Offshore Oil Rig Types
Semi Submersible: This is a offshore oil rig that
has a floating drill unit that includes columns and pontoons
that if flooded with water will cause the pontoons to
submerge to a depth that is predetermined. It moves with
waves and sits low on the water with most of the structure
underneath the water. This is the type of drilling rig
that is being used for the North Sea and west Scotland
wells. Now with a leap in technology depths of up to 5000
feet can be achieved safely and easily. This type of rig
platform will drill a hole in the seabed and can be quickly
moved to new locations.

you have any questions on offshore oil rig jobs or general
employment in the industry, please don't hesitate to get in touch with us.
Platform: Formed from a combination of steel and concrete
this offshore oil rig structure sits on the seabed. This immobile
platform is designed to help drill the wells further into
the ground and also to help produce greater levels of hydrocarbons.
Jack up: A jack up is a mobile rig that instead of
floating over the drill area like a semi submersible, this
has a long leg that can lower or raise the rig in and out
of the water. This rig type can only operate to 500 feet in
the depth of water. Used frequently in the North Sea, as the
areas there are not too deep for its use.
Drill ship: This structure is designed in a ship shape
as a drilling vessel. This rig does not need tugboats to keep
in place unlike Jackup and Semi submersible. This offshore
oil rig can drill in very deep waters.
Flotels: A flotel is made up of a semi submersible
that has been changed to suit a new purpose. It can be attached
to a semi submersible and give extra accommodation for added
employees. Also provides a place for catering and leisure
activities.
Floating Production & Storage Units: This
structure can be attached to the seabed and produce a place for the storage of
oil until a tanker may take the oil to land. Can be made from units or tankers
and also semi submersibles.
