Abstract
A connection is disclosed which is particularly applicable to subsea wellheads. A female receptacle end is provided on the wellhead which has connections on it to an umbilical or a flowline. The male end has an orientation lug for rough orientation. Once rough orientation is made, the male end is advanced into the female end and the shaft rotated by a remotely operated vehicle (ROV) for alignment of lugs with a detent. Once the lugs advance past the detent, they are rotated so that a segment of the shaft on the male end of the connection can no longer turn. Further rotational movements by the ROV on another portion of the shaft advances a plate which makes up the connection, either for the umbilical or the flowline.
