Abstract
A guide is provided for forming a pipe connection from a sub sea wellhead back to a surface platform which may not be in perfect alignment. The guide comprises a guide post and a cable on which it may be lowered through a pipe to the wellhead. The guide post has a radially expandable mandrel for temporary rigid attachment in the wellhead and an elongate portion having a rotatable sleeve over which the pipe may be lowered into engagement with the wellhead and rotation to form the connection desired. The rotation of the pipe to form the connection is possible because of the sleeve.
