RIG SELECTION CRITERIARIG SELECTION CRITERIA
•• Location of drilling activity.•• Depth of water, seabed features & lateral
force at location for offshore drilling.•• Deck requirements.•• Size of field and location of wells.•• Transport of oil requirements.•• Type of drilling i.e. active site drilling,
‘wildcat’ well drilling, scientific drilling.

TYPES OF FIXED PLATFORMSTYPES OF FIXED PLATFORMS
•• Conventional fixed platforms•• Compliant towers•• Tension leg platform •• Seastar
CONVENTIONAL FIXED PLATFORMSCONVENTIONAL FIXED PLATFORMS
CONVENTIONAL FIXED PLATFORMSCONVENTIONAL FIXED PLATFORMS
•• Built on concrete / steel legs anchored onto seabed.
•• Deck with drilling rigs, production facilities and crew quarters
•• Structures used : steel jacket, floating concrete & concrete floating steel
•• Economically viable for installation in water depths up to 520m.
COMPLIANT TOWERSCOMPLIANT TOWERS
COMPLIANT TOWERSCOMPLIANT TOWERS
•• Made of narrow, flexible towers with piling foundation.
•• Support conventional deck for drilling and production operations.
•• Can sustain huge lateral forces and deflections.
•• Used in waters with 450-900m depth.
TENSION LEG PLATFORMSTENSION LEG PLATFORMS
TENSION LEG PLATFORMSTENSION LEG PLATFORMS
•• Made of floating rigs held by vertical, tensioned tendons.
•• Tension legs secured on seabed using pile-secured templates.
•• Eliminate vertical movements to the structure.
•• Used in waters of up to 2,000m depth.
SEASTARSEASTAR
SEASTARSEASTAR
•• ‘Mini Tension Leg Platforms (TLP)’• Cost less than normal TLP.•• Can be used as utility, satellite or early
production platforms for deepwater discoveries.
•• Deployed in waters between 200 to 1,100m.

•• Among the largest platforms in use.• Consist of large cylinders supporting
fixed rig platform.•• Cylinders are tethered by cables and
lines to seafloor.•• Cylinders stabilize platform and allow
movement to absorb hurricane impacts.

FLOATING PRODUCTION SYSTEMSFLOATING PRODUCTION SYSTEMS
•• Large vessels that can take, process and / or store oil & gas.
•• Moored to locations over long periods.•• Main systems : FPSO (floating
production, storage & offloading), FSO (floating storage & offloading) & FSU (floating storage unit).
SUBSEA SYSTEMSSUBSEA SYSTEMS
SUBSEA SYSTEMSSUBSEA SYSTEMS
•• Used in wells located on the seafloor to transport extracts via riser / pipelines to existing production platform.
•• Moveable rigs are used to drill wells, allowing for a platform to serve many wells over large area.
•• Used in waters up to 2,100m deep.
SEMI SUBMERSIBLESSEMI SUBMERSIBLES
SEMI SUBMERSIBLESSEMI SUBMERSIBLES
•• Mobile structures, some with own locomotion.
•• Can be ballasted up or down by adjusting flooding of buoyancy tank.
•• Anchored by cables during drilling operations or dynamic positioning.
•• Provide excellent stability in deep, rough waters between 180-1,800m.
SUBMERSIBLESSUBMERSIBLES

•• Look like ordinary ships but with derricks drilling holes through the hull.
•• Built on modified tanker hull with dynamic positioning outfitting.
•• Anchored or positioned with propellers correcting ships’ drift.
• Often used for drilling exploratory (‘wildcat’) wells and scientific drilling.
JACKUPSJACKUPS
JACKUPSJACKUPS
•• Usually towed to shallow locations and anchored using jack-like legs.
•• Legs lowered to seabed and hull jacked-up clear of the sea surface.
•• Used in waters of depths up to 160m.
TENDER ASSISTED DRILLINGTENDER ASSISTED DRILLING
TENDER ASSISTED DRILLINGTENDER ASSISTED DRILLING
•• Features self-erecting drilling units and tender support vessels.
•• Used in fields with relatively few wells and restrictions on topside weights.
•• Semi-submersible rigs are increasingly used in TAD to reduce platform topsides and jacket weight / cost.
