Abstract
A locating and locking mandrel and associated nipple provide for positioning an item of equipment in large bore and high weight conditions. In a described embodiment, a locating and locking mandrel includes at least one collect which is configured to cooperatively engage an internal profile of a nipple. The collect is capable of supporting the weight of the item of equipment until at least one locking member of the mandrel is engaged with another internal profile of the nipple. A seal of the mandrel is received in a seal bore of the nipple prior to insertion of the locating member or locking member into the seal bore, thereby preventing damage to the seal bore.
