Abstract
The method according to the invention comprises providing a flexible line (18) and a bend limiter axially immobilized around the flexible line (18) by a releasable immobilizing mechanism (46). It includes partially inserting the flexible line (18) through a hollow rigid member (40), immobilizing the bend limiter on the hollow rigid member (40), and deactivating the releasable immobilizing mechanism (46). The releasable immobilizing mechanism (46) is deactivated independently of the movement of the flexible line (18) relative to the bend limiter.
Claims14
A method for connecting a flexible line to a structure of a fluid exploitation installation, comprising the following steps:
- providing a flexible line and a bend limiter axially immobilized around the flexible line by a releasable immobilizing mechanism;
- partially inserting the flexible line through a hollow rigid member secured to the structure;
- immobilizing the bend limiter on the hollow rigid member;
- deactivating the releasable immobilizing mechanism;
- moving the flexible line relative to the bend limiter in the hollow rigid member, the bend limiter remaining substantially axially stationary relative to the hollow rigid member;
- wherein the releasable immobilizing mechanism is deactivated independently of the movement of the flexible line with respect to the bend limiter, and in that the releasable immobilizing mechanism includes a retaining member secured to one of the flexible line and the bend limiter and a moving engaging member mounted on the other of the bend limiter and the flexible line, the engaging assembly being a segmented nut.
A connecting device, designed to be mounted on a structure of a fluid exploitation installation, including:
- a flexible line;
- a hollow rigid member designed to be fastened on the structure, the flexible line being designed to be engaged through the hollow rigid member;
- a bend limiter engaged around the flexible line, the bend limiter being designed to be axially immobilized on the hollow rigid member;
- a releasable axial immobilizing mechanism for the flexible line on the bend limiter;
- wherein the releasable immobilizing mechanism is capable of being deactivated independently of the movement of the flexible line relative to the bend limiter, and in that the releasable immobilizing mechanism includes a retaining member secured to one of the flexible line and the bend limiter and an engaging assembly mounted on the other of the bend limiter and the flexible line, the engaging assembly being a segmented nut.
