The Single Joint Elevators and the Link Tilt Assembly work
together to pick up the joint of Casing from the V-door.

12. © 2012 Tesco Corporation. All rights reserved.
When picked-up, the Link Tilts
and Single Joint Elevator are
centered with the CDS. The
joint is lowered so that the pin
end of the Casing is stabbed
into the stump.
The CDS is then lowered into
the joint of Casing, stopping
before the Stop Bumper.

The CDS Operator then engages the
actuator and the grapples will ramp out
and grip the ID of the casing.
Once the CDS is properly engaged inside
the casing, the CDS operator signals the
driller to engage the top drive to make up
the casing to the preset torque.
Once the connection is made, the CDS tool
takes the weight of the string and the slips
are released and the string is lowered into
the well.
While the string is being lowered the rig
pumps can be engaged to fill the casing,
and if desired, to circulate and reciprocate.

14. © 2012 Tesco Corporation. All rights reserved.
As the joint reaches the floor the single joint elevators can be
extended to receive the next joint of casing.
Once at floor level the slips are
set and the casing string is
released by the CDS.
(A design feature of the tool
prevents release of the casing
with weight on the grapples).

For wells with well bore
instability when they are drilled,
there is a very high probability
that the casing will be difficult to
run.
In such cases a reaming shoe
with a cutting structure can be
run on the casing to assist the
casing running system in rotating
and washing the casing down.
