Abstract
In combination, the loose tube flying lead includes: a) a pair of improved cobra head assemblies, each being able to receive a variety of different stab-plates with minimal modification; b) a pair of bend limiters, one extending from each cobra head assembly and c) an elongate bundle of non-constrained interior conduits surrounded by an over-hose, the over-hose being connected to each bend limiter. The over-hose may rotate independently of the bend limiters and the cobra head assemblies.

A flying lead assembly, comprising:
- a) an elongate bundle comprising:
- a plurality of non-constrained interior conduits;
- an elongate load bearing over-hose having a first end and a second end;
- and
- a pair of load bearing over-hose connectors, one affixed to the first end and the other affixed to the second end of the over-hose, each over-hose connector forming a radial flange on a free end;
- b) a pair of cobra head assemblies, having:
- a load bearing frame having an interface element on one end and a load bearing bend limiter connector on the other end;
- a load bearing interior conduit termination assembly mounted on the universal frame between the interface element and the bend limiter termination assembly to secure each non-constrained interior conduit to the frame;
- and
- a buoyancy module surrounding at least a portion of the cobra head assembly, the float forming a storage container for a flexible conduit with one end terminated to a connector;
- and
- a first ROV connector assembly, having an elongate flexible conduit, one end of the flexible conduit connected to a ROV connector and the other end connected to a first interior conduit;
- and
- c) a pair of elongate, flexible load bearing bend limiter assemblies, each engaged on one end to the bend limiter connector of the cobra head assembly and on the other end to the radial flange of the over-hose terminal connector to rotationally and axially secure each cobra head assembly to the over-hose and allow rotational freedom between the cobra head assemblies, the bend limiter assemblies and the over-hose.
