A wellhead port plug assembly includes a first plug body including connection elements allowing the first plug body to be sealingly and removably mounted in a port of a wellhead of a hydrocarbon well. The plug assembly includes a spool unit displaying an axial through-channel extending between a first end and a second end of the spool unit, which spool unit includes a first flange section arranged at the first end for sealingly mounting the spool unit to the wellhead aligning the through-channel with the port, and a second flange section arranged at the second end; a second plug body including connection elements allowing the second plug body to be sealingly and removably mounted in the through-channel; and a blind flange which is sealingly and removably mounted to the second flange section allowing the second plug body and the first plug body to be removed from the wellhead via the through-channel.

Wellhead port plug assembly

A tool for installation of units in connection with oil wells, comprising a housing () with an attachment device () for attachment to a well installation, a telescopic device () for extension of the tool, a torsional force transmission device () for rotation of an internal movable element () of the tool. The internal movable element () comprises a pressure face (), which in an operative condition is exposed to a well pressure and a counter-pressure face (), with a sealing arrangement () between the housing () and the internal movable element () provided between these pressure faces () and devices () which are arranged in such a manner that a pressure can be applied to the counter-pressure face.
