Semi-submersible JBF 14000

The in-house designed JBF 14000 is a self propelled semi-submersible drilling unit with DP-3 classification. By fully integrating the designs of the equipment and vessel, its displacement is low in relation to her operational capacities and compared to existing rig designs. The JBF 14000 is suitable for worldwide drilling operations - conventional drilling, expandable drilling, coiled tubing - and field development - installation of subsea equipment, light and heavy work-over, deepwater hoisting, J-lay pipelay(optional).


The design permits drilling operations up to 14,000ft waterdepth. Total drilling depth capacity is in excess of 12,190m (40,000ft) measured from sea level. Vertical storage of risers will be done in the columns. 

 

The rig does not use a substructure which frees up deck space and lowers the centre of gravity.

 

The deck box contains four major sections: power generation located at the unit's aft end, mud mixing, treatment and pumping section located forward of the power generation plant, drilling section located in the centre, accommodation section located at the forward end of the unit.

 

 


Features

  • Large usable deck space: deckbox dimensions: length 91.2m, width 69.6m

  • Total usable deck area minimal 4,300sq m (46,300sq ft)

  • Drill floor flush with main deck (no elevated substructure)

  • Offline standbuilding capability

  • Drilling mast with 2,400 kips hoist on drilling side and aux side

  • Closed box structure of Dual Drilling Tower (no dropped objects)

  • Fully automated pipe handling

  • Open drill floors with unrestricted access from three sides, e.g. no V-door limitations

  • Double setback drums, four pipe rackers and two pipe feeders

  • Dual drawworks -> no slip-cut procedure needed

  • Active/passive heave compensation on the main well centre hoisting system

  • Use of splittable blocks for increased hoisting efficiency and speeds

  • Variable deck load of minimal 10,000mt (including 4,200mt risers in the columns)

  • Vertical riser storage in columns (21 inch riser)

  • Riser tensioner system with 8 riser tensioner sets. Two sets can be out of operations whilst the required tension in the riser column is maintained 

  • Riser column can be skidded from auxiliary well centre to main well centre under derrick 

  • DP-3, four engine rooms, eight thrusters, eight separated switchboard rooms

  • No bracing between pontoons
