Abstract
A single or multi-bowl wellhead may be positioned in a diverter housing over the wellbore. Protrusions on the wellhead may be installed after the diverter housing is removed. The wellhead accommodates the direct connection of hydraulic lines to a hanger seated therein. An overshot running tool protects the wellhead during placement and certain operations.
