A pump for use in pumping hydraulic well control fluid expelled from a control device of a well, comprises means for accumulating such hydraulic well control fluid and means for using the pressure of hydraulic fluid supplied to the well to pump accumulated hydraulic well control fluid into a production flowline of the well.

Pumps

A subsea control module has a casing inside which there is at least one pair of electrodes, there being electronic means connected with the electrodes of the or each pair for monitoring at least one electrical characteristic between the electrodes as a result of a fluid to which the electrodes are exposed. This can include, for example, a change due to an ingress of seawater and/or an ingress of hydraulic fluid into the interior of the casing. The or each pair of electrodes include an array in which each electrode of the pair has finger portions interleaved with finger portions of the other electrode.

Monitoring of undesirable fluid ingress into subsea control modules

A subsea control module has a casing () inside which there is at least one pair of electrodes, there being electronic means (-) connected with the electrodes of the or each pair for monitoring at least one electrical characteristic between the electrodes as a result of a fluid to which the electrodes are exposed, the or each pair of electrodes comprising an array () in which each electrode of the pair has finger portions interleaved with finger portions of the other electrode.
