| Zusammenfassung: | A protective cap (12) can be run onto and retrieved from a subsea wellhead (10) from a floating service vessel. Slidably mounted shear pins (32) in the cylindrical wall (14) of the protective cap (12) allow the cap to be attached by a downward push. Retrieval of the protective cap (12) involves an overpull on the drill string that is sufficient to shear the pins (32) in the cylindrical wall (14). |
