    摘要： guide is provided for forming a pipe connection from a sub sea wellhead 3 back to a surface platform which may not be in perfect alignment. The guide comprises a guide post 1 and a cable 4 on which it may be lowered through a pipe 6 to the wellhead. The guide post 1 has a radially expandable mandrel 2 for temporary rigid attachment in the wellhead and an elongate portion 1A having a rotatable sleeve 12 over which the pipe 6 may be lowered into engagement with the wellhead and rotation to form the connection desired. The rotation of the pipe 6 to form the connection is possible because of the sleeve 12.
