Abstract: The invention relates to the checking of pressure in various void or cavities of a wellhead or Xmas tree of an active hydrocarbon well. Pressure sensing plugs (51) are provided at various points in the wellhead/Xmas tree (50). Each plug incudes a pressure transducer (39) and associated electronics allowing the pressure to be read by a hand held reader device. Alternatively, the plugs may include a radio transmitter for transmitting sensed data to a monitoring system via a wife network or similar to a central control room on a hydrocarbon producing platform. In this way, the pressure at the various point in the wellhead/Xmas tree may be checked without exposing the cavity or void.
