Abstract
Device, system and method for protecting towed marine survey equipment from line entanglement are provided. A cutter device has a mounting mechanism configured to fixedly attach at a predetermined position along a cable used for towing, and one or more cutting structures. The cutting structures are attached to and extend away from the mounting mechanism, being configured to cut lines that get caught by the cutting structures or slide along the cable to the predetermined position.

A cutter device configured to be mounted on a towed cable, the cutter device comprising:
- a mounting mechanism configured to fixedly attach at a predetermined position along the towed cable;
- and
- one or more cutting structures, which are attached to and extending away from the mounting mechanism and are configured to cut lines that get caught by the cutting structures or that slide downstream the towed cable to the predetermined position.
A marine survey system, comprising:
- one or more streamers attached directly or indirectly to the vessel to tow survey equipment according to a predetermined survey geometry;
- and
- at least one cutter device mounted on one of the one or more streamers, the at least one cutter device including
- a mounting mechanism configured to fixedly attach at a predetermined position along the one of the streamers;
- and
- one or more cutting structures attached to and extending away from the mounting mechanism, which are configured to cut lines that get caught by the cutting structures or slide along the one of the streamers to the predetermined position.
A method for protecting from line entangling a piece of marine survey equipment, the method comprising:
- mounting a cutter device on a cable, at a predetermined position upstream from the piece of marine survey equipment;
- and
- towing the piece of marine survey equipment in the water using the cable,
- wherein the cutter device includes a mounting mechanism configured to fixedly attach to the cable, and one or more cutting structures attached to and extending away from the mounting mechanism, which are configured to cut lines that get caught by the cutting structures or slide downstream the cable to the predetermined position.
