Weak Link Bails
It is a well-known industry challenge to operate
semi submercibel drilling rigs safely at all times
during completion, well testing, well interven-
tion and workover riser (WOR) operations. Higher
pressure rated WOR systems combined with all
year round operations in the harsh environments
of the world have increased the probability for
catastrophic events and equipment damage during
well testing and workover operations.
This has been recognised by the International Standards Organisation who have written ISO
13628-7 Chp 6.7.1 which states that “A safety joint or weak link shall be designed to fail or break
under specified loads”. The weak link bails have been designed to do exactly that during any fail-
ure to the compensator whether mechanical or human.
Deepwater drilling
As the demand for oil increases and with the
developments in technology, the requirement to
be able to extract oil from deeper and harsher
environments continues to grow. The Weak Link
Bails is ideally suited for this environment with the
additional protection offered to the riser and other
expensive equipment. As the water depth for drill-
ing increases, so does the risk to the environment
and potential negative publicity for the offshore
industry.
Weak Link Bail offers:
- Protection to personnel
- Protection to the riser
- Protection from any unforeseen forces that
may be applied to the rig
- Environmental protection
- Protection from any mechanical lock up - if
the rig experiences increased loading, the
auto matic shearing of the Weak Link Bolt
will allow increased stroke in the bail, so no
load is transferred into the riser, well head
or derrick.
- No environmental spillage is caused by the
emergency disconnection of the riser
- No riser or other expensive equipment
damage
