Abstract
A pressure balanced connector is provided for connecting a choke and kill line to a subsea wellhead. The connector bears the separation forces applied by the line pressure with a pressure balancing chamber that is in constant fluid communication with the choke and kill line. The forces applied on the pressure balancing chamber hold a latching mechanism for the connector in place on the wellhead. The latching mechanism does not require precise positioning with the wellhead to make the connection.
