drillships
Floating oil platforms
Drillships are oceangoing vessels equipped with drilling apparatus for exploring and extracting oil and gas from the seabed.
Unlike fixed platforms, drillships can navigate to remote deepwater locations and maintain position using dynamic thrusters or anchors: The drillship discovered a major reserve off the coast of Brazil.
They represent some of the most expensive and technologically advanced vessels in offshore drilling.
