Abstract
A method and a marine towing system for towing streamers or sources. The towing system includes a connecting line; a first paravane connected to the connecting line, wherein the connecting line is configured to connect the first paravane to a vessel; a spur line connected to the first paravane and configured to provide a tension to maintain streamers apart from each other; and a second paravane connected to the connecting line, between the first paravane and the vessel. The second paravane is configured to increase an angle (α4) between the connecting line and the spur line.
Claims20
A marine towing system for towing streamers or sources, the towing system comprising:
- a connecting line connected to a connecting device;
- a first paravane connected to the connecting line through the connecting device, wherein the connecting line is configured to connect the first paravane to a vessel;
- a spur line connected to the first paravane and to the connecting line through the connecting device such that the spur line is located between the connecting device and heads of streamers, and the spur line is configured to provide a tension to maintain the heads of the streamers apart from each other;
- and
- a second paravane connected to the connecting line, at a location between the first paravane and the vessel,
- wherein the second paravane is configured to increase an angle (α4) between the connecting line and the spur line.
A marine towing system for towing streamers or sources, the towing system comprising:
- a connecting line;
- a first paravane connected to the connecting line, wherein the connecting line is configured to connect the first paravane to a vessel;
- a first spur line connected between the first paravane and a connecting device and configured to provide a tension to maintain streamers apart from each other;
- a second paravane connected to the first paravane through a connecting link;
- and
- a second spur line connected between the second paravane and the connecting device and configured to provide a further tension to maintain the streamers apart from each other,
- wherein the connecting device is connected to the streamers.
A method for towing streamers or sources with a marine towing system, the method comprising:
- attaching a first paravane to a first end of a connecting line through a connecting device, wherein the connecting line is configured to connect with a second end to a vessel;
- attaching a spur line to the first paravane through the connecting device such that the spur line is located between the connecting device and heads of streamers;
- attaching a second paravane to the connecting line, at a location between the first paravane and the vessel;
- and
- adjusting settings of the second paravane to achieve a desired angle (α4) between the connecting line and the spur line.
A method for towing streamers or sources with a marine towing system, the method comprising:
- attaching a first paravane to a first end of a connecting line, wherein the connecting line is configured to connect with a second end to a vessel;
- attaching a first spur line between the first paravane and a connecting device and connecting the first spur line to the first end of the connecting line;
- attaching a second paravane to the first paravane through a connecting link;
- attaching a second spur line between the second paravane and the connecting device;
- connecting the connecting device to a streamer;
- and
- adjusting settings of the first and second paravanes to achieve a desired lift on a spread rope connected between the connecting device and an adjacent connecting device.
