A drillship is a merchant vessel designed for use in exploratory offshore drilling of new oil and gas wells or for scientific drilling purposes. In most recent years, the vessels are used in deepwater and ultra-deepwater applications, equipped with the latest and most advanced dynamic positioning systems. A drill ship is a particular type of mobile offshore drilling unit (MODU) that is composed of a ship with a drilling rig on its top deck. These ships can go right to the drill site. Deepwater exploration and drilling have shown a remarkable increase over the past few years.
