Scan Tech Weak Link Bails - Manual (Page 3)

Performance
The precision setting of the Weak Link Bolt allows
for the stroke of the Weak Link Bails to be extend-
ed at a specific load. At the set load the Weak Link
Bolt will shear allowing the stroke of the Weak Link
Bails to increase – offering overload protection to
all components in the riser, well head and derrick.
- Weak Link Bail protects the rig in instances of surge, mechanical failure or
human error causing overloading of the riser or other expensive equipment
- Dramatically reduces the risk of uncontrolled spillage into the environment
- The increased stroke allows the rig operator to regain control without having to
disconnect the riser and risk leakage into the environment
- Designed topside for simplicity of use and ease of resetting after any incident,
avoiding expensive underwater operations.
Protection
While complying with ISO 13628-7, the weak link
system is specifically designed and manufactured
to minimise potential risks from compensator
failure or misuse. This avoids damage to the der-
rick, drilling rigs, travelling assembly and load path
equipment.
Disadvantages of not using Weak Link Bails
- Injuries or loss of crew
- Falling objects from potential overload
- Damage to the riser and other pressure
controlled equipment
- Undesirable spill to sea
- Potential damage to company reputation
Training
By utilising our on land rig in Stavanger this will allow training for the crew prior to the weak
link being installed on the offshore rig. This facility allows the weak link to be used in all modes
including the breaking of a link and the resetting of the Weak Link Bail. Taking advantage of this
training facility, will ensure that the rigs crews are able to fully utilise the efficiency saving of-
fered by the Weak Link Bails during actual production operations.
