According to these two links, Clementine was housed in HMB-1. It was flooded and placed under the Glomar Explorer.

Glomar Explorer was completed in 1973. The ship's interior contained a massive and highly secret hanger, with a 199 foot long "moon pool" - an open-water cutout, allowing the crew direct access to the water beneath the massive vessel. Along with Glomar Explorer, the Hughes Deep Ocean Mining Project constructed two additional components: a massive claw (dubbed "Clementine" by the crew of Glomar Explorer), intended to lift the 3000-ton hulk of K129 from the muck of the seabed, and the HMB-1 (Hughes Mining Barge 1), a huge submersible barge (actually a dry dock of sorts) designed to house the claw and the wreckage, once recovered. The HMB-1 would be carried in Glomar's interior hanger, and lowered into the water through the moon pool. This arrangement allowed the operation to take place completely hidden from the prying eyes of spy satellites, reconnaissance aircraft and Soviet trawlers.

Once HMB-1 was lowered into the water, Glomar Explorer would begin to assemble and spool out the 3.2 miles of tether attached to the massive claw, Clementine. The claw was to be lowered and raised so gradually that the round trip to the sea floor would take more than three days of travel. All told, the Glomar Explorer would spend more than a month on station executing its unique mission. Because it was nearly impossible to drop anchor in 17000 feet of water, Glomar Explorer utilized an elaborate and advance technique for remaining motionless on the sea. Fitted with automatically-controlled, rotating vectored thrusters which allowed for careful repositioning and movement compensation, Glomar Explorer accessed a then top secret set of global positioning satellites to navigate and position itself.
