Flex joints
July 2012Slide 24
■ Lower flex joints are used to allow
angular misalignment between the
riser and the BOP stack, thereby
reducing the bending moment on
the riser.
■ Upper flex joints are used at the top
of the riser to allow for the motion of
the rig.
■ Intermediate flex joints can be
installed at an intermediate level in
the riser string below the telescopic
joint to reduce stresses in the riser.Upper Flex JointLower Flex Joint

Tension ring
July 2012 Drilling risersSlide 30
■ The riser tension ring is attached
to the tiser telescopic joint
■ Provides the structural interface
between the rig tensioner system
and the marine riser
■ The tensile load to support the
riser is transmitted from the rig
tensioners through the tension
ring to the outer barrel of the
telescopic joint
■ The tension ring come as solid,
hinged or split

Spacer joint
July 2012 Drilling risersSlide 32
■ Used to bridge the distance between the telescopic joint and diverter and allow for
correct space out of the telescopic joint

Fill-up valve
July 2012 Drilling risersSlide 33
■ Allows the Riser to fill with water to prevent the collapse of the riser string due to
pressure differences by sea water pressing on the exterior of the riser string if drilling
mud exits the riser during operation.

Bay handling tool
July 2012 Drilling risersSlide 34
■ Moves riser joints in and out of the riser
bay vertical storage area
■ Is designed to hold the load of one riser
joint at a time in vertical position only

Test tool
July 2012 Drilling risersSlide 36
Peripheral line seals are tested as the
riser joints are made up during tripping of
the riser
The peripheral lines boxes and pin
connections must be tested when
tripping the riser to insure pressure
integrity of the lines

Summary in brief
July 2012 Drilling risersSlide 70
■ This breech locking mechanism is designed to offer the operators a means of saving
substantial make up time, as compared to a conventional flanged-type riser joint, with
total safety when drilling in deep waters
■ Average make-up time to make up the pin/box connection of the CLIP riser is 11
seconds. The two connectors are stabbed together and the locking ring is rotated 45
degrees
■ Most secure connection: fully opened or closed positions only
■ Key safety feature: minimizes dropped object as no bolts are used to make up theconnection between the two joints
■ Field experience has shown that six to eight joints can be run per hour
■ No threading, bolting or preloading
■ Easy stabbing even with misalignment
Operational time savings and safety enables financial benefits
