Abstract
A restrictor device is used on a cable to protect the cable from excessive bending. The restrictor device includes two or more restrictor members having a helix shape extending along a longitudinal axis X; and fasteners that connect the two or more restrictor members to each other to form the restrictor device. At least one property of the two or more restrictor members is selected such that a bending portion of the restrictor device moves along the restrictor device when a magnitude of a force applied to the restrictor device changes.
Claims17
A restrictor device for a cable, the restrictor device comprising:
- two or more restrictor members having a helix shape extending along a longitudinal axis X;
- each restrictor member having a head portion, a body portion, and a tail portion;
- and
- the head portions of the two or more restrictor members and the tail portions of the two or more restrictor members being connected to each other, respectively, by fasteners to form the restrictor device,
- wherein at least one property of the two or more restrictor members is selected such that a bending portion of the restrictor device moves along the restrictor device when a magnitude of a force applied to the restrictor device changes.
A seismic acquisition system comprising:
- a spread element configured to collect seismic data;
- a cable connected to the spread element;
- and
- a restrictor device connected to the spread element and fully encircling the cable,
- wherein the restrictor device is configured to protect the cable from excess bending and at least one property of the restrictor device is selected such that a bending portion moves along the restrictor device when a force applied to the restrictor device changes its magnitude,
- wherein the restrictor device includes two or more restrictor members, each restrictor member having a head portion, a body portion, and a tail portion, and
- wherein the head portions of the two or more restrictor members and the tail portions of the two or more restrictor members are connected to each other, respectively, by fasteners to form the restrictor device, and
- the two or more restrictor members have a helix shape extending along a longitudinal axis X.
