A running tool configured to insert and set a retrievable subsea unit (RSU) into a subsea tree, said running tool comprising:
- a frame comprising a lock configured to lock and unlock the running tool with respect to the subsea tree, a drive configured to lower or lift the RSU with respect to an accommodation space of the subsea tree, and a module lock configured to releasably lock the RSU to the drive, wherein the lock comprises a rod shaft, at least two connection rods, and at least two hooks, wherein each of the at least two connection rods comprises a first end pivotally coupled to the rod shaft and a second end pivotally coupled to at least one hook of the at least two hooks, and wherein the lock is configured to move between a locking position in which the at least two hooks are in a first position that enables the at least two hooks to engage a subsea structure to lock the running tool with respect to the subsea tree and a release position in which the at least two hooks are in a second position that enables the running tool to move relative to the subsea tree.
A running tool configured to insert and set a retrievable subsea unit (RSU) into a subsea tree, said running tool comprising:
- a frame supporting a lock configured to lock and unlock the running tool with respect to the subsea tree, wherein the lock comprises a rod shaft, at least two connecting rods, and at least two hooks, wherein each of the at least two connecting rods comprises a first end pivotally coupled to the rod shaft and a second end pivotally coupled to at least one hook of the at least two hooks, and wherein the lock is configured to move between a locking position in which the at least two hooks are in a first position that enables the at least two hooks to engage a subsea structure to lock the running tool with respect to the subsea tree and a release position in which the at least two hooks are in a second position that enables the running tool to move relative to the subsea tree.
A running tool configured to insert and set a retrievable subsea unit (RSU) into a subsea tree, said running tool comprising:
- a drive configured to lower or lift the RSU with respect to an accommodation space of the subsea tree;
- and
- a module lock configured to releasably lock the RSU to the drive;
- wherein the module lock comprises a mandrel holder that defines an opening configured to receive and support a mandrel coupled to the RSU, a lock plate configured to move through the opening between a first position in which the lock plate enables insertion of the mandrel coupled to the RSU into the opening defined by the mandrel holder and a second position in which the lock plate blocks withdrawal of the mandrel from the opening defined by the mandrel holder.
A running tool configured to insert and set a retrievable subsea unit (RSU) into a subsea tree, said running tool comprising:
- a frame comprising a lock configured to lock and unlock the running tool with respect to the subsea tree, a drive configured to lower or lift the RSU with respect to an accommodation space of the subsea tree, and a module lock configured to releasably lock the RSU to the drive, wherein the frame comprises:
- an upper frame comprising at least one of the lock, the drive, and the module lock;
- and
- a lower frame comprising a RSU accommodation space configured to receive the RSU.
