Abstract
Cutting device, method and use are for cutting of a line extending from a floating vessel. The cutting device is structured for placement on the vessel. The cutting device comprises: at least one guide structured for directional steering of the line past a cutting area for the line; and at least one of the following cutting-promoting devices: at least one induction coil device directed inwards toward the cutting area and structured for heating, hence weakening, of the line within the cutting area; and at least one moveable cutting knife with an opposite contact surface directed inwards toward the cutting area and also structured for cutting of the line within the cutting area.
Claims23
A cutting device for mechanical cutting of a load-burdened chain extending from a floating vessel, the chain having a plurality of chain links, the cutting device comprising:
- a guide device that guides the chain through a cutting area;
- parallel first and second cutting knives that are configured to move into the cutting area to simultaneously cut completely through a first link of the plurality of chain links;
- parallel third and fourth cutting knives that are opposed to the first and second cutting knives, the third and fourth cutting knives being configured to move into the cutting area to simultaneously cut completely through the first link;
- and
- a first moving device that is configured to simultaneously move the first, second, third and fourth cutting knives into the cutting area so that the first and second cutting knives engage with the third and fourth cutting knives, respectively, to simultaneously cut through the first link.
A cutting arrangement comprising:
- a floating vessel;
- a load-burdened chain having a plurality of chain links and extending from the floating vessel;
- a cutting device disposed on the floating vessel, the cutting device comprising:
- a guide that is configured to guide the chain through a cutting area;
- parallel first and second cutting knives that are configured to vertically move into the cutting area to simultaneously cut completely through a first link in the plurality of chain links;
- and
- a first moving device that is configured to move the first and second cutting knives into the cutting area so that the first and second cutting knives simultaneously cut completely through the first link.
