marine riser การใช้

• Basically, both production risers and drilling risers are both types of marine risers.
• Tools and fluids are moved within the marine riser as required to / from the well.
• Outfalls may also be constructed as an outfall tunnel or subsea tunnel and discharge effluent to the ocean via one or more marine risers with nozzles.
• The rig's mooring system revealed significant damage and the rig lost approximately of marine riser and a portion of the subsea well control system.
• The marine riser is connected to the wellhead on the sea bed and therefore the tensioner must manage the differential movements between the riser and the rig.
• A marine riser tensioner located on the drilling platform provides a near constant tension force adequate to maintain the stability of the riser in the offshore environment.
• When drilling an offshore well, a marine riser is connected to the well, and this is subjected to large environmental forces such as current and waves which are transferred to the conductor.
• The well integrity test was scheduled to take place after the installation of a three-ram capping stack over the lower marine riser package of the Deepwater Horizon semi-submersible rig on.
• Divers may work on marine risers ( conduits that extend a subsea oil well to a surface facility ) and blowout prevention stacks on all production rig types if the depth is within diving range.
• The rig was capable of operations at water depths up to and drilling down to approximately using an, 10, 000 PSI blowout preventer ( BOP ), and a outside diameter ( OD ) marine riser.
• At the bottom of the marine riser, the EDP and other components that connect the riser to the well and allow the well to be shut-in when required, constitute a'Lower Riser Package'( LRP ).
• The vessel is capable of drilling in water depths up to 3, 049 m ( 10, 000 ft ) using an, 15, 000 psi blowout preventer ( BOP ), and a outside diameter ( OD ) marine riser.
• The vessel is capable of drilling in water depths up to 8, 100 ft ( upgradable to 10, 000 ft ) using an, 15, 000 psi blowout preventer ( BOP ), and a outside diameter ( OD ) marine riser.
• For example, the rig's columns were strengthened to withstand some ice impact and the marine riser had a feature similar to a cow-catcher to keep floating ice off the marine riser that connected the rig to the well on the ocean bottom.

• Under normal operating conditions, the MODU / WIV ( which is floating on the sea surface ) is connected to the oil / gas well ( which is drilled in the sea bed ) by a vertical ( or near-vertical ) piece of steel pipe, called a marine riser.
• Jim Ingram stated that " on the second [ thud ], we knew something was wrong . " After the explosion, Adrian Rose stated that abnormal pressure had accumulated inside the marine riser and as it came up it " expanded rapidly and ignited . " Rose said the event was basically a blowout.
• ""'Transocean Marianas " "'is an Earl & Wright Sedco 700 design semi-submersible drilling unit capable of operating in harsh environments and water depths up to using an, 15, 000 psi blowout preventer ( BOP ), and a outside diameter ( OD ) marine riser.
• ""'Discoverer Clear Leader " "'is a double hulled dynamically positioned drillship, capable of operating in moderate environments and water depths up to 12, 000 feet ( 3, 657m ) using an, 15, 000 psi blowout preventer ( BOP ), and a outside diameter ( OD ) marine riser.
