摘要： 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.
