Jacket Supported Offshore Rig is one of the rig design concepts for shallow water environments.

• Steel Jacket can be tailored to water depth.
• Rig design is independent of water depth.
• Environment impact is low.
• Jacket could be designed to withstand ice loads.
• Installation and removal may be difficult as barge and crane are required to install and pile jacket.
• Rig can be skidded, so multiple wells can be drilled from single jacket for appraisal or development
•  Jacket costs expected to be moderate and largely unaffected by water depths
• Modular or modified Land Rig can be used.
