Weak Link Bails The answer to ISO 13628-7 Chp 6.7.1 compliance Risk reduction for life, environment, reputation and expensive equipment.
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 intervention 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.
Performance The precision setting of the Weak Link Bolt allows for the stroke of the Weak Link Bails to be extended 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.
References ISO 13628-7. Weak link safety joint chp. 6.7.1. The C/WO riser system in use shall be designed with adequate safety joint / weak link to prevent damage to the well barriers in case of accidental loads in the C/WO riser system. APOS. Statoil Control System, specify that a weak link shall be included in workover riser systems on underwater installation work with semi sub rigs.
