The ships flying the United Kingdom flag were built at the South Korean shipyard Samsung Heavy Industries in Geoje . They belong to different shipowners, but are all owned by the British company Stena Drilling Ltd. operated, which in the Scottish Aberdeen is established.
With the ability to drill up to 10,000 feet (about 3,050 m) deep water, the ships in the series are among the most powerful drilling ships in the world.
