Abstract

A single drilling ship (10) may be equipped with two drilling centers, each capable of running risers (24;40). Each drilling center has a set of tubulars stored for use in association with that drilling center, those tubulars including risers. However, the risers for one drilling center are of a smaller diameter than the risers for the other drilling center. In the event that a main drilling center (14) drilled well fails, a relief well can then be drilled from the same ship using a secondary drilling center (12). (Figure 1)
