Quick Summary

A drillship is a vessel equipped for drilling into the ocean floor, primarily for oil exploration. These oceangoing ships feature a derrick mounted centrally, positioned over an opening for the drilling operations.12

Originally, drillships were held in place by multiple anchors. However, modern drillships utilize dynamic positioning systems, allowing them to operate effectively even in severe weather conditions and heavy seas. While primarily used for exploratory drilling before significant offshore production commitments are made, drillships are a crucial component of deepwater petroleum exploration.2
