Interconnecting tow members of a marine seismic system

摘要

A marine seismic system having a tow vessel; a first tow member connected to the tow vessel; a second tow member connected to the tow vessel; a first distance member having a first end connected to the first tow member and a second end connected to the second tow member; and a first attachment device connecting the first end to the first tow member, the first attachment member operational between an engaged position securing the first end of the distance member in a fixed position relative to the first tow member and a disengaged position permitting the first attachment device to move along a portion of the first tow member.

主权项

1. A marine seismic system comprising:
a first tow member, a second tow member and a third tow member deployed from a tow vessel in a spaced apart relationship; an inner attachment device comprising an internal bore through which the first tow member is disposed and an inner locking mechanism operational from an engaged position securing the inner attachment device in a fixed position relative to the first tow member and a disengaged position permitting the inner attachment device to move on the first tow member; an outer attachment device comprising an internal bore through which the first tow member is disposed and an outer locking mechanism operational from an engaged position securing the outer attachment device to the inner attachment device and a disengaged position permitting the outer attachment device to move on the first tow member independent of the inner attachment device; a first distance member having a first end connected to the inner locking mechanism and a second end connected to the second tow member wherein the inner locking mechanism is operated to the disengaged position by a force applied across the first distance member toward the tow vessel; and a second distance member having a first end connected to the outer locking mechanism and a second end connected to the third tow member, wherein the outer attachment device is operated to the disengaged position in response to a force applied across the second distance member toward the tow vessel.
