Dual axes connection device
A dual axes connection device for use with a mooring line, a line guide and pulling means for connecting a floating body and a fixed body is provided. The connecting device comprises a dual axes hinge unit, with orthogonal rotational axes x and y, comprising means for fastening the unit to the floating or fixed body, a connecting link fastened to the hinge unit comprising two parallel arms, a funnel connected to the two parallel arms enveloping the mooring line, and locking means for locking the mooring line to the funnel. The mooring line, the line guide and connection device are positioned in one plane.
1. A dual axes connection device for use with a mooring line, a guide structure and pulling means for connecting a floating body and a fixed body, wherein the guide structure is a fixed guide structure on the floating body, and wherein the mooring line, the guide structure and dual axes connection device are positioned in one plane and wherein the dual axes connecting device comprises:
a dual axes hinge unit, with orthogonal rotational axes x and y, comprising means for fastening the dual axes hinge unit to the floating or the fixed body, a connecting link fastened to the dual axes hinge unit, a funnel enveloping the mooring line, and locking means for locking the mooring line to the funnel, the funnel having an inner end, wherein the connecting link comprises two parallel arms each having outer ends, and the funnel being rotationally connected to the two parallel arms by trunnions and mating formations in the outer ends of the two arms, wherein the locking means are two hinged identical mirrored chain locking components fitting into mating formations at the inner end of the funnel and having a distance between the two hinged identical mirrored chain locking components preventing the mooring line from being pulled out of the dual axes connection device in an opposite direction of a main pull-direction.
2. The dual axes connection device according to claim 1 , wherein the mooring line is a chain, wire or rope.
3. The dual axes connection device according to claim 1 , wherein the locking means are pre-tensioned and self-engaging when tension of a second line section of the mooring line is relieved.
4. The dual axes connection device according to claim 1 , wherein the connecting link is connected to the dual axes hinge unit with rotable means such that the funnel will follow the direction of the mooring line independent of the connecting link.
5. The dual axes connection device according to claim 1 , further comprising a first line section of the mooring line extending between a fixed body on a seafloor and the connection device attached to a floating body, or vice versa, and a second section of the mooring line extending between the dual axes connection device and pulling means, wherein the dual axes connection device comprises a fixing device comprising: a pulling side and a fixed line side each with fastening means for the first and second sections of the mooring line respectively; the locking means for locking the fixing device to the funnel.
6. The dual axes connection device according to claim 5 wherein the funnel and the fixing device each have mating conical surfaces.
7. A method of connection a dual axes connection device to a floating body, the method comprising:
connecting the dual axis hinge unit of the dual axes connection device of claim 1 to the floating body, wherein a pulling means for pulling the mooring line is onboard the floating body, and a guide structure for guiding the mooring line is fixed to the floating body.
8. A method for connection a dual axes connection device to a mooring anchor, the method comprising:
connecting the dual axis hinge unit of the dual axes connection device of claim 1 to a mooring anchor, wherein a pulling means for pulling the mooring line is onboard an auxiliary vessel or temporarily attached to the mooring anchor, and a guide structure for guiding the mooring line is fixed to the mooring anchor.
