Summary
An investigation examines the discharge of 128 barrels of synthetic-base mud during casing running on ENSCO 8502. A ruptured air hose caused pressure loss at the telescopic joint packer. The report identifies a disabled pressure alarm and manually operated hydraulic backup; engaging the secondary packer stopped the losses.
