Abstract
A segmented-foil divertor for marine towed application, such as marine seismic exploration, having a plurality of longitudinally stackable foil segments with an internal conduit extending along the span of each segment to receive a cable passing therethrough.
Claims26
A collapsible segmented-foil divertor comprising
- a plurality of longitudinally stackable foil segments arranged in a stack with opposing ends, wherein each foil segment defines a foil cross-section, a leading edge, a trailing edge, a span, and an internal conduit extending along the span positioned rearward of the leading edge of the foil segment;
- a cable passing through the internal conduits of each of the plurality of foil segments and having a respective free end extending outwardly from each opposing end of the stack;
- a triangular-like bridle having an apex, sides, and a base, wherein:
- the apex is defined by a connection point between the bridle and rigging trailing behind a towing vessel;
- the sides are defined by a first bridle line attached between the connection point and one free end of the cable and a second bridle line extending between the connection point and the other free end of the cable;
- and
- the base is defined by the cable;
- and
- one or more intermediate bridle lines extending between the connection point and the cable.

A method of positioning towed equipment behind a towing vessel, comprising:
- passing a cable through an internal conduit in each of a plurality of longitudinally stackable foil segments each having a foil cross-section, a leading edge, a trailing edge, a span, and an internal conduit extending along the span positioned rearward of the leading edge of the foil segment to receive a cable passing therethrough;
- attaching a triangular-like bridle having an apex, sides, and a base, wherein:
- the apex is defined by a connection point between the bridle and rigging on the towing vessel;
- the sides are defined by a first bridle line attached between the connection point and one free end of the cable and a second bridle line extending between the connection point and the other free end of the cable;
- and
- the base is defined by the cable and one or more intermediate bridle lines extending between the connection point and the cable;
- and
- towing the plurality of foil segments through the water behind the towing vessel.
