Tethered BOP technology enables DP rigs to drill in shallow water

Shallow-water wells can now be drilled using dynamically positioned (DP) deepwater rigs, if critical safety challenges are addressed. Recent drilling programs demonstrate that a properly designed tethered blowout preventer (TBOP) system allows a DP unit to drill new and workover wells or perform P&A operations in 500-ft (152-m) to 2,000-ft (610-m) water depths.
