  • Patent number: 9057463
    Abstract: A subsea connector includes first and second tubular members, each having a forward end with an external first flange. A guide basket with an open forward end extends around the first tubular member. A fluid cylinder assembly moves the guide basket axially relative to the first tubular member between a rearward position and a forward position. Lock dogs are carried by the second tubular member. Each of the dogs has a first load shoulder and a second load shoulder and is mounted to a dog support. The dog support has a forward portion that contracts and expands radially relative to the second tubular member. While the guide basket is in the forward position, an interior of the guide basket engages outer sides of the dogs to retain the first and second load shoulders of the dogs in engagement with the first and second flanges.
