Connector for releasable connection between an anchorage in the form of a female part arranged on a floating means and a male part formed at the end of a retrievable umbilical

1. A connector for releasable connection between an anchoring in the form of a female part ( 1 ) arranged on a floating means and a male part ( 2 ) formed at the end of a retrievable umbilical ( 3 ) provided with a bend stiffener ( 4 ), which male part ( 2 ) comprises a mandrel body ( 5 ) having a pulling head ( 6 ) for connection to a pulling means at one end and the umbilical ( 3 ) at the other end, a sleeve formed body ( 7 ) that is fixed to the mandrel body ( 5 ) by shearable elements ( 8 ), and the bend stiffener ( 4 ) is fixed directly to the sleeve formed body ( 7 ), said sleeve formed body ( 7 ) being designed for abutment against and parking together with the bend stiffener ( 4 ) within the female part ( 1 ) while the remaining portion of the male part ( 2 ) including the umbilical ( 3 ), is designed to be pulled further up through the female part ( 1 ) for connection and fluid communication on the floating means, characterized in that the sleeve formed body ( 7 ) in the leading end thereof comprises a number of resilient collar fingers ( 7 a ) for cooperation with the female part ( 1 ) and axial fixation of the sleeve formed body ( 7 ) and the bend stiffener ( 4 ) to the female part ( 1 ).

2. The connector according to claim 1 , characterized in that the mandrel body ( 5 ) comprises a shoulder ( 5 a ) releasably provided on the pulling head ( 6 ).

3. The connector according to claim 2 , characterized in that the releasable shoulder ( 5 a ) is made up by two halves, alternatively a number of segments.

4. The connector according to claim 2 , characterized in that said shoulder ( 5 a ) on the mandrel body ( 5 ) is designed to co-operate with the resilient collar fingers ( 7 a ) by a possible later release of the sleeve formed body ( 7 ) and the bend stiffener ( 4 ) from the female part ( 1 ).

5. The connector according to claim 1 , characterized in that the sleeve formed body ( 7 ) comprises an external shoulder ( 7 b ) for centering within the female part ( 1 ).

6. The connector according to claim 1 , characterized in that the mandrel body ( 5 ) in its lower end comprises arresting means ( 9 ), which arresting means ( 9 ) is able to prevent that the sleeve formed body ( 7 ) including the bend stiffener ( 4 ) rush down the umbilical ( 3 ) during a possible release according to claim 5 .

7. The connector according to claim 6 , characterized in that each arresting means ( 9 ) is spring loaded and able to pass an obstacle in one direction, but not in opposite direction.

8. The connector according to claim 1 , characterized in that each shearable element ( 8 ) is arranged radially through the wall of the sleeve formed body ( 7 ).

9. The connector according to claim 8 , characterized in that each shearable element ( 8 ) is radially displaceable through said wall of the sleeve formed body ( 7 ) and that each shearable element ( 8 ) has a weakening point that is exposed to the shearable forces when the sleeve formed body ( 7 ) has reached predetermined location within the female part ( 1 ).
