ABSTRACT OF THE DISCLOSURE A remotely operable connector having releasably connec- table male and female members. The male member sealingly engages the female member on connection. The female member houses radially moveable dogs which may be locked in con- necting engagement in a groove on the male connector by a lock sleeve longitudinally moveable over the dogs. The sleeve, which is biased to dogs locked position, moves to dogs unlocked position in response to pressure applied to a first inlet and may be retained in dogs locked position by continued application of pressure to a second inlet. The female connector houses a pressure lock which prevents movement of the lock sleeve from locked position on appli- cation of pressure to the first inlet, if there is pressure in the connector bore. The connector is unlocked for disconnect when there is no pressure in the connector bore and pressure is applied through the first inlet, moving the sleeve to dogs unlocked position. This connector is par- ticularly useful in a disclosed underwater well wireline servicing system, as as a wellhead connector or lubricator section connector. The well servicing system provides wire- line well servicing of underwater wells without pollution of surrounding water and for emergency disconnect from the under water wellhead for quick floating service vessel remo- val.
