Land rig on artificial island (shallow water)
Land rig on artificial island is one of the drilling rig concepts for offshore drilling in shallow water environments.
1. Water depth range: 0-10m. Costs rise significantly with water depth and distance from shore.
2. The environmental impact for marine life is potentially high. Island would disappear, with time, due to wave and ice effects. sheet piling used for retention it would need to be removed for island to dissipate.
3. Concept is particularly suitable for ice, but ice scour and ice rubble . . .
