ABSTRACT:
A submergible pump is suspended from a suspension head and lowered into an underwater well. The pump is lowered through the bore of a spool at the wellhead, and the suspension head is supported on a shoulder in the spool. A contact region of the bore has a first set of contacts engageable with corresponding contacts of a second set on the suspension head. Well fluid and other contaminants are flushed from the contact region by a cleaning fluid dispensed from passages in the suspension head. A dielectric fluid is then similarly dispensed to the contact region. Locking lugs lock the suspension head in the spool, and seals exclude well fluid from the contact region. The cleaning fluid and the dielectric fluid may be supplied from a remote source, such as a vehicle employed in lowering the pump and suspension head.
