Dual shear ram requirements
Consideration should be given to a dual shear/blind ram facility when operating without
riser margin as is typical in some deepwater locations. Also in the event of an un planned
disconnect without a riser margin, a contingency sealing mechanism in addition to the
shear rams should be considered. To increase contingency for running casing when
permeable formations are exposed and to reduce the likelihood of running a drilling liner.
It is also preferable to have rams with a high shear capacity |
