feeding trolley whereof at least one cutting wire pulley on each wire feeding trolley is motorized;
- wherein the cutting wire forms a loop and traverses between the two cutting wire pulleys on each first wire feeding trolley;
- an adjustable crossbeam located between the first feeding tower and the second feeding tower above the first wire feeding trolley, the second wire feeding trolley;
- at least one crossbeam actuator assembly in connection with the adjustable crossbeam enabling adjustment of a distance between the first feeding tower and the second feeding tower at the location of the crossbeam.
