Houston TX: A recent detailed analysis together with Kongsberg has shown that a 9-second EDS results in dramatically improved DP operability and can enable Shallow Water DP Ops. The 9 second EDS is enabled by the K-BOS, which can shear anything and seal instantly, regardless of the situation and without need for space out or other provisions.

A K-BOS enabled dynamically positioned (DP) drilling rig can achieve a 9-second emergency disconnect sequence (EDS) compared to typical EDS times that can be as long as 70 seconds. This results in enhanced DP Operability and enables DP rigs to reduce time waiting on weather among other operational gains. A 9-second EDS also enables rigs to operate in DP mode in shallow water depths of 500 ft or shallower safely and reliably. This is according to a recent detailed simulation and sensitivity study performed by Kongsberg, the industry leading provider of DP systems.

The benefits for a 9-second EDS identified by the study include:

  • Improved watch circle/time to disconnect
  • Enable safe and reliable DP Operations in shallow water depths less than 500 ft
  • Reduced stress/bending moment in foundation
  • Single function EDS (shear/seal) and DMAS (shear/seal)
  • Low-cost alternative to anchored rig, pre-installed mooring system (anchorless operations in crowded subsea areas)
  • Lower cost alternative to BOP tethering systems

Summary results of the study have been provided below. Having reviewed the study with super-major deep-water E&P operators, the projected operational gains enabled by the K-BOS for DP drilling rigs are expected to be in a range of 6% to 12% in a given year per rig.

In addition to this improved performance for DP rigs in deep water, the study highlights an opportunity to utilize DP rigs in shallow water and in some harsh environments instead of moored rigs.

Further analysis provides that this can result in 10% to 14% reductions in overall spread operating costs well by well and, in cases where a particular campaign requires multiple rig moves, the overall spread efficiency results in a significant reduction in fuel consumption and a reduction in CO2 emissions.

North Sea Study Results Summary:

  • 30% to 50% more time to react Vs 32 second EDS vs 0m RWC w/ 70 sec EDS
  • NS Winter Weather and West of Shetland was included in “Average Weather Conditions”

GOM Study Results Summary:

  • 2 to 3 x more time to react @ 350ft water depth
  • >2 x more time to react @ 1,000ft water depth
  • Study excluded hurricanes but included a 10-yr loop current load case
